How to Check Cluster Name for Oracle RAC

Just a quick short post in the late hours ( ­čÖé ) on how to┬ácheck the cluster name for Oracle RAC.

You can find out the cluster name with $ORA_CRS_HOME/bin/cemutlo -n

[grid@oel-ocm-pc2 ~]$ . oraenv
ORACLE_SID = [+ASM2] ? +ASM2
The Oracle base remains unchanged with value /u01/app/grid
[grid@oel-ocm-pc2 ~]$
[grid@oel-ocm-pc2 ~]$ cemutlo -n
ocm-cluster
[grid@oel-ocm-pc2 ~]$

Further, if you want to check the clusterware version installed,
run $ORA_CRS_HOME/bin/crsctl query crs softwareversion

[grid@oel-ocm-pc2 ~]$ crsctl query crs softwareversion
Oracle Clusterware version on node [oel-ocm-pc2] is [11.2.0.3.0]
