Uninstall Application Client for WAS

Uninstall Application Client for WAS

This task describes using uninstall program to uninstall the Application Client for WAS.
To uninstall IBM Application Client for WAS manually, read the Manually uninstalling on a Windows system topic.
If we have a feature pack installed, uninstalling the Application Client for WAS using the V6.1.0 uninstaller program causes the feature pack to stop working because the uninstallation removes the server. However, we can uninstall the feature pack after uninstalling WAS v7.
If logged in as a root user and attempt to uninstall an instance of Application Client for WAS that a non-root user installed, the Windows registry will also be wiped clean for the application client instance that the root user installed. If we need to uninstall an instance of application client that a non-root user has installed, be sure that we are logged in as the non-root user.

(Windows)
To register an application on Windows operating system, be registered in the administrator group. If we install Application Client and we are not a member of the administrator group, the Windows registration will not register the installer in the Windows registry. Consequently, there will not be an entry for Application Client in the Add or Remove Programs window.

Next steps
Verify the uninstall procedure by viewing the APP_ROOT/logs/uninstall/log.txt file for errors. Look for the INSTCONFSUCCESS, indicating a successful uninstall in the log file:
Uninstall, com.ibm.ws.install.ni.ismp.actions.ISMPLogSuccessMessageAction, msg1, INSTCONFSUCCESS

The uninstallation wizard records uninstallation events in the uninstallation log files. Examine messages that the uninstallation program displays. If the Application Client for WAS does not uninstall successfully, read the messages to identify why the uninstallation failed. Correct the problems identified and try uninstalling WAS again.
Tip: If logged in as non-root or non-admin user, the uninstall may not be successful. When the uninstaller program runs, a log file is created in the home directory. If the uninstaller program fails, an attempt is made to move the log to the APP_ROOT directory; however, without the necessary permission to move the file to the APP_ROOT directory, the attempt to move fails and the log remains in the home directory. Look for the following log files in the user_home/waslogs directory:

log.txt
trace.txt.gz
trace.xml.gz
