Have you recently changed a password?

If you have changed the password at the operating system level for the user id that is used either as the ServiceUserId or the DataSourceUserId for any of the WebSphere Business Integration Message Broker components, this might cause a problem.

  1. Change the properties of the affected component to reflect the password change. Use the mqsichangebroker, mqsichangeconfigmgr, and mqsichangeusernameserver commands to change the properties of the WebSphere Business Integration Message Broker components.
  2. Make sure that your passwords do not contain reserved keywords. For example, IBM, which is a reserved keyword in DB2.
