ΓòÉΓòÉΓòÉ 1. About This Book ΓòÉΓòÉΓòÉ
This book is designed as a programmer's guide for the IBM SystemView Agent
Version 1 program (hereafter referred to as SystemView Agent). SystemView Agent
provides access to system components that have been defined according to the
Desktop Management Interface (DMI) standard by acting as an SNMP agent. These
components can be hardware or software in the system that have been defined in
the Management Information Format (MIF). Although the DMI itself is
protocol-independent, SystemView Agent can detect any DMI-enabled components in
the system and translate the MIF information into SNMP management information
bases (MIBs).
This book contains information for versions of the SystemView Agent program
that run in the following environments:
OS/2
AIX
Windows NT and Windows 95

ΓòÉΓòÉΓòÉ 2. Introducing the SystemView Agent and the DMI ΓòÉΓòÉΓòÉ
With the Simple Network Management Protocol (SNMP), the SystemView Agent
program provides remote management applications with access to DMI-enabled
products in a system. Local management applications that can communicate with
the DMI can also query and set MIF information for DMI-enabled components.
This book describes the steps necessary to design and implement management
applications and manageable products with DMI technology. The information
presented here is accompanied with examples of program code to help show how
the DMI elements can be implemented. All of the examples used in this book in
their complete form are in the the following directories:
For OS/2 installations, the DMI\EXAMPLES subdirectory within the
directory where you installed the SystemView Agent program.
For AIX installations, the /usr/lpp/sva/samples subdirectory.
For Windows NT/Windows 95 installations, the DMI\EXAMPLES subdirectory
within the directory where you installed the SystemView Agent program.
ΓòÉΓòÉΓòÉ 2.1. SystemView Agent and the Desktop Management Interface ΓòÉΓòÉΓòÉ
The Desktop Management Task Force (DMTF) is a vendor alliance. This alliance
was convened to streamline the management of diverse operating systems commonly
found in an enterprise. The DMTF includes industry-wide workgroups, which
identify the pieces of information that are necessary to manage specific
categories of devices.
As part of this effort, the DMTF has published a standard that is called the
Desktop Management Interface Specification.
The SystemView Agent program provides access to system components that have
been defined according to the DMI standard by acting as an SNMP agent. Although
the DMI itself is protocol-independent, SystemView Agent can detect any
DMI-enabled components in the system and translate the MIF information into
SNMP objects that conform to the management information base (MIB) format. This
MIF-to-MIB mapping is performed automatically by a DMI subagent provided with
SystemView Agent.
ΓòÉΓòÉΓòÉ 2.1.1. What is the Desktop Management Interface? ΓòÉΓòÉΓòÉ
The Desktop Management Interface (DMI) comprises a set of interfaces and a
service layer that mediate between management applications and components
residing in a system. The DMI is a free-standing interface that is not tied to
any particular operating system or management protocol.
In the context of the DMI, a component is a physical or logical element of a
system, such as a piece of hardware or software. The SystemView Agent program
can access information for components that you have defined for your system or
for components that are predefined by other products. The program code that
manages the component directly is referred to as the component instrumentation.
Information about a component is defined in a language that is called the
Management Information Format (MIF). The MIF file for a component describes all
aspects of that component that can be managed by an application. The MIF files
for the components in a system are kept in a MIF database, where they can be
accessed through the DMI.
Elements of the DMI describes the elements that make up the DMI.

When a new component is introduced to the system, the component installs the
component MIF in the MIF database and notifies the service layer that the
component is available. The component then notifies any registered management
applications of its presence by sending an unsolicited notification, or event,
to the service layer. The service layer forwards the event to the appropriate
management applications in the form of an indication.
If a component does have any instrumentation associated with it, the MIF file
for the component is composed of static information.
If a component is using instrumentation to provide access to its information,
the instrumentation can be one of the following types of programs:
Overlay Loaded only when the service layer receives a request for
information. After the request is satisfied, the overlay
program is unloaded.
Direct-interface Runs continuously as a separate process. When the service
layer receives a request, it passes control temporarily to the
direct-interface program, which retrieves the information and
passes it back to the service layer.
If a management application wants to display or change information for a
component, the application registers with the service layer. After
registration, the management application can access component information with
Get, Set, and List commands. Get and Set commands are used to read and write
MIF attributes that pertain to the manageable elements of a component.
The service layer receives requests from the management application through
the MI and forwards them to the component instrumentation through the CI. When
responses come back to the service layer from the component, the service layer
passes them back to the management application through the MI. By using the
DMI to transfer information:
The management application does not need to understand the mechanism by
which instrumentation gathers component information
The instrumentation does not need to understand the component protocol
used by the management application.
ΓòÉΓòÉΓòÉ 2.1.2. How Does SystemView Agent Use the DMI? ΓòÉΓòÉΓòÉ
The SystemView Agent program extends the use of the DMI by providing a MIF
conversion utility and a DMI subagent that performs mapping of DMI information
into SNMP MIB information. Each MIF file in the system can be translated to an
SNMP MIB with the conversion utility and then loaded in a remote SNMP
management application. The management application can send requests to the DMI
subagent, which in turn converts the SNMP request into a DMI request. The
conversion is performed again, in reverse, when the DMI response is returned.
This enables the SNMP management application to participate in active
management of DMI-enabled components.
The DMI subagent's ability to perform this MIF-to-MIB mapping enables an SNMP
management application to manage any component that implements the DMI.
ΓòÉΓòÉΓòÉ 3. Understanding the MIF ΓòÉΓòÉΓòÉ
Before you define the individual attributes that will populate your groups, you
must understand the Management Information Format (MIF). The MIF file is an
ASCII file that you create with a text editor to define the elements of your
component to the DMI. The DMI service layer maintains all installed MIFs in a
MIF database.
This section describes the MIF in detail and includes information on the
following topics:
Conventions
Common statements
Definitions
ΓòÉΓòÉΓòÉ 3.1. MIF Conventions ΓòÉΓòÉΓòÉ
The MIF has the following conventions to be followed:
Lexical conventions
Comments
Keywords
Data types
Constants
Definition block delimiters
Language statement
ΓòÉΓòÉΓòÉ 3.1.1. Lexical Conventions ΓòÉΓòÉΓòÉ
The character sets that can be used with the MIF conform to one of the
following standards:
The International Standards Organization document ISO 8859-1 (Latin
Alphabet No. 1)
The Unicode 1.1 specification
If a MIF is created according to the Unicode specification, the first two
octets of the MIF file must be X'0xFE' and X'0xFF'. If the service layer does
not detect these values in the MIF file, the service layer treats the file as
an ISO 8859-1 MIF.
There are four classes of tokens: keywords, integer constants, literal
strings, and separators. Blanks, tabs, newlines, carriage returns and comments
(known collectively as white space) are ignored except as they serve to
separate tokens, such as adjacent keywords and constants.
When interpreting tokens, the MIF is not case sensitive, unless the token is a
literal string enclosed within double quote (") characters. Case is retained
for the contents of a literal string. Literal strings separated by white space
are concatenated and stored as one literal string.
ΓòÉΓòÉΓòÉ 3.1.2. Comments ΓòÉΓòÉΓòÉ
Comments can be placed anywhere in the MIF file to annotate the file's
contents. Two forward slashes (\\) are used to indicate the beginning of a
comment, and the comment continues through the end of the line. Comments are
ignored when the MIF file is interpreted.
ΓòÉΓòÉΓòÉ 3.1.3. Keywords ΓòÉΓòÉΓòÉ
MIF Keywords displays the keywords that can be used in the MIF.

ΓòÉΓòÉΓòÉ 3.1.4. Data Types ΓòÉΓòÉΓòÉ
The following data types are supported by the MIF:
integer (or int) A 32-bit signed integer with no known semantics
integer64 (or int64) A 64-bit signed integer with no known semantics
gauge A 32-bit unsigned integer that can increase or decrease.
When a gauge reaches its maximum value (2[32]-1), it
continues to report the maximum value until the value
decreases below the maximum. The speedometer of an
automobile is an example of a gauge.
counter A 32-bit unsigned integer that never decreases. A counter
increases to its maximum value (2[32]-1 or 2[64]-1) and
reverts to zero when it reaches its maximum value. The
odometer of an automobile is an example of a counter.
counter64 A 64-bit unsigned integer that never decreases. A counter
increases to its maximum value (2[32]-1 or 2[64]-1) and
reverts to zero when it reaches its maximum value.
string(n) or displaystring(n) A displayable string of n octets. For ISO 8859-1
implementations, 1 octet per character; for Unicode
implementations, 2 octets per character.
The value n represents the maximum number of octets in the
string, although the actual number of octets in use might
be shorter than this maximum value. The length of the
string is stored in the first four octets, which are not
included in the value n. You do not need to zero-terminate
the string as you do in the C and C++ programming
languages. The length of the string represents the number
of octets in the string, not the number of characters.
The maximum value of n that the service layer can display
is 508.
octetstring(n) A string of n octets that might or might not be
displayable.
The value n represents the maximum number of octets in the
string, although the actual number of octets in use might
be shorter than this maximum value. The length of the
string is stored in the first four octets, which are not
included in the value n. You do not need to zero-terminate
the string as you do in the C and C++ programming
languages. The length of the string represents the number
of octets in the string, not the number of characters.
date A 28-octet displayable string.
Dates are defined according to the following format:
yyyymmddHHMMSS.uuuuuu+ooo
Where:
yyyy The year
mm The number of the month
dd The number of the day of the month
HHMMSS The hours, minutes, and seconds,
respectively
uuuuuu The number of microseconds
ooo The offset from universal time, coordinated
(UTC) in minutes. If east of UTC, the
number is preceded by a plus (+) sign, if
west of UTC, the number is preceded by a
minus (-) sign,
While the date value occupies only 25 octets, the date is
stored as a 28-octet field to account for memory
alignment. The last three octets are zeroes (/0).
For example, Wednesday, May 25, 1994, at 1:30:15 PM EDT
would be represented as:
19940525133015.000000-300
If necessary, values must be padded with leading zeroes to
conform to the specified format, as in 05 being used to
represent the month of May. If a value is not supplied for
a field, each character in the field must be replaced with
an asterisk (*).
ΓòÉΓòÉΓòÉ 3.1.5. Constants ΓòÉΓòÉΓòÉ
Integer values can be specified according to the following format:
Syntax Base
nnn Decimal
0nnn Octal
0xnnn or 0Xnnn Hexadecimal
Where n represents a digit in the appropriate base.
Literal strings are characters enclosed by double quote characters, such as
"This is an example of a string". Literal strings that are separated by white
space are concatenated and treated as one string for the purpose of
interpreting the MIF file.
The literal escape character is the backslash (\) and is used to enter the
following characters:
Sequence Character
\a Alert (ring terminal bell)
\b Backspace
\f Form feed
\n New line
\r Carriage return
\t Horizontal tab
\v Vertical tab
\\ Backslash
\" Double quote
\xnn Hexadecimal bit pattern. If the MIF file is in ISO 8859-1 format,
the bit pattern can be one to two digits (\0 to \ff); if the file is
in Unicode format, the bit pattern can be one to four digits (\0 to
\ffff).
\ooo Octal bit pattern. If the MIF file is in ISO 8859-1 format, the bit
pattern can be one to three digits (\0 to \377); if the file is in
Unicode format, the bit pattern can be one to six digits (\0 to
\177777). bit pattern, octal
ΓòÉΓòÉΓòÉ 3.1.6. Block Scope ΓòÉΓòÉΓòÉ
The definition blocks specified by the MIF are delimited by the start and end
keywords. When using start and end, you must specify another keyword to
indicate the type of definition you are creating. Definition Block Keywords in
the MIF displays the keywords for the different block definitions in the MIF
and indicates where each is used.

ΓòÉΓòÉΓòÉ 3.1.7. Language Statement ΓòÉΓòÉΓòÉ
The language statement is used to describe the human language used in the MIF
file. This statement is optional and appears before the start component
statement.
The syntax for the statement is:
language = "language string"
language string is a text string that identifies the language, dialect (as
territory), and character encoding.
The format of language string is:
language-code|territory-code|encoding
language-code is a two-letter code defined in ISO 639, territory-code is a
two-letter code defined in ISO 3166, and encoding is either iso8859-1 or
unicode.
For example, the language string "fr|CA|iso8859-1" indicates French Canadian,
with ISO 8859-1 (8-bit) encoding.
If any fields are not supplied, they are omitted, but the two vertical bars
must appear in the string. The default language string is "en|US|iso8859-1".
The encoding field is ignored in the MIF file because the first two bytes of
the file determine the encoding. However, the field is used when communicating
through the Management Interface (MI).
The language statement can appear only once in the MIF file.
If you translate a MIF file into a local language, translate only literal
strings such as names, descriptions, enumeration literals, and any comments in
the MIF. Do not translate class strings, language names, or keywords.
Note: The service layer supplied with the SystemView Agent does not support
Unicode and generates an error if it encounters a Unicode MIF.
ΓòÉΓòÉΓòÉ 3.2. Common Statements ΓòÉΓòÉΓòÉ
The following statements can be used in most MIF definitions:
Name statement
Description statement
ID statement
There are several statements that are specific to the group and attribute
definitions. These statements are described as part of their associated
definitions.
ΓòÉΓòÉΓòÉ 3.2.1. Name Statement ΓòÉΓòÉΓòÉ
The name statement is used within a definition to assign a short identifying
string to the definition. This statement is required for all definitions in the
MIF file, and only one name statement is allowed for each definition. The MIF
does not require that name statements be unique, with the exception of those
used in enumeration and path definitions. The name statements in these two
cases must be unique among those specified in other enumeration and path
definitions in the component definition.
The syntax for the name statement is:
name = "name string"
name string is defined by the component developer. The length of the string
must be less than 256 characters.
The content of the name statement is usually used for display to a user through
a management application, such as the DMI browser. Users can also change the
value of this string by editing the MIF file directly.
ΓòÉΓòÉΓòÉ 3.2.2. Description Statement ΓòÉΓòÉΓòÉ
The description statement is used within a definition to provide information
about the element being defined. The description statement can be used within a
component, group, or attribute definition, but you cannot specify more than one
description statement for a single definition.
The syntax for the description statement is:
description = "description string"
description string is defined by the component developer.
The content of the description statement is usually used for display to a user
through a management application, such as the DMI browser. Users can also
change the value of this string by editing the MIF file directly.
ΓòÉΓòÉΓòÉ 3.2.3. ID Statement ΓòÉΓòÉΓòÉ
The ID statement is used within a definition to assign a unique numeric
identifier (ID) to the definition. The DMI refers to the ID when naming items
at the API level and when mapping to network management protocols. The ID
statement is required for the attribute and table definitions and optional for
the group definition. The MIF allows only one ID statement for each definition.
Note: The component, path, and enumeration definitions do not use the ID
statement. The component ID is assigned to the component by the service layer
when the component is installed.
The syntax for the ID statement is:
id = n
n is defined by the component developer. The value of n must be a non-zero
32-bit unsigned integer. The ID must be unique only within the scope of the
definition in which it is specified. For example, all the attributes within a
particular group must have different ID values, but IDs are not required to be
unique across groups.
Because components and management applications use IDs for communication, users
are not allowed to change the values of an ID.
ΓòÉΓòÉΓòÉ 3.3. Definitions ΓòÉΓòÉΓòÉ
The MIF uses the following definitions to specify the manageable aspects of a
component:
Component definition
Path definition
Enumeration definition
Group definition
Attribute definition
Table definition
ΓòÉΓòÉΓòÉ 3.3.1. Component Definition ΓòÉΓòÉΓòÉ
The component definition is the highest-level definition specified in the MIF
file. All other elements of the MIF file are defined within the scope of the
component definition, and there can be only one component definition in a MIF
file.
The syntax for the component definition is:
start component
name = "component name"
[description = "description string"]
(contents of component definition here)
end component
ΓòÉΓòÉΓòÉ 3.3.2. Path Definition ΓòÉΓòÉΓòÉ
The path definition is used to specify the location of the files used for
active management of the component. The MIF file for a component can contain
more than one path definition, as long as the name statement for each path
definition is unique within the component definition.
The operating system identifiers used in the path definition include dos,
macos, os2, unix, win16, win32, win9x, and winnt. These identifiers are not
case sensitive.
If you specify a keyword of win32, you are indicating that the component
instrumentation referenced in this definition runs on either Windows NT or
Windows 95 (or greater). Use of winnt or win9x indicates that the
instrumentation runs only on the platform specified by the keyword.
The syntax for the path definition is:
start path
name = "name identifying instrumentation code"
win32 = "C:\\directory\\filename.dll"
os2 = "direct interface"
dos = "C:\\directory\\filename.com"
unix = "/directory/filename"
end path
The keyword direct interface in the example indicates that the component
instrumentation code is a continuously running process that is registered with
the service layer.
The value of the name statement can be used as part of the attribute definition
to invoke the instrumentation code indicated in the path definition. Read Value
Statement for more information about how the code is invoked.
ΓòÉΓòÉΓòÉ 3.3.3. Enumeration Definition ΓòÉΓòÉΓòÉ
The enumeration definition enables you to associate character strings with
signed 32-bit integers. The enumerated lists are then used by the component's
instrumentation code to pass the integer values through the DMI, enabling the
management application to display the corresponding text string.
The syntax of the enumeration definition is:
start enum
name = "enumeration name"
type = datatype
vvv = "literal string"
[xxx = "string literal"]
end enum
enumeration name is a unique name within the component.
The integer values specified by vvv and xxx can appear in the definition in any
order. It is not necessary to represent every number between the lowest and
highest values in the definition, as long as each value is unique within the
same enumeration definition.
You can use multiple enumeration definitions within a single component
definition. Enumeration definitions do not have ID or description statements.
Note: If you specify the same string but different integer values for multiple
entries in the enumerated list, the Management Information Format always
associates the string with the first integer value defined in the enumerated
list. If a management application requests the value for a subsequent instance
of the string, the value of the first instance of the string is returned.
ΓòÉΓòÉΓòÉ 3.3.4. Group Definition ΓòÉΓòÉΓòÉ
In a MIF file, groups are used to arrange one or more attributes into logical
sets. You can also use groups to represent tables, which are made up of arrays
of attributes. You can use multiple group definitions within a single component
definition.
The syntax of a group definition is:
start group
name = "group name"
class = "class string"
[id = nnn]
[description = "description string"]
[key = nnn[,mm]...]
[pragma = "pragma string"]
(attribute definitions go here)
end group
If you include an ID statement in the group definition, the value of the ID
statement must be unique among other groups within the component.
The relationship between the ID statement and the key statement in the group
definition affects whether the group is interpreted as a group, a table, or a
table template. ID and Key Statements in MIF describes how the two statements
can be used.

ΓòÉΓòÉΓòÉ 3.3.4.1. Class Statement ΓòÉΓòÉΓòÉ
The class statement is used within a group definition to identify the developer
of the group and the version information that applies to the group. All groups
that share the same value for the class statement must also share the same
attribute definitions, including the same type, access, storage, and ID
statements. The name, description, and value statements on the attribute
definitions can vary. Identical class strings indicate identical group
definitions. The conformance provided by the class statement enables management
applications to determine the semantics of the group's attributes. Only one
class statement is allowed for each group definition.
The syntax of the class statement is:
class = "class string"
class string generally takes the following form:
"defining body|specific name|version"
In this convention, defining body is the name of the organization, specific
name identifies the contents of the group, and version identifies the version
of the group definition. Spaces are significant in this convention, so that
"DMTF|ComponentID|1.0" is not interpreted as being the same as "DMTF |
ComponentID | 1.0".
Although the MIF does not require that any particular convention be used when
defining the class statement, any class statements that do not follow this
convention generate a warning message during the installation of the MIF file.
Because applications and service layers might use this convention when
obtaining information with the List Component command, component developers are
encouraged to use this convention.
If you are developing a component that does not use the entire set of
attributes defined by a class, specify the unsupported keyword in the
definitions for the unused attributes. Read Value Statement for more
information about using this keyword.
ΓòÉΓòÉΓòÉ 3.3.4.2. Key Statement ΓòÉΓòÉΓòÉ
When the attributes in a group define a row in a table, the group must contain
a key statement that identifies the attribute ID used as the index into the
table. Attributes that function as keys can be of any data type and identify no
more than one instance of a group. Each instance of a group represents a row of
a table. Only one key statement is allowed for each group definition.
The syntax of the class statement is:
key = n[,m]
n is the ID of the attribute that functions as the key for the table. If you
use more than one attribute to index a table, specify the values in the key
statement as integers separated by commas. When a management application sends
a request or when component instrumentation sends a response regarding
information in a table, the key values must be sent in the same order as they
are listed in the key statement.
Note: If you are using the DMI subagent to translate MIF information into SNMP
MIB information, do not specify an attribute with a data type of integer64
(int64) or counter64 as a key. The DMI subagent does not support 64-bit keys.
ΓòÉΓòÉΓòÉ 3.3.4.3. Pragma Statement ΓòÉΓòÉΓòÉ
The pragma statement is used to provide additional information related to the
group, but the contents of the statement are never queried or acted on by the
DMI.
The syntax of the pragma statement is:
pragma = "pragmakeyword:value[,pragmakeyword:value]"
Note: The only use for this statement defined in DMI 1.1 is to provide the
SNMP object identifier (OID) of the group to facilitate mapping of MIF
information to SNMP MIB information. For example:
pragma = "SNMP:1.2.3.4.5.6"
ΓòÉΓòÉΓòÉ 3.3.5. Attribute Definition ΓòÉΓòÉΓòÉ
An attribute is a piece of data related to a component. You organize your
attributes by defining them within one or more group definitions. Each group in
the component must have at least one attribute definition, although many
attribute definitions can appear within a single group definition.
The syntax of the attribute definition is:
start attribute
name = "attribute name"
id = nnn
[description = "description string"]
type = datatype
[access = method]
[storage = storage type]
[value = v | * "name" | "enumeration string"]
end attribute
The ID statement is required for the attribute definition and must have a value
that is unique among all other attribute definitions within the same group.
ΓòÉΓòÉΓòÉ 3.3.5.1. Type Statement ΓòÉΓòÉΓòÉ
The type statement describes the storage and semantic characteristics of the
attribute and is required in the attribute definition. Only one type statement
can be specified in the same attribute definition.
The syntax of the type statement:
type = datatype
datatype is usually one of the data types defined in Data Types.
You can also specify an enumerated list as the data type for a type statement.
In this case, the attribute is stored and treated as a signed 32-bit integer.
If you have already defined an enumerated list at the component level, you can
indicate it by name in place of datatype: for example, type = "Verify_Type"
If you are creating a new enumerated list with the type statement, you can
define the list inside the type statement:
type = start enum
enumeration definition
end enum
In this situation the enumeration definition does not require a name statement
because the enumerated list cannot be referred to outside the scope of this
attribute definition. If you specify a name, the value is ignored.
ΓòÉΓòÉΓòÉ 3.3.5.2. Access Statement ΓòÉΓòÉΓòÉ
The access statement determines whether the attribute value can be read or
written. The access statement is optional and can appear only once in the
attribute definition.
The syntax for the access statement is:
access = method
method can take the following values: read-only, read-write, write-only.
The access statement is not specified, the default access method used for the
attribute definition is read-only.
Note: It is highly recommended that keyed values be assigned an access type of
read-only.
If you are using the DMI browser to display a key attribute with an access type
other than read-only, do not attempt to change the key attribute's value or set
the attribute's value to be the same as that of another key attribute. This can
cause unpredictable results.
ΓòÉΓòÉΓòÉ 3.3.5.3. Storage Statement ΓòÉΓòÉΓòÉ
The storage statement provides management applications with information about
the attribute to assist in optimizing storage requirements. Only one storage
statement is allowed per attribute definition.
The syntax for the storage statement is:
storage = type
type can be one of the following:
Common The value of the attribute is typically limited to a small set of
possibilities, such as the clock speed of a CPU or the name of a
manufacturer.
Specific The value of the attribute can be one of a large number of
different values, such as the serial number of a device or a
timestamp value. Values that have a storage type of specific are
generally not suited for optimization.
If the storage statement is not specified on the attribute definition, the
default storage type for the attribute is specific.
ΓòÉΓòÉΓòÉ 3.3.5.4. Value Statement ΓòÉΓòÉΓòÉ
The value statement provides a value for the attribute being defined or a means
by which the value can be determined.
The syntax for the value statement is one of the following:
value = v
value = "enumeration value"
value = * "name"
value = unsupported
value = unknown
The values specified in the value statement include:
v The value v is used for read-only attributes whose values
do not change or for read-write values that are managed by
the service layer rather than by component
instrumentation. The value specified in the statement must
conform to the data type of the attribute. For example,
literal strings must be specified within double quotes.
Write-only attributes cannot specify a value of v.
"enumeration value" The value "enumeration value" can be either a text string
or integer value that references a previously specified
enumeration definition within the component or within this
attribute definition. The type statement for the attribute
must be an enumeration definition, as described in Type
Statement.
* "name" This value specifies the symbolic name of the component
instrumentation code that is used to read or write the
value for this attribute when a request is made to the
service layer. The name indicated by this value must have
been previously defined in a path definition within the
component definition.
unsupported This value is a reserved keyword and indicates to the
service layer that the attribute is not supported for this
component.
unknown This value is a reserved keyword and indicates to the
service layer that the attribute is supported but its
value is known.
The value statement is required unless you are defining a template for a
table, where it is optional. However, if you do provide a value within a
template, that value is used as the default value when populating the table.
If you do not specify a value for a template, no default value is used.
ΓòÉΓòÉΓòÉ 3.3.6. Populating Tables ΓòÉΓòÉΓòÉ
In the MIF, a table is composed of an array of group instances. Each instance
of a group is a row in the table. Defining a table can be done in one of two
ways:
By specifying a key statement on a group definition. In this case, the
values of the attributes within each row of the table are provided by the
component instrumentation.
By specifying the table's values within the MIF file itself.
The table definition actually identifies the data in the table rather than how
the data is stored or changed. When you populate a table with a table
definition, you identify a previous group definition in the component to be
used as a template for the table.
The syntax for the table definition is:
start table
name = "table name"
id = nnn
class = "class string"
{ v1[,v2...] }
[ { vn[, vm...] }
end table
The name statement is required for identification. The value of the ID
statement must be unique across all other group and table definitions in the
component. The class statement identifies the previous group definition that
is being used as the template for this table.
For each row in the table, the values are specified between braces and conform
to the format described by the value statement (Value Statement). The values
are separated by commas and listed from left to right according to the
attribute IDs that correspond to the values. The value of the attribute with
the lowest ID is listed first. If a value in the list is omitted, the default
value for the corresponding attribute is used if a default value is defined in
the template. If no default value is defined, specify a value in the table
definition. A row with too few commas is treated as a row with the trailing
number of requisite commas, and the values specified in the template are used
for the remaining attributes in the row.
A row with too few commas generates an error message from the DMI browser.
Sample Table Definition provides an example of how you can use a table
definition to specify attribute values.
Sample Table Definition
start table
name = "sample table"
id = 2
class = "group2 class"
{7,,,,,,,,,}
{8,8,8,8,6678,"row 8","octet","20011024123515.000000-300",543,8}
{9,-99,9,9,6767,"row 9","octet","99999999999.999999-999",333,20}
end table
When populating rows within a table, you must provide unique values for the
combination of attributes that make up the key. If the service layer is
managing a MIF file and the MIF file does not provide unique keys, the service
layer rejects the MIF file. As an example, consider a group definition acting
as a template, with two keys specified as first name and last name. If the
table is populated by two rows of attributes, it is acceptable for the values
of last name to be the same, as long as the values for first name are
different. In other words, the values "John Smith" and "Paul Smith" are
acceptable instances of the two keys, but "John Smith" and "John Smith" are
not.
A table definition must be defined after the group definition to which it
refers. You can specify the same template for multiple table definitions, as
long as each table definition has a different ID.
ΓòÉΓòÉΓòÉ 3.3.7. ComponentID Group ΓòÉΓòÉΓòÉ
The ComponentID group is a standard group that is required for every MIF file.
This group provides basic identification of the component and represents the
minimum amount of information that a component developer is expected to
provide.
The ID for the ComponentID group is 1. If an attribute is not supported by the
component or is not applicable to the component, the value for the attribute
should be specified by the unsupported keyword.
The value of the class statement for this group is "DMTF|ComponentID|1.0".
The attributes for the group are described in Attributes for ComponentID Group.

The instrumentation returns one of the following values:
0 An error occurred; check status code.
1 This component does not exist.
2 The verify is not supported.
3 Reserved
4 This component exists, but the functionality is untested.
5 This component exists, but the functionality is unknown.
6 This component exists and is not functioning correctly.
7 This component exists and is functioning correctly.
ΓòÉΓòÉΓòÉ 3.4. Defining Events in the MIF ΓòÉΓòÉΓòÉ
The definition of events for a component is done in the MIF file with the
following groups:
Event Generation Group
Event State Group
The event generation group defines the format for events issued by the
component. A management application can issue DMI list commands on the
attributes in this group and display information about the cause of the event.
If appropriate, information about potential solutions to the problem reported
by the event can also be displayed.
The event state group defines the format of state-based events, which are
issued when the state of the instrumented component changes. For example, a
state-based event might be generated when a device enters a problem state or
when a problem state is resolved.
ΓòÉΓòÉΓòÉ 3.4.1. Event Generation Group ΓòÉΓòÉΓòÉ
The event generation group definition serves as a template that a management
application can use to associate values received in the Indication buffer with
enumeration display strings. Although values are specified in the group
definition to ensure proper processing of the MIF file, the management
application accesses the appropriate values directly from the Indication
buffer.
The general structure of the event generation group is:
start group
name = "Event Generation"
class = "EventGeneration|<specific name>|001"
id = nnn
key = nnn[,mmm]...
(attribute definitions here)
end group
The string defined in the class statement is unique for each event generation
group and is specified in the following format:
<defining-body>^^<specific-name-of-associated-group>
The contents of the specific-name-of-associated-groupfield indicates the name
of the group to which the events defined in the event generation group
correspond.
Component developers can define additional attributes to a standard event
generation group by using a proprietary-extension field that is appended to the
class statement. The format for the class statement in this case is:
<defining-body>^^<specific-name-of-assoc-grp>^^<proprietary-extension>
When specifying a proprietary extension, it is recommended that you use the
complete, registered name of your corporate entity. This ensures that the
specific-name field in the class statement is unique.
When defining multiple event generation groups for a single associated group,
place the event generation groups immediately after the associated group in the
MIF file and use sequential IDs.
ΓòÉΓòÉΓòÉ 3.4.1.1. Boolean Definition ΓòÉΓòÉΓòÉ
The following Boolean definition is used in specifying the value of some
attributes in the event generation group:
start enumeration
name = "BOOL"
0 = "False"
1 = "True"
end enumeration
ΓòÉΓòÉΓòÉ 3.4.1.2. Event Type ΓòÉΓòÉΓòÉ
The event type attribute indicates the reason that the event was generated.
This attribute is required in the event generation group.
The syntax of the event type definition is:
name = "event type"
id = 1
description = "The type of event that has occurred."
type = <enumeration>
access = read-only
storage = specific
value = 0
The enumeration list is unique to the event generation group being defined and
is not specified in this example.
ΓòÉΓòÉΓòÉ 3.4.1.3. Event Severity ΓòÉΓòÉΓòÉ
The event severity attribute indicates the category of the event that has been
generated. This attribute is required in the event generation group.
The syntax of the event severity definition is:
name = "event severity"
id = 2
description = "The severity of this event."
type = start enumeration
0x001 = "Monitor"
0x002 = "Information"
0x004 = "OK"
0x008 = "Non-Critical"
0x00A = "Critical"
0x00C = "Non-Recoverable"
end enumeration
access = read-only
storage = specific
value = 0
The enumeration list in this definition cannot be changed.
The events with a severity of Monitor and Information are used to provide
information about the event but do not indicate the state of the component that
generated the event. Severities of OK, Non-Critical, Critical, and
Non-Recoverable, however, are state-based.
Monitor Used for periodic events generated by transaction-oriented
components.
Information Used to indicate change that is not considered a problem.
Information events are not periodic or expected.
OK Used to indicate that the component has entered the normal
state, either for the first time (on initialization, for
example) or after a problem state (Non-Critical, Critical,
Non-Recoverable) has cleared.
Non-Critical Used to indicate that a problem needs to be corrected,
although no time period for correction is associated.
Critical Used to indicate that a problem needs to be corrected within
a specific time period.
Non-Recoverable Used to indicate that a problem needs to be corrected
immediately. Non-Recoverable events indicate serious failure
situations.
ΓòÉΓòÉΓòÉ 3.4.1.4. Event Is State-Based ΓòÉΓòÉΓòÉ
This attribute indicates whether the component that generates an event is
state-based. If the component is state-based, an event is generated whenever
the component's state changes or when any problem state is cleared. If the
component is not state-based, an event is generated for any condition of
interest that develops, but no event is generated when the condition clears.
This attribute is required in the event generation group.
The syntax of the event-is-state-based definition is:
name = "event is state-based"
id = 3
description = "The value of this attribute determines "
"whether the Event being reported is a "
"state-based Event or not. If the value of "
"this attribute is TRUE then the Event is state-"
"based. Otherwise the Event is not state-based."
type = "BOOL"
access = read-only
storage = common
value = "False"
A value of True indicates that the event is state-based.
ΓòÉΓòÉΓòÉ 3.4.1.5. Event State Key ΓòÉΓòÉΓòÉ
This attribute identifies a row in the event state group associated with the
component definition that contains this event generation group. The value of
the current state attribute (Current State) within the specified row indicates
the current state of the event. If the generated event is not state-based, the
value of the event state key attribute is ignored.
This attribute is required in the event generation group.
The syntax of the event state key definition is:
name = "event state key"
id = 4
description = "This attribute holds the key identifying a row of "
"the Event State group within the Component in "
"which the event generator group is located. The "
"Current State attribute within the row contains "
"the current state of this state-based event. The "
"current state can be one of the four severities: "
"OK, Non-Critical, Critical, and Non-Recoverable."
type = integer
access = read-only
storage = specific
value = 0
ΓòÉΓòÉΓòÉ 3.4.1.6. Associated Group ΓòÉΓòÉΓòÉ
The associated group attribute contains the value of the class statement of the
associated group.
This attribute is a keyed attribute and is required in the event generation
group.
The syntax of the associated group definition is:
name = "associated group"
id = 5
description = "The class string of the group that is associated "
"with the events defined in this Event Generation "
"group."
type = string ( <size> )
access = read-only
storage = common
value = "<class string>"
If a management application discovers an event generation group, it can
determine the associated group by issuing a DmiListFirstComponentCmd with a
class filter of EventGeneration|| and a keylist containing the value of this
attribute.
ΓòÉΓòÉΓòÉ 3.4.1.7. Event System ΓòÉΓòÉΓòÉ
The event system attribute provides information about the functional system of
the product that generated the event. A management application can use the
values of this attribute and the event subsystem attribute (Event Subsystem) to
construct a simple message describing the event.
This attribute is required in the event generation group.
The syntax of the event system definition is:
name = "event system"
id = 6
description = "The major functional aspect of the product "
"causing the fault."
type = <enumeration>
access = read-only
storage = specific
value = 0
The enumeration list is unique to the event generation group being defined and
is not specified in this example.
ΓòÉΓòÉΓòÉ 3.4.1.8. Event Subsystem ΓòÉΓòÉΓòÉ
The event subsystem attribute provides information about the functional
subsystem of the product that generated the event. A management application can
use the values of the event system attribute (Event System) and this attribute
to construct a simple message describing the event.
This attribute is required in the event generation group.
The syntax of the event subsystem definition is:
name = "event subsystem"
id = 7
description = "The minor functional aspect of the product "
"causing the fault."
type = <enumeration>
access = read-only
storage = specific
value = 0
The enumeration list is unique to the event generation group being defined and
is not specified in this example.
ΓòÉΓòÉΓòÉ 3.4.1.9. Event Solution ΓòÉΓòÉΓòÉ
The event solution attribute describes a possible solution to the problem that
caused the event. The contents of this attribute might be recommended actions
for the user of a management application. If the severity of the event is
Critical, this attribute might also specify a time period for recovery action.
This attribute is optional in the event generation group.
The syntax of the event solution definition is:
name = "event solution"
id = 8
description = "A solution to the problem that caused the "
"event."
type = <enumeration>
access = read-only
storage = specific
value = 0
The enumeration list is unique to the event generation group being defined and
is not specified in this example.
ΓòÉΓòÉΓòÉ 3.4.1.10. Instance Data Present ΓòÉΓòÉΓòÉ
This attribute indicates to the management application that the second event
block within the Indication data structure contains instance-specific data.

event.
This attribute is optional in the event generation group.
The syntax of the instance-data-present definition is:
name = "instance data present"
id = 9
description = "Indicates whether the second event block "
"contains instance-specific data."
type = "BOOL"
access = read-only
storage = specific
value = "False"
ΓòÉΓòÉΓòÉ 3.4.1.11. Vendor Specific Message ΓòÉΓòÉΓòÉ
This attribute is used to pass displayable string data to a management
application. The string can be in any locale, as long as it can be displayed
using the ISO 8859-1 character set. This definition does not specify a size
limit for the string.
This attribute is optional in the event generation group.
The syntax of the vendor-specific-message definition is:
name = "event message"
id = 10
description = "Auxiliary information related to the event."
type = string(<size>)
access = read-only
storage = specific
value = ""
This attribute, along with the vendor specific data attribute (Vendor Specific
Message), is designed to provide event generators and consumers with an
efficient, private interface with which to pass arbitrary information. This can
be useful to manufacturers that develop both component instrumentation and
management applications.
ΓòÉΓòÉΓòÉ 3.4.1.12. Vendor Specific Message ΓòÉΓòÉΓòÉ
This attribute is used to pass arbitrary data to a management application. This
definition does not specify a size limit for the octet string.
This attribute is optional in the event generation group.
The syntax of the vendor-specific-data definition is:
name = "vendor specific data"
id = 11
description = "Auxiliary information related to the event."
type = octetstring(<size>)
access = read-only
storage = specific
value = ""
This attribute, along with the vendor specific message attribute (Vendor
Specific Message), is designed to provide event generators and consumers with
an efficient, private interface with which to pass arbitrary information. This
can be useful to manufacturers that develop both component instrumentation and
management applications.
ΓòÉΓòÉΓòÉ 3.4.2. Event State Group ΓòÉΓòÉΓòÉ
The event state group is a table that contains the current state of state-based
events within the component. The group definition has a key that acts as a
unique identifier for each row of the table. A row in the table holds
information about a unique event type that is generated from a given event
generation group in the component.
An example of the general structure of the event state group is:
start group
name = "Event State"
class = "DMTF|Event State|001"
id = nnn
key = nnn
(attribute definitions here)
end group
You can also maintain the current state information for proprietary state-based
events by adding more rows within this group that reference the proprietary
event generation group. Refer to Event Generation Group for information on
doing this using the event generation group attribute in the event state group
definition.
ΓòÉΓòÉΓòÉ 3.4.2.1. Event Index ΓòÉΓòÉΓòÉ
The event index attribute specifies the index into the event state table.
The syntax of the event index definition is:
name = "event index"
id = 1
description = "A unique index into the Event State table"
type = integer
access = read-only
storage = common
value = 0
ΓòÉΓòÉΓòÉ 3.4.2.2. Event Generation Group ΓòÉΓòÉΓòÉ
This attribute contains the class string of the event generation group within
the component definition that defines the indication format for the related
event. The ComponentID of the component with which the event is associated is
specified in the header of the Indication data structure.
The syntax of the event-generation-group definition is:
name = "event generation group class"
id = 2
description = "The Class String of the event generator group "
"within the generating Component"
type = string (256)
access = read-only
storage = common
value = 0
For each row in the event state group, this attribute identifies the ID of the
event generation group that defines the event type represented by the row. A
management application can scan for state-based events in a system by using a
class filter of "|EventState|" to discover instances of the event state group
and then scanning the rows of the group for state-based events.
If you are adding rows to the event state group for proprietary state-based
events, specify the class string of the proprietary event generation group as
the value for this attribute in the additional rows.
ΓòÉΓòÉΓòÉ 3.4.2.3. Event Type ΓòÉΓòÉΓòÉ
The event type attribute indicates the reason that the event was generated. The
value of this attribute corresponds to an item in the enumeration list
specified by the event type attribute in the associated event generation group
definition. The specific event generation group is identified by the event
generation group attribute (Event Generation Group).
The syntax of the event type definition is:
name = "event type"
id = 3
description = "Integer value that identifies one of the "
"Event types enumerated in the associated Event "
"Generation group."
type = integer
storage = common
value = 0
ΓòÉΓòÉΓòÉ 3.4.2.4. Current State ΓòÉΓòÉΓòÉ
The current state attribute indicates the severity of the specific event type
represented by this row of the event state group.
The syntax of the current state definition is:
name = "current state"
id = 4
description = "The current state of the Event type identified "
"by Event Type attribute in this row."
type = start enum
0x0004 = "OK"
0x0008 = "Non-Critical"
0x000A = "Critical"
0x000C = "Non-Recoverable"
end enum
access = read-only
storage = specific
value = "OK"
The enumeration defined in this attribute is a subset of the enumeration
defined in the event severity attribute in the event generation group
definition.
ΓòÉΓòÉΓòÉ 3.4.2.5. Associated Group Keys ΓòÉΓòÉΓòÉ
This attribute is used to identify an instance of the associated group that is
likely to have generated the event. Depending on how the associated group is
defined, there might be multiple keys, each of a different type. This attribute
represents such a list of keys with an encoded string consisting of a list of
integers separated by commas, with no spaces.
The syntax of the associated-group-keys definition is:
name = "associated group keys"
id = 5
description = "A list of integer keys that identify the instance "
"of the Associated Group that actually generated "
"the state-based event. The list of integer keys "
"are represented in the value of this attribute as "
"a string containing a comma-separated list of "
"integers. The management application must parse "
"this string to obtain the list of integer keys."
type = string(256)
access = read-only
storage = specific
value = ""
ΓòÉΓòÉΓòÉ 4. Using the DMI Management Interface ΓòÉΓòÉΓòÉ
This chapter describes how a management application communicates with the DMI
through the Management Interface (MI). A management application requests
information about components in the system by issuing the DMI Get, Set, and
List commands. However, before it can manage a component in the system, the
application must register with the service layer for that particular system.
Once registered, the application can issue commands, as well as receive
notifications of indications. It is the responsibility of the management
application to have program code in place to process the error codes returned
by the service layer.
This chapter describes how a management application communicates with the MI,
including the registration process that the application must use and the status
codes that the service layer returns.
ΓòÉΓòÉΓòÉ 4.1. Invoking a Command through the Management Interface ΓòÉΓòÉΓòÉ
Because the DMI is a data interface, all commands are specified with data
blocks. In order for a management application to send a command block to the
service layer, the application builds the command with the DmiMgmtCommand block
and any following blocks and then issues the DmiInvoke() function call.
The DmiInvoke() function call sends the command to the service layer for
processing. The C-language prototype for this call is:
unsigned long DmiInvoke(PTR command)
command is the complete command block. The return result is a 32-bit status
value that indicates whether the command succeeded or failed. The possible
status values are described in Status Codes.
While it processes the command, the service layer immediately returns control
to the management application. The management application can then continue
processing and issue additional commands, but the application cannot re-use the
same DmiMgmtCommand buffer that it previously sent to the service layer.
Simultaneous commands from a management application must use different
DmiMgmtCommand blocks. When the service layer is finished processing the
command, it notifies the management application by calling the pConfirmFunc()
function that was given when the management application originally registered
with the service layer. At that point, the management application can re-use
the DmiMgmtCommand block.
The DMI specification does not include a time-out policy. If a management
application issues a command and does not appear to get a response, the
application should issue a cancel command. Implementing DMI on OS/2 describes
how the SystemView Agent incorporates time restrictions on some operations.
For a description of the DmiMgmtCommand block and its contents, read
DmiMgmtCommand Command Block.
ΓòÉΓòÉΓòÉ 4.2. Canceling a Command ΓòÉΓòÉΓòÉ
A management application can cancel an outstanding command by using the
DmiMgmtCommand block. If the command being cancelled is performing actions on
multiple attributes, the command is halted as soon as possible within the
targeted command list.
To cancel a command, set the following fields in the DmiMgmtCommand block to
the specified values:
Variable Value
iCommand 0x102 (DmiCancelCmd)
iMgmtHandle The value originally assigned by the service layer when the
application registered. This value identifies the management
application.
iCmdHandle The value that identifies the handle of the outstanding
command. The management application must ensure that the value
of iCmdHandle is unique among all outstanding commands from
that management application.
For a description of the DmiMgmtCommand block and its contents, read
DmiMgmtCommand Command Block.
ΓòÉΓòÉΓòÉ 4.3. Registering with the Service Layer ΓòÉΓòÉΓòÉ
Before initiating any management activity through the DMI, a management
application must register with the service layer. The registration process
enables the service layer to provide services for the management application,
such as forwarding indications from components in the system.
The following registration commands are described in the command blocks
chapter, according to their command block structure:
DmiRegisterMgmtReq (DmiRegisterMgmtReq Command Block)
DmiRegisterCnf (DmiRegisterCnf Command Block)
Because the service layer maintains the entry points for a management
application until the application unregisters, the application cannot provide
different entry points for different commands. However, if for some reason a
management application needs to use multiple entry points to the service
layer, the application can do one of the following:
Register a dispatch routine as its entry point and then manually dispatch
reports to the appropriate code.
Register with the service layer more than once, giving different entry
points for each registration. For each registration, the service layer
assigns a new management handle, so the appropriate handle can be used
when issuing a command. Because each registration adds processing
overhead to the service layer, this approach should be used only when the
first method is not practical.
In addition to the management application's entry points, the service layer
must keep the value of the osLanguage string in the command block. This value
identifies the language and character set that the service layer uses when
sending indications to the management application.
ΓòÉΓòÉΓòÉ 4.4. Unregistering with the Management Interface ΓòÉΓòÉΓòÉ
To unregister a management application from the service layer, send a
DmiMgmtCommand block with the following values:
Variable Value
iCommand 0x101 (DmiUnregisterMgmtCmd)
iMgmtHandle The value originally assigned by the service layer when the
application registered. This value identifies the management
application.
For a description of the DmiMgmtCommand block and its contents, read
DmiMgmtCommand Command Block.
ΓòÉΓòÉΓòÉ 4.5. Processing Indications ΓòÉΓòÉΓòÉ
An indication is an unsolicited report that is not expected by the receiving
application. Registration provides a mechanism for management applications to
register for notification of indications.
The service layer maintains a list of entry points for registered management
applications. Each entry point is called when the service layer generates an
indication. The called routine must immediately return control to the service
layer and perform any operations necessary based on the indication. The routine
informs the service layer that it has finished processing the report by calling
the function pResponseFunc(), as given in the DmiIndicate block.
For a description of the DmiIndicate block and its contents, read DmiIndicate
Command Block.
Each registered indication entry point is called for every indication.
Management applications must unregister their entry points before terminating.
ΓòÉΓòÉΓòÉ 4.6. Using List Commands ΓòÉΓòÉΓòÉ
The List commands provide read access to a system's MIF database and enable a
management application to query the manageable entities within a system. These
commands allow a system to be probed to determine its characteristics without
incurring the overhead of executing the code required to retrieve current
values. All list commands take the following form:
Form Behavior
List Accesses lists randomly
List First Accesses lists from the start
List Next Accesses lists in sequential order
Specific List commands return information on individual entities. List First
and List Next commands return data in a bulk fashion. There are also List
commands to retrieve the description fields from a system.
ΓòÉΓòÉΓòÉ 4.6.1. Listing Component Information ΓòÉΓòÉΓòÉ
List Component commands request a list of the components in a system. This
command can be used to return all components in a system or only those with a
certain group class. Calls for all components are referred to as unfiltered,
and calls for a specific group class are filtered.
There are three List Component commands:
DmiListComponentCmd
Requests data for a specific component.
DmiListFirstComponentCmd
Requests data for the first component in a system. The
component with the lowest component ID is considered the first
component in the system. This will always be the service layer
itself, which always has component ID of 1. The service layer
fills in as many component definitions as the size of the
confirm buffer allows.
DmiListNextComponentCmd
Requests data for the component instrumentation whose ID is the
next highest value after the one passed in the
DmiListComponentCmd block. The service layer fills in as many
component definitions as the size of the confirm buffer allows.
For a description of the DmiListComponentReq block used to issue these List
commands, read DmiListComponentReq Command Block.
The service layer does not contact any component instrumentation when
performing List commands. It relies on the MIF database for all information.
When specifying keys that require components to be run before the values can
be determined, the service layer returns the key as a possible match. Any
matches from data in the MIF database are listed as hard matches. It is the
responsibility of the management application to follow up with each component
instrumentation and convert possible matches into hard matches.
ΓòÉΓòÉΓòÉ 4.6.2. Listing Group Information ΓòÉΓòÉΓòÉ
List Group commands request a list of the groups in a component.
There are three List Group commands:
DmiListGroupCmd
Requests data for a specific group.
DmiListFirstGroupCmd
Requests data for the first group in a specified component. The
group with the lowest group ID is considered the first group in
the component. The service layer fills in as many groups as the
size of the confirm buffer allows.
DmiListNextGroupCmd
Requests data for the group whose ID is the next highest value
after the one passed in the DmiListGroupReq block. The service
layer fills in as many groups as the size of the confirm buffer
allows.
For a description of the DmiListGroupReq block used to issue these List
commands, read DmiListGroupReq Command Block.
ΓòÉΓòÉΓòÉ 4.6.3. Listing Attribute Information ΓòÉΓòÉΓòÉ
List Attribute commands request the attribute definitions within a group for a
given component. They do not retrieve the current attribute values.
There are three List Attribute commands:
DmiListAttributeCmd
Requests data for a specific attribute.
DmiListFirstAttributeCmd
Requests data for the first attribute in a group. The attribute
with the lowest attribute ID is considered the first attribute
in the group. The service layer fills in as many attribute
definitions as the size of the confirm buffer allows.
DmiListNextAttributeCmd
Requests data for the attribute whose ID is the next highest
value after the one passed in the DmiListAttributeReq block.
The service layer fills in as many attribute definitions as the
size of the confirm buffer allows.
For a description of the DmiListAttributeReq block used to issue these List
commands, read DmiListAttributeReq Command Block.
ΓòÉΓòÉΓòÉ 4.6.4. Listing Description Information ΓòÉΓòÉΓòÉ
List Description commands request the description field for the component,
group, or attribute specified. These calls are separated from the other list
calls because the description fields might be of substantial size and might not
be used or needed in some cases.
There are three List Description commands:
DmiListComponentDescCmd
Requests description of components
DmiListGroupDescCmd
Requests description of groups
DmiListAttributeDescCmd
Requests description of attributes
For a description of the DmiListDescReq block used to issue these List
commands, read DmiListDescReq Command Block.
ΓòÉΓòÉΓòÉ 4.6.5. Getting Attribute Information ΓòÉΓòÉΓòÉ
The difference between List and Get commands is that a List command returns MIF
information about an object, and a Get command requests the actual value for
the object.
The DmiGetAttributeCmd command is used to request the current values of
attributes within groups. For a description of the DmiGetAttributeReq block
used to issue this command, read DmiGetAttributeReq Command Block.
ΓòÉΓòÉΓòÉ 4.6.6. Setting Attribute Information ΓòÉΓòÉΓòÉ
To enable concurrent access by multiple management applications, the DMI allows
more than one pass through a list of Set commands. The first pass is a call to
reserve the attributes. This reserve command tests a component to verify that a
set operation on a given attribute can occur and asks the component
instrumentation to validate a set operation without performing the set
operation. The component instrumentation must validate the parameters of the
call and reserve any resources that would be required if the set command were
issued.
A positive response from the reserve command indicates that the component
instrumentation has validated the parameters and reserved any resources that
might be required to perform the set operation. A negative response from the
command indicates that the component instrumentation is unable to perform the
set operation.
If all the attributes in the list returned successfully from the reserve
operation, the management application typically issues a Set command for each
attribute.
If a reserve fails, the management application might want to release each of
the attributes it previously reserved. Releasing attributes allows the
component instrumentation to deallocate any resources it had acquired. The task
of setting attributes back to their previous values is the responsibility of
the management application.
There are three Set commands:
DmiSetAttributeCmd Sets the value for a specified attribute
DmiSetReserveAttributeCmd Reserves a specified attribute for a subsequent set
operation
DmiSetReleaseAttributeCmd Releases a specified attribute
For a description of the DmiSetAttributeReq block used to issue these Set
commands, read DmiSetAttributeReq Command Block.
ΓòÉΓòÉΓòÉ 4.6.6.1. Reserving Attributes ΓòÉΓòÉΓòÉ
Reserving an attribute verifies that the set operation is valid. This ensures
that a subsequent set operation will be successfully issued. However, it is not
a locking operation. A management application can never assume exclusive
control of a component.
The component instrumentation that receives the Reserve command is responsible
for testing the arguments to verify that the set operation can be performed.
The testing verifies that the arguments are within range and allocates and
reserves any resources that might be needed to ensures the success of a
subsequent set operation.
After a successful set operation, the component instrumentation automatically
releases any resources that it has reserved. The management application does
not need to explicitly issue a Release command after a set.
The component instrumentation requires that all Reserve commands be followed by
either Set or Release commands to perform the set operation or to release the
reserved resources. The failure of the management application to issue either
command is considered a catastrophic failure and is outside the scope of the
component instrumentation's responsibility to try to correct.
If a management application requests that multiple attributes be reserved and
one of the reservations fails, the service layer returns the attribute where
the command failed. It is the responsibility of the management application to

ΓòÉΓòÉΓòÉ 4.6.6.2. Releasing Attributes ΓòÉΓòÉΓòÉ
The Release command is used when the caller wishes to decommit from a set
operation after a reserve has been issued.
ΓòÉΓòÉΓòÉ 4.6.7. Getting Attribute Information by Row ΓòÉΓòÉΓòÉ
Get Row commands request the values of all the attributes in a particular
group. Because groups can be a scalar set of attributes or can be arranged as
tables-arrays of sets of attributes-it is more convenient to consider them as
rows. Groups used as tables include keys to specify the desired instance (or
row) of the group.
There are three Get Row commands:
DmiGetRowCmd
Requests the values of attributes from a specific group or
specific row of a table.
DmiGetFirstRowCmd
Requests the values of the attributes in the first row of a
table. This is the same as DmiGetRowCmd for non-tabular groups.
DmiGetNextRowCmd
Requests the values of the attributes of the row after the row
whose key is passed in the command block.
For a description of the DmiGetRowReq block used to issue these Set commands,
read DmiGetRowReq Command Block.
Note for Component Developers Note that the command can be asking for key
values or for attribute values. To determine which, the component
instrumentation must compare the iGroupKeyCount field of DmiGetRowReq to
the iGroupKeyCount field of DmiGetRowCnf. If the key count in the confirm
block is less than the key count of the request block, the service layer
is requesting that the next key value be returned.
The key value to return for the DmiGetFirstRowCmd command is the value of
the next key attribute in the first row of the table. For the
DmiGetNextRowCmd command, the key values in the DmiGetRowReq structure
should be inspected to determine the current row. Then the value in the
succeeding row should be returned.
The DmiGetRowCnf structure is always built by the service layer, and the
value of oGroupKeyList specifies the start of DmiGroupKeyData structures.
The pCnfBuf member of DmiCiCommand points to the position in the confirm
buffer where the key value should be placed. The value of iGroupKeyCount
should be incremented, but the iCnfCount member of the DmiMgmtCommand
should not.
ΓòÉΓòÉΓòÉ 4.7. Status Codes ΓòÉΓòÉΓòÉ
Status codes are 32-bit unsigned values. The error codes returned by an
operating system are not passed back to a management application. Instead, the
service layer maps operating system errors into its error range. This insulates
management applications from operating system details. Error codes from
components are listed in the component's MIF file.
ΓòÉΓòÉΓòÉ 4.7.1. Non-error Condition Codes ΓòÉΓòÉΓòÉ
Non-Error Condition Codes displays the status codes used to indicate non-error
conditions.

ΓòÉΓòÉΓòÉ 5. Using the DMI Component Interface ΓòÉΓòÉΓòÉ
This chapter describes how a component communicates with the DMI through the
Component Interface (CI) and how component instrumentation registers with the
service layer and send indications.
Calls from the service layer through the CI use only attribute, group and key
identifiers for naming. By the time the component instrumentation is reached,
the service layer has resolved the component ID. Indications sent from the
component instrumentation through the CI also need the component ID so that the
service layer can identify the component instrumentation.
The mechanics of the communication from the service layer to the component
instrumentation are specific to the operating system environment. The entry
point function calls that the component instrumentation must respond to are
DmiCiInvoke() and DmiCiCancel().
The service layer is responsible for launching the component instrumentation,
if necessary, and for passing along the command blocks.
ΓòÉΓòÉΓòÉ 5.1. Installing a Component ΓòÉΓòÉΓòÉ
A component identifies itself to the management system by installing a MIF file
into the MIF database. The component installs the MIF file the first time it is
introduced to the system. This is the only time that the component needs to
perform this installation.
A MIF is installed and removed using the DmiCiInstall and DmiCiUninstall
commands. These are the only primitives provided to manipulate the MIF
database. There are no MIF database modification mechanisms. If an installed
MIF requires modification, it must be removed, modified, and then re-installed.
Upon installation or removal of a MIF file, the service layer issues an
indication to all registered management applications.
The installation can optionally include files that provide language mapping and
mapping logic between the MIF file and other management information standards.
For a description of the DmiCiInstallData block issued when installing a
component, read DmiCiInstallData Command Block.
On successful return, iComponentId is set to a numeric ID assigned by the
service layer. This ID uniquely identifies the component described by the
installation. This system-specific ID is stored by the service layer in the MIF
database. The MIF database is a persistent data store, so the component ID,
once assigned, remains the same until the component is removed. The component
must remember this component ID, as it is used when issuing indications or when
the component is removed from the system.
Upon successful installation, the service layer sends an indication to every
management application that is currently registered with it. If the
installation created a new component, the value of iIndicationType in the
DmiIndicate block is 2. If the installation resulted in any additional MIFs
being added to an existing component, the value of iIndicationType is 4. In
both cases, the indication data is a DmiListComponentCnf block. The DmiIndicate
function call is described in DmiIndicate Command Block.
ΓòÉΓòÉΓòÉ 5.2. Removing a Component ΓòÉΓòÉΓòÉ
Removing a component from the MIF database effectively removes the component
from further participation in the management system. In the DMI, removing a
component is called uninstalling.
Removing a component from the MIF database does not mean the component is not
present in the computer system. The component is still in the system, but the
management system is not aware of it.
To remove a component from the MIF database, the component instrumentation
fills out a DmiCiUninstallData block and sends it to the service layer with the
DmiInvoke() function call.
For a description of the DmiCiUninstallData block issued when installing a
component, read DmiCiUninstallData Command Block.
Upon successful removal, the service layer sends an indication to every
management application that is currently registered with it. The value of
iIndicationType in the DmiIndicate block is 3, and the indication data is a
DmiListComponentCnf block.
ΓòÉΓòÉΓòÉ 5.3. Invoking a Command ΓòÉΓòÉΓòÉ
The component instrumentation must provide an entry point so the service layer
can send command blocks to the component for processing. The service layer uses
the DmiCiInvoke() function call to do this. The C-language prototype for this
call is:
unsigned long DmiCiInvoke(PTR command)
command is the complete command block.
The return result from the component instrumentation is a 32-bit status value
indicating success or failure. The possible status values are described in
Status Codes
ΓòÉΓòÉΓòÉ 5.4. Canceling a Command ΓòÉΓòÉΓòÉ
The service layer can notify the component instrumentation of an intent to
cancel an individual command by calling the DmiCiCancel() entry point within
the component instrumentation. This can be issued as a result of a management
application issuing a DmiCancelCmd command to the service layer. The C-language
prototype for this call is:
unsigned long DmiCiCancel(void)
No parameters are needed since by definition the component instrumentation can
only be processing one command at a time.
The return result from the component instrumentation should be zero for success
and non-zero for any error. The service layer will place the result in iStatus
when sending the confirm block to the management application.
ΓòÉΓòÉΓòÉ 5.5. Registering Instrumentation ΓòÉΓòÉΓòÉ
Component instrumentation code can register with the service layer.
Registration is desirable when the component instrumentation code is already
running, such as management code associated with a running device driver.
Registering management entry points within the running code is called
registering the direct interface. The direct interface is also useful when the
time required to locate and load an executable file and set up and terminate a
process would be excessive.
Component instrumentation that has registered a direct interface causes the
service layer to override its current access mechanism for the registered
attributes. Instead of manipulating the data in the MIF database or invoking
programs, the service layer calls the entry point provided in the registration
call. When the component unregisters, the service layer returns to its usual
method of processing requests for the data, as defined in the MIF file. In
this way, component instrumentation can temporarily interrupt normal processing
to perform some special function. Note that registering attributes through the
direct interface overrides attributes that are already being served through the
direct interface.
The DmiRegisterCiInd block can be used:
To register a callable interface for components that have resident
instrumentation code
To get the version of the service layer.
For a description of the DmiRegisterCiInd block issued when registering
instrumentation, read DmiRegisterCiInd Command Block.
To unregister component instrumentation, the DmiUnregisterCiInd block is
issued to the service layer. For a description of the DmiUnregisterCiInd block
issued when unregistering instrumentation, read DmiUnregisterCiInd Command
Block.
ΓòÉΓòÉΓòÉ 5.6. Sending Events ΓòÉΓòÉΓòÉ
Component instrumentation can send unsolicited messages to the service layer to
notify it of some particular situation. These unsolicited messages are known as
events. When they reach a management application they are usually known as
indications, with an indication ID of 1. Events are often used to describe a
catastrophic occurrence or other activity that a management application should
be informed of quickly. The event identification is specific to a given
component.
The DmiIndicate() function call is provided so that component instrumentation
can send an indication block to the service layer for processing. The
C-language prototype for this call is:
unsigned long DmiIndicate(PTR command)
command is the complete command block. The return result is a 32-bit status
value indicating success or failure. The possible status values are described
in Status Codes.
While it processes the indication, the service layer immediately returns
control to the component instrumentation. The component instrumentation can
then continue processing and issue additional indications, but the
instrumentation cannot re-use the same indication buffer that it previously
sent to the service layer. Simultaneous indications from a component
instrumentation must use different indication blocks. When the service layer is
finished processing the indication, it notifies the component instrumentation
by calling the pResponseFunc() function that was given in the original
indication block. At that point, the component instrumentation can re-use the
indication block.
To send an event, the component instrumentation sends a DmiIndicate block to
the service layer's DmiIndicate() entry point. The event data is defined in a
DmiEventData block that maps onto the oIndicationData field in the DmiIndicate
block.
For a description of the DmiIndicate block used to issue an indication, read
DmiIndicate Command Block.
If you are using the DMI subagent to translate DMI indications into SNMP traps,
note the following when creating indications:
Keep the length of any strings passed in a DmiIndicate() call to 512
characters or less. Strings longer than this limit are truncated to 512
characters in the corresponding SNMP trap.
Restrict the size and number of variables associated with each DMI
indicate such that the indication will fit within the maximum SNMP frame
size supported in your network.
ΓòÉΓòÉΓòÉ 6. DMI Command Blocks ΓòÉΓòÉΓòÉ
The commands issued to the DMI by management applications and components are
composed of data structures called command blocks. A typical DMI command
contains the following:
A standard command block, such as the DmiMgmtCommand block. This block
appears first in the command block and provides a command code that
indicates the specific operation to perform and the composition of the
remainder of the command block.
One or more blocks pertaining to a specific command.
Any data associated with the command-specific blocks.
This chapter describes the command blocks used with the DMI. There are three
types of DMI command blocks:
Common command blocks
Management Interface (MI) command blocks
Component Interface (CI) command blocks
Each command block described in this chapter has the following information
presented in tabular format:
Offset Indicates the location of the element in the buffer. The offset
is the number of octets from the start of the buffer.
Size Indicates the size of the element in octets.
Type Indicates the type of element. Possible types include:
INT Integer
OFFSET Offset to another element in the block
PTR Pointer to a buffer
STRUCT Command block structure
TIMESTAMP Timestamp block
Variable name Indicates the name of the element
ΓòÉΓòÉΓòÉ 6.1. Common Command Blocks ΓòÉΓòÉΓòÉ
The DMI uses a common set of data blocks to form the basis of the commands that
are sent between management applications and component instrumentation. The
following common blocks are used as part of request blocks, response blocks,
and indication blocks:
DmiMgmtCommand
DmiCiCommand
DmiConfirm
DmiIndicate
DmiVersion
DmiGroupKeyData
DmiTimeStamp
The code samples in Management Interface (MI) Command Blocks and Component
Interface (CI) Command Blocks provide examples of how these common command
blocks can be used.
ΓòÉΓòÉΓòÉ 6.1.1. DmiMgmtCommand ΓòÉΓòÉΓòÉ
All commands issued through the MI start with a DmiMgmtCommand block. Each
outstanding command requires a separate DmiMgmtCommand block. Typically, a
command consists of the DmiMgmtCommand block, with additional parameters
appended to specify such things as the target of a request or the key data for
a table, for example.
The format for the command block is:

Variable Name Variable Description
iLevelCheck A 4-octet integer with a code value of 0x444d3131 and an
ISO 8859-1 value of DMI1. This value indicates the
revision level of the DMI specification used by the code
issuing the command and also functions as a check, so that
the receiver can be confident the pointer is pointing to a
valid command block.
iCommand A code specifying which command to execute. The standard
command codes are listed in the description of each
command.
iCmdLen Length in octets of the entire command, including the
DmiMgmtCommand block, all appended blocks, and any values
stored at the end of the buffer for Set Attribute
commands.
iMgmtHandle A value that uniquely identifies the management
application. This value is assigned to the management
application by the service layer in response to the
DmiRegisterMgmtCmd command. This value is ignored when
sending the DmiRegisterMgmtCmd command itself.
iCmdHandle Optional integer set by the management application to a
value unique to all other outstanding commands from that
management application. The handle can later be used to
cancel the command.
osLanguage Offset to a string indicating the desired human language
for the response. The format of the string is specified in
Language Statement. If the management application sets
this field to zero, the language specified by the first
MIF installed for this component is used.
oSecurity Offset to an optional security credentials block, as
defined in DmiSecurity Command Block, If no block is
specified, this value is zero. The service layer and
component instrumentation can use the information in this
block to implement local security policies.
iCnfBufLen Length of the confirm buffer, in octets of contiguous
memory. The management application sets this to inform the
service layer of the maximum size of the response.
Note: The length of the confirm buffer for
DmiListComponentCmd commands should be at least 2K to
ensure adequate space for the class strings.
pCnfBuf Pointer to the buffer where the management application
wants the confirm response to go. The management
application must supply this buffer; it is not provided by
the service layer or component instrumentation. The buffer
must be a minimum of 512 octets.
iRequestCount The number of requests in this command. This count does
not include the DmiMgmtCommand block itself.
iCnfCount Number of valid confirm blocks in pCnfBuf. This value is
set on the return of the response.
iStatus Return status of this command. In the case of an error,
where iCnfCount contains the number of valid confirms,
iStatus refers to the request represented by (iCnfCount +
1). This value is set on the return of the response.

instrumentation can issue events to the service layer. The service layer can
issue notifications of component installations and removals to management
applications. These unsolicited notifications are called indications. Each
sender of an indication fills out a DmiIndicate block. The DmiIndicate block is
then passed to the receiver's indication entry point that was obtained during
the registration process.

Variable Name Variable Description
iLevelCheck A 4-octet integer with a code value of 0x444d3131 and an
ISO 8859-1 value of DMI1. This value indicates the
revision level of the DMI specification used by the code
issuing the command and also functions as a check, so that
the receiver can be confident the pointer is pointing to a
valid indication block.
iIndicationType A code specifying the indication type. The possible codes
are:
1 Event
2 Install
3 Uninstall
4 Language map
iCmdLen Length of the entire indication block in octets.
iComponentId The ID of the component instrumentation generating this
indication.
0 The indication was generated by an entity
that has not been installed as a component
and has no component ID.
1 The service layer has initiated the
indication.
DmiTimeStamp A DmiTimeStamp block, as described in DmiTimeStamp Command
Block. If a component instrumentation initiated the
indication and set the time to zero, the service layer
adds the time stamp. If the field is non-zero, the service
layer does not check the value for accuracy.
pResponseFunc A pointer to the entry point that is called when the
receiver finishes processing the indication report.
Typically this is only for use between component
instrumentation and the service layer. The service layer
sets this field to zero before sending indications to
management applications.
Some service layer implementations might require a
response to certain indications. In this case the field is
not set to zero, and the management application must call
the service layer entry point.
oIndicationData An offset to a required buffer that provides context for
the indication. The meaning of this data is dependent on
the indication type. For events, the DmiEventData block is
returned. For component installs and removals, a
DmiListComponentCnf block is returned.
ΓòÉΓòÉΓòÉ 6.1.5. DmiVersion ΓòÉΓòÉΓòÉ
This block describes the version of the service layer implementation. It is
returned by the registration calls DmiRegisterMgmtCmd and DmiRegisterCiCmd.

This block defines a key to be used when indexing into a group that is arranged
as a table. The number of DmiGroupKeyData blocks must match the number of
integers specified in the key statement of the component definition. For
example, if the key statement identifies attributes 4, 7, and 3 as indexes,
there must be three DmiGroupKeyData blocks, with the first corresponding to
attribute 4, the next corresponding to attribute 7, and the last corresponding
to attribute 3.
Out-of-order keys and partial keys are not supported. A key must uniquely
identify no more than one instance of a table.

Variable Name Variable Description
DmiMgmtCommand The command block. The value of iCommand is 0x100.
pConfirmFunc Pointer to a routine in the management application that
the service layer calls after completing each command. The
C prototype for this call is:
void pConfirmFunc(PTR cmd)
The variable cmd points to the command block that has
completed. If pConfirmFunc() is set to zero, the
management application cannot use DmiInvoke to issue
management directives but can still receive indications,
if pIndicationFunc() is non-zero.
pIndicationFunc Pointer to a routine in the management application that
the service layer calls to send unsolicited reports,
either because of an event or because a component has been
removed. If the management application does not want to
receive indications, it must set this field to zero. The C
prototype for this call is:
void pIndicationFunc(DmiIndicate *buf)
The variable buf points to a DmiIndicate block.
Issuing DmiRegisterMgmtReq displays an example of how to issue the
DmiRegisterMgmtReq command block to the MI.

Variable Name Variable Description
DmiMgmtCommand The command block. The values of iCommand indicate the
command:
DmiListComponentCmd 0x200
DmiListFirstComponentCmd 0x201
DmiListNextComponentCmd 0x202
iComponentId Component ID for the desired component. This field is
ignored for DmiListFirstComponentCmd. For
DmiListNextComponentCmd, the service layer starts filling
the confirm buffer beginning with the component ID that
follows the value in this field. To start at the first
component, set this field to zero. On return from the
command, the service layer updates this field with the ID
of the last component in the confirm buffer. The
management application can continue issuing
DmiListNextComponentCmd commands until the returned
iStatus field indicates that there is no more data.
osClassString Offset to a string that acts as a filter to retrieve data
for components that have groups with specific class
strings. If a field of the class string is not
significant, it can be omitted.
For example, if an application is looking for all
component ID groups, it uses the string
"DMTF|ComponentID|". Because the version string is
missing, the service layer considers any version a match,
as long as the first two fields match. If no filtering is
desired, set this field to zero or to an empty class
string ("||").
iGroupKeyCount The number of elements of type DmiGroupKeyData pointed to
by oGroupKeyList. If any keys are given, they are used
with the group class for filtering, and the service layer
returns a list of the components that have a particular
row in a particular table. It is an error to specify keys
without specifying a class string.
oGroupKeyList Offset to a list of blocks of type DmiGroupKeyData.
Issuing DmiListComponentReq displays an example of how to issue the
DmiListComponentReq command to the MI.

ΓòÉΓòÉΓòÉ 6.2.4. DmiListComponentCnf ΓòÉΓòÉΓòÉ
On return from the DmiListComponentReq call, the confirm buffer contains an
array of one or more DmiListComponentCnf blocks. The value of iCnfCount in the
DmiMgmtCommand block is set to the number of DmiListComponentCnf blocks
returned from this call. The value of iStatus indicates whether there was more
data than would fit in the confirm buffer. If so, the service layer updates
iComponentId in the command buffer, so the management application can re-issue
the command and resume getting data from the point where it stopped.
The format of DmiListComponentCnf is:

DmiMgmtCommand The command block. The values of iCommand are:
DmiListGroupCmd 0x204
DmiListFirstGroupCmd 0x205
DmiListNextGroupCmd 0x206
iComponentId ID of the desired component.
iGroupId ID of the desired group within the component identified by
iComponentId. In DmiListFirstGroupCmd, this field is
ignored. For the DmiListNextGroupCmd command, the service
layer starts filling confirm buffer beginning with the
group ID that follows the value in this field. To start at
the first group, set this field to zero. On return from
the command, the service layer updates this field with the
ID of the last group put in the confirm buffer. The
management application can continue issuing
DmiListNextGroupCmd commands until the returned iStatus
field indicates that there is no more data.

On return from the DmiListGroupReq call, the confirm buffer contains an array
of one or more DmiListGroupCnf blocks. iCnfCount in the DmiMgmtCommand block is
set to the number of DmiListGroupCnf blocks returned from this call. iStatus
indicates whether there was too much data than would fit in the confirm buffer.
In this case, the service layer updates iGroupId in the command buffer so the
management application can re-issue the command to continue getting data from
where it left off.

Variable Name Variable Description
DmiMgmtCommand The command block. The values of iCommand are:
DmiListAttributeCmd 0x208
DmiListFirstAttributeCmd 0x209
DmiListNextAttributeCmd 0x20a
iComponentId The ID of the desired component.
iGroupId The ID of the desired group within the component
identified by iComponentId.
iAttributeId The ID of the desired attribute within the group. In
DmiListFirstAttributeCmd, this field is ignored. For the
DmiListNextAttributeCmd command, the service layer starts
filling the confirm buffer beginning with the attribute ID
that follows the value in this field. To start at the
first attribute, set this field to zero. On return from
the command, the service layer updates this field with the
ID of the last attribute put in the confirm buffer. The
management application can continue issuing
DmiListNextAttributeCmd commands until the returned
iStatus field indicates that there is no more data.
Issuing DmiListAttributeReq displays an example of how to issue the
DmiListAttributeReq command to the MI.

On return from the DmiListAttributeReq call, the confirm buffer contains an
array of one or more DmiListAttributeCnf blocks. iCnfCount in the
DmiMgmtCommand block is set to the number of DmiListAttributeCnf blocks
returned from this call. iStatus indicates whether there was too much data than
would fit in the confirm buffer. In this case, the service layer updates
iAttributeId in the command buffer so the management application can re-issue
the command to continue getting data from where it left off.
The format of the DmiListAttributeCnf block is:

DmiMgmtCommand The command block. The values of iCommand are:
DmiListComponentDescCmd 0x203
DmiListGroupDescCmd 0x207
DmiListAttributeDescCmd 0x20b
iComponentId The ID of the desired component.
iGroupId The ID of the desired group within the component
identified by iComponentId. This field is ignored when
listing component descriptions.
iAttributeId The ID of the desired attribute within the group. This
field is only required for getting attribute descriptions.
Otherwise, it is ignored.
iOffset Number of characters into the description where the
service layer should start getting the description string.
Use zero to start at the beginning of the description.
On return, the service layer updates this field with the
index of the last character written into the confirm
buffer and sets iStatus accordingly. If iStatus indicates
that there are more characters to be received, the
application can re-issue the call to get more of the
description text.
On return from this call, the confirm buffer contains the text from the
description associated with the entity requested. In the command block,
iCnfCount is always set to 1.

DmiMgmtCommand The command block. The values of iCommand are:
DmiGetRowCmd 0x304
DmiGetFirstRowCmd 0x305
DmiGetNextRowCmd 0x306
iComponentId The ID of the desired component.
iGroupId The ID of the desired group.
iGroupKeyCount The number of DmiGroupKeyData blocks pointed to by
oGroupKeyList.
oGroupKeyList Offset to a list of DmiGroupKeyData blocks. iGroupKeyCount
is the number of blocks in the list.
iAttributeId The attribute ID just before the attribute ID where the
Get Row command should start. Use zero to start at the
first attribute in the group. This is generally used when
the confirm buffer is too small and the service layer has
more information than will fit in the buffer. Upon return,
the service layer updates this field with the last
attribute returned and sets iStatus to 1 to indicate that
there is more information than the confirm buffer could
hold.

Variable Name Variable Description
iGroupId The ID of the group.
iGroupKeyCount The number of DmiGroupKeyData blocks pointed to by
oGroupKeyList.
oGroupKeyList Offset to a list of DmiGroupKeyData blocks.
iGroupKeyCount is the number of blocks in the list.
iAttributeCount The number of DmiGetAttributeCnf blocks immediately
following this block.
DmiGetAttributeCnf[] The list of DmiGetAttributeCnf blocks.
In the case where the size of a group exceeds the size of the calling
application's confirm buffer, the calling application receives a status of 1,
indicating that the command was successful but that there is more of the group
to be retrieved. In this case, the command can be re-issued to retrieve the
rest of the group. To do this, the calling application sets the iAttributeId
field to the value of the last attribute returned in the previous Get Row
command. The component instrumentation then returns the attribute values that
follow this attribute.
Processing DmiGetRowCnf for DmiGetFirstRowCmd and DmiGetNextRowCmd displays an
example of how to handle the DmiGetRowCnf callback command block in response
to the DmiGetFirstRowCmd and DmiGetNextRowCmd commands. For this example, all
callbacks that are returned to the management application are processed
through a single entry point.

DmiVersion A block defining the version of the service layer.
iDmiHandle Set to a unique handle for this component instrumentation.
This is only valid for as long as the component
instrumentation is registered with the service layer. The
handle is passed to the service layer when unregistering.
A component can register more than once. This is necessary when a component
has multiple entry points for instrumentation. In this case, the component
instrumentation is assigned multiple handles.

are returned to the management application are processed through a single

ΓòÉΓòÉΓòÉ 7. Enabling a Product for the DMI ΓòÉΓòÉΓòÉ
This chapter describes how to enable a product to be managed as a component
through the DMI.
The general tasks to enable a product include:
Defining which aspects of the product are to be managed
Writing a Management Information Format (MIF) file to describe the
manageable features
Writing instrumentation code to provide the service layer with
information about the component
Determining what errors, exceptions, or problems are to be forwarded to
the service layer as indications
Installing the MIF into the MIF database
ΓòÉΓòÉΓòÉ 7.1. Defining the Product's MIF File ΓòÉΓòÉΓòÉ
A MIF file is an ASCII text file that conforms to the Management Information
Format (MIF) described in the DMI Specification. The MIF file for a component
defines the manageable aspects of the component and provides this information
to management applications through the DMI. Because the DMI does not assume
that a management application can determine anything about a component in the
system, it is important that the component provide all significant information
about its manageable characteristics through the MIF file.
The steps involved for defining a MIF file include:
Determining what characteristics of the component can be managed
Defining the groups into which these characteristics will be organized
Defining the attributes that make up the groups
A MIF file can contain as few as one group with the six standard attributes or
as many groups and attributes as you choose.
ΓòÉΓòÉΓòÉ 7.1.1. Determining Attributes ΓòÉΓòÉΓòÉ
Before you begin determining possible grouping arrangements for the attributes
in your component, be sure that you have considered all of the manageable
aspects of your component in as much detail as possible. Be sure to include all
of the items that can be configured or that can be changed, as well as
information that enables asset management, such as a product version number or
a serial number.
The ComponentID group (ComponentID Group) is a good example of these kinds of
attributes.
You can also examine existing MIF files of other components to get an idea of
what kinds of attributes are defined to enable a product for management through
the DMI.
ΓòÉΓòÉΓòÉ 7.1.2. Defining Groups ΓòÉΓòÉΓòÉ
After you have determined all of the attributes that apply to your component,
you must define the groups into which these attributes will be organized. When
you are defining the groups and attributes for the component, consider how the
component will be used. The groups you define should be conceptually distinct
from each other and should pertain to a manageable aspect of your component,
whether that is a physical or logical element of the component.
If your component is a software product, you might want to define your groups
according to the functions a user can perform with the product. A
word-processing program, for example, might require groups that describe the
editing function, the spell-checker, the drawing tools, and the printing
function.
If your component is a hardware product, such as a LAN adapter card, you might
want to relate your groups more closely to the physical aspects of the device.
In the case of a LAN adapter card, the defined groups could describe such
things as the port adapter statistics, the adapter hardware, and the
operational state of the adapter.
Keep the following points in mind when defining your component's groups:
Whenever possible, use the standard MIF files and groups specified by the
DMTF, instead of creating private, non-standard groups. Using these
common groups allows more management applications to manage your
component. The standard groups that are available are defined in the
following standard MIF files maintained by the DMTF:
- Network Interface Card (NIC) MIF
- Desktop System MIF
- Large Mailroom Operation (LMO) MIF
- Printer MIF
- Software MIF
Note: When you use a standard group, change only the attribute value for
any attributes in the group. For those attributes that you do not use,
specify the Unsupported keyword for the value. Do not change any other
items in the standard attributes, such as attribute ID or attribute type,
and do not renumber the attributes within a standard group.
Consult existing proprietary MIF files or groups for ideas about how to
model difficult aspects of your component. You might find that another
component's MIF file has addressed a similar problem.
Keep the number of attributes in a group to 20 or fewer, if possible.
Small groups are easier to manage, and their modular design makes them
easier for you to reuse than a few large groups. Even only one or two
attributes in a group is reasonable, as long as the grouping is still
logical.
Define your groups to be reusable. Although you are creating a MIF file
for a single component, you might be able to use the defined groups in
MIF files for other components you design.
Allow for different views of the same data by providing both standard
public groups of attributes and private, individual groups of attributes.
For instance, both the external fax-modem and the internal built-in modem
can be described by the modem group, but each would need an individual
group to describe characteristics that do not apply in the standard
group.
ΓòÉΓòÉΓòÉ 7.2. Defining Attributes ΓòÉΓòÉΓòÉ
After you determine the manageable aspects of your component and define the
groups you will use to organize the attributes, you are ready to define the
attributes according to the MIF. Understanding the MIF provides a detailed
description of the syntax and conventions used by the MIF, including the
different definitions used to define your MIF file.
The attribute is the smallest piece of your component that can be defined and
identifies a discrete manageable aspect of the component. The way you define an
attribute affects not only how the attribute value is stored and accessed but
also how the component is managed. To ensure that management of your component
is as efficient as possible, consider these points when defining the attributes
in your component:
Access to an attribute should be determined by the likelihood of its
changing. If it is clear that an attribute value will not change or
should not be modified, define the attribute with read-only access.
For those attributes that do change, determine whether the value should
be available to a management application. If so, read-write access is
appropriate for the attribute, but if not, specify write-only access for
the attribute.
Tables provide flexibility for defining and managing attributes that
require more than one value. As your component develops, the tables you
have defined can be expanded to accommodate any changes.
When defining key attributes to be used as indexes into a table, use as
many keys as necessary to provide management applications efficient and
flexible access to the data in the table. The attributes you specify as
keys should be appropriate to the component and not simply arbitrary
indexing values.
If you are developing a component that does not have instrumentation
associated with it, ensure that the order of the keys in the MIF file is
sequential. This maximizes performance of the service layer, particularly
across SNMP.
Note: The values for each row in a table, including the key value, must
be supplied either from the MIF database or by component instrumentation.
You cannot supply values from the database and from instrumentation for
the same row.
Do not add attributes specific to your component to those defined for a
standard group. If you alter the contents of a standard group, management
applications can no longer manage the group reliably. Instead, use the
standard group in your component and add another group that contains your
private attribute definitions.
Use detailed description statements to provide as much information about
your attributes as possible. Information such as minimum, maximum, and
default values is also useful.
Designate how an attribute value is to be supplied according to the
stability and nature of the attribute. If the attribute value is static,
the value can be supplied by the MIF database. However, if the attribute
value is likely to change frequently, specify that the value be supplied
by component instrumentation, such as a runtime program or a
direct-interface program. This ensures that the value provided for an
attribute is current.
For example, ProductID and SerialNumber are likely candidates for
database attributes because their values are not likely to change.
However, Available_Bytes_on_Hard_Drive is an attribute that is
appropriate for component instrumentation.
ΓòÉΓòÉΓòÉ 7.3. Writing the MIF File ΓòÉΓòÉΓòÉ
You can write the MIF file with any editor you choose, as long as it is a plain
ASCII text file with no embedded formatting commands or control characters.
Although the order of group definitions in the MIF file does not affect the way
the file is interpreted by the service layer, the structure of the MIF file
should be logical and organized for easy maintenance and expansion. Use white
space, indentation, and comments to enhance the readability of the file.
The conventions and syntax used by the Management Information Format are
described in detail in Understanding the MIF.
Follow these general steps when writing the MIF file:
Define your groups and specify which are standard and which are private
to the component. Use the ComponentID group as the first group in the
file.
If a group functions as a table template, specify a key value and an ID,
if appropriate.
Define any enumeration definitions that apply to the component as a
whole.
Define the attributes for each group.
Define any table definitions that refer to previously defined templates,
if appropriate.
ΓòÉΓòÉΓòÉ 7.4. Writing Instrumentation Code ΓòÉΓòÉΓòÉ
When a component receives a request from the service layer for an attribute's
value, the instrumentation code for the component is invoked to retrieve the
value. By providing instrumentation for your component, you ensure that the
information that is accessed by management applications is both current and
accurate. Without instrumentation, you run the risk of allowing the information
in the MIF file to become outdated.
You can provide instrumentation for your component in one of two ways:
An overlay program
A direct-interface program
ΓòÉΓòÉΓòÉ 7.4.1. Overlay Programs ΓòÉΓòÉΓòÉ
An overlay program is invoked by the service layer whenever a management
application requests to retrieve or set the value of an attribute in the
component. The overlay program is loaded into the service layer's process space
and enables the service layer to directly access the attribute values through
the overlay program's procedures. When the request is completed, the service
layer unloads the overlay program.
Overlay programs are useful for components that do not already have resident
code or for components running in systems with constrained memory. They are
also appropriate if they are called infrequently. The data associated with your
component is not retained by the overlay program between invocations, unless
you specifically designate some storage mechanism for the values. If your
component data must always be available, a direct-interface program is more
appropriate.
ΓòÉΓòÉΓòÉ 7.4.2. Direct-interface Programs ΓòÉΓòÉΓòÉ
A direct-interface program runs continuously as a separate process in the
system. As part of its initialization, the program registers with the service
layer and indicates the component with which the program is associated. When
the service layer receives requests from management applications for
information in that component, the service layer passes the request over to the
direct-interface program, which returns the appropriate values.
An advantage of the direct-interface program is its ability to maintain
up-to-date component information. Because the program is always running, the
attribute values for the component are always current and are not discarded
between requests. The code for a direct-interface program can be added to the
device driver code for the component (if appropriate) or to any other program
that is loaded in the background.
A disadvantage of the direct-interface program is that it is always loaded and
utilizing resources.
ΓòÉΓòÉΓòÉ 7.4.3. Coding Considerations ΓòÉΓòÉΓòÉ
Instrumentation code, whether for an overlay program or a direct-interface
program, must be designed to process the following DMI commands:
DmiGetAttributeCmd
DmiSetAttributeCmd
DmiSetReserveAttributeCmd
DmiSetReleaseAttributeCmd
DmiGetRowCmd
DmiGetFirstRowCmd
DmiGetNextRowCmd
These commands are all accessed through the DmiCiInvoke function call, which
is sent from the service layer. In addition to these commands, the
instrumentation code must also issue the pConfirmFunc function call for every
command, including set commands and commands that generate errors.
For the DmiGetFirstRowCmd and DmiGetNextRowCmd commands, the DmiGetRowCnf
structure is generated by the service layer before it issues the DmiCiInvoke
function call. The GroupKeyData structures are also allocated, and the
oGroupKeyList variable in the DmiGetRowCnf structure is supplied. Your
instrumentation code can only modify the confirm buffer and not the DmiInvoke
command buffer.
For a complete description of the commands and structures used by the DMI,
read DMI Command Blocks
The SystemView Agent program also includes the DMI procedures library (DMIAPI)
to simplify the writing of instrumentation code. By using the procedures
provided by the DMI API and by patterning your code after the sample programs
included in the SystemView Agent, many considerations regarding function calls
and DMI commands are resolved for you. For a detailed explanation of the DMI
procedures library, read DMI Procedure Library (DMIAPI).
ΓòÉΓòÉΓòÉ 7.4.3.1. Overlay Programs ΓòÉΓòÉΓòÉ
To enable the service layer to properly access the overlay program for your
component, ensure that you do the following when writing your MIF file:
Specify the name of the component instrumentation as part of the path
definition for your component. For example:
start paths
name = "EXPOverlay"
os2 = "names"
unix = "/usr/lpp/sva/bin/names"
end paths
In this case, the value of the name statement is used in attribute
definitions to refer back to this path definition. The operating system
statement identifies the filename of an OS/2 dynamic link library (DLL)
that functions as the overlay program.
In the definition for any attribute that requires instrumentation to
provide its value, specify the path definition. For example, in the
attribute definition use the following statement:
value = * "EXPOverlay"
This identifies the previous path definition by its name statement and
enables the service layer to load the proper overlay program to retrieve
the attribute's value.

SystemView Agent:

ΓòÉΓòÉΓòÉ 7.4.3.2. Direct-interface programs ΓòÉΓòÉΓòÉ
To use a direct-interface program to retrieve attribute values, your component
must register with the service layer as a direct-interface component. When it
registers, the component passes its entry point to the service layer. This
enables the service layer to pass control to the direct-interface program when
an attribute's value is required. When the direct-interface program unloads, it
unregisters with the service layer.
You can indicate that your component relies on a direct-interface program by
using the direct-interface keyword in the path definition of the component's
MIF file. For example:
start paths
name = "NAMES - Direct Interface"
os2 = direct-interface
unix = direct-interface
end paths
This ensures that the service layer can return an appropriate error if it
attempts to access the value for an attribute and the direct-interface program
is not running.

ΓòÉΓòÉΓòÉ 7.5. Sending Events ΓòÉΓòÉΓòÉ
When a component encounters an error situation or needs to notify a management
application of a status change, for example, the component sends an event to
the service layer. If a management application has requested to receive
unsolicited notifications from that component, the service layer forwards the
event to the management application as an indication.
You can use events to enhance the manageability of your component by providing
detailed information about the status of the component and by notifying
management applications of these changes in a timely manner. Events are
especially useful when a serious error or similar change has occurred and the
management application must be informed immediately.
Events are issued with the DmiIndicate function call. The service layer
processes the events as they are received and returns a status value indicating
the success or failure of the DmiIndicate call. For more information about the
DmiIndicate call and its associated command blocks, read DmiIndicate Command
Block.
ΓòÉΓòÉΓòÉ 7.6. Installing Components ΓòÉΓòÉΓòÉ
When you install your component on a system, the installation procedure either
incorporates the MIF file for the component into the MIF database or, if the
service layer is not running, installs the file in the MIF subdirectory. To
accomplish this, you can use the DmiInstall procedure that is included in the
DMI procedure library. This procedure handles such tasks as adding the MIF file
to the MIF database and determining whether the service layer is running.
For a detailed explanation of the DMI procedures library, read DMI Procedure
Library (DMIAPI).

ΓòÉΓòÉΓòÉ 7.7. Uninstalling Components ΓòÉΓòÉΓòÉ
The uninstall procedure for your component should do the following:
If the component uses a direct-interface program, ensure that the program
issue a DmiCiUnregister command, if the program is registered to the
service layer and currently running,
Remove the MIF file for the component from the MIF database by issuing a
DmiCiUninstall command.
To issue this command, your uninstall procedure must identify which
component ID in the MIF database corresponds to your component.
ΓòÉΓòÉΓòÉ 8. DMI Procedure Library (DMIAPI) ΓòÉΓòÉΓòÉ
The DMI procedure library provided with the SystemView Agent package is a C
library that contains procedures for a specific operation system for developing
applications that use the DMI Management Interface and Component Interface
entry points. You can use the procedures in the library to simplify the
processes of installing components in the MIF database and invoking the service
layer's Component Interface. The procedures in the DMI procedure library are
used in the example programs provided with the SystemView Agent program.

ΓòÉΓòÉΓòÉ 8.2. Procedures and Data Types ΓòÉΓòÉΓòÉ
This section describes the procedures and data types that make up the DMI
procedure library. The procedures include:
DmiCiProcess()
DmiInstall()
DmiInvoke()
DmiIndicate()
ΓòÉΓòÉΓòÉ 8.2.1. DmiCiProcess() ΓòÉΓòÉΓòÉ
This procedure is called by DmiCiInvoke(). It processes a command through the
service layer's Component Interface.
ΓòÉΓòÉΓòÉ 8.2.1.1. Syntax ΓòÉΓòÉΓòÉ
DMI_UNSIGNED DMI_FUNC_ENTRY DmiCiProcess (DmiCiControl_t *Command,
void _FAR*dmiCommand);
ΓòÉΓòÉΓòÉ 8.2.1.2. Parameters ΓòÉΓòÉΓòÉ
Command A pointer to the current Component Interface command block.
dmiCommand A pointer to the current command block passed by the service
layer to the program through DmiCiInvoke.
ΓòÉΓòÉΓòÉ 8.2.2. DmiInstall() ΓòÉΓòÉΓòÉ
This procedure allows an application developer writing a product setup or
installation program to easily add MIF files to the MIF database.
ΓòÉΓòÉΓòÉ 8.2.2.1. Syntax ΓòÉΓòÉΓòÉ
DmiLibInstallData_t *DMI_FUNC_ENTRYDmiInstall( int iFileCount,
DmiLibFileData_t *dmiLibFileList,
DMI_STRING *pDmiDir,
int iDefineDmiDir
int StatusCall);
ΓòÉΓòÉΓòÉ 8.2.2.2. Parameters ΓòÉΓòÉΓòÉ
iFileCount The number of files within the dmiFileList structure.
dmiLibFileList An array of structures containing the types and locations of
the files to install.
pDmiDir A DMI_STRING pointer to an operating system definition for the
DMIDIR environment variable. If this field is NIL, the library
uses the system definition. When this field is specified, the
library uses this path name in place of the system definition.
This parameter is ignored by the OS/2 implementation.
iDefineDmiDir A Boolean value (for which non-zero is true) that directs the
library to modify the system startup file to include a
definition for the DMIDIR environment variable.
If pDmiDir is not NIL, DMIAPI.LIB uses the value of that field
in the modified system startup file.
If pDmiDir is NIL, DMIAPI.LIB uses the current value of the
DMIDIR environment variable. If DMIDIR is not defined,
DMIAPI.LIB attempts to query the service layer for the path
name of the DMI directory. If DMIAPI.LIB is unable to determine
the path name of the DMI directory, DmiInstall() terminates
with an error. To resolve this condition, the calling program
must re-issue the DmiInstall() command, with the pDmiDir
parameter defined.
If the system startup file already had a definition for DMIDIR,
then that definition will be removed, and the new definition
will be added.
This parameter is ignored by the OS/2 implementation.
StatusCall A callback entry point that the service layer calls with the
MIF compiler messages.
The Component Installation Status window in the DMI browser is
an example of how you can use this parameter to display
messages.
ΓòÉΓòÉΓòÉ 8.2.3. DmiInvoke() ΓòÉΓòÉΓòÉ
The DMI Specification describes the MI entry point of the service layer. The
entry point is called DmiInvoke(). The DmiInvoke() procedure is used by the
calling application to issue commands to the service layer.
ΓòÉΓòÉΓòÉ 8.2.3.1. Syntax ΓòÉΓòÉΓòÉ
DMI_UNSIGNED DMI_FUNC_ENTRY DmiInvoke(void _FAR *dmiMgmtCommand);
ΓòÉΓòÉΓòÉ 8.2.3.2. Parameters ΓòÉΓòÉΓòÉ
dmiMgmtCommand A pointer to a DMI command
ΓòÉΓòÉΓòÉ 8.2.3.3. Notes ΓòÉΓòÉΓòÉ
If the service layer is not running, an SLERR_SL_INACTIVE error is returned.
Otherwise the return value from DmiInvoke() is the value returned by the
service layer when the command was issued. Error codes are documented in Status
Codes
ΓòÉΓòÉΓòÉ 8.2.4. DmiIndicate() ΓòÉΓòÉΓòÉ
This procedure operates like DmiInvoke but is the indication entry point of the
service layer.
ΓòÉΓòÉΓòÉ 8.2.4.1. Syntax ΓòÉΓòÉΓòÉ
DMI_UNSIGNED DMI_FUNC_ENTRY DmiIndicate(DMI_Indicate_t _FAR
*dmiIndication);
ΓòÉΓòÉΓòÉ 8.2.4.2. Parameters ΓòÉΓòÉΓòÉ
dmiIndication A pointer to a DMI indication block.
ΓòÉΓòÉΓòÉ 8.2.4.3. Notes ΓòÉΓòÉΓòÉ
If the service layer is not running, an SLERR_SL_INACTIVE error is returned.
ΓòÉΓòÉΓòÉ 8.2.5. Data Types ΓòÉΓòÉΓòÉ
The data types used by the procedures in the DMI procedure library are
described in this section. For each data type, the syntax is given and the
parameters are explained.
ΓòÉΓòÉΓòÉ 8.2.5.1. DMI_STRING ΓòÉΓòÉΓòÉ
The syntax for using DMI_STRING is:
typedef struct {
unsigned long length;
char body[1];
} DMI_STRING;
Parameter Description
length The length of the string
body The data for the string. The string is not null-terminated.
The 1 in the definition is strictly for ANSI C compliance. The
actual size will be the size of the string.
ΓòÉΓòÉΓòÉ 8.2.5.2. DmiLibBoolean ΓòÉΓòÉΓòÉ
The syntax for using DmiLibBoolean is:
typedef enum {DmiLibFalse, DmiLibTrue} DmiLibBoolean_t;
DmiLibFalse 0
DmiLibTrue 1
ΓòÉΓòÉΓòÉ 8.2.5.3. DmiLibFileType ΓòÉΓòÉΓòÉ
The syntax for using DmiLibFileType is:
typedef enum {MifFileName = 2, MifFilePointer} DmiLibFileType_t;
MifFileName 2
MifFilePointer 3
ΓòÉΓòÉΓòÉ 8.2.5.4. DmiLibFileData ΓòÉΓòÉΓòÉ
The syntax for using DmiLibFileData is:
typedef struct {
unsigned long iFileType;
DMI_STRING *pFileData;
} DmiLibFileData_t;
Parameter Description
iFileType The type of the referenced file:
1 MIF file name
2 MIF file pointer
pFileData A DMI_STRING pointer to the file data. For type 2, this pointer
references the operating system path name to the file. For type 3,
the pointer references a DMI_STRING object that contains the
actual file data.
ΓòÉΓòÉΓòÉ 8.2.5.5. DmiLibInstallData ΓòÉΓòÉΓòÉ
A pointer to this structure is used as the return value from calling
DmiInstall(). The syntax for using DmiLibInstallData is:
typedef struct {
unsigned long iComponentId;
unsigned long iDmiLibStatus;
unsigned long iSlStatus;
} DmiLibInstallData_t;
Parameter Description
iComponentId The component ID that the service layer assigned to the newly
installed MIF file.

ΓòÉΓòÉΓòÉ 9.3. Implementation Considerations for OS/2 ΓòÉΓòÉΓòÉ
This section describes characteristics of the service layer that you need to be
aware of when developing applications and instrumentation in an OS/2
environment.
ΓòÉΓòÉΓòÉ 9.3.1. 16-Bit to 32-Bit Thunking ΓòÉΓòÉΓòÉ
The service layer is a 32-bit application. If you are developing component
instrumentation or a management application that is a 16-bit application,
ensure that your application supports 16-bit to 32-bit thunking.
ΓòÉΓòÉΓòÉ 9.3.2. Callback Threading ΓòÉΓòÉΓòÉ
The confirm callback that the service layer returns to an application is sent
on a separate thread from that used by the application's executable file. The
application can post a message directly on the callback.
Ensure that your application does not block the callback thread.
ΓòÉΓòÉΓòÉ 9.3.3. Synchronous and Asynchronous Components ΓòÉΓòÉΓòÉ
The example components NAMES and NAMEDIR are both designed to respond to
requests in a synchronous manner. The component processes each request as it is
received and does not process subsequent requests until the previous request
has been answered.
You can take a synchronous component and modify it to function asynchronously
by doing the following:
Create a thread that is blocked until a command is received from a
management application.
When the command is received, the component instrumentation queues the
command to the waiting thread and returns from the DmiCiInvoke() function
call immediately. The service layer continues operation and does not call
the component again until the first command has completed.
The thread processes the command just as it would in a synchronous
situation, but after the thread issues the callback to the service layer,
it returns to the blocked state or terminates.
This enables the service layer to process other requests.
ΓòÉΓòÉΓòÉ 9.3.4. Debugging Overlay Instrumentation ΓòÉΓòÉΓòÉ
Overlay component instrumentation can be difficult to debug because of its
transitory nature. To facilitate this kind of debugging, you can use a debug
option when running the service layer.
Before you use this option, you must stop the service layer, if it's already
running. If you start the service layer automatically when your system starts,
do the following:
Comment out the RUN= line in your CONFIG.SYS file that starts the
DMISL.EXE program.
Restart your system.
To start the service layer with the debug option, enter the following command
from an OS/2 command prompt:
DMISL DEBUG
If the subdirectory containing the service layer executable file is not in
your PATH statement, enter the appropriate drive and path as part of the
command.
When the service layer is loaded, a debug address is displayed. When you set a
breakpoint at this address, execution stops just before the DmiCiInvoke()
function call is issued. At this point the overlay component DLL is already
loaded, and you can specify breakpoints in the instrumentation wherever you
need them.
ΓòÉΓòÉΓòÉ 9.3.5. Service Layer Time-out ΓòÉΓòÉΓòÉ
If the OS/2 service layer provided with SystemView Agent issues a request to a
component and the component takes longer than 15 seconds to respond, the
service layer automatically deregisters the component. The service layer then
terminates any other outstanding requests to the component. Further requests
sent to the component yield an error (RC=1003; CPERR_CI_TERMINATED).
The DMI browser continues to display the component icon until the component is
deinstalled. If you attempt to expand the icon after the time-out has occurred,
the DMI browser returns an error.
ΓòÉΓòÉΓòÉ 10. Implementing DMI on AIX ΓòÉΓòÉΓòÉ
This chapter describes the AIX files provided with the SystemView Agent program
for use in creating applications and component instrumentation in an AIX
environment. The following types of files are included:
Program files related to the service layer
Example files for an AIX management application and component, including
overlay and direct-interface instrumentation for the component
The chapter also presents any implementation considerations that are specific
to AIX.
ΓòÉΓòÉΓòÉ 10.1. Program Files ΓòÉΓòÉΓòÉ
AIX Program Files displays a list of AIX program files provided with the
SystemView Agent program. The subdirectory indicating a file's location is the
default subdirectory used during installation. If you installed SystemView
Agent in a different directory, adjust the file location accordingly.

ΓòÉΓòÉΓòÉ 10.3. Implementation Considerations for AIX ΓòÉΓòÉΓòÉ
This section describes characteristics of the service layer that you need to be
aware of when developing applications and instrumentation in an AIX
environment.
ΓòÉΓòÉΓòÉ 10.3.1. Synchronous and Asynchronous Components ΓòÉΓòÉΓòÉ
The example components NAMES and NAMEDIR are both designed to respond to
requests in a synchronous manner. The component processes each request as it is
received and does not process subsequent requests until the previous request
has been answered.
You can take a synchronous component and modify it to function asynchronously
by doing the following:
Create a thread that is blocked until a command is received from a
management application.
When the command is received, the component instrumentation queues the
command to the waiting thread and returns from the DmiCiInvoke() function
call immediately. The service layer continues operation and does not call
the component again until the first command has completed.
The thread processes the command just as it would in a synchronous
situation, but after the thread issues the callback to the service layer,
it returns to the blocked state or terminates.
This enables the service layer to process other requests.
ΓòÉΓòÉΓòÉ 10.3.2. Service Layer Time-out ΓòÉΓòÉΓòÉ
If the AIX service layer provided with SystemView Agent issues a request to a
component and the component takes longer than 15 seconds to respond, the
service layer automatically deregisters the component. The service layer then
terminates any other outstanding requests to the component. Further requests
sent to the component yield an error (RC=1003; CPERR_CI_TERMINATED).
The DMI browser continues to display the component icon until the component is
deinstalled. If you attempt to expand the icon after the time-out has occurred,
the DMI browser returns an error.
ΓòÉΓòÉΓòÉ 10.3.3. Compiling Overlay Components ΓòÉΓòÉΓòÉ
If you are developing an overlay component in AIX, use the -e DmiCiEntryPoint
option when linking the program. This flag changes the entry point of the
component from "main" to "DmiCiEntryPoint". DmiCiEntryPoint is a function that
provides the service layer with the function addresses of DmiCiInvoke() and
DmiCiCancel(). The service layer needs these addresses to communicate with the
overlay component and requires DmiCiEntryPoint to be the entry point of the
overlay component because of programming considerations in AIX.
The following example indicates how these flags can be used in an AIX makefile:
names: names.o Makefile $(SLLIBS)
$(CCC) -o $@ -e DmiCiEntryPoint names.o $(LINKLIBDIR) $(LIBS)
ΓòÉΓòÉΓòÉ 10.3.4. Security Considerations with Overlay Components ΓòÉΓòÉΓòÉ
Because overlay component instrumentation code runs as part of the service
layer and is executed with root privileges, these components must be installed
in the /usr/lpp/sva/overlay directory. You must have root privileges to write
to this directory.
Changing the privileges of the /usr/lpp/sva/overlay directory could allow a
non-root user to install a component that would then run with root privileges,
creating a potential security exposure. For this reason, it is important that
you ensure that the /usr/lpp/sva/overlay directory is only writeable by those

ΓòÉΓòÉΓòÉ 11. Implementing DMI on Windows NT/Windows 95 ΓòÉΓòÉΓòÉ
This chapter describes the Win32 files provided with the SystemView Agent
program for use in creating applications and component instrumentation in a
Windows NT or Windows 95 environment. The following types of files are
included:
Program files related to the service layer

ΓòÉΓòÉΓòÉ 11.3. Implementation Considerations for Windows NT/Windows 95 ΓòÉΓòÉΓòÉ
This section describes characteristics of the service layer that you need to be
aware of when developing applications and instrumentation in a Windows
NT/Windows 95 environment.
ΓòÉΓòÉΓòÉ 11.3.1. 16-Bit to 32-Bit Thunking ΓòÉΓòÉΓòÉ
The service layer is a 32-bit application. If you are developing component
instrumentation or a management application that is a 16-bit application,
ensure that your application supports 16-bit to 32-bit thunking.
ΓòÉΓòÉΓòÉ 11.3.2. Callback Threading ΓòÉΓòÉΓòÉ
The confirm callback that the service layer returns to an application is sent
on a separate thread from that used by the application's executable file. The
application can post a message directly on the callback.
Ensure that your application does not block the callback thread.
ΓòÉΓòÉΓòÉ 11.3.3. Synchronous and Asynchronous Components ΓòÉΓòÉΓòÉ
The example components NAMES and NAMEDIR are both designed to respond to
requests in a synchronous manner. The component processes each request as it is
received and does not process subsequent requests until the previous request
has been answered.
You can take a synchronous component and modify it to function asynchronously
by doing the following:
Create a thread that is blocked until a command is received from a
management application.
When the command is received, the component instrumentation queues the
command to the waiting thread and returns from the DmiCiInvoke() function
call immediately. The service layer continues operation and does not call
the component again until the first command has completed.
The thread processes the command just as it would in a synchronous
situation, but after the thread issues the callback to the service layer,
it returns to the blocked state or terminates.
This enables the service layer to process other requests.
ΓòÉΓòÉΓòÉ 11.3.4. Debugging Overlay Instrumentation on Windows NT ΓòÉΓòÉΓòÉ
Overlay component instrumentation can be difficult to debug because of its
transitory nature. To facilitate this kind of debugging, you can use a debug
option when running the service layer on Windows NT. Refer to the SystemView
Agent for Win32 User's Guide for information on how to stop the service layer.
Because the service layer normally runs as a background process, you must stop
the service layer (if it's already running) before you use this option.
To start the service layer with the debug option, enter the following command
from a DOS command prompt:
START DMISLSRV DEBUG
If the subdirectory containing the service layer executable file is not in your
PATH statement, enter the appropriate drive and path as part of the command.
When the service layer is loaded, a debug address is displayed. When you set a
breakpoint at this address, execution stops just before the DmiCiInvoke()
function call is issued. At this point the overlay component DLL is already
loaded, and you can specify breakpoints in the instrumentation wherever you
need them.
You can display the version of the service layer on Windows NT by issuing the
following from a DOS command prompt:
DMISLSRV VERSION
This displays version information without starting the service layer. You can
issue this command while the service layer is running.
ΓòÉΓòÉΓòÉ 11.3.5. Service Layer Time-out ΓòÉΓòÉΓòÉ
If the Windows NT/Windows 95 service layer provided with SystemView Agent
issues a request to a component and the component takes longer than 15 seconds
to respond, the service layer automatically deregisters the component. The
service layer then terminates any other outstanding requests to the component.
Further requests sent to the component yield an error (RC=1003;
CPERR_CI_TERMINATED).
The DMI browser continues to display the component icon until the component is
deinstalled. If you attempt to expand the icon after the time-out has occurred,
the DMI browser returns an error.
