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

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 delays, and you will encounter error CRS-0184: Cannot communicate with the CRS daemon.
