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:
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.
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:
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.
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.
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.
