Required synchronization with feature packs with the Update Installer

The Update Installer for WebSphere Software synchronizes versions of Application Server fix packs and fix packs for a feature pack.

A fix pack for an Application Server feature pack has a dependency on a specific version of the Application Server to function properly. This dependency might get out of synch when a later version of one of the components is applied. To avoid compatibility problems between different version levels, the Update Installer requires that all of the fix packs for the Application Server and fix packs for the feature pack be of the same version to be installed concurrently. The Update Installer enforces this synchronization during installation.

If you are applying maintenance to multiple applications, the Update Installer will allow you to select the packages that you want to install. However, if you have omitted any applications on your system that need to be updated to the latest level, the prerequisite checking logic will detect this, and the Update Installer will issue an error message. The Update Installer logic requires that you install all of the maintenance packages concurrently. In addition, the Update Installer will launch the Available Maintenance Package to Install panel that will allow you to select the appropriate packages to be updated.

The Update Installer provides a link to the Application Server support site, where the proper levels of maintenance for the Application Server and feature packs can be downloaded before you use the Update Installer to apply maintenance.

To avoid problems with compatible versions, download the latest Application Server fix pack and latest fix packs for the feature pack. After applying the updates, check the summary panel and log file to ensure that all of the updates were applied.

Synchronization and uninstalling maintenance

The Application Server fix packs and fix packs for the feature pack can get out of synchronization during uninstallation. The Update Installer can only uninstall one maintenance package at a time, so fix packs can get out of synch with other fix packs. In order to uninstall a fix pack, you must uninstall the fix pack in the reverse order that it was installed. Uninstall the most recently installed fix pack first. You are responsible for ensuring that the corresponding fix packs are removed properly in order to keep the Application Server fix packs and feature pack fix packs in synch.
