$ STOP/QUEUE/MANAGER/CLUSTER

      The STOP/QUEUE/MANAGER/CLUSTER command in this example stops
      the queue manager process, SYS$QUEUE_MANAGER. The process
      remains stopped and requests to SYS$QUEUE_MANAGER will be
      denied until the START/QUEUE/MANAGER command is entered.

      This command stops the default queue manager SYS$QUEUE_MANAGER
      because the /NAME_OF_MANAGER qualifier is not specified.
