Veritas Storage Foundation 5.1 SP1 for Oracle RAC Administrator"s Guide (5900-1512, April 2011)

See the Veritas Cluster Server Agent for Oracle Installation and Configuration

Guide for IMF-aware agents for Oracle.

See the Veritas Storage Foundation Cluster File System Installation Guide for

IMF-aware agents in CFS environments.

How intelligent resource monitoring works

When an IMF-enabled agent starts up, the agent initializes the IMF notification

module. After the resource is in a steady state, the agent registers the details that

are required to monitor the resource with the IMF notification module. For

example, the process agent registers the PIDs of the processes with the IMF

notification module. The agent's imf_getnotification function waits for any

resource state changes. When the IMF notification module notifies the

imf_getnotification function about a resource state change, the agent framework

runs the monitor agent function to ascertain the state of that resource. The agent

notifies the state change to VCS which takes appropriate action.

See “About the IMF notification module” on page 36.

Cluster configuration files

VCS uses two configuration files in a default configuration:

■ The main.cf file defines the entire cluster, including the cluster name, systems

in the cluster, and definitions of service groups and resources, in addition to

service group and resource dependencies.

■ The types.cf file defines the resource types. Each resource in a cluster is

identified by a unique name and classified according to its type. VCS includes

a set of pre-defined resource types for storage, networking, and application

services.

Additional files similar to types.cf may be present if you add agents. For example,

SF Oracle RAC includes additional resource types files, such as OracleTypes.cf,

PrivNIC.cf, and MultiPrivNIC.cf.

Oracle RAC

This section provides a brief description of Oracle Clusterware/Grid Infrastructure,

the Oracle Cluster Registry, application resources, and the voting disk.
