This task describes how to uninstall WebSphere Application Server - Express.
Before you begin
The uninstall command calls the uninstaller program that is created during installation. The uninstaller program is customized for each product installation, with specific disk locations and routines for removing installed features.
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 product.
Estimating the time required to uninstall The time required to uninstall is dependent on the processing speed of your machine. As a rough guideline, uninstalling the core product files and one application server profile takes approximately 10 minutes when using the uninstall command.
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.
Uninstalling WebSphere Application Server - Express
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.
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.
Result
This procedure results in uninstalling the product.
What to do next
After uninstalling the product and cleaning the system with the manual uninstall procedure, you can reinstall.
