B) How To Relink The Oracle Grid Infrastructure RAC/Cluster Installation.
 

In order to relink the Oracle Grid Infrastructure RAC/Cluster Installation, please follow the next steps after stopping all the services running:

1) As root OS user, please unlock the Grid Infrastructure Oracle Home (on every node) as follows:

# cd < Grid Infrastructure Oracle Home >/crs/install
# perl rootcrs.pl -unlock

Note: On 12.1/12.2/18c releases, rootcrs.sh can be used instead of rootcrs.pl. Command as "rootcrs.sh -unlock"

2) As the Oracle Grid Infrastructure owner (on every node) relink the Grid Infrastructure Oracle Home as follows:

$ export ORACLE_HOME=< Grid Infrastructure Oracle Home >
$ < Grid Infrastructure Oracle Home>/bin/relink all

3) As root OS user again, please execute the next commands (on every node):

# cd < Grid Infrastructure Oracle Home >/rdbms/install/
# ./rootadd_rdbms.sh
# cd < Grid Infrastructure Oracle Home >/crs/install
# perl rootcrs.pl -patch

On 12.1, use "rootcrs.sh -patch". On 12.2/18c, use "rootcrs.sh -lock" then "crsctl start crs"

Note: CRS services (CRS, CSS ASM instances, diskgroups, listeners, DB instances, etc.) will automatically start.
 
4) Please review the relink.log file located at the following directory (to confirm or discard any error):
