HELP INITIALIZE — VMS 5.5
The INITIALIZE command performs the following functions:
o Formats a disk or magnetic tape volume and writes a label on
the volume (see Device).
o Creates or initializes queues (see /QUEUE).
Additional information available:
Device
Formats a disk or magnetic tape volume and writes a label on the
volume. At the end of initialization, the disk is empty except for
the system files containing the structure information. All former
contents of the disk are lost.
Requires VOLPRO (volume protection) privilege for most INITIALIZE
command operations.
Format
INITIALIZE device-name[:] volume-label
Additional information available:
PARAMETERS
device-name[:]
Specifies the name of the device on which the volume to be
initialized is physically mounted.
The device does not have to be allocated currently; however,
allocating the device before initializing it is the recommended
practice.
volume-label
Specifies the identification to be encoded on the volume. For
a disk volume, you can specify a maximum of 12 alphanumeric
characters; for a magnetic tape volume, you can specify a maximum
of 6 alphanumeric characters. Letters are automatically changed
to uppercase. Nonalphanumeric characters are not allowed in the
volume-label specification on disk.
To use ANSI "a" characters on the volume label on magnetic tape,
you must enclose the volume name in quotation marks (" "). For
an explanation of ANSI "a" characters, see the description of the
/LABEL qualifier.

/WINDOWS
/ACCESSED
/ACCESSED=number-of-directories
Affects Files-11 On-Disk Structure Level 1 disks only.
Specifies, for disk volumes, the number of directories allowed in
system space must be a value from 0 to 255. The default value
is 3.
/BADBLOCKS
/BADBLOCKS=(area[,...])
Specifies, for disk volumes, faulty areas on the volume. The
INITIALIZE command marks the areas as allocated so that no data is
written in them.
Possible formats for area are as follows:
lbn[:count] Logical block number (LBN) of the first block
and optionally a block count beginning with the
first block, to be marked as allocated
sec.trk.cyl[:cnt] Sector, track, and cylinder of the first block,
and optionally a block count beginning with the
first block, to be marked as allocated
All media supplied by Digital and supported on the VMS operating
system, except diskettes and TU58 cartridges, are factory
formatted and contain bad block data. The Bad Block Locator
Utility (BAD) or the diagnostic formatter EVRAC can be used
to refresh the bad block data or to construct it for the media
exceptions above. The /BADBLOCKS qualifier is necessary only to
enter bad blocks that are not identified in the volume's bad block
data.
Digital Storage Architecture (DSA) disks (for example, disks
attached to UDA-50 and HSC50 controllers) have bad blocks handled
by the controller, and appear logically perfect to the file
system.
For information on how to run BAD, see the VMS Bad Block Locator
Utility Manual.
/CLUSTER_SIZE
/CLUSTER_SIZE=number-of-blocks
Defines, for disk volumes, the minimum allocation unit in blocks.
The maximum size you can specify for a volume is one-hundredth the
size of the volume; the minimum size you can specify is calculated
with the following formula:
disk_size(number_of_blocks)
255*4096
For Files-11 On-Disk Structure Level 2 disks, the cluster size
default depends on the disk capacity; disks that are 50,000 blocks
or larger have a default cluster size of 3, while those smaller
than 50,000 blocks have a default value of 1.
For Files-11 On-Disk Structure Level 1 disks, the cluster size
must always be 1.
/DATA_CHECK
/DATA_CHECK[=(option[,...])]
Checks all read and write operations on the disk. By default,
no data checks are made. Specify one or both of the following
options:
READ Checks all read operations.
WRITE Checks all write operations; default if only the /DATA_
CHECK qualifier is specified.
To override the checking you specify at initialization for disks,
enter a MOUNT command to mount the volume.
/DENSITY
/DENSITY=density-value
The /DENSITY qualifier is not applicable to the TK50 tape device.
For diskette volumes that are to be initialized on RX02 or RX33
diskette drives, specifies the density at which the diskette is to
be formatted.
RX02 dual-density diskette drives allow diskettes to be
initialized at single or double density. RX33 diskette drives
allow diskettes to be initialized at double density only. To
specify single-density formatting of a diskette, specify the
density value SINGLE. To specify double-density formatting of
a diskette, specify the density value DOUBLE.
If you do not specify a density value for a diskette being
initialized on a drive, the system leaves the volume at the
density to which the volume was last formatted.
For magnetic tape volumes, specifies the density in bits per inch
(bpi) at which the magnetic tape is to be written.
For magnetic tape volumes, the density value specified can be 800
bpi, 1600 bpi, or 6250 bpi, as long as the density is supported
by the magnetic tape drive. If you do not specify a density value
for a blank magnetic tape, the system uses a default density of
the highest value allowed by the tape drive. If the drive allows
6250-, 1600-, and 800-bpi operation, the default density is 6250
bpi. If you do not specify a density value for a magnetic tape
that has been previously written, the system uses the density of
the first record on the volume. If the record is unusually short,
the density value will not default.
NOTE
Diskettes formatted in double density cannot be read or
written by the console block storage device (an RX01 drive)
of a VAX/780 until they have been reformatted in single
density.
RX33 diskettes cannot be read or written by RX50 disk
drives. RX50 diskettes can be read and written by RX33 disk
drives; they cannot be formatted by RX33 disk drives.
/DIRECTORIES
/DIRECTORIES=number-of-entries
Specifies, for disk volumes, the number of entries to preallocate
for user directories. The number of entries must be an integer
between 16 and 16000. The default value is 16.
/ERASE
/ERASE
/NOERASE (default)
Physically destroys deleted data by writing over it. Controls
the data security erase (DSE) operation on the volume before
initializing it. The /ERASE qualifier applies to Files-11 On-
Disk Structure Level 2 disk and ANSI magnetic tape volumes, and is
valid for magnetic tape devices that support the hardware erase
function, such as TU78 and MSCP magnetic tapes.
If you specify the /ERASE qualifier, a DSE operation is performed
on the volume. For disk devices, the ERASE volume attribute is
set. In effect, each file on the volume is erased when it is
deleted.
Note that the amount of time taken by the DSE operation depends
on the volume size; the INITIALIZE/ERASE command is always slower
than the INITIALIZE/NOERASE command.
/EXTENSION
/EXTENSION=number-of-blocks
Specifies, for disk volumes, the number of blocks to use as a
default extension size for all files on the volume. The extension
default is used when a file increases to a size greater than its
initial default allocation during an update. For Files-11 On-
Disk Structure Level 2 disks, the value for the number-of-blocks
parameter can range from 0 to 65,535. The default value is 5. For
Files-11 On-Disk Structure Level 1 disks, the value can range from
0 to 255.
In VMS, the default volume extension is used only if no different
extension has been set for the file and no default extension has
been set for the process by using the SET RMS command.
/FILE_PROTECTION
/FILE_PROTECTION=code
Affects Files-11 On-Disk Structure Level 1 disks only.
Defines, for disk volumes, the default protection to be applied to
all files on the volume.
Specify the code according to the standard syntax rules described
in the VMS DCL Concepts Manual. Any attributes not specified are
taken from the current default protection.
Note that this attribute is not used when the volume is being used
on a VMS system, but is provided to control the process's use of
the volume on RSX-11M systems. VMS systems always use the default
file protection. Use the SET PROTECTION/DEFAULT command to change
the default file protection.
/GROUP
Defines a group volume. The /GROUP qualifier applies protection of read (R), write (W), execute (E), and delete (D) access to all ownership categories unless the /GROUP qualifier is specified with the /NOSHARE qualifier, in which case the volume protection is RWED for all but the world category. The owner user identification code (UIC) of the volume defaults to your group number and a member number of 0.
/HEADERS
/HEADERS=number-of-headers
Specifies, for disk volumes, the number of file headers to be
allocated for the index file. The minimum and default value is 16.
The maximum is the value set with the /MAXIMUM_FILES qualifier.
This qualifier is useful when you want to create a number of files
and want to streamline the process of allocating space for that
number of file headers. If you do not specify this qualifier, the
file system dynamically allocates space as it is needed for new
headers on the volume.
/HIGHWATER
/HIGHWATER (default)
/NOHIGHWATER
Affects Files-11 On-Disk Structure Level 2 disks only.
Sets the file highwater mark (FHM) volume attribute, which
guarantees that a user cannot read data that the user has not
written. You cannot specify the /NOHIGHWATER qualifier for
magnetic tape.
The /NOHIGHWATER qualifier disables FHM for a disk volume.
/INDEX
/INDEX=position
Specifies the location of the index file for the volume's
directory structure. Possible positions are as follows:
BEGINNING Beginning of the volume
MIDDLE Middle of the volume (default)
END End of the volume
BLOCK:n Beginning of the logical block specified by n
/LABEL
/LABEL=option
Defines characteristics for the magnetic tape volume label, as
directed by the included option. The available options are as
follows:
o OWNER_IDENTIFIER:"(14 ANSI characters)"
Allows you to specify the Owner Identifier field in the volume
label. The field specified can accept up to 14 ANSI characters.
o VOLUME_ACCESSIBILITY:"character"
Specifies the character to be written in the volume
accessibility field of the VMS ANSI volume label VOL1 on an
ANSI magnetic tape. The character may be any valid ANSI "a"
character. This set of characters includes numeric characters,
uppercase letters, and any one of the following nonalphanumeric
characters:
! " % ' ( ) * + , - . / : ; < = > ?
By default, the VMS operating system provides a routine that
checks this field in the following manner:
o If the magnetic tape was created on a version of the VMS
operating system that conforms to Version 3 of ANSI, then
this option must be used to override any character other
than an ASCII space.
o If a VMS protection is specified and the magnetic tape
conforms to an ANSI standard that is later than Version
3, then this option must be used to override any character
other than an ASCII 1.
If you specify any character other than the default, you must
specify the /OVERRIDE=ACCESSIBILITY qualifier on the INITIALIZE
and MOUNT commands in order to access the magnetic tape.
/MAXIMUM_FILES
/MAXIMUM_FILES=n
Restricts the maximum number of files that the volume can contain.
The /MAXIMUM_FILES qualifier overrides the default value, which is
calculated as follows:
_volume_size_in_blocks
(cluster factor+1)*2
The maximum size you can specify for any volume is as follows:
volume_size_in_blocks
(cluster factor+1)
The minimum value is 0. Note that the maximum can be increased
only by reinitializing the volume.
NOTE
The MAXIMUM_FILES qualifier does not reserve or create
space for new file headers on a volume. The file system
dynamically allocates space as it is needed for new headers.
/MEDIA_FORMAT
/MEDIA_FORMAT=[NO]COMPACTION
Controls whether data records are automatically compacted and
blocked together on DSA and SCSI tapes drives that support data
compaction. Data compaction and record blocking increase the
amount of data that can be stored on a single tape cartridge.
Note that once data compaction or non-compaction has been selected
for a given cartridge, that same status applies to the entire
cartridge.
/OVERRIDE
/OVERRIDE=(option[,...])
Requests the INITIALIZE command to ignore data on a magnetic tape
volume that protects it from being overwritten. You can specify
one or more of the following options:
ACCESSIBILITY (For magnetic tapes only.) If the installation
allows, this option overrides any character
in the Accessibility field of the volume. The
necessity of this option is defined by the
installation. That is, each installation has
the option of specifying a routine that the
magnetic tape file system will use to process
this field. By default, VMS provides a routine
that checks this field in the following manner.
If the magnetic tape was created on a version
of VMS that conforms to Version 3 of ANSI, this
option must be used to override any character
other than an ASCII space. If a VMS protection
is specified and the magnetic tape conforms to
an ANSI standard that is higher than Version
3, this option must be used to override any
character other than an ASCII 1. To use the
ACCESSIBILITY option, you must have the user
privilege VOLPRO or be the owner of the volume.
EXPIRATION (For magnetic tapes only.) Allows you to
write to a tape that has not yet reached its
expiration date. You may need to do this for
magnetic tapes that were created before VMS
Version 4.0 on Digital operating systems using
the D% format in the volume Owner Identifier
field. You must have the user privilege VOLPRO
to override volume protection, or your UIC must
match the UIC written on the volume.
OWNER_IDENTIFIER Allows you to override the processing of the
Owner Identifier field of the volume label.
If you specify only one option, you can omit the parentheses.
To initialize a volume that was initialized previously with the
/PROTECTION qualifier, your UIC must match the UIC written on the
volume or you must have VOLPRO privilege.
/OWNER_UIC
/OWNER_UIC=uic
Specifies an owner user identification code (UIC) for the volume.
The default is your default UIC. Specify the UIC using standard
UIC format as described in the VMS DCL Concepts Manual.
For magnetic tapes, no UIC is written unless protection on the
magnetic tape is specified. If protection is specified, but no
owner UIC is specified, your current UIC is assigned ownership of
the volume.
/PROTECTION
/PROTECTION=(ownership[:access][,...])
Applies the specified protection to the volume. Specify ownership
as system (S), owner (O), group (G), or world (W) and access as
read (R), write (W), execute (E), or delete (D). The default is
your default protection. Note that the /GROUP, /SHARE, and /SYSTEM
qualifiers can also be used to define protection for disk volumes.
For magnetic tape, the protection code is written to a VMS-
specific volume label. The system only applies read (R) and write
(W) access restrictions; execute (E) and delete (D) access are
meaningless. Moreover, the system and the owner are always given
both read (R) and write (W) access to magnetic tapes, regardless
of the protection code you specify.
For more information on specifying protection code, see the VMS
DCL Concepts Manual. Any attributes not specified are taken from
the current default protection.
When you specify a protection code for an entire disk volume, the
access type E (execute) indicates create access.
/SHARE
/SHARE (default)
/NOSHARE
Permits all categories of access by all categories of ownership.
The /NOSHARE qualifier denies access to group (unless the /GROUP
qualifier is also specified) and world processes.
/STRUCTURE
/STRUCTURE=level
Specifies whether the volume should be formatted in Files-11 On-
Disk Structure Level 1 or 2 (the default). On-Disk Structure
Level 1 is incompatible with the /DATA_CHECK and /CLUSTER_SIZE
qualifiers. The default protection for an On-Disk Structure Level
1 disk is full access to system, owner, and group, and read (R)
access to all other users.
/SYSTEM
Requires a system UIC or SYSPRV (system privilege) privilege. Defines a system volume. The owner UIC defaults to [1,1]. Protection defaults to complete access by all ownership categories, except that only system processes can create top-level directories.
/USER_NAME
/USER_NAME=name
Specifies a user name to be associated with the volume. The name
must be 1 to 12 alphanumeric characters. The default is your user
name.
/VERIFIED
/VERIFIED
/NOVERIFIED
Indicates whether the disk has bad block data on it. Use the
/NOVERIFIED qualifier to ignore bad block data on the disk. The
default is the /VERIFIED qualifier for disks with 4096 blocks or
more and the /NOVERIFIED qualifier for disks with less than 4096
blocks.
/WINDOWS
/WINDOWS=n
Specifies the number of mapping pointers (used to access data in
the file) to be allocated for file windows. The value can be an
integer in the range of 7 to 80. The default is 7.
Examples
1. $ INITIALIZE/USER_NAME=CPA $FLOPPY1 ACCOUNTS
Initializes the volume on $FLOPPY1, labels the volume ACCOUNTS,
and gives the volume a user name of CPA.
2. $ ALLOCATE DMA2: TEMP
_DMA2: ALLOCATED
$ INITIALIZE TEMP: BACK_UP_FILE
$ MOUNT TEMP: BACK_UP_FILE
%MOUNT-I-MOUNTED, BACK_UP_FILE mounted on _DMA2:
$ CREATE/DIRECTORY TEMP:[ARCHIE]
The previous sequence of commands shows how to initialize an
RK06/RK07 volume. First, the device is allocated, to ensure
that no one else can access it. Then, when the volume is
physically mounted on the device, the INITIALIZE command
initializes it. When the volume is initialized, the MOUNT
command makes the file structure available. Before you can
place any files on the volume, you must create a directory, as
shown by the CREATE/DIRECTORY command.
3. $ ALLOCATE MT:
_MTB1: ALLOCATED
$ INITIALIZE MTB1: SOURCE
$ MOUNT MTB1: SOURCE
%MOUNT-I-MOUNTED, SOURCE mounted on _MTB1:
$ COPY *.FOR MTB1:
$ DIRECTORY MTB1:
.
.
.
$ DISMOUNT MTB1:
These commands show the procedure necessary to initialize a
magnetic tape. After allocating a drive, the magnetic tape is
loaded on the device, and the INITIALIZE command writes the
label SOURCE on it. Then, the MOUNT command mounts the magnetic
tape so that files can be written on it.
4. $ BACKUP filespec MUA0: ... /MEDIA_FORMAT=NOCOMPACTION-
_$/REWIND
This example creates a BACKUP tape with compaction and record
blocking disabled.
/QUEUE
Creates or initializes queues. You use this command to create
queues and to assign them names and attributes. The /QUEUE
qualifier is required. The /BATCH qualifier is required to create
a batch queue.
Requires OPER (operator) privilege.
Format
INITIALIZE/QUEUE queue-name[:]
Additional information available:
Parameter
queue-name[:] Specifies the name of an execution queue or a generic queue. The queue name may be a string of 1 to 31 characters. The character string can include any uppercase and lowercase letters, digits, the dollar sign ($), and the underscore (_), and must include at least one alphabetic character.

/RECORD_BLOCKING/RETAIN/SCHEDULE/SEPARATE/START
/WSDEFAULT/WSEXTENT/WSQUOTA
/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.
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 make the queue an autostart queue.
For more information about autostart queues, see the
Guide to Maintaining a VMS System.
/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.
/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 or generic
queue. By default, the /BATCH qualifier initializes an execution
queue. To specify a generic batch queue, use the /GENERIC
qualifier together with the /BATCH qualifier.
The /BATCH and /DEVICE qualifiers are mutually exclusive; the
/NOBATCH and /NODEVICE qualifiers cannot be used together.
/BLOCK_LIMIT
/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 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 that queue.
/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.
/CLOSE
Prevents jobs from being entered in the queue through PRINT or SUBMIT commands or as a result of requeue operations. To allow jobs to be entered, use the /OPEN qualifier. Whether a queue accepts or rejects new job entries is independent of the queue's state (such as paused, stopped, or stalled). When a queue is marked closed, jobs executing continue to execute. Jobs pending in the queue continue to be candidates for execution.
/CPUDEFAULT
/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 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 or the VMS User's
Manual.
/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 SYSGEN parameter PQL_MCPULM.
For information on specifying delta times, see the VMS DCL
Concepts Manual or the VMS User's Manual.
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.

/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. 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 attributes, see
the description of the /SEPARATE qualifier. For information on
specifying default queue attributes, see the Guide to Maintaining
a VMS System.
/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.
/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.
/DISABLE_SWAPPING
/DISABLE_SWAPPING
/NODISABLE_SWAPPING (default)
Controls whether batch jobs executed from a queue can be swapped
in and out of memory.
/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.
/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 /DEFAULT=FORM qualifier, 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 is not identical to the
stock of the mounted form, the job enters a pending state. In both
cases, jobs remain pending until the stock of the mounted form of
the queue is identical to the stock of the form associated with
the job.
To specify the form type, use either a numeric value or a form
name that has been defined by the DEFINE/FORM command. Form
types are installation specific. You cannot use the /FORM_MOUNTED
qualifier with the /GENERIC qualifier.
/GENERIC
/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.
/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 0 to
255. The job limit default value for n is 1.
/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. 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.
/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 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
/OPEN (default)
Allows jobs to be entered in the queue through PRINT or SUBMIT
commands or as the result of requeue operations. To prevent jobs
from being entered in the queue, use the /CLOSE qualifier. Whether
a queue accepts or rejects new job entries is independent of the
queue's state (such as paused, stopped, or stalled).
/OWNER_UIC
/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 VMS DCL Concepts Manual. The default UIC is [1,4].
/PROCESSOR
/PROCESSOR=file-name
/NOPROCESSOR
Allows you to specify your own print symbiont for an output
execution queue. You can use any valid file name as a parameter
of the /PROCESSOR qualifier. The system supplies the device and
directory name SYS$SYSTEM and the file type EXE. If you use this
qualifier for an output queue, it specifies that the symbiont
image to be executed is SYS$SYSTEM:filename.EXE.
By default, SYS$SYSTEM:PRTSMB.EXE is the symbiont image associated
with an output execution queue.
The /NOPROCESSOR qualifier cancels any previous setting
established with the /PROCESSOR qualifier and causes
SYS$SYSTEM:PRTSMB.EXE to be used.
/PROTECTION
/PROTECTION=(ownership[:access],...)
Specifies the protection of the queue. Specify the ownership
parameter as system (S), owner (O), group (G), or world (W)
and the access parameter as read (R), write (W), execute (E),
or delete (D). A null access specification means no access. The
default protection is: (SYSTEM:E, OWNER:D, GROUP:R, WORLD:W).
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 (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 VMS print symbiont, record blocking can
have a significant performance advantage over single-record mode.
/RETAIN
/RETAIN[=option]
/NORETAIN (default)
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 (default) Holds all jobs in the queue after execution.
ERROR Holds in the queue only jobs that complete
unsuccessfully.
/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 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.
/SEPARATE
/SEPARATE=(option[,...])
/NOSEPARATE (default)
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 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 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.
/START
/START
/NOSTART (default)
Starts the queue being initialized by the current INITIALIZE/QUEUE
command.
/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.
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
included).
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.
/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.
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
included).
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.
/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. 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 included).
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. These are the actions taken for different
combinations of specifications that involve working set values.

Examples
1. $ 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 2000 blocks.
2.
$ 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. Thus only print
jobs larger than 1000 blocks can execute on that queue.
SYS$PRINT is established as a generic queue that can direct jobs
to either LPA0_PRINT or LPB0_PRINT. Jobs that are too small to
run on LPB0_PRINT will be queued from SYS$PRINT to LPA0_PRINT.
The last INITIALIZE/QUEUE command sets up a terminal queue on
TXA5. A job queued with a form that has a stock type other
than the stock type of form LETTER remains pending in the
queue until a form with the same stock type is mounted on the
queue, or until the entry is deleted from the queue or moved
to another queue. LETTER has been established at this site to
indicate special letterhead paper. The block size limit is 50,
indicating that this queue is reserved for jobs smaller than
51 blocks.
