VMS Help INITIALIZE, /QUEUE *Conan The Librarian (sorry for the slow response - running on an old VAX) |
|
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[:]
| 1 - 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.
| 2 - Qualifiers |
2.1 - /AUTOSTART_ON
/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, refer to the chapter
about queues in OpenVMS System Manager's Manual, Volume 1:
Essentials.
2.2 - /BASE_PRIORITY
/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.
2.3 - /BATCH
/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.
2.4 - /BLOCK_LIMIT
/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.
2.5 - /CHARACTERISTICS
/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.
2.6 - /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.
2.7 - /CPUDEFAULT
/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, refer to the OpenVMS User's Manual or the online help
topic DCL_Tips (subtopic Date_Time).
2.8 - /CPUMAXIMUM
/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, refer to the OpenVMS
User's Manual or the online help topic DCL_Tips (subtopic Date_
Time).
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. The following table shows the action taken for each
value specified and possible combinations of specifications.

and queue's default
values.
2.9 - /DEFAULT
/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, refer to the chapter on queues
in the OpenVMS System Manager's Manual.
2.10 - /DESCRIPTION
/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.
2.11 - /DEVICE
/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.
2.12 - /DISABLE_SWAPPING
/DISABLE_SWAPPING
/NODISABLE_SWAPPING (default)
Controls whether batch jobs executed from a queue can be swapped
in and out of memory.
2.13 - /ENABLE_GENERIC
/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.
2.14 - /FORM_MOUNTED
/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.
2.15 - /GENERIC
/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.
2.16 - /JOB_LIMIT
/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 255. The job limit default value for n is 1.
2.17 - /LIBRARY
/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.
2.18 - /NAME_OF_MANAGER
/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.
2.19 - /NO_INITIAL_FF
/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.
2.20 - /ON
/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.
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.
2.21 - /OPEN
/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).
2.22 - /OWNER_UIC
/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 OpenVMS Guide to System Security. The default UIC is
[1,4].
2.23 - /PROCESSOR
/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.
2.24 - /PROTECTION
/PROTECTION=(ownership[:access],...)
Specifies the protection of the queue:
o Specify the ownership parameter as system (S), owner (O),
group (G), or world (W).
o Specify the access parameter as read (R), submit (S), manage
(M), or delete (D).
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, refer to
the OpenVMS Guide to System Security. For more information on
controlling queue operations through UIC-based protection, refer
to the chapter on queues in the OpenVMS System Manager's Manual.
2.25 - /RECORD_BLOCKING
/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.
2.26 - /RETAIN
/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 Holds all jobs in the queue after execution.
(default)
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.
2.27 - /SCHEDULE
/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.
2.28 - /SEPARATE
/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, refer
to the chapter on queues in the OpenVMS System Manager's Manual.
2.29 - /START
/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.
2.30 - /WSDEFAULT
/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, refer to the
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.
2.31 - /WSEXTENT
/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.
2.32 - /WSQUOTA
/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, refer
to the 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 shows the action taken
for different combinations of specifications that involve working
set values.
Is the SUBMIT Is the
command value queue value
specified? 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.
| 3 - Examples |
1.$ 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.
2.$ 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$BATCH that can be used for any batch
job. The /JOB_LIMIT qualifier allows three jobs to execute
concurrently. The second INITIALIZE/QUEUE command creates
a second batch queue called BIG_BATCH that is designed for
large jobs. Only one job can execute at a time. The working
set extent can be as high as 125 pages on OpenVMS Alpha (on a
system with 8KB pages) or 2000 pages on OpenVMS VAX.
3.$ INITIALIZE/QUEUE/START/DEFAULT=(FLAG,TRAILER=ONE)-
_$ /ON=LPA0: LPA0_PRINT
$ INITIALIZE/QUEUE/START/DEFAULT=(FLAG,TRAILER=ONE)-
_$ /BLOCK_LIMIT=(1000,"")/ON=LPB0: LPB0_PRINT
$ 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
