Run Pre-Upgrade Readiness Check

To identify potential issues with the upgrade, Oracle recommends that you run a readiness check before you start the upgrade process. Be aware that the readiness check may not be able to discover all potential issues with your upgrade. An upgrade may still fail, even if the readiness check reports success.

The Upgrade Assistant readiness check performs a read-only, pre-upgrade review of your Fusion Middleware schemas and WebLogic domain configurations that are at a supported starting point. The review is a read-only operation.

The readiness check generates a formatted, time-stamped readiness report so you can address potential issues before you attempt the actual upgrade. If no issues are detected, you can begin the upgrade process. Oracle recommends that you read this report thoroughly before performing an upgrade.

Once the new 12.2.1.4 ORACLE_HOME is created and Oracle WebLogic Server, Oracle Fusion Middleware Infrastructure Software, and Oracle Forms and Reports Servers are installed, run a pre-upgrade readiness check. You must run this check separately for FRDomain and OPAdomain.

1. Run the following command to start the pre-upgrade readiness check:

   <12.2.1.4_Oracle_Home>\oracle_common\upgrade\bin\ua.bat -readiness
   

   1. Select the Domain Based option and enter the domain location.
   2. Select the Include checks for all schemas and Include checks for all configurations check boxes.
2. Enter the WebLogic domain directory where schemas and configurations will be checked. This will be the path to the domains directory from <12.2.1.3_Oracle_Home>. For example, C:\Oracle\Middleware\Oracle_Home\user_projects\domains\FRDomain.
3. Check schemas and configuration in FRDomain.

   Schemas to be checked:

   • Oracle Platform Security Services – OPSS
   • Oracle Audit Services – IAU
   • Common Infrastructure Services – STB
   • Oracle WebLogic Server - WLS_RUNTIME

   Configuration to be checked:

   • System Components Infrastructure
   • Oracle HTTP Server
   • Oracle JRF
   • Common Infrastructure Services
   • Oracle Forms Services
   • Oracle Reports Services
4. Check schemas and configuration in OPADomain.

   Schemas to be checked:

   • Oracle Platform Security Services – OPSS
   • Oracle Audit Services – IAU
   • Common Infrastructure Services – STB
   • Oracle WebLogic Server - WLS_RUNTIME

   Configuration to be checked:

   • System Components Infrastructure
   • Oracle HTTP Server
   • Oracle JRF
   • Common Infrastructure Services
   • Oracle Forms Services
5. Enter the administrator database account credentials for checking the RCU OPSS schema. The account need to have DBA privileges (can be system account).

   Note:

   Click Connect to make sure the credentials you entered are valid.
6. Enter the administrator database account credentials for checking account credentials for the RCU IAU and STB schemas. The account need to have DBA privileges (can be system account).
7. In the Readiness Progress screen, check that all the components should have a green status – upgrade not necessary or ready for upgrade.

For OPADomain in the Readiness Progress screen all the components should have a green status – upgrade not necessary or ready for upgrade; except for Oracle Forms Services. The Oracle Forms Service component for OPADomain will be marked as Failure but this can be ignored as Oracle Forms Service is not a part of OPADomain.
