Oracle Clusterware / Grid Infrastructure: How to determine the configured name of your cluster?

Problem description:

You need to know the cluster name defined during the installation of Oracle Clusterware / Oracle Grid Infrastructure. Maybe because you are configuring Oracle Enterprise Manager Database Console for one of your RAC Databases via emca:

[oracle@racn01 ~]$ emca -config dbcontrol db -repos create -cluster

Enter the following information:
Database unique name: RACDB
Service name: RACDB
Listener port number: 1521
Listener ORACLE_HOME [ /oracle/app/grid/11.2.0/grid ]:
Password for SYS user: 
Password for DBSNMP user: 
Password for SYSMAN user: 
Cluster name:

 
Problem resolution:

Oracle Clusterware’s command “cemutlo” can be used to determine the name defined for your cluster during the installation:

[root@racn01 ~]# /oracle/app/grid/11.2.0/grid/bin/cemutlo -n
playground
[root@racn01 ~]#

    you can also use “$GRID_HOME/bin/olsnodes -c”

      Thanks Herve, absolutely right. This also does the trick.

      [root@ racn01 ~]# /oracle/app/grid/11.2.0/grid/bin/olsnodes -c
      playground
      [root@ racn01 ~]#
