Uninstalling the full product

Always use the uninstall wizard to remove this product, do not use the native uninstallation program.

The uninstallation process for the WebSphere Message Broker runtime and the Message Brokers Toolkit requires you to complete different actions. To uninstall the Message Brokers Toolkit, see Uninstalling the Message Brokers Toolkit. To uninstall the runtime components complete the following steps:

  1. Stop all running processes that use any part of WebSphere Message Broker (brokers, Configuration Manager and the User Name Server) before uninstalling. Use the mqsilist (list resources) command to check which components are running. Stop each component using the mqsistop command.
  2. On Windows and Linux (x86 platform), end any active sessions of the Message Brokers Toolkit.
  3. If you do not plan to reinstall on this computer, delete all the brokers (mqsideletebroker command), Configuration Managers (mqsideleteconfigmgr command), and User Name Servers (mqsideleteusernameserver command) that are associated with this installation. When you delete a component, all its associated data and resources are deleted; if you want to retain component data, do not delete that component.
  4. If you have created DB2 or Derby databases on Windows with the mqsicreatedb command, delete them with the mqsideletedb command. If you delete the last database, the Database Instance Manager is also deleted (the Database Instance Manager controls all appropriate databases in a single system; if you have another Version 6.0 installation, this component might not be deleted if databases associated with the other installation remain). Databases created by the Default Configuration wizard can also be deleted in this way.
  5. Use one of the following methods to invoke the uninstallation program. Only Windows users with one instance of the WebSphere Message Broker runtime installed should use the second method.
    • Run the following command from outside the installation directory, specifying the full path, this ensures that the folders are removed during uninstallation:
      /install_dir/_uninst_runtime/uninstaller
      Where install_dir is the home directory of your WebSphere Message Broker installation. If you accepted the default location during installation, this directory is as follows:
      • On Windows, C:\Program Files\IBM\MQSI\6.0
      • On AIX, HP-UX, and Solaris, /opt/IBM/mqsi/6.0
      • On Linux, /opt/ibm/mqsi/6.0
    • Navigate to Start > Settings > Control Panel > Add/Remove Programs. Select WebSphere Message Broker and click Change/Remove.
    The uninstaller is launched.
  6. Choose the component or components you wish to uninstall and follow the prompts to complete uninstallation.
