Sample configuration file for removing a node from the cluster


Sample configuration file for removing a node from the cluster
Prev	Removing a node from SF Oracle RAC clusters	Next

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 saturn is as follows:

The existing cluster rac_cluster101 comprises three nodes galaxy, nebula, and saturn 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 "saturn" is removed from the cluster.

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

system galaxy (
        )
system nebula (
        )

       )

Note:

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