Examples

   1.$ START/QUEUE/MANAGER/NEW_VERSION
     $ SHOW QUEUE
     %JBC-E-NOSUCHQUE, no such queue

     The START/QUEUE/MANAGER command in this example starts the
     queue manager and creates the queue and journal files in the
     default location, SYS$COMMON:[SYSEXE]. Because the asterisk
     (*)  wildcard character is used by default as the value for the
     list of nodes on which the queue manager can run, the queue
     manager can fail over to any available node in the cluster.

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

     Both the SYS$COMMON:[SYSEXE] location and the value for the
     /ON qualifier (which is * by default in this example) are
     stored in the queue database for future reference. The newly
     created queue database contains no queues or jobs. The SHOW
     QUEUE command shows that no queues are defined on this cluster.

   2.$ START/QUEUE/MANAGER/NEW_VERSION -
     _$ /ON=(SATURN,VENUS,NEPTUN,*) DUA5:[SYSQUE]

     The START/QUEUE/MANAGER command in this example creates the
     queue and journal files on the cluster-accessible disk volume
     DUA5, in directory SYSQUE. You must mount the disk before you
     enter the START/QUEUE/MANAGER command.

     The /ON qualifier specifies that the queue manager should run
     first on node SATURN. If SATURN leaves the cluster, the queue
     manager will attempt to fail over to VENUS. If VENUS is not
     available, the queue manager will attempt to fail over to
     NEPTUN. If NEPTUN is not available, the queue manager will
     fail over to any other available node in the cluster.

   3.$ START/QUEUE/MANAGER/NEW_VERSION -
     _$ /ON=(SATURN,VENUS,NEPTUN,*) DUA5:[SYSQUE])
        .
        .
        .
     $ START/QUEUE/MANAGER

     The START/QUEUE/MANAGER command in this example creates the
     queue database as shown in the previous example. Suppose the
     queue manager started on node SATURN.

     Later, SATURN is removed from the cluster, and the queue
     manager fails over to node VENUS. When SATURN rejoins the
     cluster, the second START/QUEUE/MANAGER command in the example
     is entered to move the queue manager back to node SATURN.

     The second START/QUEUE/MANAGER command does not specify the
     DUA5:[SYSQUE] parameter value or the /ON qualifier and its node
     list because those previously supplied pieces of information
     are stored in the queue database. The queue manager continues
     to use the queue and journal files found at the location
     stored in its database. The /ON list, stored as a result of the
     previous START/QUEUE/MANAGER command, also remains unchanged.

   4.$ START/QUEUE/MANAGER DUA4:[SYSQUE]
     %JBC-E-QMANNOTSTARTED, queue manager could not be started
     $ SEARCH SYS$MANAGER:OPERATOR.LOG /WINDOW=5 QUEUE_MANAGE,JOB_CONTROL
     %%%%%%%%%%%  OPCOM  14-DEC-2001 18:55:18.23  %%%%%%%%%%%
     Message from user QUEUE_MANAGE on QMUNGR
     %QMAN-E-OPENERR, error opening DUA4:[SYSQUE]SYS$QUEUE_MANAGER.QMAN$QUEUES;

     %%%%%%%%%%%  OPCOM  14-DEC-2001 18:55:18.29  %%%%%%%%%%%
     Message from user QUEUE_MANAGE on QMUNGR
     -RMS-F-DEV, error in device name or inappropriate device type for
	operation

     %%%%%%%%%%%  OPCOM  14-DEC-2001 18:55:18.31  %%%%%%%%%%%
     Message from user QUEUE_MANAGE on QMUNGR
     -SYSTEM-W-NOSUCHDEV, no such device available
     $ START/QUEUE/MANAGER DUA5:[SYSQUE]

     In this example, the first START/QUEUE/MANAGER command
     specifies device DUA4: as the location of the queue and journal
     files. The error message indicates that the queue manager does
     not start. The SEARCH command searches the operator log file
     for relevant messages, and reveals that device DUA4: does not
     exist. The second START/QUEUE/MANAGER command specifies the
     correct device name, DUA5:.
