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.
- Log in as root.
- Navigate to the following directory: was_root/Uninstall_TWSS-Base
- 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.
- 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.
- 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.
- 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.
