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.
Brower, Purvy, Daniel, Sinykin & Smith [Page 1]
RFC 1697 RDBMS-MIB August 1994
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.
Brower, Purvy, Daniel, Sinykin & Smith [Page 2]
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.
Brower, Purvy, Daniel, Sinykin & Smith [Page 4]
RFC 1697 RDBMS-MIB August 1994
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

DESCRIPTION
"The table of additional information about database servers.
Entries in this table correspond to applications in the
APPLICATION-MIB applTable. Some objects in that table are
application-specific. When they are associated with an RDBMS
server in this table, the objects have the following
meanings.
applName - The name of this server, i.e., the process or
group of processes providing access to this database. The
exact format will be product and host specific.
applVersion - The version number of this server, in product
specific format.
applOperStatus - up(1) means operational and available for
general use. down(2) means the server is not available for
use, but is known to the agent. The other states have broad
meaning, and may need to be supplemented by the vendor
private MIB. Halted(3) implies an administrative state of
unavailability. Congested(4) implies a resource or or
administrative limit is prohibiting new inbound associations.
The 'available soon' description of restarting(5) may include
an indeterminate amount of recovery.
applLastChange is the time the agent noticed the most recent
change to applOperStatus.
applInboundAssociation is the number of currently active
local and remote conversations (usually SQL connects).
applOutboundAssociations is not provided by this MIB.
applAccumulatedInboundAssociations is the total number of
local and remote conversations started since the server came
up.
applAccumulatedOutbound associations is not provided by this
MIB.
applLastInboundActivity is the time the most recent local or
Brower, Purvy, Daniel, Sinykin & Smith [Page 19]

remote conversation was attempted or disconnected.
applLastOutboundActivity is not provided by this MIB.
applRejectedInboundAssociations is the number of local or
remote conversations rejected by the server for
administrative reasons or because of resource limitations.
applFailedOutboundAssociations is not provided by this MIB."
