DISABLE 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.
For more information on autostart queues, see the chapter on batch and
print queues in the HP OpenVMS System Manager's Manual.
Format
DISABLE AUTOSTART[/QUEUES]
Parameters
None.
Description
The DISABLE AUTOSTART/QUEUES command notifies the queue manager to
perform the following tasks on the affected node:
- Mark all of the queue manager's autostart queues as "stop
pending" in preparation for a planned shutdown.
- Prevent any of the queue manager's autostart queues from failing
over to the node.
- Upon completion of any jobs currently executing on any of that
queue manager's autostart queues, force the queue to fail over to the
next available node in the 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. Specify
the /ON_NODE qualifier to disable autostart on a different 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.
Qualifiers
/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 HP OpenVMS System Manager's Manual.
/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.)
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.
