HELP START — VMS 5.5-2H4
o Start the secondary processor or processors (and any associated
vector processors) in a VMS multiprocessing system. (see /CPU).
o Start the system job queue (see /QUEUE).
o Start the system job queue manager (see /QUEUE /MANAGER).
o Add a zone to a running VAXft (see /ZONE).
Additional information available:
/CPU
Starts the specified secondary processor or processors (and any
associated vector processors) in a VMS multiprocessing system. The
/CPU qualifier is required.
Applies only to VMS multiprocessing systems. Requires CMKRNL
(change mode to kernel) privilege.
Format
START/CPU [cpu-id[,...]]
Additional information available:
Parameter
cpu-id[,...] Specifies a decimal value representing the identity of a processor in a VMS multiprocessing system. In a VAX 8300 system, for instance, the CPU ID is the VAXBI node number of the processor; in a VAX 8800, the CPU ID of the left processor is 1 and that of the right processor is 0. If you do not specify a CPU ID and do not include the /ALL qualifier, the START/CPU command selects a single available processor to join the multiprocessing system.
Description
The START/CPU command starts a secondary processor in a VMS multiprocessing system. You can issue a START/CPU command only for processors in the STOPPED or TIMOUT state, as represented by the SHOW CPU command. Otherwise, the START/CPU command has no effect.
QUALIFIER
Additional information available:
/ALL
Selects all remaining processors in the system's available set to join the multiprocessing system.
Examples
1. $ START/CPU
The START/CPU command in this example selects a single inactive
processor from the set of those processors that are currently
available but inactive. When it completes its initialization,
the selected processor becomes part of the system's active set
and is capable of scheduling and executing processes.
2. $ START/CPU 4,7
The START/CPU command in this example selects the processors
with CPU IDs 4 and 7, if they are currently available and
inactive. When they complete initialization, these processors
become part of the system's active set and are capable of
scheduling and executing processes.
3. $ START/CPU/ALL
The START/CPU/ALL command in this example selects all
remaining inactive and available processors. When they
complete initialization, these processors become part of the
system's active set and are capable of scheduling and executing
processes.
/QUEUE
Starts or restarts the specified queue after it has been
initialized. You also can use this command to change the
attributes of the specified queue. The /QUEUE qualifier is
required.
Requires OPER (operator) privilege or execute (E) access to the
specified queue.
Format
START/QUEUE queue-name[:]
Additional information available:
PARAMETER
queue-name[:] Specifies the name of the queue to be started or restarted.
QUALIFIERS

/PROTECTION/RECORD_BLOCKING/RETAIN/SCHEDULE
/SEARCH/SEPARATE/TOP_OF_FILE/WSDEFAULT/WSEXTENT
/WSQUOTA
/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 are 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 are
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.
/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 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.
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, see the
Guide to Maintaining a VMS System.
/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.
/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.
/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 two consecutive quotation
marks ("") 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.
/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 /CHARACTERISITCS qualifier for the 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 already pending in the queue continue to be candidates for execution.
/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 SYSGEN
parameter PQL_MCPULM.
For information on specifying delta times, see the VMS DCL
Concepts Manual.
/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 SYSGEN parameter PQL_MCPULM. The time
cannot exceed the CPU time limit set by the /CPUMAXIMUM qualifier.
For information on specifying delta time, see the VMS DCL Concepts
Manual.
/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. For information on establishing mandatory
queue attributes, see the description of the /SEPARATE 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.
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 specifying
default queue attributes, see the Guide to Maintaining a VMS
System.
/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.
/DISABLE_SWAPPING
/DISABLE_SWAPPING
/NODISABLE_SWAPPING
Controls whether batch jobs executed from a queue can be swapped
in and out of memory.
/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.
/FORM_MOUNTED
/FORM_MOUNTED=type
Specifies the mounted form for an output execution queue. If
the stock of the mounted form does not match the stock of the
default form, as indicated by the qualifier /DEFAULT=FORM, all
jobs submitted to this queue without an explicit form definition
enter a pending state. If a job is submitted with an explicit form
and the stock of the explicit form does not match the stock of the
mounted form, the job enters a pending state. In both cases, the
jobs remain in a pending state until the stock of the mounted form
of the queue matches 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.
/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.
/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.
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.
/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.
/LIBRARY
/LIBRARY=file-name
/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$LIBRARY
and that the file type is TLB.
/NEXT
Aborts the currently suspended print job and begins processing of the first pending job in the queue. Use this qualifier only when restarting an output execution queue from a paused state.
/ON
/ON=[node::]device[:] (printer, terminal, server queue)
/ON=node:: (batch queue)
Specifies the node or device, or both, on which this execution
queue is located. For batch execution queues, you can specify only
the node name. For output execution queues, you can include both
the node name and the device name.
The node name is used only in VAXcluster systems; it must match
the node name specified by the SYSGEN parameter SCSNODE for the
VAX computer on which the queue executes.
/OPEN
Allows jobs to be entered in the queue through PRINT or SUBMIT commands or as the result of requeue operations. To prevent jobs from being entered in the queue, use the /CLOSE qualifier. Whether a queue accepts or rejects new job entries is independent of the queue's state (such as paused, stopped, or stalled).
/OWNER_UIC
/OWNER_UIC=uic
Requires OPER (operator) privilege or control (C) and execute
(E) access to the queue.
Enables you to change the user identification code (UIC) of the
queue. Specify the UIC by using standard format as described in
the VMS DCL Concepts Manual.
/PROCESSOR
/PROCESSOR=filename
/NOPROCESSOR
Allows you to specify your own print symbiont for an output
execution queue. You can use any valid file name as a parameter
of the /PROCESSOR qualifier. The system supplies the device and
directory name SYS$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 by the /PROCESSOR qualifier, and causes
SYS$SYSTEM:PRTSMB.EXE to be used.
/PROTECTION
/PROTECTION=(ownership[:access],...)
Requires OPER (operator) privilege or control (C) and execute
(E) access to the queue.
Specifies the protection of the queue. Ownership categories are
system (S), owner (O), group (G), and world (W); each category
can be abbreviated to its first character. Access categories are
read (R), write (W), execute (E), and 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, see the VMS DCL Concepts Manual. For
more information on controlling queue operations through UIC-based
protection, see the Guide to Maintaining a VMS System.
/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 VMS print symbiont, record blocking can
have a significant performance advantage over single-record mode.
/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.
/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.
/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.
/SEPARATE
/SEPARATE=(option[,...])
/NOSEPARATE
Specifies the mandatory queue attributes, 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 attributes that can be
overridden, see the description of the /DEFAULT qualifier.
For more information on specifying mandatory queue attributes, see
the Guide to Maintaining a VMS System.
/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.
/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.
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).
/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.
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).
/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.
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.
Decision Table - Working Set Default, Extent, and Quota Decision

UAF value; use the smaller.
Examples
1. $ STOP/QUEUE LPA0
$ START/QUEUE/TOP_OF_FILE LPA0
The STOP/QUEUE command in this example suspends operation
of the printer queue LPA0. Then the START/QUEUE/TOP_OF_FILE
command resumes operation. The file that was being printed when
the queue was stopped is started again from the beginning.
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.
/MANAGER
Starts the clusterwide queue manager for the batch and print
queuing system and opens the queue database. The /QUEUE qualifier
is optional, but the /MANAGER qualifier is required.
For more information, see the Guide to Maintaining a VMS System.
Requires both OPER (operator) and SYSNAM (system logical name)
privileges.
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 the 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 the queue
manager.
o In a VAXcluster, enter the START/QUEUE/MANAGER command with
the /ON qualifier to modify the list of preferred nodes on
which the queue manager can run. See the description of the /ON
qualifier for more information.
o In a VAXcluster, enter the START/QUEUE/MANAGER command to
ensure that the 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 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$MANAGER:OPERATOR.LOG /WINDOW=5 QUEUE_MANAGE,JOB_CONTROL
Format
START/QUEUE/MANAGER [dirspec]
Additional information available:
PARAMETER
dirspec Specifies the directory location to contain the system queue and journal files of the queue database. The queue file, SYS$QUEUE_MANAGER.QMAN$QUEUES, contains queue definitions. The journal file, SYS$QUEUE_MANAGER.QMAN$JOURNAL, contains job and other information that lets the queue manager to return to its last known state should a system be stopped unexpectedly. These files must reside in the same directory. The default location of the queue and journal files is SYS$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. 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, see the Guide to Maintaining a VMS System.
Qualifiers
Additional information available:
/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.
/ON
/ON=(node[,...])
In a VAXcluster, specify the nodes on which the 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
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. You cannot specify
the asterisk wildcard 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.
Examples
1. $ START/QUEUE/MANAGER/NEW_VERSION
$ SHOW QUEUE
%JBC-E-NOSUCHQUE, no such queue
The START/QUEUE/MANAGER command in this example creates
the queue and journal files in the default location,
SYS$COMMON:[SYSEXE]. Because the asterisk (*) wildcard
character is used as the default value for the list of nodes
on which the queue manager can run, the queue manager will be
able to fail over to any available node in the cluster.
Both the SYS$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.

$ 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:.
