will be deleted from the MEDIA parameter file upon exiting the
configure program.
5.2.3 Types
The most common use for a type is to categorize physical devices into groups (CARTRIDGES, TAPES, DISKS etc.). You can also create types according to classifications such as user backups, system backups etc. and assign certain physical devices to those groupings. In order to create, display, add devices to, remove devices from or delete types choose Types from the MEDIA settings menu.
5.2.3.1 Create type

On a DECwindows workstation click on Confirm to delete the type from the MEDIA parameter file. Click on Dismiss to cancel the deletion.
5.2.4 Queues
Setting the queue parameter specifies which queue is to be used during
a job command to submit the specified medium for processing. The media
that is submitted into a queue is grouped using the type command.
Therefore, it is important to set up types before attempting to
configure the queue in which it is used. In order to create, display,
modify or delete a queue, choose Queues from the
MEDIA Settings menu.
The following table describes the fields from the form that appears when creating, modifying or displaying a queue.
| Field | Description |
|---|---|
| Queue name | This is the name used to identify the queue. |
| Node name | Name of node that the queue will operate on. Normally refers to the node specific device. |
| Base priority | Priority of queue relative to other queues currently running. Value can be 0 to 255. Base priority is strictly a VMS queue function and is not related to the parameter file. |
| Job limit | Number of executable jobs that can operate in a single queue. Value can be 0 to 16. Normal value is 4. Job limit is strictly a VMS queue function and is not related to the parameter file. |
| Types | A list of the types that are to be assigned to the queue. The maximum is 10 types to a queue. |
To create a new queue, choose Create from the Queue menu. A dialog box will appear into which the name of the queue to be created can be entered.
If the queue name has previously been entered a message will appear informing the user that the name is already being used. In this case a new name must be entered. After entering the queue name, the queue data form will appear.
In order to display data related to a queue, choose Display from the Queue menu. A menu will appear listing all current queues.
5.2.4.3 Modifying a queue
In order to modify the data related to a certain queue, select
Modify from the Queue menu. A menu
will appear listing all current queues.
After choosing the desired queue the following form will appear.
Figure 5-2 Queue data form
5.2.4.4 Deleting a queue
To permanently delete a queue, choose Delete from the
Queue menu. A menu will appear listing all current
queues. After choosing the desired queue, a confirmation message will
appear prompting to "confirm deletion of the queue. On a DECwindows
workstation click on Yes to delete the queue from the MEDIA
parameter file. Click on No to cancel the deletion.
5.2.5 Defaults
In order to set the defaults for add-on and catalog operations, temporary medium and selection controls, choose Defaults from the MEDIA Settings menu.
The purpose of setting the defaults is to have the most common data
already predefined when performing a procedure. This is a convenient
method of avoiding time consuming data entry when working with new
media.
5.2.6 Default tables
The following tables describe the fields which may be set to default
for the add and catalog operations as well as setting up temporary
medium. Note that very few are suited to be set to default values. For
instance you would not want to set a default value for the External ID
of a medium since this would mean all your media would have the same
External ID. Those fields that are suited for default values are in
bold type in the following tables.
5.2.7 Physical description fields
Table 5-1 lists all fields displayed when a user chooses to either modify or display a medium header and then chooses Physical description fields from the subsequent menu:
