Confirming Oracle Clusterware Function

After Oracle Grid Infrastructure installation, confirm that your Oracle Clusterware installation is installed and running correctly.

After installation, log in as root, and use the following command syntax to confirm that your Oracle Clusterware installation is installed and running correctly:

crsctl check cluster -all

For example:

$ crsctl check cluster -all
 
**************************************************************
node1:
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
**************************************************************
node2:
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
**************************************************************
node3:
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
**************************************************************

Note:

After installation is complete, do not remove manually or run cron jobs that remove /tmp/.oracle or /var/tmp/.oracle or its files while Oracle Clusterware is up. If you remove these files, then Oracle Clusterware could encounter intermittent hangs, and you will encounter error CRS-0184: Cannot communicate with the CRS daemon.
