Library /sys$common/syshlp/helplib.hlb  —  ENABLE

1  –  AUTOSTART 

    Enables the autostart feature on a node for all autostart queues
    managed by the specified queue manager. By default, this command
    uses the /QUEUES qualifier.

    Requires OPER (operator) privileges.

    Use this command to automatically start on the node all active
    autostart queues that are capable of executing on or that fail
    over to the specified node. By default, this command affects the
    node from which it is entered. Specify the /ON_NODE qualifier to
    enable autostart on a different node.

    For more information on autostart queues, see the chapter on
    batch and print queues in the VSI OpenVMS System Manager's Manual.

1.1  –  Qualifiers

1.1.1    /NAME_OF_MANAGER 

       /NAME_OF_MANAGER=name

    Specifies the name of the queue manager controlling the autostart
    queues you want to enable. The qualifier allows the autostart
    feature to be used differently for different sets of queues.

    If the /NAME_OF_MANAGER qualifier is omitted, the default queue
    manager name SYS$QUEUE_MANAGER is used.

    For more information on multiple queue managers, see the chapter
    on the queue manager in the VSI OpenVMS System Manager's Manual.

1.1.2    /ON_NODE 

       /ON_NODE=nodename

    Specifies a node in an OpenVMS Cluster system. Use this qualifier
    to enable autostart on a node other than the one from which you
    enter the command.

1.1.3    /QUEUES 

    Specifies that autostart is to be enabled for queues. (This
    qualifier is used by default.)

1.2  –  Examples 

    1.$ INITIALIZE/QUEUE/BATCH/START-
      _$ /AUTOSTART_ON=SATURN:: BATCH_1
      $ ENABLE AUTOSTART/QUEUES
         .
         .
         .
      $ DISABLE AUTOSTART/QUEUES

      In this example, the INITIALIZE/QUEUE command creates an
      autostart queue BATCH_1, capable of running on node SATURN.
      The /START qualifier activates the queue for autostart. The
      ENABLE/AUTOSTART/QUEUES command (executed on node SATURN)
      enables autostart on the node, causing the queue (and any other
      active autostart queues on the node) to begin executing jobs.

      The DISABLE AUTOSTART command (executed on node SATURN) stops
      autostart queues on the node and prevents any queues from
      failing over to the node.

      These commands only affect queues managed by the default
      queue manager SYS$QUEUE_MANAGER because the /NAME_OF_MANAGER
      qualifier is not specified.

      Because BATCH_1 is set up to run only on one node, the queue
      cannot fail over to another node and therefore is stopped;
      however, the queue remains active for autostart and will
      be started when the ENABLE AUTOSTART command is entered for
      node SATURN. No START/QUEUE command is needed to restart
      BATCH_1 unless autostart of the queue is deactivated with the
      STOP/QUEUE/NEXT or STOP/QUEUE/RESET command.

    2.$ INITIALIZE/QUEUE/BATCH/START-
      _$ /AUTOSTART_ON=(NEPTUN::,SATURN::) BATCH_1
      $ ENABLE AUTOSTART/QUEUES/ON_NODE=NEPTUN
      $ ENABLE AUTOSTART/QUEUES/ON_NODE=SATURN
         .
         .
         .
      $ STOP/QUEUES/ON_NODE=NEPTUN

      In this example, the INITIALIZE/QUEUE command creates an
      autostart queue BATCH_1. The /START qualifier activates the
      queue for autostart.

      The first ENABLE AUTOSTART/QUEUES command causes the queue
      to begin executing on node NEPTUN. The second ENABLE
      AUTOSTART/QUEUES command enables autostart on node SATURN to
      start all stopped active autostart queues on that node and to
      start any autostart queues that might fail over to that node.

      Later, suppose node NEPTUN must be removed from the OpenVMS
      Cluster system. The STOP/QUEUES/ON_NODE command stops all
      queues on node NEPTUN, and causes the autostart queue BATCH_
      1 to fail over to node SATURN. Because the queue is active
      for autostart, and because autostart has been enabled on node
      SATURN, the queue is automatically started on that node.

      This command only affects queues managed by the default
      queue manager SYS$QUEUE_MANAGER because the /NAME_OF_MANAGER
      qualifier is not specified.
