Rolling back a previously applied Oracle patch package

You can roll back an Oracle patch package that has been applied to a node, and return the node to the previous patch level.

Before you begin

Ensure the following prerequisites are met:

• The Can Rollback option is selected in the attributes for the package.
• All OPatch IDs defined for the patch package are installed on that node.

To roll back an Oracle patch package that has already been applied to a node

1. From the Management Console main page, select Patching > Patch Repository in the Context Frame.
2. In the Patch Repository page, select the patch package that you want to uninstall, and select Rollback from the list box for that row.
3. In the Homes section of the Oracle Patch Rollback Candidates page, select a host, and click Next.
   
   
   
   You can view a list of the targets that were excluded from the rollback candidates list, including the reason why, by clicking Excluded Candidates.

4. In the Job Options page, specify any of the following Job options, and click Next.
5. In the Scheduling page, select when to run this job in the Job Execution field, and click Next.

6. If the Change Control page displays, populate the following fields, and click Next.

   Note

   The Change Control page appears only when change control is configured for your environment. See Configuring-change-control.

7. In the Summary page, review the information.
   To make changes, do the following:
   1. Click Go to to return to the provisioning step that you want to edit.
   2. Make your changes.
   3. Click Save and Review to return to the Summary page.
8. Specify your verification preferences.
   • To continue with database creation after the pre-verification tests have been successfully run without manual intervention, select Automatically Continue If All Tests Succeed.

   • To create the database without having first run the pre-verification steps, select Skip Pre-Verification Tests.

     Note

     The Skip Pre-Verification Tests option should only be used when you are certain all tests can succeed. The option skips verification and advances directly to the actual provisioning activity.

9. Click Execute Job or Schedule Job (depending on your selection in the Scheduling page).
