Uninstalling base WebSphere Application Server

This task describes using the uninstaller program to uninstall WebSphere Application Server.

Before you begin

Before uninstalling, verify that you have no open Web browsers that are accessing the administrative console.

Uninstalling products in the proper order Depending on the WebSphere Application Server products you installed, uninstall all that you intend to uninstall in this order:

  1. [5.0 only][Version 5.0.1][Version 5.0.2]WebSphere Application Server Enterprise
  2. WebSphere Application Server Network Deployment
  3. WebSphere Application Server (base product)

Steps for this task

  1. Stop any browsers, delete any configuration instances, and stop any Java processes related to WebSphere Application Server products as described in Uninstalling the product.
  2. Change directories to the _uninst directory before issuing the uninstall command.
    The command file is located in the install_root/_uninst directory on a Linux or UNIX-based platform, and in the install_root\_uninst directory on a Windows system.

    For example, to change directories on a Linux platform, issue this command if your installation root is /opt/WebSphere/AppServer:

    cd /opt/WebSphere/AppServer/_uninst
    

  3. Issue the uninstall command.
    The command file is named uninstall for Linux and UNIX-based platforms and Uninstall.exe on Windows platforms. The command file for V5.0.x on Linux for S/390 platforms* is named uninstall.sh. For V5.1 the command file is named uninstall, as it is on other Linux platforms.

    *Linux for S/390 platforms refers to the Linux distributions available from Linux distributors that run on IBM eServer zSeries and S/390 systems in 31-bit mode.

    On Windows platforms, call the Uninstall.exe command:

    install_root\_uninst\Uninstall.exe
    Call the program directly from the install_root\_uninst directory. For example, if the installation root is C:\WebSphere\AppServer, issue the following command:
    C:\WebSphere\AppServer\_uninst> Uninstall.exe

    On Linux and UNIX-based platforms, issue the uninstall command from the install_root/_uninst directory:

    uninstall
    (To uninstall V5.0.x on a Linux for S/390 platform, use the uninstall.sh script.)

    Uninstalling the product also selects the feature uninstaller programs, such as the uninstaller program for the plug-ins feature.

    The V5.1 uninstaller wizard prompts you whether to uninstall the embedded messaging feature when the feature is present. To obey licensing rules, always remove the embedded messaging feature unless there are other product instances on the machine that also share the code. The V5.0.x uninstaller program does not have this enhancement of leaving the embedded messaging feature code installed. Therefore, the procedure for uninstalling WebSphere Application Server varies slightly, depending on the version you are uninstalling.

    The uninstaller wizard begins and displays a panel.

    In V5.0.x the uninstaller program displays a language selection panel.

  4. Click Next to begin uninstalling the product.
    In situations where the embedded messaging feature is installed, the V5.1 uninstaller wizard displays the panel that prompts you whether to uninstall the embedded messaging feature. Click Next on that panel to continue uninstalling the product.
    The uninstaller wizard displays a summary panel that lists the product and features that you are uninstalling.
  5. Click Next to continue uninstalling the product.
  6. Click Finish to close the wizard after the wizard removes the product.

Results

You can uninstall WebSphere Application Server.
