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

Listener ORACLE_HOME [ /oracle/app/grid/11.2.0/grid ]:
Password for SYS user:

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
[root@racn01 ~]#
