ΓòÉΓòÉΓòÉ <hidden> Keylock ΓòÉΓòÉΓòÉ

The Communications Manager keylock is a password protection system that
protects configurations by preventing access to certain functions.  If you need
access to keylocked functions, your system administrator can give you the
password.


ΓòÉΓòÉΓòÉ <hidden> Logical Unit (LU) ΓòÉΓòÉΓòÉ

A logical unit (LU) is a port through which a user can access a Systems Network
Architecture (SNA) network to communicate with others on the network and to use
the services provided by the network.

The LU contains a portion of the SNA software (called APPC) that accepts verbs
from your transaction programs (TPs) and acts on those verbs. By accepting
these verbs and acting upon them, LUs manage the exchange of data between TPs,
acting as intermediaries between the TPs and the SNA network.

An example of a verb is DEFINE_PARTNER_LU. The LU processes the actual
verb-code sent by the transaction program.

Communications Manager provides support for the following LU types:

o LU 0
o LU 1
o LU 2
o LU 3
o LU 4
o LU 6.0
o LU 6.2
o LU 7

Communication occurs only between LUs of the same LU type. For example, an LU 2
communicates with another LU 2; it does not communicate with an LU 3.


ΓòÉΓòÉΓòÉ <hidden> Local LU ΓòÉΓòÉΓòÉ

A local LU is an LU in your workstation that gives your transaction programs
(TPs) access to the network.


ΓòÉΓòÉΓòÉ <hidden> Partner LU ΓòÉΓòÉΓòÉ

A partner LU is an LU in a remote network device (for example, a workstation)
with which a local LU communicates over a network.


ΓòÉΓòÉΓòÉ <hidden> Data Link Control (DLC) ΓòÉΓòÉΓòÉ

Data link control (DLC) is a set of rules used by two nodes on a data link to
accomplish an orderly exchange of information.  DLC is synonymous with line
control.


ΓòÉΓòÉΓòÉ <hidden> Node ΓòÉΓòÉΓòÉ

A node is an end point of a link or junction common to two or more links in a
network.  Nodes can be linked to host processors, communication controllers,
cluster controllers, terminals, or workstations.


ΓòÉΓòÉΓòÉ <hidden> Network Node ΓòÉΓòÉΓòÉ

A network node is a node that serves end nodes in its network with the full
range of Advanced Peer-to-Peer Networking (APPN)* services, which include:

o Intermediate session routing
o Directory services
o Topology and route selection services


ΓòÉΓòÉΓòÉ <hidden> Peer Node ΓòÉΓòÉΓòÉ

A peer node is a node that exists on the same layer as another node.  You can
often select peer node when you are not sure what the partner node type is.


ΓòÉΓòÉΓòÉ <hidden> End Node ΓòÉΓòÉΓòÉ

An end node is a node that participates in its Advanced Peer-to-Peer Networking
(APPN)* using the services of a network node server.


ΓòÉΓòÉΓòÉ <hidden> Low Entry Networking (LEN) Node ΓòÉΓòÉΓòÉ

A low-entry networking (LEN) node is a type 2.1 node that can participate in
advanced program-to-program communication (APPC), but cannot make direct use of
the Advanced Peer-to-Peer Networking (APPN)* services provided by a network
node server.


ΓòÉΓòÉΓòÉ <hidden> Control Point (CP) ΓòÉΓòÉΓòÉ

The control point (CP) manages the node and its resources.  For example, in an
Advanced Peer-to-Peer Networking (APPN)* end node, the CP must communicate with
the CP in an adjacent network node to obtain APPN network services. In an APPN
network node, the CP must communicate with the CPs in adjacent network nodes to
manage the network. The CP directs such functions as activating and
deactivating the following:

o Adapters
o Links
o Logical units (LUs)

The CP of a local node is the SNA component that manages and monitors the
resources of a node. Each node of an SNA network contains a CP. When you
specify a local name, it becomes the CP name for your workstation. CP names are
used by the SNA feature profile for all of the following SNA features of
Communications Manager:

o SNA gateway
o 3270 (non-coaxial) emulation
o 5250 emulation
o APPC
o APPN


ΓòÉΓòÉΓòÉ <hidden> Network ID ΓòÉΓòÉΓòÉ

Assigning an incorrect network ID can produce network connectivity problems. If
you are creating a network ID for your configuration, check with your system
administrator for an ID suitable for your application.  If you do not have a
system administrator, refer to Network Administration and Subsystem Management
Guide for recommendations in choosing a network ID.


ΓòÉΓòÉΓòÉ <hidden> Server ΓòÉΓòÉΓòÉ

On a local area network, a server is a data station that provides facilities to
other workstations, such as a file server, a print server, a mail server.


ΓòÉΓòÉΓòÉ <hidden> Station Negotiation ΓòÉΓòÉΓòÉ

Station negotiation is a capability that allows two LUs to negotiate the
parameters of a session when the session is being activated.


ΓòÉΓòÉΓòÉ <hidden> Transmission Group (TG) ΓòÉΓòÉΓòÉ

A transmission group (TG) is a group of links between adjacent subarea nodes
appearing as a single logical link for the routing of messages.

Note:  A transmission group may consist of one or more SDLC links (parallel
links) or of a single System/370* channel.


ΓòÉΓòÉΓòÉ <hidden> Transmission Group Identifier ΓòÉΓòÉΓòÉ

A transmission group identifier is a set of three values, unique for each
transmission group, consisting of the subarea addresses of the two adjacent
nodes connected by the transmission group, and the transmission group number
(1-255).


ΓòÉΓòÉΓòÉ <hidden> Link Station ΓòÉΓòÉΓòÉ

A link station is the combination of hardware and software that allows a node
to attach to and provide control for a link.


ΓòÉΓòÉΓòÉ <hidden> Bind ΓòÉΓòÉΓòÉ

A bind is a request to activate a session between two logical units.


ΓòÉΓòÉΓòÉ <hidden> Primary Logical Unit (PLU) ΓòÉΓòÉΓòÉ

A primary logical unit (PLU) is the logical unit (LU) that contains the primary
half-session for a particular LU-LU session.

different active LU-LU sessions.


ΓòÉΓòÉΓòÉ <hidden> Secondary Logical Unit (SLU) ΓòÉΓòÉΓòÉ

A secondary logical unit (SLU) is the logical unit (LU) that contains the
secondary half-session for a particular LU-LU session.


ΓòÉΓòÉΓòÉ <hidden> Basic Transmission Unit (BTU) ΓòÉΓòÉΓòÉ

basic transmission unit (BTU)
   The unit of data and control information passed between path control
   components. A BTU can consist of one or more path information units (PIUs).

PIU
   A message unit consisting of a transmission header (TH) alone, or a TH
   followed by a basic information unit (BIU) or BIU segment.

TH
   Control information, optionally followed by a BIU or a BIU segment, that is
   created and used by path control to route message units and to control their
   flow within the network.

BIU
   The unit of data and control information passed between half-sessions.  It
   consists of a request/response header (RH) followed by a request/response
   unit (RU).

   A BIU segment is the portion of a BIU that is contained within a PIU.  It
   consists of either a request/response header (RH) followed by all or part of
   a request/response unit (RU), or of only a part of an RU.

RH
   A header that precedes an RU. An RU is a message unit that contains control
   information such as a request code, or function management (FM) headers,
   end-user data, or both.

FM header
   One or more headers optionally present in the leading request units (RUs) of
   an RU chain that allow a half-session in an LU-LU session to:

   o Select a destination as a session partner and control the way in which the
     end-user data it sends is handled at the destination

   o Change the destination or characteristics of data during a session

   o Transmit between the session partners status or user information about the
     destination; for example, whether it is a program or device.

   Note:  FM headers can be used on LU-LU session types 0, 1, 4, and 6.


ΓòÉΓòÉΓòÉ <hidden> Class of Service (COS) ΓòÉΓòÉΓòÉ

A class of service (COS) is a designation of the path control network
characteristics, such as path security, transmission priority, and bandwidth,
that apply to a particular session.  The end user designates class of service
at session initiation by using a symbolic name that is mapped into a list of
virtual routes, any one of which can be selected for the session to provide the
requested level of service.


ΓòÉΓòÉΓòÉ <hidden> Contention ΓòÉΓòÉΓòÉ

In a local area network, contention is a situation in which two or more data
stations are allowed by the protocol to start transmitting concurrently and
thus risk collision.

Contention mode is a mode of transmission in which any station may transmit
whenever the line is available.  If stations transmit simultaneously, protocols
determine who wins contention.


ΓòÉΓòÉΓòÉ <hidden> Request and Response Unit (RU) ΓòÉΓòÉΓòÉ

A request and response unit (RU) is a message unit that contains control
information such as a request code (or function management (FM) headers) and
end-user data.

An FM header is one or more headers that may be present in the leading request
units (RUs) of an RU chain. The FM headers allow a half-session in an LU-LU
session to:

o Select a destination as session partner and control the way in which the
  end-user data it sends are handled at the destination

o Change the destination or characteristics of data during a session

o Transmit between the session partners any status or user information about
  the destination; for example, whether it is a program or device.

Note:  FM headers can be used on LU-LU session types 0, 1, 4, and 6.


ΓòÉΓòÉΓòÉ <hidden> Topology ΓòÉΓòÉΓòÉ

A topology is the schematic arrangement of the links and nodes of a network.


ΓòÉΓòÉΓòÉ <hidden> Alias ΓòÉΓòÉΓòÉ

An alias is a nickname used to refer to a logical unit (LU) instead of having
to specify a fully qualified LU name.

Alias names are used for convenience or ease of recognition within your
network.  If a network administrator switches workstations to different nodes
for network management reasons, the client applications are not affected.

For example, if you have an LU on your system whose fully qualified name is
defined as XYZQ32L.FKKS237, you can give it an alias name, like Pam.  Then the
transaction programs (TPs) used by others on your network can simply use the
alias name of Pam when they communicate with your workstation as a partner LU.
They will not have to specify the fully qualified LU name.  If the network
administrator decides to rename the LU from FKKS237 to SAFSDFJ, you simply need
to update the name in your LU definition.  The TPs on your network do not have
to be updated because they can continue to refer to the partner LU as Pam.


ΓòÉΓòÉΓòÉ <hidden> Mode ΓòÉΓòÉΓòÉ

A mode is a set of commonly grouped transmission characteristics that control
sessions, such as class of service and maximum size of the request and response
units (RUs) that are exchanged.


ΓòÉΓòÉΓòÉ <hidden> Configuration ΓòÉΓòÉΓòÉ

A configuration is a file where Communications Manager stores the statements
that it generates from the information you provide while using Configuration
Setup. These statements (generally known as verbs) determine how a workstation
communicates with a network.

Communications Manager stores SNA configuration and system management verbs in
the filename.NDF configuration file, where filename is the name of the
configuration you specify in the Open Communications Manager Configuration
window.

Advanced users can modify these verbs directly by editing the filename.NDF file
using a text editor program.

Note:  For more detailed information on editing this file, refer to the
APPNV.CTL text file in the CMLIB directory.


ΓòÉΓòÉΓòÉ <hidden> Hexadecimal ΓòÉΓòÉΓòÉ

Some fields require a hexadecimal value.  The hexadecimal numbering system has
a base of sixteen.  Valid numbers use the digits 0 through 9 and characters A
through F, where A represents 10 and F represents 15.

The length of a hexadecimal value is usually expressed in bytes. For example, a
field may require you to enter an 8-byte hexadecimal number.  A single byte is
made up of two places, each of which can be filled with a number or a
character.

To enter a hexadecimal number in a field, type the characters X' followed by
the hexadecimal value and the ending single quote. For example:

One-byte hexadecimal number
   X'09'

Eight-byte hexadecimal number
   X'A7BB49C8D75F6011'

You can accept the default value supplied by the configuration program, edit
the default, or choose a new value. The first three characters default to
X'05D'.

If you type a new value, it must be a hexadecimal value between 00000000 and
FFFFFFFF. Do not enclose the value in the hexadecimal symbols. For example,
enter 05D01ABF, not X'05D01ABF'. When you type fewer than five digits in the
second part of the field, the system fills in the value with leading zeros.

In link station negotiations, these eight characters determine which link
workstation is primary and which is secondary. The workstation with the higher
value becomes the primary link workstation. If equal, both stations generate a
random number to determine which is primary.

o The node address or the medium access control (MAC) address defined in the
  configuration for the controller's network adapter on an IBM Token-Ring
  network or an IBM PC network

o A permanent address that is encoded in the controller's network adapter by
  the manufacturer

o An address assigned within your network to the controller's network adapter.

Your LAN administrator can tell you the LAN destination address to use.

If you enter a value in the Adjacent node ID field, you cannot enter a value in
the LAN destination address field. To complete this window, you need to enter

ΓòÉΓòÉΓòÉ <hidden> Editing the .NDF File to Configure an Incoming Connection ΓòÉΓòÉΓòÉ

To configure an incoming connection for a LAN DLC type without specifying a LAN
destination address, you can either specify an adjacent node ID on this window,
or you can edit the .NDF configuration file directly.

If you choose to edit the .NDF file, you need to add an FQ_ADJACENT_CP_NAME to
the DEFINE_LOGICAL_LINK verb.  In this case, ACTIVATE_AT_STARTUP cannot be YES
and LINK_STATION_ROLE cannot be PRIMARY.

Note:  To edit the .NDF file directly, select Cancel instead of OK to exit this
window. This allows you to exit the window without specifying either a LAN
destination address or an adjacent node ID for the connection.

Continue closing windows to back out of the configuration.  Then, edit the .NDF
file.


ΓòÉΓòÉΓòÉ 69. Address Format ΓòÉΓòÉΓòÉ

Address format defines the format of the LAN destination address at the remote
workstation.

The two address formats are:

Token Ring
   The token ring address format is most significant bit.  This means that the
   highest bit within each byte of the address is sent across the LAN first
   when establishing the connection.

Ethernet
   The Ethernet address format is least significant bit.  This means that the
   lowest bit within each byte of the address is sent across the LAN first when
   establishing the connection.

Select the address format of the LAN destination address at the remote
workstation.

The default selection is Token Ring.

If you type a value, it must be a hexadecimal value between 00000000 and
FFFFFFFF. Do not enclose the value in the hexadecimal symbols. For example,
enter 05D01ABF, not X'05D01ABF'. If you type fewer than eight digits in this
field, the system fills in the value with leading zeros.

In station negotiations, the adjacent node ID determines which link workstation
is primary and which is secondary. The workstation with the higher value
becomes the primary link workstation. If equal, both workstations generate a
random number to determine which is primary.

Note:  If you specify a value for the destination information field, you cannot
enter a value in Adjacent node ID.

If you enter a value in Adjacent node ID instead of specifying a value in the
destination information field, the link can be activated only by the partner
node.

The minimum number of tokens you can configure must be at least the number of
tokens required to support one session at the selected compression level. For
example, if you select the LZ9 compression level, you need to configure at
least 38 tokens. This is because LZ9 decompression requires 18 tokens and LZ9
compression requires 20 tokens. However, all 38 tokens might not be used to
establish one session. Each emulator session requires 22 tokens: 18 tokens for
LZ9 decompression and 4 tokens for RLE compression, with 16 tokens remaining.

When you are defining the number of tokens, you need to allocate enough tokens
for each session.  For example, each emulator session requires 22 tokens: 18
tokens for LZ9 decompression and 4 tokens for RLE compression. For two emulator
sessions using compression, you need to configure at least 44 tokens.

For more detailed explanations about the data compression settings, see Network
Administration and Subsystem Management Guide.

If you want general help for the entire window, press F2 now.


ΓòÉΓòÉΓòÉ 113. Mode Session Limit ΓòÉΓòÉΓòÉ

Mode session limit specifies the maximum number of logical unit-to-logical unit
(LU-LU) sessions that you want active at one time for the LUs using this mode.

You can enter any value from 0 to 32767.  Raise the number if your key
application programs are coming up too slowly.  Lower the number to improve
overall system response time.  In actual communications, the partner LU can
reduce this number if necessary.

If you are unsure about what value to enter here, use the default value.

Note:  The default value for Mode session limit is 8.

If you want general help for the entire window, press F2 now.


ΓòÉΓòÉΓòÉ <hidden> Improving the Efficiency of Network Operations ΓòÉΓòÉΓòÉ

You adjust session limits to improve the efficiency of your network operations.
These adjustments are largely a matter of trial and error. Try an adjustment,
note the effects, and if necessary, adjust again.

The limits established on sessions in this mode are just some of the factors
that may affect network efficiency.  If adjusting session limits does not
improve system performance, you must look to other probable causes, such as the
number and kind of sessions required by various applications, and the size and
speed of the communicating workstations.


ΓòÉΓòÉΓòÉ 114. Minimum Contention Winners ΓòÉΓòÉΓòÉ

Minimum contention winners specifies the minimum number of sessions in which
you want a logical unit (LU) in this mode to win in a contention with a partner
LU

You can type a value up to 32767.

The number you enter must be less than or equal to the value you typed in the
Mode session limit field above.

If you are unsure of what to enter, leave the value at 0.  The node
automatically selects the winner when needed.

When LUs at each end of a session try to start a conversation at the same time,
they enter a potential race condition that could result in communication
errors.  Communications Manager minimizes such errors by selecting which of the
LUs can start without requesting permission from the LU at the other end. The
LU that can start without permission is known as the contention winner.  The
loser can only start a conversation when it has requested and received
permission from its partner LU.

If you want general help for the entire window, press F2 now.


ΓòÉΓòÉΓòÉ 115. Receive Pacing Window ΓòÉΓòÉΓòÉ

Receive pacing window contains the number of RUs that a sending node can
transmit before receiving a pacing response from the receiving node. A pacing
response is a message sent by the receiving node to the sending node indicating
that data transmission can continue.

If one node sends data faster than the other node can receive and process it,
the receiving node may be forced into extensive recovery action. Allowing the
receiving node to set the pace for data transmission helps to ensure that the
data sent will be received and processed with greater accuracy.

Specify a value, in RUs, by typing a number from 0 to 63.

If you type 0, this indicates that no session pacing will be performed.

If you are unsure about what to enter, leave the value at the default. The
actual value used may be negotiated between nodes when the session is started.

If you want general help for the entire window, press F2 now.


ΓòÉΓòÉΓòÉ 116. Compression Need ΓòÉΓòÉΓòÉ

for sessions using this mode name.

The RU Size choices are as follows:

Default RU size
   When you select Default RU size, the lower boundary for the maximum RU size
   is 256 bytes and the upper boundary is equal to the largest RU that the link
   can transfer to without segmenting the data.

Maximum RU size
   When you select Maximum RU size, the maximum RU size is smaller than the
   largest size that the link can transfer to.

   For example, if two links are defined and data arrives on one link and the
   data is then sent out to another link, the maximum RU size for the two links
   cannot be the same.

   When you select this option, you are prompted to enter the size of the
   largest RU (in bytes) to be sent or received on sessions using this mode
   name.

ΓòÉΓòÉΓòÉ 140. Security Type ΓòÉΓòÉΓòÉ

Security type is the level of security information that Attach Manager sends to
the partner LU on a conversation allocation request. If present, the security
information consists of a user ID and password or a user ID and an indication
that the security information has already been verified.

When a local transaction program (TP) (a TP stored on your workstation) uses
CPI Communications to initiate a conversation with a partner TP, the partner TP
may require security information before it allows the conversation to begin.

Refer to the documentation for the local TP to determine which Security type to
select.

Select one of the following options:

Same
   Attach Manager sends the partner LU an allocation request that includes the
   same level of access security information as that in the request received
   from the partner LU.

   If the partner LU sent no security information, the local LU sends no
   security information.

   If the partner LU includes a user ID in the inbound allocation request, the
   local LU returns an allocation request containing the same user ID.  The
   local LU also returns an indication that the user ID has already been
   verified.

   If OS/2 User Profile Management is being used, the local LU uses this
   facility to determine the user ID returned to the partner LU in the
   allocation request.

   Along with the user ID, the partner LU is sent an indication that the user
   ID has already been verified.

None
   Attach Manager sends the partner LU an allocation request that includes no
   security information.

Program
   Attach manager sends the partner LU an allocation request that includes a
   user ID and password that you define. When you finish with the CPI
   Communications Side Information window, select Continue.  The Program
   Security window appears, in which you define the user ID and password.
