Uninstalling Service Packs and Patches

At times you may want to uninstall a maintenance upgrade. You can use Smart Update to revert your system installation to an earlier version of the release, as described in the following sections:

 


Important Note about Uninstalling BEA Products

When you uninstall a BEA product, any patches that may have been applied to that product are not removed. This consideration is important if patches for multiple BEA products in a given BEA Home directory are applied to the same patch profile, and you uninstall one BEA product but continue to use the others. When this situation occurs, the BEA products that you continue using run with patches for the product that has been uninstalled.

If you have multiple BEA products installed in a single BEA Home directory, and you have a domain that exclusively uses only one of those BEA products, it is a recommended best practice to use custom patch profiles for that domain so that server instances run with only the patches that have been applied to the BEA products used by those servers. For information about pointing a domain at a custom patch profile, see Patching Individual Domains or Servers.

 


Removing a Patch or Patch Set

Smart Update makes it easy to remove a patch or patch set that has been applied to a patch profile. To remove a patch or patch set, complete the following steps:

  1. Start Smart Update.
  2. In the Target Installation pane, select the BEA product installation hosting the patch you want to remove.
  3. Select the Manage Patches tab.
  4. Select the patch profile containing the patch or patch set you want to remove.
  5. Click the Remove button with the down arrow, located to the right of the patch you want to remove.
  6. Remove button for a patch or patch set


     
  7. In the Remove Patch from Profile dialog, click OK.
  8. A validation dialog box is displayed. If you are removing one patch on which another depends, a removal conflict is reported, which you must resolve before proceeding. For information about resolving patch removal conflicts, see Validation When Removing Patches. The patch removal progress is tracked in the status window. A message is displayed when the removal is complete.

  9. Shut down any running WebLogic Server instances, and restart them for the patch removal to take effect.

Note: If you remove a patch that belongs to a patch set, the entry for the patch set is removed from the listing of the patch profile contents from the Downloaded Patches panel. However, other member patches of the set that have not been removed continue to be listed in those locations.

 


Uninstalling a Service Pack

Service packs to BEA products can be reverted; after installing a service pack to a product, such as WebLogic Server, you can revert to the previous service pack installation. For example, if you first install WebLogic Server 9.1, and then install Service Pack 1, you can later revert the installation to the initial release: WebLogic Server 9.1.

Notes: If you revert to an earlier service pack, user-created domains may stop working because of changes made in each domain's config.xml file between service packs. If you have a backup copy of each config.xml file used with the earlier service pack, you should use it after you revert the installation.

You cannot roll back to a previous version of a BEA product if that previous version was never installed on your machine.

  1. Start Smart Update.
  2. In the Target Installation pane:
    1. Select the BEA Home directory and installation containing the service pack you want to roll back.
    2. Service packs that you can uninstall (or roll back) are displayed in the Downgrade Options section of the window.

    3. In the Downgrade Options pane, select the service pack that you want to uninstall and click OK.
    4. The BEA Uninstaller Program opens and the Welcome window is displayed.

  3. Click Next to proceed.
  4. The progress of the uninstall process is reported in a status window. A message is displayed when the rollback or uninstallation is complete.

  5. Click Done on the status window.
  6. The Smart Update window is displayed. To close it, choose File—> Exit.
