$ HELP START /QUEUE /MANAGER /ON
In an OpenVMS Cluster, specify the nodes on which a clusterwide
queue manager can run. The default value for the node list is
the asterisk (*) wildcard character, meaning that all nodes in
the cluster are eligible to run the queue manager. If the node on
which the queue manager is running leaves the cluster, the queue
manager can automatically fail over to any available node in the
cluster. However, to specify a preferred order in which the nodes
should claim the queue manager, or to limit the nodes which can
run it, you must specify the /ON qualifier.
The node list you specify is stored in the queue database.
Anytime the START/QUEUE/MANAGER command is entered and neither
the /NEW_VERSION nor /ON qualifier is specified, the /ON list
stored in the queue database remains unchanged.
For highest availability, specify the asterisk (*) wildcard
character as the last node in the node list to indicate that
any remaining unlisted node can claim the queue manager, with
no preferred order. If you do not specify the asterisk (*)
wildcard character last in the node list, the queue manager can
only fail over if one of the nodes in the list is available.
However, if you want to exclude certain nodes from being eligible
to run the queue manager, you cannot use the asterisk (*)
wildcard character. You cannot specify the asterisk (*) wildcard
character as part of a node name.
Anytime the START/QUEUE/MANAGER command is entered (with or
without the /ON qualifier), the job controller will check to
see if one or more preferred queue manager nodes was currently
or previously specified with the /ON qualifier. If one or more
preferred nodes was specified, and the queue manager is running
on a node other than the first available node of those specified,
the queue manager process is moved from its current node and
restarted on the first available preferred node. Despite the
transition, queues on the running nodes are not stopped. All
requests to the queuing system, for example, PRINT, SUBMIT, and
SHOW ENTRY requests, will complete as expected.
