12 Post-Upgrade Considerations

This chapter discusses the importance of a post-upgrade system test and considerations for the source Oracle home after the upgrade.

12.1 Starting the OracleAS Instance

Follow the steps below to start a middle-tier instance. If the middle-tier instance uses Infrastructure services, such as Identity Management or a Metadata Repository, make sure they are started.

  1. Start the components with this command:

    <destination_MT_OH>/opmn/bin/opmnctl startall

    OPMN and all OPMN-managed processes such as DCM, Oracle HTTP Server, OC4J instances, Web Cache, Forms, and Reports, are started.

  2. Start the Application Server Control Console with this command:

    <destination_MT_OH>/bin/emctl start iasconsole

12.2 Verify Operation of Middle Tier Components

Follow these steps to verify that the middle tier components that were upgraded are started:

  1. In a browser, access the Oracle Enterprise Manager Application Server Control in the 10g (9.0.4) middle tier Oracle home by entering its URL. Ensure that you provide the correct host name and port number. For example:

    http://midtierhost.mycompany.com:1812

    The Oracle Enterprise Manager 10g page appears. A link for the middle tier instance appears in the Standalone Instances section.

  2. Click the link.

    The System Components page appears.

  3. Verify that the components are running.

  4. Verify that the configuration information for the components in use is reflected in the 10g (9.0.4) Oracle home.

12.3 Check Significant URLs

Follow these steps to verify that you can access the Oracle HTTP Server and application URLs:

  1. Verify that you can access the Oracle HTTP Server on the same host and port that you did in the previous release by entering the URL. Ensure that you provide the correct host name and port number. For example:

    http://midtierhost.mycompany.com:7777

  2. Verify that you can access the URLs for the applications you operated in the previous release, and ensure that the applications are functioning as they did in the previous release.

12.4 Performing a System Test

After the upgrade, you should perform tests for all applications in the upgraded instance to validate the correct functioning and interdependence of all components in the middle tier. If you use Infrastructure services, perform tests to ensure that they are working as expected.

12.5 Decommissioning the Source Oracle Home

When you are certain that the upgrade was successful, you have all of the necessary backups, and have no plans to revert to the source Oracle home, you may elect to remove the files from the source Oracle home. Use the Oracle Universal Installer to deinstall the instance.

12.5.1 Preserving Application Files and Log Files

If there are application files or log files in the source Oracle home that are being referenced or used by the destination Oracle home, you should move them to another location before you decommission the source Oracle home, and, in the destination Oracle home, change any references to the files to the new location.
