2 AUTOSTART
Disables the autostart feature on a node for all autostart queues
managed by the specific queue manager. By default, this command
uses the /QUEUES qualifier.
Requires OPER (operator) privileges.
Disabling autostart for queues notifies the queue manager to
perform the following tasks on the affected node:
o Mark all autostart queues as "stop pending" in preparation for
a planned shutdown.
o Prevent autostart queues from failing over to the node.
o Upon completion of any jobs currently executing on one of the
node's autostart queues, force the queue to fail over to the
next available node in a queue's failover list (if any) on
which autostart is enabled. (For information on failover lists
for autostart queues, see the /AUTOSTART_ON qualifier for the
INITIALIZE/QUEUE command.)
Autostart queues on the node that do not have a failover list, or
for which no failover node is enabled for autostart, are stopped
upon completion of any current jobs. These stopped queues remain
activated for autostart. The queue manager will restart these
stopped autostart queues when the ENABLE AUTOSTART command is
entered for the affected node or a node to which the queue can
fail over.
By default, the command affects the node on which it is entered.
Use the /ON_NODE qualifier to disable autostart on a different
node. On VAX systems by default, the command affects autostart
queues managed by the default queue manager, SYS$QUEUE_MANAGER.
Specify the /NAME_OF_MANAGER qualifier to disable autostart of a
different queue manager's autostart queues on the node.
The DISABLE AUTOSTART/QUEUES command is included in the node
shutdown command procedure SHUTDOWN.COM. If you shutdown a node
without using SHUTDOWN.COM, and the node is running autostart
queues, you might want to enter the DISABLE AUTOSTART/QUEUES
command first.
The DISABLE AUTOSTART/QUEUES command only affects autostart
queues.
For more information on autostart queues, see the chapter on
batch and print queues in the OpenVMS System Manager's Manual.
Format
DISABLE AUTOSTART[/QUEUES]
3 Qualifiers
/NAME_OF_MANAGER
/NAME_OF_MANAGER=name
Specifies the name of the queue manager controlling the autostart
queues you want to disable. The qualifier allows the autostart
feature to be used differently for different sets of queues.
If the /NAME_OF_MANAGER qualifier is omitted, the default queue
manager name SYS$QUEUE_MANAGER is used. For more information on
multiple queue managers, see the OpenVMS System Manager's Manual.
/ON_NODE
/ON_NODE=nodename
Specifies a node in an OpenVMS Cluster system. Use this qualifier
to disable autostart on a node other than the one from which you
enter the command.
/QUEUES
Specifies that autostart is to be disabled 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 executing 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.
This command only affects queues managed by the default
queue manager SYS$QUEUE_MANAGER because the /NAME_OF_MANAGER
qualifier is not specified.
Because BATCH_1 is set up to run only on one node, the queue
cannot fail over to another node and therefore is stopped.
However, the queue remains active for autostart and will be
started when the ENABLE AUTOSTART command is entered for node
SATURN. No START/QUEUE command is needed to restart BATCH_1
unless autostart of the queue is deactivated with the STOP
/QUEUE/NEXT or STOP/QUEUE/RESET command.
2.$ DISABLE AUTOSTART/QUEUES/ON_NODE=JADE
The DISABLE AUTOSTART/QUEUES command in this example disables
autostart on the OpenVMS Cluster node JADE. This command can be
entered from any node in the cluster.
