- 1. Introduction
-
- This memo defines a portion of the Management Information Base (MIB)
- for use with network management protocols in the Internet community.
- In particular, it describes managed objects used for managing
- relational database (RDBMS) implementations.

- 2. The SNMPv2 Network Management Framework
-
- The SNMPv2 Network Management Framework consists of four major
- components. They are:
-
- o RFC 1442 [1] which defines the SMI, the mechanisms used for
- describing and naming objects for the purpose of management.
-
- o STD 17, RFC 1213 [2] defines MIB-II, the core set of managed
- objects for the Internet suite of protocols.
-
- o RFC 1445 [3] which defines the administrative and other
- architectural aspects of the framework.
-
- o RFC 1448 [4] which defines the protocol used for network
- access to managed objects.
-
- o RFC 1443 [5] which describes textual conventions for the
- framework.
-
- The framework permits new objects to be defined for the purpose of
- experimentation and evaluation. In particular, the RDBMS-MIB can be
- seen as an extension of
-
- o RFC 1565 [6] which defines the MIB for monitoring network
- service applications.
-
- 2.1. Object Definitions
-
- Managed objects are accessed via a virtual information store, termed
- the Management Information Base or MIB. Objects in the MIB are
- defined using the subset of Abstract Syntax Notation One (ASN.1)
- defined in the SMI. In particular, each object type is named by an
- OBJECT IDENTIFIER, an administratively assigned name. The object
- type together with an object instance serves to uniquely identify a
- specific instantiation of the object. For human convenience, we
- often use a textual string, termed the descriptor, to refer to the
- object type.
-
- 3. Overview
-
- The RDBMS-MIB contains objects that may be used to manage relational
- database implementations. Specifically, it contains information on
- installed databases, servers, and on the relation of databases and
- servers. The terms used in this database are described below.
-
-
-
-
-

-
- RFC 1697 RDBMS-MIB August 1994
-
-
- 3.1. Terminology
-
- Vendors and Products
- are providers of database systems on a host. These vendors
- may have more than one database product that is manageable
- through this MIB. On a host, there may be systems from
- multiple vendors, multiple systems from a single vendor, or
- any other combination. There may be a private MIB for each
- vendor, and this may be located using the PrivateMibOID
- objects in some of the tables.
-
- Databases
- are collections of interrelated data organized according to a
- schema to serve one or more applications. A database is, for
- purposes of this MIB, a collection of tables whose
- organization is based on the relational model. There may be
- one or more databases available in each system on the host
- from each product. In the MIB, data about databases is
- captured in the rdbmsDbTable and the rdbmsDbInfoTable, each
- with one row per database.
-
- Relational Database Management System (RDBMS)
- A collection of integrated services which support database
- management and together support and control the creation, use
- and maintenance of relational databases. Servers as defined
- in this MIB provide the functions of the RDBMS.
-
- Servers
- are entities that provide access to databases. For this MIB,
- servers are defined to be entities that may exist
- independently of other servers. A server may or may not be a
- single process, based on its independence from other
- processes. In this MIB, information about servers is
- captured in the rdbmsSvrTable, the rdbmsSvrInfoTable, each
- with one row per server extending the applTable from the
- APPLICATION-MIB of RFC 1565. The rdbmsSvrTable and
- rdbmsSvrInfoTable are both indexed by the applIndex of that
- MIB.
-
- Associations
- Inbound associations are local or remote conversations,
- usually instances of the SQL CONNECT statement, as made
- visible in servers. The MIB does not currently reveal
- individual associations; there are association counters in
- the dbmsSvrInfoTable and the applTable.
-
- There are also relationships between servers and databases. All
- obvious relationships are possible and supported:
-
-
-
- Brower, Purvy, Daniel, Sinykin & Smith [Page 3]
-
- RFC 1697 RDBMS-MIB August 1994
-
-
- o 1 database : 1 server
-
- o 1 database : many servers
-
- o many databases : 1 server
-
- o many databases : many servers
-
- 3.2. Structure and Features
-
- The information in this MIB module is organized into nine tables,
- twelve potentially writable objects, and two traps, as follows.
-
- 3.2.1. Tables
-
- o databases installed on a host/system (rdbmsDbTable)
-
- o actively opened databases (rdbmsDbInfoTable)
-
- o database configuration parameters (rdbmsDbParamTable)
-
- o database limited resources (rdbmsDbLimitedResourceTable)
-
- o database servers installed on a system (rdbmsSrvTable)
-
- o active database servers (rdbmsSrvInfoTable)
-
- o configuration parameters for a server (rdbmsSrvParamTable)
-
- o server limited resources (rdbmsSrvLimitedResourceTable)
-
- o relation of servers and databases on a host (rdbmsRelTable)
-
- These entities have broad applicability among database systems, and
- are enough for many monitoring tasks. They are far from adequate for
- detailed management or performance monitoring of specific database
- products. This gap is expected to be filled with vendor and product
- specific MIBs addressing the entities that have not been codified
- here.

-
-
- 3.2.2. Writable objects
-
- The MIB requires no writable objects for conformance. There is no
- expectation that RDBMS systems may be actively managed through this
- MIB. However, the RDBMS-MIB supports the capability to modify the
- following objects if the implementor so chooses.
-
- o rdbmsDbContact
-
- o rdbmsDbInfoSizeAllocated
-
- o rdbmsDbParamCurrValue
-
- o rdbmsDbParamComment rdbmsDbLimitedResourceLimit
-
- o rdbmsDbLimitedResourceDescription
-
- o rdbmsSrvContact
-
- o rdbmsSrvInfoMaxInboundAssociations
-
- o rdbmsSrvParamCurrValue
-
- o rdbmsSrvParamComment
-
- o rdbmsSrvLimitedResourceLimit
-
- o rdbmsSrvLimitedResourceDescription
-
- 3.2.3. Traps
-
- The RDBMS-MIB contains two traps:
-
- o rdbmsStateChange
-
- o rdbmsOutOfSpace
