Uninstalling runtime components in silent mode

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

You can remove WebSphere Event Broker without user interaction. This process is called unattended (or silent) removal. This topic describes how to run the uninstallation program in silent mode without a response file; the program assumes all the default values.

If you want to complete a silent uninstallation, but have non-default requirements, you can use a response file. A response file is a text file that contains values for the options that you select when you uninstall WebSphere Event Broker. For more details of how to create, edit, and employ a response file to specify your requirements, see Using response files.

  1. Stop all running processes that use any part of WebSphere Event 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 of the runtime components. When you delete a component, all its associated data and resources are deleted. Use the following commands to do this: mqsideletebroker command, mqsideleteconfigmgr command, and mqsideleteusernameserver command.
  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. Run the uninstallation program using one of the commands below:
    • On Windows, run the command from inside the installation directory.
      start /w uninstaller
    • On Linux and UNIX, run the command from outside the installation directory to ensure that the folders are removed during uninstallation.
    Where install_dir is the home directory of your WebSphere Event 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
    The uninstallation program runs without interaction.
