Setting Up and Maintaining Queues
14.6 Using Queue Options
Example
You manage three LN03 printers in each of the four corners of a building. A
generic queue LN03$PRINT feeds execution queues for each printer. You can
define the characteristics EAST, WEST, NORTH, and SOUTH.
When a user submits a print job to LN03$PRINT with the EAST characteristic,
the job prints on the first idle LN03 printer in the eastern corner of the building.
If the system has queues for printers on multiple floors, you can further define a
characteristic for each floor, for example, FIRST, SECOND, and THIRD.
Commands for Specifying Queue Characteristic Options
Use the following commands when working with characteristics:
Command Description
DEFINE/CHARACTERISTIC Creates a characteristic and assigns a name
and number.
DELETE/CHARACTERISTIC Deletes a characteristic.
SHOW QUEUE/CHARACTERISTICS Displays information about characteristics
defined for the system.
INITIALIZE/QUEUE/CHARACTERISTICS
SET QUEUE/CHARACTERISTICS
START/QUEUE/CHARACTERISTICS
Specifies one or more characteristics for
processing jobs on a queue.
SHOW QUEUE/FULL Displays information about a queue, including
any characteristics assigned to the queue.
PRINT/CHARACTERISTICS
SUBMIT/CHARACTERISTICS
SET ENTRY/CHARACTERISTICS
Specifies the name or number of one or more
characteristics to be associated with the job.
The following sections describe how to specify queue characteristics.
14.6.3.1 Defining Characteristics
No characteristics are defined by default. To define a characteristic, use the
DEFINE/CHARACTERISTIC command in the following format:
DEFINE/CHARACTERISTIC characteristic-name characteristic-number
You cannot define more than one characteristic name to a number.
If your queue configuration requires more than one characteristic name for a
single number, you can define logical names to achieve the same result.
In an OpenVMS Cluster environment, you must define the logical names on every
node that requires them.
Note
If you want to define a characteristic name that is also an existing logical
name, read the description of logical names in the OpenVMS User’s
Manual.
