Uninstalling WebSphere Application Server

Perform the following steps to uninstall WebSphere Application Server from a UNIX machine:

  1. Ensure that you are logged into the machine with superuser (root) privileges.
  2. If IBM HTTP Server or another Web server is running on your system, stop the Web server.

    Note: Although IBM HTTP Server can be installed using the WebSphere Application Server installation program, it is not uninstalled when you uninstall WebSphere Application Server. It must be uninstalled separately. See the IBM HTTP Server Library Web site at www.ibm.com/software/webservers/httpservers/library.html for more information.

  3. Ensure that your DISPLAY and TERM environment variables are set properly.
  4. Navigate to the root installation directory (/opt/WebSphere/AppServer on HP-UX, Linux, and Solaris; /usr/WebSphere/AppServer on AIX) and execute the uninstall.sh script as follows:
    # ./uninstall.sh
  5. The uninstallation program starts and the Uninstall dialog box opens. Click Uninstall to remove WebSphere Application Server from the machine.
  6. To ensure that subsequent installations of WebSphere Application Server do not conflict with files left on the machine from a previous installation, use the rm -r command to remove the WebSphere directory structure. Use caution when executing this command to prevent the unintentional removal of portions of the file system.
