VMS Help START, /QUEUE *Conan The Librarian (sorry for the slow response - running on an old VAX) |
|
Starts or restarts the specified queue after it has been
initialized. You also can use this command to change the options
of the specified queue. The /QUEUE qualifier is required.
Requires manage (M) access to the queue.
Format
START/QUEUE queue-name[:]
| 1 - Parameter |
queue-name[:]
Specifies the name of the queue to be started or restarted.
| 2 - Qualifiers |
2.1 - /ALIGN
/ALIGN[=(option[,...])]
Prints alignment pages to aid in aligning printer forms. Use this
qualifier only when restarting an output execution queue from a
paused state.
After the alignment is complete, the queue enters a paused state
until you restart it by reentering the START/QUEUE command.
Printing resumes from the point where alignment data started;
that is, the task is backspaced over the pages printed for
alignment.
Possible options are as follows:
MASK Specifies that input data is masked by replacing
alphabetic characters with x's and numbers with 9s;
nonalphanumeric characters are not masked. Mask
characters allow you to prevent the printing of sensitive
information. If you omit the MASK option, data is printed
unaltered.
n Specifies the number of alignment pages to print. The
value of n can be from 1 to 20. By default, one page of
alignment data is printed.
2.2 - /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. Both node and device must be specified for output
queues. For batch queues, only node is applicable.
In an OpenVMS 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.
For autostart queues, the START/QUEUE command activates the queue
for autostart. The queue will begin processing jobs when the
ENABLE AUTOSTART/QUEUES command is entered for a node on which
the queue can run.
This qualifier cannot be used with the /ON or /GENERIC qualifier;
however, you can specify the /AUTOSTART_ON qualifier for a queue
previously created or started with the /ON qualifier. Doing so
overrides the /ON option and makes the queue an autostart queue.
For more information about autostart queues, refer to the chapter
about managing queues in the OpenVMS System Manager's Manual.
2.3 - /BACKWARD
/BACKWARD=n
Restarts a print queue n pages before the current page; n
defaults to 1. If you omit the page value, printing resumes
at the top of the current page. Use this qualifier only when
restarting an output execution queue from a paused state.
NOTE
Using the START/QUEUE/BACKWARD=n command to restart a print
job that uses Fortran carriage control and that was printed
with the /NOFEED qualifier can have unexpected results, in
particular:
o The page positioning in the restarted job may not be
correct: the output may not begin at the top of the page
specified by n.
o The output from the print job may be preceded by extra
meaningless information.
2.4 - /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.
2.5 - /BLOCK_LIMIT
/BLOCK_LIMIT=([lowlim,]uplim)
/NOBLOCK_LIMIT
Limits the size of print jobs that can be processed on an output
execution queue. This 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 that are accepted by the queue for a print job.
If a print job is submitted that contains fewer blocks than the
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 are accepted by the queue 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 the queue.
2.6 - /CHARACTERISTICS
/CHARACTERISTICS=(characteristic[,...])
/NOCHARACTERISTICS
Specifies one or more characteristics for processing jobs
on an execution queue. If a queue does not have all the
characteristics that have been specified for a job, the job
remains pending. If you specify only one characteristic, you can
omit the parentheses. Each time you specify the /CHARACTERISTICS
qualifier, all previously set characteristics are canceled. 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 the queue.
2.7 - /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 already
pending in the queue continue to be candidates for execution.
2.8 - /CPUDEFAULT
/CPUDEFAULT=time
Defines the default CPU time limit for jobs in this batch
execution queue. You can specify time as delta time, 0, INFINITE,
or NONE. 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.
For information on specifying delta times, refer to the OpenVMS
User's Manual or the online help topic DCL_Tips (subtopic Date_
Time).
2.9 - /CPUMAXIMUM
/CPUMAXIMUM=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. 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 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).
2.10 - /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 commands. 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 Specifies 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 flag page is
printed before each file in the job. If
you specify the value ONE, a 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
qualifier.
[NO]TRAILER[=keyword] Controls whether a file trailer page is
printed following output. If you specify
the value ALL (default), a 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 OpenVMS System Manager's Manual.
2.11 - /DESCRIPTION
/DESCRIPTION=string
/NODESCRIPTION
Specifies a string of up to 255 characters that is 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.
2.12 - /DISABLE_SWAPPING
/DISABLE_SWAPPING
/NODISABLE_SWAPPING
Controls whether batch jobs executed from a queue can be swapped
in and out of memory.
2.13 - /ENABLE_GENERIC
/ENABLE_GENERIC
/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 remain 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 - /FORWARD
/FORWARD=n
Advances the specified number of pages before resuming printing
the current file in the current job; the default is 1. If you
omit the page value, printing resumes at the top of the next
page. Use this qualifier only when restarting an output execution
queue from a paused state.
2.16 - /GENERIC
/GENERIC[=(queue-name[,...])]
/NOGENERIC
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.
Use the /GENERIC qualifier to change the list of target nodes
for a generic queue. The queue must have been initialized as a
generic queue with the INITIALIZE/QUEUE/GENERIC command.
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 the /BATCH nor the /DEVICE
qualifier on creation of a generic queue, by default the queue
becomes a generic printer queue.
2.17 - /JOB_LIMIT
/JOB_LIMIT=n
Specifies the number of batch jobs that can be executed
concurrently from the queue. Specify a number in the range 0
to 255.
2.18 - /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. 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.
2.19 - /NEXT
Aborts the currently suspended print job and begins processing of
the first pending job in the queue. Use this qualifier only when
restarting an output execution queue from a paused state.
2.20 - /NO_INITIAL_FF
/NO_INITIAL_FF
/NONO_INITIAL_FF (default)
Specifies 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 that the paper is at the top of a page before
printing begins.
2.21 - /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.
The node name is used only in VAXcluster systems; it must match
the node name specified by the system parameter SCSNODE for the
VAX computer on which the queue executes.
You cannot use the /ON qualifier with the /AUTOSTART_ON or
/GENERIC qualifier; however, you can specify the /ON qualifier
for a queue previously created or started with the /AUTOSTART_ON
qualifier. Doing so overrides the /AUTOSTART_ON qualifier and
makes the queue a nonautostart queue.
2.22 - /OPEN
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).
2.23 - /OWNER_UIC
/OWNER_UIC=uic
Requires manage (M) access to the queue.
Enables you to change the user identification code (UIC) of the
queue. Specify the UIC by using standard format as described in
the OpenVMS User's Manual.
2.24 - /PROCESSOR
/PROCESSOR=filename
/NOPROCESSOR
Requires OPER (operator) privilege to change the file name from
the one with which the queue was initialized.
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 by the /PROCESSOR qualifier, and causes
SYS$SYSTEM:PRTSMB.EXE to be used.
2.25 - /PROTECTION
/PROTECTION=(ownership[:access],...)
Requires OPER (operator) privilege, or control (C) and execute
(E) access to the queue.
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.
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 OpenVMS System Manager's Manual.
2.26 - /RECORD_BLOCKING
/RECORD_BLOCKING
/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.
2.27 - /RETAIN
/RETAIN[=option]
/NORETAIN
Holds jobs in the queue in a retained status 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.
ERROR Holds in the queue only jobs that fail to complete.
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.
2.28 - /SCHEDULE
/SCHEDULE=[NO]SIZE
Specifies whether pending jobs in an output queue are
scheduled for printing based on the size of the job. When the
/SCHEDULE=SIZE qualifier is in effect, shorter jobs are printed
before longer ones. When the /SCHEDULE=NOSIZE qualifier is
in effect, jobs are printed in the order they were submitted,
regardless of size.
If you enter this command while there are pending jobs in any
queue, its effect on future jobs is unpredictable.
2.29 - /SEARCH
/SEARCH="search-string"
Specifies that printing is to resume at the page containing
the specified string. The search for the string moves forward,
beginning on the page following the current page. During the
search, consecutive tabs and spaces are treated as a single
space, and character case is ignored. The string can be from 1
to 63 characters and must be enclosed in quotation marks (" ").
Use this qualifier only when restarting an output execution queue
from a paused state.
2.30 - /SEPARATE
/SEPARATE=(option[,...])
/NOSEPARATE
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 each time a job reset occurs.
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 /SEPARATE=BURST, 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 OpenVMS System Manager's Manual.
2.31 - /TOP_OF_FILE
Resumes printing at the beginning of the file that was current
when the output execution queue paused. Use this qualifier only
when restarting an output execution queue from a paused state.
2.32 - /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.
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 execution
queue when the symbiont process is created.
Specify the value of n as a number of 512-byte pagelets on Alpha
or 512-byte pages on VAX. Note that the operating systems rounds
up this value 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 the value 0 or NONE, the working set default
value defaults to the value specified in the UAF or by the SUBMIT
command (if included).
2.33 - /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 uses
the maximum amount of physical memory only 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.
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.
Specify the value of n as a number of 512-byte pagelets on
Alpha or 512-byte pages on VAX. Note that the operating system
rounds up this value 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 the value 0 or NONE, the working set extent value
defaults to the value specified in the UAF or by the SUBMIT
command (if included).
2.34 - /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.
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.
Specify the value of n as a number of 512-byte pagelets on
Alpha or 512-byte pages on VAX. Note that the operating system
rounds up this value 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 the value 0 or NONE, the working set quota value
defaults to the value specified in the UAF or by the SUBMIT
command (if included).
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 size and working set quota values.
Value Specified Value

| 3 - Examples |
1.$ STOP/QUEUE LPA0
$ START/QUEUE/TOP_OF_FILE LPA0
The STOP/QUEUE command in this example suspends the job that is
currently executing on the printer queue LPA0 and places that
queue in the paused state. The START/QUEUE command releases the
queue from the paused state. The /TOP_OF_FILE qualifier causes
the job that was suspended to resume printing at the beginning
of the file rather than at where it was interrupted.
2.$ INITIALIZE/QUEUE LPA0
.
.
.
$ START/QUEUE/DEFAULT=FLAG LPA0
The INITIALIZE/QUEUE command in this example initializes the
queue named LPA0. Later, the START/QUEUE command starts the
queue. The /DEFAULT qualifier requests that a flag page precede
each file in each job.
3.$ START/QUEUE/DEFAULT=FORM=LN01_PORTRAIT LN01_PRINT
The START/QUEUE command in this example restarts the LN01_PRINT
queue with the default form LN01_PORTRAIT.
4.$ INITIALIZE/QUEUE/START/GENERIC=(A,B) MYQUEUE
.
. [new printers X and Y are brought in at a later date]
.
$ STOP/QUEUE/NEXT MYQUEUE
$ START/QUEUE/GENERIC=(X,Y) MYQUEUE
This example changes the list of target nodes for a generic
queue. Note that the queue was previously initialized as a
generic queue.
4 - /MANAGER
Starts the clusterwide queue manager for the queuing system
and opens that queue manager's queue database files. The /QUEUE
qualifier is optional, but the /MANAGER qualifier is required.
By default, the command affects the default queue manager,
SYS$QUEUE_MANAGER. Specify the /NAME_OF_MANAGER qualifier
to start a queue manager other than the default. For more
information, refer to the OpenVMS System Manager's Manual.
Requires OPER (operator) and SYSNAM (system logical name)
privileges.
Format
START/QUEUE/MANAGER [dirspec]
4.1 - Parameter
dirspec
Specifies the directory location to contain the system queue and
journal files of the queue database. The queue file has a file
type of QMAN$QUEUES and contains queue definitions. The journal
file has a file type of QMAN$JOURNAL and contains job and other
information that lets the queue manager to return to its last
known state should a system be stopped unexpectedly. These files
must reside in the same directory.
The default location of the queue and journal files is
SYS$COMMON:[SYSEXE]. The optional dirspec parameter is used
only for specifying an alternate location for the queue and
journal files. The specification must include at least the
device and directory name. The asterisk (*) and the percent
sign (%) wildcard characters are not allowed in the directory
specification.
The directory you specify must be available to all nodes that
can run the queue manager. If the directory specification is a
concealed logical name, it must be identically defined on all
nodes in the cluster.
The location of the queue and journal files is stored in the
master file of the queue database. You do not have to respecify
the directory location with subsequent START/QUEUE/MANAGER
commands.
For information about changing the location of any of the queue
database files, refer to the Guide to Maintaining a VMS System.
4.2 - Description
The START/QUEUE/MANAGER command has the following uses:
o Enter the command START/QUEUE/MANAGER/NEW_VERSION to create
the queue database and initially start a queue manager.
See the description of the /NEW_VERSION qualifier for more
information. Once the queue manager has been started, it
will remain running unless it is explicitly stopped with the
STOP/QUEUE/MANAGER/CLUSTER command.
o If the STOP/QUEUE/MANAGER/CLUSTER command has been executed,
enter the START/QUEUE/MANAGER command to restart a queue
manager.
o In an OpenVMS Cluster, enter the START/QUEUE/MANAGER command
with the /ON qualifier to modify the list of preferred nodes
on which a queue manager can run. See the description of the
/ON qualifier for more information.
o In an OpenVMS Cluster, enter the START/QUEUE/MANAGER command
to ensure that a queue manager process is executing on the
most preferred, available node. If the queue manager is not
running on the most preferred, available node, the queue
manager will be moved to that node without interruption of
service. If you are using the default node list (*), the
queue manager will not move. For more information, see the
description of the /ON qualifier.
If the queue manager is in a location other than the default, and
in OpenVMS Cluster environments with multiple system disks, you
must define the logical name QMAN$MASTER. For instructions, refer
to the chapter about the queue manager and queue database in the
OpenVMS System Manager's Manual.
If a queue manager does not start when you enter the
START/QUEUE/MANAGER command, you will receive the following
message:
%JBC-E-QMANNOTSTARTED, queue manager could not be started
If you see this message, search the operator log file
SYS$MANAGER:OPERATOR.LOG (or look on the operator console) for
messages from the facilities QUEUE_MANAGE and JOB_CONTROL for
information about the problem, as follows:
$ SEARCH SYS$MANAGER:OPERATOR.LOG /WINDOW=5 QUEUE_MANAGE,JOB_CONTROL
4.3 - Qualifiers
4. 3.1 - /ADD
Creates an additional queue manager in the existing queue
database. If the named queue manager already exists, the request
will be rejected.
4. 3.2 - /NAME_OF_MANAGER
/NAME_OF_MANAGER=name
Creates a non-default queue manager. The required name value may
be up to 31 characters long and may be a logical. The name will
serve as the identifier for the queue manager process and the
portion of the database that it is managing.
4. 3.3 - /NEW_VERSION
/NEW_VERSION
/NONEW_VERSION (default)
Specifies that a new (empty) version of the queue database is to
be created. This qualifier is required when initially creating
and starting the queuing system.
If you specify this qualifier and a queue database already
exists, the new master and queue files of the queue database
supersede existing versions of those files; however, the journal
file of the existing queue database is deleted. Jobs and other
information are lost.
4. 3.4 - /ON
/ON=(node[,...])
In an OpenVMS Cluster, specifies 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.
4.4 - Examples
1.$ START/QUEUE/MANAGER/NEW_VERSION
$ SHOW QUEUE
%JBC-E-NOSUCHQUE, no such queue
The START/QUEUE/MANAGER command in this example starts the
queue manager and creates the queue and journal files in the
default location, SYS$COMMON:[SYSEXE]. Because the asterisk
(*) wildcard character is used as the default value for the
list of nodes on which the queue manager can run, the queue
manager will be able to fail over to any available node in the
cluster.
This command starts the default queue manager SYS$QUEUE_MANAGER
because the /NAME_OF_MANAGER qualifier is not specified.
Both the SYS$COMMON:[SYSEXE] location and the asterisk value
for the /ON qualifier are stored in the queue database for
future reference. The newly created queue database contains no
queues or jobs. The SHOW QUEUE command shows that no queues are
defined on this cluster.
2.$ START/QUEUE/MANAGER/NEW_VERSION -
_$ /ON=(SATURN,VENUS,NEPTUN,*) DUA5:[SYSQUE]
The START/QUEUE/MANAGER command in this example creates the
queue and journal files on the cluster-accessible disk volume
DUA5, in directory SYSQUE. You must mount the disk before you
enter the START/QUEUE/MANAGER command.
The /ON qualifier specifies that the queue manager should run
first on node SATURN. If SATURN leaves the cluster, the queue
manager will attempt to fail over to VENUS. If VENUS is not
available, the queue manager will attempt to fail over to
NEPTUN. If NEPTUN is not available, the queue manager will
fail over to any other available node in the cluster.
3.$ START/QUEUE/MANAGER/NEW_VERSION -
_$ /ON=(SATURN,VENUS,NEPTUN,*) DUA5:[SYSQUE])
.
.
.
$ START/QUEUE/MANAGER
The START/QUEUE/MANAGER command in this example creates the
queue database as shown in the previous example. Suppose the
queue manager started on node SATURN.
Later, SATURN is removed from the cluster, and the queue
manager fails over to node VENUS. When SATURN rejoins the
cluster, the second START/QUEUE/MANAGER command in the example
is entered to move the queue manager back to node SATURN.
The second START/QUEUE/MANAGER command does not specify the
DUA5:[SYSQUE] parameter value or the /ON qualifier and its node
list because those previously supplied pieces of information
are stored in the queue database. The queue manager continues
to use the queue and journal files found at the location
stored in its database. The /ON list, stored as a result of the
previous START/QUEUE/MANAGER command, also remains unchanged.
4.$ START/QUEUE/MANAGER DUA4:[SYSQUE]
%JBC-E-QMANNOTSTARTED, queue manager could not be started
$ SEARCH SYS$MANAGER:OPERATOR.LOG /WINDOW=5 QUEUE_MANAGE,JOB_CONTROL
%%%%%%%%%%% OPCOM 14-DEC-2001 18:55:18.23 %%%%%%%%%%%
Message from user QUEUE_MANAGE on QMUNGR
%QMAN-E-OPENERR, error opening DUA4:[SYSQUE]SYS$QUEUE_MANAGER.QMAN$QUEUES;

Message from user QUEUE_MANAGE on QMUNGR
-SYSTEM-W-NOSUCHDEV, no such device available
$ START/QUEUE/MANAGER DUA5:[SYSQUE]
In this example, the first START/QUEUE/MANAGER command
specifies device DUA4: as the location of the queue and journal
files. The error message indicates that the queue manager does
not start. The SEARCH command searches the operator log file
for relevent messages, and reveals that device DUA4: does not
exist. The second START/QUEUE/MANAGER command specifies the
correct device name, DUA5:.
