How To Revert To Previous Release in OPA For Successful Login to OPA (Doc ID 2541701.1)

Last updated on MAY 26, 2021

Applies to:

Oracle Policy Automation - Version 12.2.6 and later
Information in this document applies to any platform.

Goal

As per instructions in the OPA 19A documentation (https://documentation.custhelp.com/euf/assets/devdocs/cloud19a/PolicyAutomation/en/Default.htm#Guides/System_Administrator_Guide/Private_cloud/Upgrade_private_cloud.htm) to revert back to previous release of OPA version and successful login to Hub.

Step 6. Reverting to a previous version
If you need to revert to a previous version of OPA private cloud you should do the following.

- Ensure that you have a backup of your database from immediately before any upgrade took place.
- Undeploy all OPA web applications, and delete the OPA Datasource from Weblogic.
- Restore the database to one that coincides with the OPA version that you want to restore to.
- From the OPA private cloud install files, run a non-interactive install command, as per the Policy Automation Install Guide. Because you have an existing database, you should set the -existing-database switch for the install. This will use the restored database rather than create a new one.

Does this revert do a complete reinstall of Oracle Policy Automation HUB? Are there other steps needed to complete the revert of a previous version?
