Use this procedure on each cluster node for in-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. As the grid user, run the following command to perform the prerequisite checks:

   $ $ORACLE_HOME/bin/mgmtprepatchbootstrap.pl rollback [inplace] --sourceHome source_GIMR_home --id patch_ID_list

3. Change directory to the /OPatch directory in the GIMR home. For example:

   $ cd GIMR_home/OPatch
   

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

   # ./opatch rollback directory_location/patch_ID

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

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