OCR Integrity Failure

Checking OCR Integrity Failure 

Today's while doing 12cR2 upgrade we experience the OLR integrity failure during pre check at upgrade.  So I check the permission and came to know the permission for my local OLR is oracle:oinstall on node 1. So I validated the OCR/OLR integrity and found every thing fine instead of permission on my local OLR has changed now. 

So I manually fix the permission issue and continue the upgrade.

[oracle@rac131 12.2.0.1]$ cat -n /etc/oraInst.loc

     1  inventory_loc=/u01/app/oraInventory

     2  inst_group=oinstall

[oracle@rac131 12.2.0.1]$ cluvfy comp olr -verbose
