Conflict Detection and Resolution

The easiest and quickest way to determine if you have a patch already applied that will conflict with another patch that will still be applied is through the One-off Patch ConflictDetectionandResolution method.

If no conflict is found you can apply the patch, otherwise you need to resolve the conflicts.

Applying the Patch in the Database Home

The OPatch utility automates the patch application for Oracle Grid Infrastructure Home and Oracle RAC Database Home. It operates by consulting the existing configuration and automating the steps required to patch both DB Home and GI Home.

Note: This is just a bug fix patch.

After applying the patch to the DB Home you can consult the list of patches applied using OPatch “lsinvetory”.

Removing the Database Home Patch

The patch rollback instructions will be different for GI and DB Home. The steps required for rollback in DB Home are listed below.
