Setting Up and Managing Cluster Queues
7.5 Stopping the Queuing System
7.5 Stopping the Queuing System
When you enter the STOP/QUEUE/MANAGER/CLUSTER command, the queue
manager remains stopped, and requests for queuing are denied until you
enter the START/QUEUE/MANAGER command (without the /NEW_VERSION
qualifier).
The following command shows how to stop a queue manager named PRINT_
MANAGER:
$ STOP/QUEUE/MANAGER/CLUSTER/NAME_OF_MANAGER=PRINT_MANAGER
Rule: You must include the /CLUSTER qualifier on the command line whether
or not the queue manager is running on an OpenVMS Cluster system. If you
omit the /CLUSTER qualifier, the command stops all queues on the default node
without stopping the queue manager. (This has the same effect as entering the
STOP/QUEUE/ON_NODE command.)
7.6 Moving Queue Database Files
The files in the queue database can be relocated from the default location of
SYS$COMMON:[SYSEXE] to any disk that is mounted clusterwide or that is
accessible to the computers participating in the clusterwide queue scheme. For
example, you can enhance system performance by locating the database on a
shared disk that has a low level of activity.
7.6.1 Location Guidelines
The master file QMAN$MASTER can be in a location separate from the queue
and journal files, but the queue and journal files must be kept together in the
same directory. The queue and journal files for one queue manager can be
separate from those of other queue managers.
The directory you specify must be available to all nodes in the cluster. If the
directory specification is a concealed logical name, it must be defined identically
in the SYS$COMMON:SYLOGICALS.COM startup command procedure on every
node in the cluster.
Reference: The OpenVMS System Manager’s Manual contains complete
information about creating or relocating the queue database files. See also
Section 7.12 for a sample common procedure that sets up an OpenVMS Cluster
batch and print system.
7.7 Setting Up Print Queues
To establish print queues, you must determine the type of queue configuration
that best suits your OpenVMS Cluster system. You have several alternatives that
depend on the number and type of print devices you have on each computer and
on how you want print jobs to be processed. For example, you need to decide:
• Which print queues you want to establish on each computer
• Whether to set up any clusterwide generic queues to distribute print job
processing across the cluster
• Whether to set up autostart queues for availability or improved startup time
