WebSphere brand IBM WebSphere Telecom Web Services Server, Version 7.1

Uninstalling theWeb service implementations silently

You can uninstall IBM® WebSphere® Telecom Web Services Server (TWSS) Web service implementations without user interactions. Instead, the uninstallation script uses a response file in which you supply options.

About this task

A silent uninstallation uses a script to uninstall the product in silent mode, without the graphical user interface. Instead of displaying a script interface, the uninstallation program reads all of your responses from the response file that you provide.

To specify non-default options during a silent uninstallation, customize the response file.

  1. Log in as root.
  2. Navigate to the following directory: was_root/Uninstall_TWSS-Services
  3. Customize the response file you used to install the TWSS Web service implementations. For more information, refer to the topic Customizing the installation response file for Telecom Web Services Server Web service implementations.
  4. Select a umask that allows the owner to read and write to the files, and that allows others to access them according to the prevailing system policy.
    Note: For root, a umask of 022 is recommended. For non-root users an umask of 002 or 022 can be used, depending on whether or not the users share the group.
  5. Invoke the uninstall script to uninstall TWSS components. The script makes use of your customized response file. Issue the following command:
    ./uninstall -silent -options full_path_to_response_file options
    where options can be any of the following:
    • -record file_name generates an optional uninstall record file named file_name. This file records the values and options that were selected during the interactive uninstallation and can be used for subsequent silent installations.
    • -is:log trace.log -log !trace.log @ALL produces a detailed log of the uninstall process. (Most installations will not require detailed logging.)
  6. Optional: Verify the uninstallation by checking to see that the directories that contained files for the TWSS components–for example, was_root/Uninstall_TWSS-Services– have been removed.
Results

Depending on the options selected, the uninstallation may take a while to complete. For example, it may take time for WebSphere Application Server to be stopped.

When the uninstallation has completed, check the appropriate logs in the was_root/logs directory. Refer to the topic Monitoring log messages for additional information about reading logs.
