Manually uninstalling on HP-UX systems

This procedure uninstalls a WebSphere® Application Server product from an HP-UX system. After running the uninstaller program, manual steps remove log files and registry entries that can prevent you from reinstalling the product into the original directory. If you are not planning to reinstall, do not uninstall manually.

Before you begin

The uninstaller program removes all profiles by default, including all of the configuration data and applications in each profile. Before you start the uninstall procedure, back up the config folder, the installableApps folder, and the installedApps folder of each profile, if necessary, or use the -OPT removeProfilesOnUninstall="false" parameter on the uninstall command.See Using command line tools for a description of managing configuration files. Back up all applications that are not stored in another location.

Determine the installation root directory for the product so that you remove the correct product and produce a clean system.

About this task

Reinstalling the product into a new directory when files remain from a previous installation can create a coexistence scenario. However, you can delete all files and registry entries to completely remove a WebSphere Application Server product. A clean system lets you reinstall the product into the original directory without coexistence.

Table 1. Default directories.

Default directories are shown in the following planning table:

Identifier Directory Actual location
app_server_root /opt/IBM/WebSphere/AppServer  
profile_root /opt/IBM/WebSphere/AppServer/profiles  
plugins_root /opt/IBM/WebSphere/Plugins  

The installation wizard and the Profile Management Tool provide an override for your own locations for root directories.

Use the installRegistryUtils command that is located on the product disk to examine the installation locations for all installed WebSphere Application Server products.

Perform the following procedure to produce a clean system.

Procedure

  1. Log on as the same user ID who installed the product.
  2. Run the uninstaller program for the Web server plug-ins for WebSphere Application Server.

    If a Web server is configured to run with the application server, uninstall the plug-ins to remove the configuration from the Web server.

  3. Use the kill command to kill all Java™ processes that are running.
    If running Java processes are not related to WebSphere Application Server products and it is not possible to stop them, stop all WebSphere Application Server product-related processes. Use the following command to determine all processes that are running:
    ps -ef | grep java
    Stop all WebSphere Application Server-related processes with thekill command.
    kill -9 java_pid_1 java_pid_2...java_pid_n
  4. Issue the uninstall command.

    If you have already run the uninstaller program or if you cannot run the uninstaller program, skip this step.

    See the description of the uninstall command for more information.

    The Uninstaller wizard begins and displays the Welcome panel.

  5. Use HP-UX System Administration Manager (SAM) to remove packages.
    1. Start the SAM utility with the /usr/sbin/sam command.
    2. Verify that your DISPLAY and TERM environment variables are set properly.
    3. Click Software management.
    4. Click View installed software.
    5. Look for WebSphere Application Server entries or IBM® HTTP Server entries in the SD list.
    6. Close the SD list.
    7. Click Remove local host software.
    8. Click any of the following instances that display in the SD Remove List:
      • IBM HTTP Server
      • WSBAA70
      • WSPAA70
      • WSCAA
      • gsk7bas
    9. Click Actions > Mark for remove.
    10. Click Actions > Remove.
    11. Click OK in the Remove analysis dialog box.
    12. Click Logs to display real-time removal of selected packages.
    13. Click Done when all packages are removed.
    14. Exit SAM.
  6. Search for the packages to verify their removal.

    Type swlist | grep WS to show packages for WebSphere Application Server.

    Package names for Web server plug-ins for WebSphere Application Server are:

    WSPAA70 
    WSPAA70DGCC 
    WSPAA70DLVC 
    WSPAA70LC 
    WSPAA70WSPC 
    WSPAA70AddBytesHS
    WSPAA70gskitHP
    WSPAA70gskitHPC
    WSPAA70jdkHP
  7. Type rm -rf app_server_root to remove WebSphere Application Server directories in the app_server_root directory. Do not remove installation root directories for products that you intend to keep. Remove all of the profile directories as well.
  8. Use the installRegistryUtils command that is located on the product disk to examine the installation locations for all installed WebSphere Application Server products and remove the desired products from the install registry.

Results

This procedure results in having a clean system. You can reinstall into the same directories now. A clean system has no trace of a previously deleted installation.

Example

Issue the following command:

swlist | grep WSBAA70

The following package name is returned:

WSBAA70        7.0.0      IBM WebSphere Application Server
