WebSphere

This information applies to feature pack. To use what is described, you must have installed the optional feature pack Uninstalling feature pack maintenance packages from Linux, UNIX, and Windows

You can use the IBM® Update Installer for WebSphere® Software to uninstall interim fixes and fix packs, collectively known as maintenance packages. On all platforms except i5/OS®, the Update Installer runs with a graphical user interface.

Before you begin
Procedure
  1. Log on to the operating system.

    For Linux operating systemFor UNIX operating system On Linux and UNIX platforms: In addition, verify that the umask setting is 0022.

    To verify the umask setting, type the following command: umask.

    To set the umask setting to 0022, type the following command: umask 0022

  2. Change directories to the Update Installer directory. The Update Installer directory is located in one of the following locations, depending on the operating system that you are using:
    • For AIX operating system On AIX® platforms: /usr/IBM/WebSphere/UpdateInstaller
    • For HP-UX operating systemFor Linux operating systemFor Solaris operating system On HP-UX, Linux and Solaris platforms: /opt/IBM/WebSphere/UpdateInstaller
    • For Windows operating system On Windows platforms: C:\Program Files\IBM\WebSphere\UpdateInstaller

    Uninstall the interim fix on each server node in a cell before uninstalling the maintenance package from the deployment manager node.

  3. Type the update command for your platform to start the Update Installer and click Next to exit the Welcome page.
    • For Windows operating system On Windows platforms: update.bat to uninstall the maintenance package with the most recent date stamp and time stamp using the graphical user interface.
    • Icon indicating Vista platformIcon indicating Windows 2008 platform On Vista and Windows 2008 platforms: update.exe to uninstall the maintenance package with the most recent date stamp and time stamp using the graphical user interface.
    • For Linux operating systemFor UNIX operating system On Linux and UNIX platforms: ./update.sh to uninstall the maintenance package with the most recent date stamp and time stamp using the graphical user interface.
    Important: Do not start multiple copies of the Update Installer at one time. Running more than one instance of the Update Installer at a time is not supported and can produce unpredictable results, which might include a failed or faulty update.
    For more information about the update command, see the update command topic in the WebSphere Application Server Network Deployment documentation.
  4. On the Product Selection page, select the installation of the feature pack that you want to update and click Next.
  5. On the Maintenance Operation Selection page, select to uninstall maintenance and click Next.
  6. On the Select the Maintenance Package to Uninstall page, select the interim fix or fix pack you want to uninstall and click Next.
  7. Review the Uninstallation Summary panel and click Next to begin the update.
  8. On the Uninstallation Complete page, click Finish to exit the Update Installer or Relaunch to add or remove additional maintenance packages.
Results
The Update Installer uninstalls the maintenance package and the Uninstallation Complete page indicates whether the completed update was successful. The Update Installer records uninstallation events in a log file in the following directory:
  • For AIX operating systemFor HP-UX operating systemFor Linux operating systemFor Solaris operating system feature_pack_install_root/logs/update/interim_fix_name or fixpack_name.uninstall/updatelog.txt
  • For Windows operating system feature_pack_install_root\logs\update\interim_fix_name or fixpack_name.uninstall\updatelog.txt

If errors are detected during the update, other messages might be displayed in place of Success. A message of Partial success indicates that the update completed but errors were generated. A message of Failed indicates that the update failed completely. In either case, the log file provides information to troubleshoot the problems.

Viewing the fix level of the node: You can use the versionInfo command in the feature_pack_install_root/bin directory to display the exact fix and version level of the product. However, do not use the versionInfo command while installing or uninstalling a maintenance package.

What to do next

If an interim fix involved one or more EAR files, the deployed EAR files will not be automatically downgraded. This is an extra manual step that is described in the interim fix readme file.

Any deployed feature pack enterprise applications (widget EARs) will not be uninstalled automatically. Each fix pack has documentation on how this should be handled.
