INITIALIZE/QUEUE

Creates or initializes queues. You use this command to create queues and to assign them names and options. The /BATCH qualifier is required to create a batch queue.

Requires OPER (operator) privilege to create queues and manage (M) access to modify queues.

Format

INITIALIZE/QUEUE queue-name[:]

Parameter

queue-name[:]

Specifies the name of an execution queue or a generic queue. The queue name may be a string of 1 to 31 characters. The character string can include any uppercase and lowercase letters, digits, the dollar sign ($), and the underscore (_), and must include at least one alphabetic character.

Description

Use the INITIALIZE/QUEUE command to create a queue or to change the options of an existing queue that is stopped.

Normally you create output and batch queues by entering the necessary INITIALIZE/QUEUE commands when you set up your system or OpenVMS Cluster. Later, you can use the INITIALIZE/QUEUE command to create additional queues as they are needed. When you create a queue with the INITIALIZE/QUEUE command, information about the queue is stored in the queue database.

To create and start the queue at the same time, you can use the INITIALIZE/QUEUE/START command. If you want to create the queue only and start it at another time, you can enter only the INITIALIZE/QUEUE command. Later you can enter the START/QUEUE command to begin queue operations.

You can use the INITIALIZE/QUEUE, START/QUEUE, and SET QUEUE commands to change queue options; as you change queue options, information about the queue in the queue database is updated.

You can use the INITIALIZE and START commands only on stopped queues. To change options on a running queue, use the SET QUEUE command. To change queue options that cannot be altered with the SET QUEUE command, use the following procedure:

  1. Stop the queue with the STOP/QUEUE/NEXT command.
  2. Restart the queue with the START/QUEUE or the INITIALIZE/QUEUE/START command, specifying the appropriate qualifiers for the options you desire.
    Any qualifiers that you do not specify remain as they were when the queue was previously initialized, started, or set.

Note that initializing an existing queue does not delete any current jobs in that queue. Any new queue settings established by the new INITIALIZE/QUEUE command affect all jobs waiting in the queue or subsequently entering the queue. Any jobs that are executing in the queue when it is stopped complete their execution under the old settings.

The following qualifiers apply to generic and execution queues:

/OWNER_UIC
/PROTECTION
/[NO]RETAIN
/[NO]START
/NAME_OF_MANAGER

The following qualifiers apply to all types of execution queues:

/AUTOSTART_ON
/BASE_PRIORITY
/[NO]CHARACTERISTICS
/[NO]ENABLE_GENERIC
/[NO]NO_INITIAL_FF
/ON
/WSDEFAULT
/WSEXTENT
/WSQUOTA

The following qualifiers apply only to batch execution queues:

/CPUDEFAULT
/CPUMAXIMUM
/[NO]DISABLE_SWAPPING
/JOB_LIMIT

The following qualifiers apply only to printer, terminal, or server execution queues:

/[NO]BLOCK_LIMIT
/[NO]DEFAULT
/FORM_MOUNTED
/[NO]LIBRARY
/[NO]PROCESSOR
/[NO]RECORD_BLOCKING
/[NO]SEPARATE

Types of Queues

There are several different types of queues. In general, queues can be divided into two major classes: generic and execution. When a job is sent to an execution queue, it is executed in that queue. No processing takes place in generic queues. Generic queues hold jobs that will execute on an execution queue.

Generic Queues

The following are several types of generic queues:

The /GENERIC qualifier designates a queue as a generic queue. You specify the execution queues to which a generic queue feeds jobs in one of two ways:

Generic queues, unlike execution queues, are not automatically stopped when the system is shut down or the queue manager is stopped; therefore, generic queues do not normally need to be restarted each time the system reboots.

Logical Queues

Another type of queue is the logical queue. A logical queue is a special type of generic queue that can place work only into the execution queue specified in the ASSIGN/QUEUE command. The logical queue's relation to an execution queue remains in effect until you enter a DEASSIGN/QUEUE command to negate the assignment.

Execution Queues

The following are several types of execution queues:

Batch execution queues execute batch jobs. Batch jobs request the execution of one or more command procedures in a batch process.

Output execution queues process print jobs. A print job requests the processing of one or more files by a symbiont executing in a symbiont process. The default system symbiont is designed to print files on hardcopy devices (printers or terminals). Customer-written symbionts can be designed for this or any other file processing activity. Server queues process jobs using the server symbiont specified with the /PROCESSOR qualifier. Server queue symbionts are written by the customer.

Either the /AUTOSTART_ON qualifier or the /ON qualifier designates a queue as an execution queue, and specifies where the queue is to run.

By using the /ON qualifier, you can specify one node (for batch queues) or node and device (for output queues) on which the queue can be started. A queue initialized with the /ON qualifier needs to be started by a command explicitly naming the queue.

You can specify one or more nodes (or nodes and devices) on which the queue can be started by using the /AUTOSTART_ON qualifier. A queue initialized with the /AUTOSTART_ON qualifier is automatically started by the queue manager when any of the queue's nodes have been enabled for autostart by that queue manager.

Autostart Queues

An execution queue (either batch or output) can be designated as an autostart queue. Because all of a queue manager's autostart queues on a node can be started with a single command, autostart queues eliminate the need for lengthy queue startup procedures.

In an OpenVMS Cluster, autostart queues can be set up to run on one of several nodes. If a queue is set up this way, and the node on which the queue is running leaves the cluster, the queue can fail over to another node and remain available to the cluster.

The /AUTOSTART_ON qualifier designates an execution queue as an autostart queue.

Qualifiers

/AUTOSTART_ON=(node::[device][,...])

Designates the queue as an autostart execution queue and specifies the node, or node and device, on which the queue can be located. For batch queues, only node is applicable.

In a cluster, you can specify more than one node (or node and device) on which a queue can run, in the preferred order in which nodes should claim the queue. This allows the queue to fail over to another node if the node on which the queue is running leaves the cluster.

When you enter the INITIALIZE/QUEUE command with the /AUTOSTART_ON qualifier, you must initially activate the queue for autostart, either by specifying the /START qualifier with the INITIALIZE/QUEUE command or by entering a START/QUEUE command. However, the queue will not begin processing jobs until the ENABLE AUTOSTART/QUEUES command is entered for a node on which the queue can run.

This qualifier cannot be used in conjunction with the /ON or /GENERIC qualifier. However, if you are reinitializing an existing queue, you can specify the /AUTOSTART_ON qualifier for a queue previously created or started with the /ON qualifier. Doing so overrides the /ON qualifier and makes the queue an autostart queue.

For more information about autostart queues, see the chapter about queues in HP OpenVMS System Manager's Manual, Volume 1: Essentials.

/BASE_PRIORITY=n

Specifies the base process priority at which jobs are initiated from a batch execution queue. By default, if you omit the qualifier, jobs are initiated at the same priority as the base priority established by DEFPRI at system generation (usually 4). The base priority specifier can be any decimal value from 0 to 15.

You also can specify this qualifier for an output execution queue. In this context the /BASE_PRIORITY qualifier establishes the base priority of the symbiont process when the symbiont process is created.

/BATCH

/NOBATCH (default)

Specifies that you are initializing a batch queue. If you are reinitializing an existing queue, you can use the /BATCH qualifier only if the queue was created as a batch queue.

A batch queue is classified as either an execution queue or a generic queue. By default, the /BATCH qualifier initializes an execution queue. To specify a generic batch queue, use the /GENERIC qualifier together with the /BATCH qualifier.

The /BATCH and /DEVICE qualifiers are mutually exclusive; the /NOBATCH and /NODEVICE qualifiers cannot be used together.

/BLOCK_LIMIT=([lowlim,]uplim)

/NOBLOCK_LIMIT (default)

Limits the size of print jobs that can be processed on an output execution queue. The /BLOCK_LIMIT qualifier allows you to reserve certain printers for certain size jobs. You must specify at least one of the parameters.

The lowlim parameter is a decimal number referring to the minimum number of blocks accepted by the queue for a print job. If a print job is submitted that contains fewer blocks than the lowlim value, the job remains pending until the block limit for the queue is changed. After the block limit for the queue is decreased sufficiently, the job is processed.

The uplim parameter is a decimal number referring to the maximum number of blocks that the queue accepts for a print job. If a print job is submitted that exceeds this value, the job remains pending until the block limit for the queue is changed. After the block limit for the queue is increased sufficiently, the job is processed.

If you specify only an upper limit for jobs, you can omit the parentheses. For example, /BLOCK_LIMIT=1000 means that only jobs with 1000 blocks or less are processed in the queue. To specify only a lower job limit, you must use a null string ("") to indicate the upper specifier. For example, /BLOCK_LIMIT=(500,"") means any job with 500 or more blocks is processed in the queue. You can specify both a lower and upper limit. For example, /BLOCK_LIMIT=(200,2000) means that jobs with less than 200 blocks or more than 2000 blocks are not processed in the queue.

The /NOBLOCK_LIMIT qualifier cancels the previous setting established by the /BLOCK_LIMIT qualifier for that queue.

/CHARACTERISTICS=(characteristic[,...])

/NOCHARACTERISTICS (default)

Specifies one or more characteristics for processing jobs on an execution queue. If you specify only one characteristic, you can omit the parentheses. If a queue does not have all the characteristics that have been specified for a job, the job remains pending. Each time you specify the /CHARACTERISTICS qualifier, all previously set characteristics are cancelled. Only the characteristics specified with the qualifier are established for the queue.

Queue characteristics are installation specific. The characteristic parameter can be either a value from 0 to 127 or a characteristic name that has been defined by the DEFINE/CHARACTERISTIC command.

The /NOCHARACTERISTICS qualifier cancels any settings previously established by the /CHARACTERISTICS qualifier for that queue.

/CLOSE

Prevents jobs from being entered in the queue through PRINT or SUBMIT commands or as a result of requeue operations. To allow jobs to be entered, use the /OPEN qualifier. Whether a queue accepts or rejects new job entries is independent of the queue's state (such as paused, stopped, or stalled). When a queue is marked closed, jobs executing continue to execute. Jobs pending in the queue continue to be candidates for execution.

/CPUDEFAULT=time

Defines the default CPU time limit for all jobs in this batch execution queue. You can specify time as delta time, 0, INFINITE, or NONE (default). You can specify up to 497 days of delta time.

If the queue does not have a specified CPUMAXIMUM time limit and the value established in the user authorization file (UAF) has a specified CPU time limit of NONE, either the value 0 or the keyword INFINITE allows unlimited CPU time. If you specify NONE, the CPU time value defaults to the value specified either in the UAF or by the SUBMIT command (if included). CPU time values must be greater than or equal to the number specified by the system parameter PQL_MCPULM. The time cannot exceed the CPU time limit set by the /CPUMAXIMUM qualifier. For information on specifying delta time, see the OpenVMS User's Manual or the online help topic Date. For more information on specifying CPU time limits, see Table DCLI-1.

/CPUMAXIMUM=time

Defines the maximum CPU time limit for all jobs in a batch execution queue. You can specify time as delta time, 0, INFINITE, or NONE (default). You can specify up to 497 days of delta time.

The /CPUMAXIMUM qualifier overrides the time limit specified in the user authorization file (UAF) for any user submitting a job to the queue. Either the value 0 or the keyword INFINITE allows unlimited CPU time. If you specify NONE, the CPU time value defaults to the value specified either in the UAF or by the SUBMIT command (if included). CPU time values must be greater than or equal to the number specified by the system parameter PQL_MCPULM.

For information on specifying delta times, see the OpenVMS User's Manual or the online help topic Date. For more information on specifying CPU time limits, see Table DCLI-1.

A CPU time limit for processes is specified by each user record in the system UAF. You also can specify the following: a default CPU time limit or a maximum CPU time limit for all jobs in a given queue, or a default CPU time limit for individual jobs in the queue. Table DCLI-1 shows the action taken for each value specified and possible combinations of specifications.

Table DCLI-1 CPU Time Limit Specifications and Actions
CPU Time Limit Specified by the SUBMIT Command? Default CPU Time Limit Specified for the Queue? Maximum CPU Time Limit Specified for the Queue? Action Taken
No No No Use the UAF value.
Yes No No Use the smaller of SUBMIT command and UAF values.
Yes Yes No Use the smaller of SUBMIT command and UAF values.
Yes No Yes Use the smaller of SUBMIT command and queue's maximum values.
Yes Yes Yes Use the smaller of SUBMIT command and queue's maximum values.
No Yes Yes Use the smaller of queue's default and maximum values.
No No Yes Use the maximum value.
No Yes No Use the smaller of UAF and queue's default values.

/DEFAULT=(option[,...])

/NODEFAULT

Establishes defaults for certain options of the PRINT command. Defaults are specified by the list of options. If you specify only one option, you can omit the parentheses. After you set an option for the queue with the /DEFAULT qualifier, you do not have to specify that option in your PRINT command. If you do specify these options in your PRINT command, the values specified with the PRINT command override the values established for the queue with the /DEFAULT qualifier.

You cannot use the /DEFAULT qualifier with the /GENERIC qualifier.

Possible options are as follows:
[NO]BURST[=keyword] Controls whether two file flag pages with a burst bar between them are printed preceding output. If you specify the value ALL (default), these flag pages are printed before each file in the job. If you specify the value ONE, these flag pages are printed once before the first file in the job.
[NO]FEED Controls whether a form feed is inserted automatically at the end of a page.
[NO]FLAG[=keyword] Controls whether a file flag page is printed preceding output. If you specify the value ALL (default), a file flag page is printed before each file in the job. If you specify the value ONE, a file flag page is printed once before the first file in the job.
FORM=type Specifies the default form for an output execution queue. If a job is submitted without an explicit form definition, this form is used to process the job. If no form type is explicitly specified with the FORM keyword, the system assigns the form DEFAULT to the queue. See also the description of the /FORM_MOUNTED=type qualifier.
[NO]TRAILER[=keyword] Controls whether a file trailer page is printed following output. If you specify the value ALL (default), a file trailer page is printed after each file in the job. If you specify the value ONE, a trailer page is printed once after the last file in the job.

When you specify the BURST option for a file, the [NO]FLAG option does not add or subtract a flag page from the two flag pages that are printed preceding the file.

For information on establishing mandatory queue options, see the description of the /SEPARATE qualifier. For more information on specifying default queue options, see the chapter on queues in the HP OpenVMS System Manager's Manual.

/DESCRIPTION=string

/NODESCRIPTION (default)

Specifies a string of up to 255 characters used to provide operator-supplied information about the queue.

Enclose strings containing lowercase letters, blanks, or other nonalphanumeric characters (including spaces) in quotation marks (" ").

The /NODESCRIPTION qualifier removes any descriptive text that may be associated with the queue.

/DEVICE[=option]

/NODEVICE

Specifies that you are initializing an output queue of a particular type. If you are reinitializing an existing queue, you can use the /DEVICE qualifier only if the queue was created as an output queue. Possible options are as follows:
PRINTER Indicates a printer queue.
SERVER Indicates a server queue. A server queue is controlled by the user-modified or user-written symbiont specified with the /PROCESSOR qualifier.
TERMINAL Indicates a terminal queue.

If you specify the /DEVICE qualifier without a queue type, the /DEVICE=PRINTER qualifier is used by default.

An output queue is classified as either an execution or generic queue. By default, the /DEVICE qualifier initializes an execution queue of the designated type. To specify a generic printer, server, or terminal queue, use the /GENERIC qualifier with the /DEVICE qualifier.

You specify the queue type with the /DEVICE qualifier for informational purposes. When an output execution queue is started, the symbiont associated with the queue determines the actual queue type. The standard symbiont examines device characteristics to establish whether the queue should be marked as printer or terminal. By convention, user-modified and user-written symbionts mark the queue as a server queue. The device type of a generic queue need not match the device type of its execution queues.

The /DEVICE and /BATCH qualifiers are mutually exclusive; the /NODEVICE and /NOBATCH qualifiers cannot be used together.

/DISABLE_SWAPPING

/NODISABLE_SWAPPING (default)

Controls whether batch jobs executed from a queue can be swapped in and out of memory.

/ENABLE_GENERIC (default)

/NOENABLE_GENERIC

Specifies whether files queued to a generic queue that does not specify explicit queue names with the /GENERIC qualifier can be placed in this execution queue for processing. For more information, see the description of the /GENERIC qualifier.

/FORM_MOUNTED=type

Specifies the mounted form for an output execution queue.

If no form type is explicitly specified, the system assigns the form DEFAULT to the queue.

If the stock of the mounted form does not match the stock of the default form, as indicated by the /DEFAULT=FORM qualifier, all jobs submitted to this queue without an explicit form definition enter a pending state and remains pending until the stock of the mounted form of the queue is identical to the stock of the form associated with the job.

If a job is submitted with an explicit form and the stock of the explicit form is not identical to the stock of the mounted form, the job enters a pending state and remains pending until the stock of the mounted form of the queue is identical to the stock of the form associated with the job.

To specify the form type, use either a numeric value or a form name that has been defined by the DEFINE/FORM command. Form types are installation-specific. You cannot use the /FORM_MOUNTED qualifier with the /GENERIC qualifier.

/GENERIC[=(queue-name[,...])]

/NOGENERIC (default)

Specifies a generic queue. Also specifies that jobs placed in this queue can be moved for processing to compatible execution queues. The /GENERIC qualifier optionally accepts a list of target execution queues that have been previously defined. For a generic batch queue, these target queues must be batch execution queues. For a generic output queue, these target queues must be output execution queues, but can be of any type (printer, server, or terminal). For example, a generic printer queue can feed a mixture of printer and terminal execution queues.

If you do not specify any target execution queues with the /GENERIC qualifier, jobs can be moved to any execution queue that (1) is initialized with the /ENABLE_GENERIC qualifier, and (2) is the same type (batch or output) as the generic queue.

To define the queue as a generic batch or output queue, you use the /GENERIC qualifier with either the /BATCH or the /DEVICE qualifier. If you specify neither /BATCH nor /DEVICE on creation of a generic queue, the queue becomes a generic printer queue by default.

You cannot use the /SEPARATE qualifier with the /GENERIC qualifier.

/JOB_LIMIT=n

Indicates the number of batch jobs that can be executed concurrently from the queue. Specify a number in the range 1 to 65535. The job limit default value for n is 1.

/LIBRARY=filename

/NOLIBRARY

Specifies the file name for the device control library. When you initialize an output execution queue, you can use the /LIBRARY qualifier to specify an alternate device control library. The default library is SYS$LIBRARY:SYSDEVCTL.TLB. You can use only a file name as the parameter of the /LIBRARY qualifier. The system always assumes that the file is located in SYS$LIBRARY and that the file type is .TLB.

/NAME_OF_MANAGER=name

Identifies the name of the queue manager to control the queue. Once the queue is created, the queue manager assignment may not be altered.

If the /NAME_OF_MANAGER qualifier is omitted, then the default name SYS$QUEUE_MANAGER is used.

If the INITIALIZE/QUEUE command is used to modify a queue, and that queue is not controlled by the default queue manager, then the name of the controlling queue manager should be specified with the /NAME_OF_MANAGER qualifier. Alternately, the logical name SYS$QUEUE_MANAGER can be defined to be the correct queue manager, making that queue manager the default for the current process.

/NO_INITIAL_FF

/NONO_INITIAL_FF (default)

Allows user to specify whether a form feed should be sent to a printer device when a queue starts. To suppress the initial form feed, use the /NO_INITIAL_FF qualifier.

The /NONO_INITIAL_FF qualifier sends a form feed to the output device to ensure the paper is at the top of a page before printing begins.

/ON=[node::]device[:] (printer, terminal, server queue)

/ON=node:: (batch queue)

Specifies the node or device, or both, on which this execution queue is located. For batch execution queues, you can specify only the node name. For output execution queues, you can include both the node name and the device name. By default, a queue executes on the same node from which you start the queue. The default device parameter is the same as the queue name.

You can specify an IP address and port number, in quotation marks, for the device. For more information about specifying IP addresses, see the TCP/IP Services for OpenVMS documentation.

The node name is used in OpenVMS Cluster systems; it must match the node name specified by the system parameter SCSNODE for the OpenVMS computer on which the queue executes.

You cannot use the /ON qualifier with the /AUTOSTART_ON or /GENERIC qualifier; however, if you are reinitializing an existing queue, you can specify the /ON qualifier for a queue previously created or started with the /AUTOSTART_ON qualifier. Doing so overrides the /AUTOSTART_ON option and makes the queue a nonautostart queue.

/OPEN (default)

Allows jobs to be entered in the queue through PRINT or SUBMIT commands or as the result of requeue operations. To prevent jobs from being entered in the queue, use the /CLOSE qualifier. Whether a queue accepts or rejects new job entries is independent of the queue's state (such as paused, stopped, or stalled).

/OWNER_UIC=uic

Enables you to change the user identification code (UIC) of the queue. Specify the UIC by using standard UIC format as described in the HP OpenVMS Guide to System Security. The default UIC is [1,4].

/PROCESSOR=filename

/NOPROCESSOR

Allows you to specify your own print symbiont for an output execution queue. You can use any valid file name as a parameter of the /PROCESSOR qualifier. The system supplies the device and directory name SYS$SYSTEM and the file type .EXE. If you use this qualifier for an output queue, it specifies that the symbiont image to be executed is SYS$SYSTEM:filename.EXE.

By default, SYS$SYSTEM:PRTSMB.EXE is the symbiont image associated with an output execution queue.

The /NOPROCESSOR qualifier cancels any previous setting established with the /PROCESSOR qualifier and causes SYS$SYSTEM:PRTSMB.EXE to be used.

/PROTECTION=(ownership[:access],...)

Specifies the protection of the queue:

A null access specification means no access. The default protection is (SYSTEM:M, OWNER:D, GROUP:R, WORLD:S). If you include only one protection code, you can omit the parentheses. For more information on specifying protection codes, see the HP OpenVMS Guide to System Security. For more information on controlling queue operations through UIC-based protection, see the chapter on queues in the HP OpenVMS System Manager's Manual.

/RAD=n (Alpha/I64 only)

Specifies the RAD number on which to run batch jobs assigned to the queue. The RAD value is validated as a positive integer between 0 and the value returned by the $GETSYI item code, SYI$_RAD_MAX_RADS.

Supported only on AlphaServer GS series systems.

/RECORD_BLOCKING (default)

/NORECORD_BLOCKING

Determines whether the symbiont can concatenate (or block together) output records for transmission to the output device. If you specify the /NORECORD_BLOCKING qualifier, the symbiont sends each formatted record in a separate I/O request to the output device. For the standard OpenVMS print symbiont, record blocking can have a significant performance advantage over single-record mode.

/RETAIN[=option]

/NORETAIN (default)

Holds jobs in the queue in a retained state after they have executed. The /NORETAIN qualifier enables you to reset the queue to the default. Possible options are as follows:
ALL (default) Holds all jobs in the queue after execution.
ERROR Holds in the queue only jobs that complete unsuccessfully.

A user can request a job retention option for a job by specifying the /RETAIN qualifier with the PRINT, SUBMIT, or SET ENTRY command; however, the job retention option you specify for a queue overrides any job retention option requested by a user for a job in that queue.

/SCHEDULE=SIZE (default)

/SCHEDULE=NOSIZE

Specifies whether pending jobs in an output execution queue are scheduled for printing based on the size of the job. When the default qualifier /SCHEDULE=SIZE is in effect, shorter jobs print before longer ones.

When the /SCHEDULE=NOSIZE qualifier is in effect, jobs are not scheduled according to size.

If you enter this command while there are pending jobs in any queue, its effect on future jobs is unpredictable.

/SEPARATE=(option[,...])

/NOSEPARATE (default)

Specifies the mandatory queue options, or job separation options, for an output execution queue. Job separation options cannot be overridden by the PRINT command.

You cannot use the /SEPARATE qualifier with the /GENERIC qualifier.

The job separation options are as follows:
[NO]BURST Specifies whether two job flag pages with a burst bar between them are printed at the beginning of each job.
[NO]FLAG Specifies whether a job flag page is printed at the beginning of each job.
[NO]TRAILER Specifies whether a job trailer page is printed at the end of each job.
[NO]RESET=(module[,...]) Specifies one or more device control library modules that contain the job reset sequence for the queue. The specified modules from the queue's device control library (by default SYS$LIBRARY:SYSDEVCTL) are used to reset the device at the end of each job. The RESET sequence occurs after any file trailer and before any job trailer. Thus, all job separation pages are printed when the device is in its RESET state.

When you specify the /SEPARATE=BURST qualifier, the [NO]FLAG separation option does not add or subtract a flag page from the two flag pages that are printed preceding the job.

For information on establishing queue options that can be overridden, see the description of the /DEFAULT qualifier.

For more information on specifying mandatory queue options, see the chapter on queues in the HP OpenVMS System Manager's Manual.

/START

/NOSTART (default)

Starts the queue being initialized by the current INITIALIZE/QUEUE command.

For autostart queues, this qualifier activates the queue for autostart. The queue begins processing jobs when autostart is enabled with the ENABLE AUTOSTART/QUEUES command on any node on which the queue can run.

/WSDEFAULT=n

Defines for a batch job a working set default, the default number of physical pages that the job can use.

The value set by this qualifier overrides the value defined in the user authorization file (UAF) of any user submitting a job to the queue.

Specify the value of n as a number of 512-byte pagelets on Alpha systems or 512-byte pages on VAX. Note that OpenVMS rounds this value up to the nearest CPU-specific page so that the actual amount of physical memory allowed may be larger than the specified amount on Alpha. For further information, see the HP OpenVMS System Manager's Manual.

If you specify 0 or NONE, the working set default value defaults to the value specified in the UAF or by the SUBMIT command (if it includes a WSDEFAULT value).

You also can specify this qualifier for an output execution queue. Used in this context, the /WSDEFAULT qualifier establishes the working set default of the symbiont process for an output execution queue when the symbiont process is created.

For more information about the way a working set default affects batch jobs, see Table DCLI-2.

/WSEXTENT=n

Defines for the batch job a working set extent, the maximum amount of physical memory that the job can use. The job only uses the maximum amount of physical memory when the system has excess free pages. The value set by this qualifier overrides the value defined in the user authorization file (UAF) of any user submitting a job to the queue.

Specify the value of n as a number of 512-byte pagelets on Alpha or and 512-byte pages on VAX. Note that OpenVMS rounds this value up to the nearest CPU-specific page so that the actual amount of physical memory allowed may be larger than the specified amount on Alpha.

If you specify 0 or NONE, the working set extent value defaults to the value specified in the UAF or by the SUBMIT command (if it includes a WSEXTENT value).

You also can specify this qualifier for an output execution queue. Used in this context, the /WSEXTENT qualifier establishes the working set extent of the symbiont process for an output execution queue when the symbiont process is created.

For more information about the way a working set extent affects batch jobs, see Table DCLI-2.

/WSQUOTA=n

Defines for a batch job a working set quota, the amount of physical memory that is guaranteed to the job.

The value set by this qualifier overrides the value defined in the user authorization file (UAF) of any user submitting a job to the queue.

Specify the value of n as a number of 512-byte pagelets on OpenVMS Alpha or 512-byte pages on OpenVMS VAX. OpenVMS rounds this value up to the nearest CPU-specific page so that the actual amount of physical memory allowed may be larger than the specified amount on OpenVMS Alpha. For further information, see the HP OpenVMS System Manager's Manual.

If you specify 0 or NONE, the working set quota value defaults to the value specified in the UAF or by the SUBMIT command (if it includes a WSQUOTA value).

You also can specify this qualifier for an output execution queue. Used in this context, the /WSQUOTA qualifier establishes the working set quota of the symbiont process for an output execution queue when the symbiont process is created.

Working set default, working set quota, and working set extent values are included in each user record in the system UAF. You can specify working set values for individual jobs or for all jobs in a given queue. The decision table (Table DCLI-2) shows the action taken for different combinations of specifications that involve working set values.

Table DCLI-2 Working Set Default, Extent, and Quota Decision
Is the SUBMIT command value specified? Is the queue value specified? Action taken
No No Use the UAF value.
No Yes Use value for the queue.
Yes Yes Use smaller of the two values.
Yes No Compare specified value with UAF value; use the smaller.

Examples

#1 

$ INITIALIZE/QUEUE/PROCESSOR=TELNETSYM -
_$ /ON="192.168.1.101:9100" SYS$PRINT

This example initializes the SYS$PRINT print queue, specifying the TELNETSYM print symbiont, for the printer with the IP address 192.168.1.101 at TCP port 9100. For more information about TELNETSYM, see the TCP/IP Services for OpenVMS Management Guide.

#2 

$ INITIALIZE/QUEUE/BATCH/START -
_$ /AUTOSTART_ON=(DATA::, WARF::, DEANNA::) BATCH_1

The INITIALIZE/QUEUE command in this example creates the batch queue BATCH_1, and designates it as an autostart queue capable of executing on node DATA, WARF, or DEANNA. The /START qualifier activates the queue for autostart. The queue will begin executing on the first node (in the list of nodes specified) for which the ENABLE AUTOSTART/QUEUES command is entered.

If the node on which BATCH_1 is executing is taken out of the OpenVMS Cluster, the queue will be stopped on that node and will fail over to the first available node in the node list on which autostart is enabled for a queue manager SYS$QUEUE_MANAGER.

As long as autostart is enabled on one of the nodes in the list, this queue will be started and available to execute batch jobs. If all three nodes in the example are shut down or if autostart is disabled, the queue will remain stopped until one of the three nodes in the node list joins the cluster and executes the ENABLE AUTOSTART/QUEUES command.

The ENABLE AUTOSTART/QUEUES and INITIALIZE/QUEUE commands affect only the queues managed by the default queue manager SYS$QUEUE_MANAGER because the /NAME_OF_MANAGER qualifier is not specified.

$ INITIALIZE/QUEUE/START/BATCH/JOB_LIMIT=3 SYS$BATCH
$ INITIALIZE/QUEUE/START/BATCH/JOB_LIMIT=1/WSEXTENT=2000 BIG_BATCH

In this example, the first INITIALIZE/QUEUE command creates a batch queue called SYS$BATCH that can be used for any batch job. The /JOB_LIMIT qualifier allows three jobs to execute concurrently. The second INITIALIZE/QUEUE command creates a second batch queue called BIG_BATCH that is designed for large jobs. Only one job can execute at a time. The working set extent can be as high as 125 pages on OpenVMS Alpha (on a system with 8KB pages) or 2000 pages on OpenVMS VAX.

$ INITIALIZE/QUEUE/START/GENERIC=(LPA0_PRINT,LPB0_PRINT) SYS$PRINT
$ INITIALIZE/QUEUE/START/FORM_MOUNTED=LETTER-
_$ /BLOCK_LIMIT=50/ON=TXA5: LQP

In this example, the first three INITIALIZE/QUEUE commands set up printer queues. Both queue LPA0_PRINT and LPB0_PRINT are set up to put a flag page before each file within a job and a trailer page after only the last page in a job. In addition, LPB0_PRINT has a minimum block size of 1000; therefore, only print jobs larger than 1000 blocks can execute on that queue. SYS$PRINT is established as a generic queue that can direct jobs to either LPA0_PRINT or LPB0_PRINT. Jobs that are too small to run on LPB0_PRINT will be queued from SYS$PRINT to LPA0_PRINT.

The last INITIALIZE/QUEUE command sets up a terminal queue on TXA5. A job queued with a form that has a stock type other than the stock type of form LETTER remains pending in the queue until a form with the same stock type is mounted on the queue, or until the entry is deleted from the queue or moved to another queue. LETTER has been established at this site to indicate special letterhead paper. The block size limit is 50, indicating that this queue is reserved for jobs smaller than 51 blocks.

$ INITIALIZE/QUEUE/ON=QUEBID::/BATCH/RAD=0   BATCHQ1
 
$ SHOW QUEUE/FULL BATCHQ1
Batch queue BATCHQ1, stopped, QUEBID::
 /BASE_PRIORITY=4 /JOB_LIMIT=1 /OWNER=[SYSTEM]
 /PROTECTION=(S:M,O:D,G:R,W:S) /RAD=0

This example creates or reinitializes the batch queue BATCHQ1 to run on node QUEBID. All jobs assigned to this queue will run on RAD 0.
