This task describes using the uninstaller program to uninstall WebSphere Application Server - Express.
Before you begin
The uninstaller program removes registry entries, uninstalls the product, and removes all related features. The uninstaller program does not remove log files in the installation root directory.
The uninstaller program removes all profiles, including all of the configuration data and applications in each profile. Before you start the uninstall procedure, back up the config folder, the installableApps folder, and the installedApps folder of each profile, if necessary. See Using command line tools for a description of managing configuration files. Back up all applications that are not stored in another location.
Why and when to perform this task
This procedure uninstalls the WebSphere Application Server - Express product.
Steps for this task
If a Web server is configured to run with the Application Server, uninstall the plug-ins to remove the configuration from the Web server. See Uninstalling the Web server plug-ins for WebSphere Application Server.
./stopServer.sh server1
./stopServer.sh server1 -user user_ID -password password
The uninstaller program does not remove log files in the installation root directory. The uninstaller program removes all profiles and all of the data in all profiles.
Back up the config folder and the logs folder of each profile to refer to it later, if necessary. You cannot reuse profiles so there is no need to back up an entire profile.
The command file is named uninstall for Linux and UNIX platforms and uninstall.exe on Windows platforms.
./uninstall
install_root\_uninst\uninstall.exe
C:\IBM\WebSphere\AppServer\_uninst> uninstall.exe
The Uninstaller wizard begins and displays the Welcome panel.
The rest of this procedure describes using the wizard interactively. You can also issue the uninstall command with a silent parameter to use the wizard without the graphical user interface.
uninstall -silent
The Uninstaller wizard displays a confirmation panel that lists the product and features that you are uninstalling.
The Uninstaller wizard deletes existing profiles first. For this reason, back up any profiles or data in profiles that you want to retain before uninstalling the product.
After deleting profiles, the Uninstaller wizard deletes the core product files in component order.
Result
This procedure uninstalls the WebSphere Application Server - Express product.
After running the uninstall command, the directory structure has only a few remaining directories. The logs directory is one of the few directories with files.
What to do next
If you plan to reinstall, perform the manual uninstall procedure for your system.
The uninstaller program leaves some log files, including the install_root/logs/uninstlog.txt file.
Manually uninstall the product to remove all artifacts of the product so that you can reinstall into the same installation root directory. If you do not plan to reinstall, you do not need to manually uninstall.
See Uninstalling manually for more information.
