AIX: Uninstalling WebSphere Portal

If we have a complete and functional uninstallation program, we can uninstall IBM WebSphere Portal only or both WebSphere Portal and IBM WebSphere Application Server.

1. If we uninstall as a non-root user, verify that all product directories and files have the correct permissions. If not, set their permissions to the non-root user.

2. Stop all the servers.

3. Verify we are not running any other installation or uninstallation programs.

4. Choose one of the following uninstallation commands to uninstall WebSphere Portal and WebSphere Application Server:

   • Graphical user interface: Start the Installation Manager and then select Uninstall.

   • Response file: From the installation source directory, run the ./imcl input /path/to/response.xml -log pathtologfiles task.

     Do not place the response file in a path containing a space and do not put a space in the file name.

   • Console mode: Run the ./imcl -c task from the install_root/Installation Manager/eclipse/tools directory. Then, type 5.

     Restriction: We can select only one package group to uninstall at a time. First, uninstall the WebSphere Portal package. Then, uninstall the WAS package.

   During the uninstallation, remove all profiles that we do not want to keep for future installations.

5. Remove any remaining WebSphere Portal directories from the directory structure.

6. If we uninstall WebSphere Portal only, go to the APPSERVER_ROOT directory and remove the following files:

   • lib/ext/commons-codec-1.3.jar

   • lib/ext/commons-httpclient-3.0.1.jar

   • lib/ext/openid4java-full-0.9.5.jar

   • lib/ext/wp.auth.base.sua_RedirectServletFilter.jar

   • lib/ext/wp.auth.base.sua_loginmodule.jar

   • lib/ext/wp.auth.tai.jar

   • lib/wp.user.connections.jar

   • lib/wp.wire.jar

   • plugins/com.ibm.patch.was.plugin.jar

   • plugins/com.ibm.wp.was.plugin.jar

   • plugins/wp.ext.jar

   • properties/jndi.properties

7. Examine all running processes and stop ones containing the PortalServer_root directory. Restart the server, especially if you intend to reinstall WebSphere Portal on the same server.

8. Go to Delete specific cluster members for information about how to delete a cluster member from the deployment manager.

9. To delete the WebSphere Portal server from the deployment manager:

   1. Log on to the WAS console.

   2. Click Servers > Application Servers.

   3. Select the check box for the WebSphere Portal server to delete.

   4. Click Delete.

10. After uninstalling WebSphere Portal and WebSphere Application Server, we can also delete the Installation Manager. Run the ./uninstall command from the ibm/InstallationManager/uninstall directory.
