Uninstalling the product on IBM i

You can uninstall a WebSphere® Application Server for IBM® i product by running commands from your iSeries® server.

Before you begin

The uninstaller for WebSphere Application Server is now able to detect other products which extend the application server and have claimed a dependency on the application server. If you have installed other products which extend the application server, then you will be unable to uninstall the application server before uninstalling the other products. Products which extend the application server are feature packs and other products which rely on the application server runtime environment.

Uninstall any products which extend the application server, such as feature packs or other products which rely on the application server runtime environment, before you attempt to uninstall the application server. You will be unable to uninstall the application server product without uninstalling the other products.

About this task

Use this procedure to uninstall WebSphere Application Server Network Deployment for IBM i.

Procedure

  1. Uninstall WebSphere Application Server Network Deployment for IBM i from your iSeries server.
    To uninstall the product, run the following command from the Qshell command line.
    app_server_root/bin/uninstall
    To uninstall the product and all user data (profiles), run the following command.
    app_server_root/bin/uninstall
       -OPT removeProfilesOnUninstall="true"
    After the uninstallation is complete, certain directories might not be completely removed. You must remove the product directory before you can reinstall to the same location. Do not remove installation root directories for products that you want to keep. To remove the product directory after uninstallation, run the following command.
    rm –R app_server_root
    Optional: Remove profiles and user data. Do not remove profiles and user data that you want to keep. To remove profiles and user data completely after uninstallation, run the command:
     rm –R profile_root

    Uninstalling WebSphere Application Server from the iSeries server removes all the product libraries and directories. If you do not specify the option to delete all the profiles when you invoke the uninstall command, the user-defined information is not removed and can be reused if you reinstall the product. If you later decide that you do not need the user-defined data, you can manually remove it.

    User data consists of these items:
    • All directories and files under the profile_root directory, which is the directory specified as the value for the profilePath parameter when creating the profile with the manageprofiles command. Manually delete any files or directories that you no longer need.
    • Any HTTP server directives (such as LoadModule or Alias) that are in an HTTP Server Configuration file to enable WebSphere Application Server Network Deployment for IBM i for that configuration. Remove the directives either manually or automatically using the following instructions.
  2. Remove HTTP Server directives.
    1. Start your JavaScript-enabled browser.
    2. In the URL location or address window, type http://your.server.name:2001, where your.server.name is the host name of your iSeries server. Press Enter.
    3. Enter your iSeries user ID and password. Your user profile must have *ALLOBJ and *SECADM special authorities. The IBM i Tasks page is displayed.
    4. Click IBM HTTP Server for IBM i. The IBM HTTP Server for IBM i page is displayed.
    5. Select Manage. In the Server drop-down list on the upper right, select the HTTP server instance to change.
    6. Expand Server Properties in the left navigation bar.
    7. Scroll down and select WebSphere Application Server.
    8. Select Disable Servlets and JSPs.
    9. Click OK. This removes the WebSphere Application Server directives from the Apache configuration file and returns to the main configuration page.
  3. Remove Lotus® Domino® Web server directives.
    1. From a Lotus Notes® client connected to the Domino server, edit the Domino document, which is found in the Domino server Domino Directory (names.nsf) to remove the DSAPI filter configuration from the Domino server document.
    2. Within the server document, click the Internet Protocols tab and then click the HTTP tab.
    3. Remove the following path entry from the DSAPI filter file names field: /QSYS.LIB/QWAS7.LIB/QSVTDOMINO.SRVPGM.
    4. Save and exit the Domino Server document to complete the removal of the DSAPI filter configuration from the Domino server document.
    5. Enter the Work with Domino Servers (WRKDOMSVR) command on a CL command line to remove the WebSphereInit directive from the notes.ini file.
    6. For the appropriate Domino server instance, select option 13 (Edit NOTES.INI) to edit the server notes.ini file.
    7. Remove the WebSphereInit directive from the notes.ini file.
    8. Restart the Lotus Domino Web server.

Results

After completing the procedure, the WebSphere Application Server product is uninstalled.
