Use this procedure on each cluster node to perform in-place patching of Grid Infrastructure Management Repository (GIMR).

1. Download patches you want to apply from My Oracle Support:
   https://support.oracle.com

   Select the Patches and Updates tab to locate the patch.

   Oracle recommends that you select Recommended Patch Advisor, and enter the product group, release, and platform for your software. My Oracle Support provides you with a list of the most recent Release Updates (RUs) and Release Update Revisions (RURs).

   Place the patches in an accessible directory, such as /tmp.

2. Review the patch documentation for the patch you want to apply, and complete all required steps before starting the patch upgrade.
3. As the grid user, run the following command to perform the prerequisite checks:

   $ $ORACLE_HOME/bin/mgmtprepatchbootstrap.pl apply [inplace] --patchHome bootstrap_location 
   --sourceHome source_GIMR_home --id patch_ID_list

   For example:

   $ $ORACLE_HOME/bin/mgmtprepatchbootstrap.pl apply [inplace] --patchHome /tmp 
   --sourceHome /u01/app/21.0.0/gimr --id 123456

   Where:

   • patchHome is the location of the unzipped patch file.
   • sourceHome is the GIMR home that you are patching.

   Note:

   Do not use slash (/) at the end of the path.
4. Change directory to the /OPatch directory in the GIMR home. For example:

   $ cd GIMR_home/OPatch
   

5. Follow the instructions in the patch documentation to apply the patch. For example:

   $ ./opatch apply patch directory_location/patch_ID

6. Run the following command to apply the SQL patch:

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