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