Storage Foundation for Oracle® RAC 7.4.1 Configuration and Upgrade Guide - Solaris

Platform: Solaris

Sample configuration file for removing a node from the cluster

You may use this sample file as reference information to understand the configuration changes involved when you remove a node from a cluster.

The existing sample configuration before removing the node sys5 is as follows:

The existing cluster clus1 comprises three nodes sys1, sys2, and sys5 and hosts a single database.
The Oracle database is stored on CFS.
The database is managed by the VCS agent for Oracle.
The agent starts, stops, and monitors the database.
Only one private IP address is configured for Oracle Clusterware. The private IP address is managed by the PrivNIC agent for high availability.
The Oracle Cluster Registry (OCR) and voting disk are stored on CFS.

Note:

The following sample file shows in bold the configuration information that is removed when the node "sys5" is removed from the cluster.

include "types.cf"
include "CFSTypes.cf"
include "CVMTypes.cf"
include "OracleTypes.cf"
include "PrivNIC.cf"

Note:

In the following group oradb1_grp, the sys5 node must be removed.

Note:

In the following Oracle resource, the sys5 node information must be removed.
