Uninstalling manually

This task describes how to remove all artifacts of an instance of the product so that you have a clean machine with regard to the instance. Repeat the procedure for each instance of the product that you intend to remove.

Before you begin

Uninstalling manually occurs after running the uninstaller program, or because you cannot run the uninstaller program because the program might affect federated nodes, coexisting products, or features. The following for manually uninstalling the product are specific to the platform on which the product is installed.

Before uninstalling, verify that you have no open Web browsers that are accessing the administrative console. Otherwise, there is the potential for locked file errors as you uninstall.

Why and when to perform this task

Even if you run the uninstaller program to remove registry entries, uninstall the product code, and remove all related features and products, such as plug-ins, there are some files that the uninstaller program does not remove. The uninstaller program does not delete any configuration files that are changed as the result of selecting installation options, or running Samples, for example. The uninstaller program does not delete log files.

Steps for this task

  1. Stop any embedded messaging feature services, such as WebSphere Embedded Messaging Publish And Subscribe, jmsserver, or WebSphere MQ queue managers, and any related Java processes.
  2. Stop the IBM HTTP Server and any related Java processes.
  3. Stop any WebSphere Application Server Java processes with the stopManager or stopServer commands.
  4. Back up all configuration and log files.
    The uninstaller program leaves some log and configuration files that were changed during installation. Before manually uninstalling the product, copy all configuration and log files that are left behind in the WebSphere, the IBMHTTPServer, and the IBM/MQSeries directories.

    You can refer to your copy of the configuration and log files after you reinstall to compare the configuration data, if necessary.

  5. Use one of the following platform-specific uninstalling procedures to delete the directories that are left behind for your product instance, and to perform other tasks that let you reinstall the product on your operating system.
    You cannot reinstall into the old directories. Deleting the directories and registry entries lets you reinstall with a clean system. If you do plan to reinstall the product, it is important that you follow the procedure for your platform to completely remove all artifacts of the previous installation.
