Uninstalling WebSphere MQ Server

If you are going to uninstall the WebSphere® MQ Explorer, see Uninstalling WebSphere MQ Explorer before uninstalling WebSphere MQ.

Before you uninstall WebSphere MQ, ensure that there are no WebSphere MQ programs or processes running. To do this:

  1. Stop WebSphere MQ. To do this right click the WebSphere MQ icon in the task bar, then select Stop WebSphere MQ.
  2. Close all WebSphere MQ windows.
  3. Stop any monitoring service.
There are three ways to uninstall WebSphere MQ from your machine:
  • Start the installation process, then select the appropriate option.
  • Use the Add/Remove Programs facility in the Windows® Control Panel.
  • Perform a removal from the command line.

You can use these methods to uninstall the WebSphere MQ server or the WebSphere MQ client, as long as the original installation used the WebSphere MQ Server CD (that is, not the WebSphere MQ Client CD).

You can also uninstall WebSphere MQ by using the appropriate parameters with Msiexec or MQParms, or by using Microsoft® System Management Server (SMS). See Uninstalling WebSphere MQ using the command line for more information about Msiexec.
