WebSphere brand IBM WebSphere Telecom Web Services Server, Version 7.1

Uninstalling Telecom Web Services Server base components silently

You can uninstall IBM® WebSphere® Telecom Web Services Server (TWSS) base components 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 which 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-Base
  3. Customize the response file you used to install the TWSS base components. For more information, refer to the topic Customizing the installation response file for Telecom Web Services Server base components.
  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 Telecom Web Services Server components. The script makes use of your customized response file. Issue the following command:
    ./setup -i silent -f response_file_path
    where response_file_path
    is the full path to your response file.
  6. Optional: Examine the uninstallation trace file at was_root/logs/TWSS-Services_Uninstall.log for any errors.
    Note: The uninstall process may not remove the TWSS-Services directory under the was_root/installableApps directory. You can manually remove the directory if you no longer need it.
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.
