oraclednaTo relink Oracle Grid Infrastructure RAC/Cluster installation, we must stop CRS, unlock the Grid home, run the relink process as the Grid owner, and then re-lock/start CRS.
This procedure is required after OS patching or upgrades to ensure Oracle Clusterware and ASM binaries are properly rebuilt.
1. Stop CRS on first node.

2) As root OS user, unlock the Grid Infrastructure Home
[root@racnode1 ~]# cd /u01/app/19c/grid/crs/install
[root@racnode1 install]# rootcrs.sh -unlock
Using configuration parameter file: /u01/app/19c/grid/crs/install/crsconfig_params
The log of current session can be found at:
/u01/app/grid/crsdata/racnode1/crsconfig/crsunlock_racnode1_2026-05-28_11-13-46AM.log

Note: On 12.1/12.2/19c releases, rootcrs.sh can be used instead of rootcrs.pl. Command as “rootcrs.sh -unlock”
3) As the Oracle Grid Infrastructure owner, relink the Grid Infrastructure Home as follows:
[root@racnode1 ~]# su – grid
[grid@racnode1 ~]$ export ORACLE_HOME=/u01/app/19c/grid
[grid@racnode1 ~]$ /u01/app/19c/grid/bin/relink all
writing relink log to: /u01/app/19c/grid/install/relinkActions2026-05-28_11-20-29AM.log
4) As root OS user, execute the below command
[grid@racnode1 ~]$ su – root
[root@racnode1 ~]# cd /u01/app/19c/grid/rdbms/install/
[root@racnode1 install]# ./rootadd_rdbms.sh
—
[root@racnode1 ~]# cd /u01/app/19c/grid/crs/install
[root@racnode1 install]# rootcrs.sh -lock
Using configuration parameter file: /u01/app/19c/grid/crs/install/crsconfig_params
The log of current session can be found at:
/u01/app/grid/crsdata/racnode1/crsconfig/crslock_racnode1_2026-05-28_11-27-38AM.log

Note: On 12.1, use “rootcrs.sh -patch”.
Note: On 12.2/21c, use “rootcrs.sh -lock” then “crsctl start crs”
Note: On 12/21c, <GI_HOME>/crs/install/rootcrs.sh -postpatch, can be used to start and lock the GI home
5. As root user, start the CRS on node1.
[root@racnode1 ~]# crsctl start crs
CRS-4123: Oracle High Availability Services has been started.
5. Peform the 1 to 5 steps on node2.
[root@racnode2 install]# crsctl start crs
CRS-4123: Oracle High Availability Services has been started.
[root@racnode2 ~]# crsctl status res -t
