OCR Administration Utilities
There are a few utilities that are installed as part of the GI to help validate the OCR.

OCR Verification (ocrcheck) Utility
This utility checks the health of the OCR. Apart from generating information regarding the OCR, the ocrcheck utility
generates a log file in the directory from which this utility is executed.

[oracle@ssky3l11p1 ~]$ $GRID_HOME/bin/ocrcheck
Status of Oracle Cluster Registry is as follows :

[oracle@ssky3l11p1 ~]$

[root@ssky3l11p1 ~]# /u01/app/12.1.0/grid/bin/ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 4

■ in the preceding output, while the basic OCr check can be performed as “ oracle ” user, the logical corruption
check is only performed when the ocrcheck utility is executed as “ root ” user.
