Clean your Windows system after uninstalling the product

Uninstall a WAS product from a Windows system by running Installation Manager and then performing manual steps to remove log files and registry entries that can prevent you from reinstalling the product into the original directory. If you are not planning to reinstall, you do not have to clean the system.
The uninstallation program removes all profiles by default, including all of the configuration data and applications in each profile. Before you start the uninstallation procedure, back up the config folder, the installableApps folder, and the installedApps folder of each profile if necessary.

Determine the installation root directory for the product so that you remove the correct product and produce a clean system.

Reinstalling the product into a new directory when files remain from a previous installation can create a coexistence scenario. However, you can delete all files and registry entries to completely remove a WAS product. A clean system lets you reinstall the product into the original directory without coexistence.

Default directories.

Default directories are shown in the following planning table:

Identifier Default Directory
WAS_HOME C:\IBM\WebSphere\AppServer
PROFILE_ROOT C:\IBM\WebSphere\AppServer\profiles
plugins_root C:\IBM\WebSphere\Plugins

Installation Manager and the Profile Management Tool provide an override for your own locations for root directories.

Perform the following procedure to produce a clean system.


Procedure

  1. Log on with the same user ID that was used to install the product.

  2. Use Installation Manager to uninstall the Web Server Plug-ins.

    If a web server is configured to run with the application server, uninstall the plug-ins to remove the configuration from the web server.

  3. Stop any browsers and any Java processes related to WAS products.
  4. Remove the application server service from the operating system.

    Stop the IBM WAS V8.0 - nodename service using the Windows Services panel, or run the WASService -stop command located in...

    WAS_HOME/bin
    Then run the WASService -remove command to remove the service from the operating system.

  5. Use Installation Manager to uninstall the product.

  6. Delete the installation root directory for the product that you are uninstalling.
  7. Locate all of the profile directories and delete the directories if they were located outside of the WAS_HOME directory and were not deleted in the previous step.


Results

This procedure results in having a clean system. We can reinstall into the same directories now. A clean system has no trace of a previously deleted installation.
