1 ENABLE2 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 OpenVMS System Manager's Manual. Format ENABLE AUTOSTART[/QUEUES] 3 Qualifiers /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$QUEUE_MANAGER is used. For more information on multiple queue managers, see the chapter on the queue manager in the OpenVMS System Manager's Manual. /ON_NODE /ON_NODE=nodename Specifies a node in an OpenVMS Cluster system. Use this qualifier to enable autostart on a node other than the one from which you enter the command. /QUEUES Specifies that autostart is to be enabled for queues. (This qualifier is used by default.) 3 Examples 1.$ 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 fromthe 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.
