This topic describes the proper procedure for using the update installer application to uninstall an interim fix, a cumulative fix, or a fix pack from an application server node. The update installer program is also known as the updateInstaller program or the Update installation wizard.
Before you begin
The update installer program removes interim fixes, cumulative fixes, and fix packs from WebSphere Application Server products, including base application server nodes.
Why and when to perform this task
This procedure describes a scenario for updating a base node by removing an interim fix, a cumulative fix, or a fix pack. See Installing interim fixes, cumulative fixes, and fix packs to install an interim fix, a cumulative fix, or a fix pack.
Always uninstall the highest level interim fix, cumulative fix, or fix pack before uninstalling other interim fixes or fix packs.
Steps for this task
Windows systems:
Linux and UNIX systems:
Depending on the interface you use to the update installer:
For example, to uninstall the was50_fp2_win fix
pack, use this updateSilent command:
C:\WebSphere\AppServer\update> updateSilent -fixpack -installDir "C:\Program Files\WebSphere\AppServer" -skipIHS -fixpackDir "C:\WebSphere\AppServer\update\fixpacks" -uninstall -fixpackID was50_fp2_winThe command is shown here on more than one line, for clarity.
If you see the interim fix, the cumulative fix, or the fix pack in one of the panels, the fix is installed.
If you see the interim fix, the cumulative fix, or the fix pack in one of the panels, the fix is not installed.
Or, does one of the following files exist in the install_root/properties/version/history directory?
These types of files indicate the installation of a fix. See Product version and history information for more information.
See Product version and history information for more information about the reports.
See TARGET NOT FOUND FOR LOOKUP for more information.
See TARGET NOT FOUND FOR LOOKUP for more information.
The following platform-specific procedures for uninstalling each describe a manual process that guides you through removing every trace of the products and features you might have installed, including directories that might have changed data.
Before you begin one of the procedures, back up the config and properties directories in the installation root. Backing up the directories lets you refer to the changed data when you reinstall.
Results
You can successfully remove interim fixes, cumulative fixes, and fix packs from a base WebSphere Application Server node.
