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:.
