Use this procedure on each cluster node for out-of-place Grid Infrastructure Management Repository (GIMR) patch rollback, in case of a failure or an error.

1. Review the patch documentation for the patch you want to rollback, and complete all required steps before starting the rollback.
2. Change directory to the /OPatch directory in the cloned GIMR home. For example:

   $ cd GIMR_home/OPatch
   

3. Follow the instructions in the patch documentation to rollback the patch. For example:

   # ./opatch rollback directory_location/patch_ID

4. Run the following command to rollback the SQL patch:

   $ $ORACLE_HOME/bin/mgmtca applyDatapatch -postPatchRollback -id patch_ID_list -sourceHome source_GIMR_home
