$ 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.
