Formats a disk or magnetic tape volume, writes a label on the
volume, and leaves the disk 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
| 1 - 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 ANSI characters;
for a magnetic tape volume, you can specify a maximum of 6
alphanumeric characters. Letters are automatically changed to
uppercase. Compaq strongly recommends that a disk volume label
should only consist of alphanumeric characters, dollar signs ($),
underscores (_), and hyphens (-).
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.
| 2 - Description |
The default format for disk volumes in the OpenVMS operating
system is called the Files-11 On-Disk Structure Level 2. The
default for magnetic tape volumes is based on Level 3 of the
ANSI standard for magnetic tape labels and file structure for
informational interchange (ANSI X3.27-1978).
The INITIALIZE command can also initialize disk volumes in the
Files-11 On-Disk Structure Level 1 format.
You must have VOLPRO privilege to initialize a volume, except in
the following cases:
o A blank disk or magnetic tape volume; that is, a volume that
has never been written
o A disk volume that is owned by your current user
identification code (UIC) or by the UIC [0,0]
o A magnetic tape volume that allows write (W) access to your
current UIC that was not protected when it was initialized
After the volume is initialized and mounted, the SET SECURITY
command may be used to modify the security profile. When you
initialize a disk volume, the caching attribute of its root
directory (000000.DIR;1) is set to write-through. This means
that by default, all the files and directories that you create in
the volume will inherit a caching attribute of write-through. To
change the caching attribute, use the SET FILE command with the
/CACHING_ATTRIBUTE qualifier.
When the INITIALIZE command initializes a magnetic tape volume,
it always attempts to read the volume. A blank magnetic tape can
sometimes cause unrecoverable errors, such as the following:
o An invalid volume number error message:
%INIT-F-VOLINV, volume is invalid
o A runaway magnetic tape (this frequently occurs with new
magnetic tapes that have never been written or that have
been run through verifying machines). You can stop a runaway
magnetic tape only by setting the magnetic tape drive off line
and by then putting it back on line.
If this type of unrecoverable error occurs, you can initialize
a magnetic tape successfully by repeating the INITIALIZE command
from an account that has VOLPRO (volume protection) privilege and
by specifying the following qualifier in the command:
/OVERRIDE=(ACCESSIBILITY,EXPIRATION)
This qualifier ensures that the INITIALIZE command does not
attempt to verify any labels on the magnetic tape.
If you have VOLPRO privilege, the INITIALIZE command initializes
a disk without reading the ownership information. If you do
not have VOLPRO privilege, the INITIALIZE command checks the
ownership of the volume before initializing the disk. A blank
disk or a disk with an incorrect format can sometimes cause a
fatal drive error. If a blank disk or a disk with an incorrect
format causes this type of error, you can initialize a disk
successfully by repeating the INITIALIZE command with the
/DENSITY qualifier from an account that has VOLPRO privilege.
Many of the INITIALIZE command qualifiers allow you to specify
parameters that can maximize input/output (I/O) efficiency.
| 3 - Qualifiers |
3.1 - /ACCESSED
/ACCESSED=number-of-directories
Affects Files-11 On-Disk Structure Level 1 disks only.
Specifies that, for disk volumes, the number of directories
allowed in system space must be a value from 0 to 255. The
default value is 3.
3.2 - /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 Compaq and supported on the OpenVMS
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, refer to the OpenVMS Bad Block
Locator Utility Manual (available on the Documentation CD-ROM).
3.3 - /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 16382 blocks, or
1/50th the volume size, whichever is smaller.
For Files-11 On-Disk Structure Level 5 (ODS-5) disks, the default
cluster size is 3. In this case the minimum value allowed by the
following equation is applied:
(disk size in number of blocks)/(65535 * 4096)
Any fractional values must be rounded up to the nearest integer.
For Files-11 On-Disk Structure Level 2 (ODS-2) disks, the default
cluster size depends on the disk capacity; disks with less
than 50,000 have a default of 1. Disks that are larger than
50,000 have a default of either 3 or the result of the following
formula, whichever is greater:
(disk size in number of blocks)/(255 * 4096)
Any fractional values must be rounded up to the nearest integer.
For Files-11 On-Disk Structure Level 1 (ODS-1) disks, the cluster
size must always be 1.
NOTE
For Version 7.2, you can specify a cluster size for ODS-2
volumes smaller than allowed by the ODS-2 formula; however,
if you try to mount this volume on a system running a
version prior to 7.2, the mount fails with the following
error:
%MOUNT-F-FILESTRUCT, unsupported file structure level
If you choose the default during the initialization of a
Files-11 On-Disk Structure Level 2 (ODS-2) disk, your disk
can be mounted on prior versions of OpenVMS.
3.4 - /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.
3.5 - /DENSITY
/DENSITY=density-value
Allows you to specify the format density value for certain tapes
and disks.
For magnetic tape volumes, specifies the density in bits per inch
(bpi) at which the magnetic tape is to be written. 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.
The /DENSITY qualifier does not apply to any TF tape device.
Valid tape density values are:
Keyword Meaning
DEFAULT Default density
800 NRZI 800 bits per inch (BPI)
1600 PE 1600 BPI
6250 GRC 6250 BPI
3480 IBM 3480 HPC 39872 BPI
3490E IBM 3480 compressed
833 DLT TK50: 833 BPI
TK50 DLT TK50: 833 BPI
TK70 DLT TK70: 1250 BPI
6250 RV80 6250 BPI EQUIVALENT
NOTE: Only the keywords above are understood by TMSCP/TUDRIVER
code prior to OpenVMS Version 7.2. The remaining keywords
in this table are supported only on Alpha systems.

DDS4 Digital Data Storage 4 - Alpha only
AIT1 Sony Advanced Intelligent Tapes - Alpha only
To format a diskette on RXnn diskette drives, use the
INITIALIZE/DENSITY command. Specify the density at which the
diskette is to be formatted as follows:
Keyword Meaning
single RX01 - 8 inch
double RX02 - 8 inch
dd double density: 720K - 3 1/2 inch
hd high density: 1.44MB - 3 1/2 inch
ed extended density: 2.88MB - 3 1/2 inch
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.
NOTE
Diskettes formatted in double density cannot be read or
written by the console block storage device (an RX01 drive)
of a VAX-11/780 until they have been reformatted in single
density.
RX33 diskettes cannot be read from or written to by RX50
disk drives. RX50 diskettes can be read from and written to
by RX33 disk drives; they cannot be formatted by RX33 disk
drives.
3.6 - /DIRECTORIES
/DIRECTORIES=number-of-entries
The effect of this qualifier depends on the disk structure:
o For ODS-1, /DIRECTORIES allows space for the specified number
of directory entries to be reserved in 000000.DIR (the MFD).
o For ODS-2 and ODS-5, /DIRECTORIES allows the initial size of
the MFD to be set. The specified number is divided by 16, to
produce the number of blocks to preallocate. This number is
then rounded up to a whole number of clusters.
The number-of-entries value must be an integer between 16 and
16000. The default value is 16.
3.7 - /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 and 5 disks 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.
3.8 - /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.
The OpenVMS operating system uses the default volume extension
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_DEFAULT command.
3.9 - /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 OpenVMS Guide to System Security. 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 an OpenVMS system, but is provided to control
the process's use of the volume on RSX-11M systems. OpenVMS
systems always use the default file protection. Use the
SET PROTECTION/DEFAULT command to change the default file
protection.
3.10 - /GROUP
Used in conjunction with the /NOSHARE qualifier to create
a group volume. The group volume allows access by system
(S), owner (O), and group (G) accessors. The protection is
(S:RWCD,O:RWCD,G:RWCD,W).
The owner user identification code (UIC) of the volume defaults
to your group number and a member number of 0.
3.11 - /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.
NOTE
The default value for the /HEADERS qualifier is generally
insufficient for ODS-2 disks. To improve performance and
avoid SYSTEM-F-HEADERFULL errors, Compaq recommends that
you set this value to be approximately the number of files
that you anticipate having on your disk; however, grossly
overestimating this value will result in wasted disk space.
The /HEADERS qualifier controls how much space is initially
allocated to INDEXF.SYS for headers. Each file on a disk requires
at least one file header and each header occupies one block
within INDEXF.SYS. Files that have many Access Control Entries
(ACE) or are very fragmented may use more than one header.
The default value of 16 leaves room for less than 10 files to be
created before INDEXF.SYS must extend; therefore, try to estimate
the total number of files that will be created on the disk and
specify it here. This will improve disk access performance.
Overestimating the value may lead to wasted disk space. This
value cannot be changed without reinitializing the volume.
INDEXF.SYS is limited as to how many times it may extend. When
the map area in its header (where the retrieval pointers are
stored) becomes full, file creation fails with the message
"SYSTEM-W-HEADERFULL."
3.12 - /HIGHWATER
/HIGHWATER (default)
/NOHIGHWATER
Affects Files-11 On-Disk Structure Level 2 disks only.
Sets the file high-water mark (FHM) volume attribute, which
guarantees that users cannot read data that they have not
written. You cannot specify the /NOHIGHWATER qualifier for
magnetic tape.
The /NOHIGHWATER qualifier disables FHM for a disk volume.
3.13 - /HOMEBLOCKS
/HOMEBLOCKS=option
This qualifier applies only to Files-11 ODS-2 volumes.
It specifies where the volume's homeblock and spare copy of the
homeblock are placed on disk. The value of option can be one of
the following:
o GEOMETRY
Causes the homeblocks to be placed at separate locations on
disk, to protect against failure of a disk block. Placement
depends on the reported geometry of the disk.
o FIXED
Causes the homeblocks to be placed at separate fixed locations
on the disk; this is the default. Placement is independent
of the reported geometry of the disk. This caters for disks
that report different geometries according to which type of
controller they are attached to.
o CONTIGUOUS
Causes the homeblocks to be placed contiguously at the start
of the disk. This allows container file systems to maximize
the amount of contiguous space on the disk, when used with the
/INDEX=BEGINNING qualifier.
3.14 - /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
3.15 - /INTERCHANGE
Specifies that the magnetic tape will be used for interchange in
a heterogeneous vendor environment. The /INTERCHANGE qualifier
omits the ANSI VOL2 labels. Under OpenVMS, the ANSI VOL2 labels
contain OpenVMS specific security attributes.
For more information on the /INTERCHANGE qualifier and on
magnetic tape labeling and tape interchange, refer to the OpenVMS
System Manager's Manual, Volume 1: Essentials.
3.16 - /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 OpenVMS 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 OpenVMS 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
OpenVMS 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 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.
3.17 - /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.
3.18 - /MEDIA_FORMAT
/MEDIA_FORMAT=[NO]COMPACTION
Controls whether data records are automatically compacted and
blocked together on any device that supports 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 noncompaction has been selected
for a given cartridge, that same status applies to the entire
cartridge.
3.19 - /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, OpenVMS provides a routine that
checks this field in the following manner. If the
magnetic tape was created on a version of OpenVMS
that conforms to Version 3 of ANSI, this option
must be used to override any character other than
an ASCII space. If a 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 VAX/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_ Allows you to override the processing of the
IDENTIFIER 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.
You can initialize a volume previously initialized with
/PROTECTION if you have control access.
3.20 - /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 OpenVMS Guide to System Security.
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.
3.21 - /PROTECTION
/PROTECTION=(ownership[:access][,...])
Applies the specified protection to the volume:
o Specify the ownership parameter as system (S), owner (O),
group (G), or world (W).
o Specify the access parameter as read (R), write (W), create
(C), 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 an OpenVMS
specific volume label. The system applies only read (R) and
write (W) access restrictions; create 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, refer to the
OpenVMS Guide to System Security. 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.
3.22 - /SHADOW
/SHADOW=(device_name_1, device_name_2, device_name_3) label
Initializes multiple members of a future shadow set. Initializing
multiple members in this way eliminates the requirement of a full
copy when you later create a shadow set.
The INITIALIZE command with the /SHADOW and /ERASE qualifiers
performs the following operations:
o Formats up to six devices with one command, so that any three
can be subsequently mounted together as members of a new host-
based shadow set
o Writes a label on each volume
o Deletes all information from the devices except for the system
files containing identical file structure information. All
former contents of the disks are lost.
You can then mount up to three of the devices that you have
initialized in this way as members of a new host-based shadow
set.
Compaq strongly recommends that you use the /ERASE qualifier. By
using the /ERASE qualifier, no merge operation is required when
you create the shadow set with the MOUNT command.
All the devices must have identical, nonzero values for Total
Blocks. You can view the Total Blocks value by entering the
SHOW DEVICE/FULL command. If a device has never been mounted
or initialized on this system, the SHOW DEVICE/FULL command for
the device will not display a value for Total Blocks. To correct
this condition, either mount and then dismount the device,
or initialize the device. The Total Blocks value will then be
displayed by SHOW DEVICE/FULL.
Note that the INITIALIZE/SHADOW command should not be used to
initialize a disk to be added to an existing shadow set, as no
benefit is gained.
Additional information can be found in Volume Shadowing for
OpenVMS.
3.23 - /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.
3.24 - /SIZE
/SIZE=n
Specifies the size of the DECram disk (device type DT$_RAM_DISK)
to be allocated from available memory. The size of the device is
created at disk initialization time.
To deallocate space, specify /SIZE=0. All resources specifically
allocated to the DECram disk are returned to the system.
Note that n cannot exceed 524,280 blocks either on a VAX system
or on versions of DECram prior to Version 2.3. DECram Version
2.3 running on an Alpha system supports up to 67,108,864 blocks,
equivalent to 32GB.
3.25 - /STRUCTURE
/STRUCTURE=level
Specifies whether the volume should be formatted in Files-11
On-Disk Structure Level 1, 2 (the default), or 5.
Structure Level 1 is incompatible with the /DATA_CHECK and
/CLUSTER_SIZE qualifiers. The default protection for a Structure
Level 1 disk is full access to system, owner, and group, and read
(R) access to all other users.
Note that Alpha does not support Files-11 On-Disk Structure Level
1 disks, and specifying 1 on Alpha results in an error. VAX does
not support Structure Level 5 disks, and specifying 5 on VAX
results in an error.
Refer to the OpenVMS Guide to Extended File Specifications for
more information about Structure Level 5 (ODS-5) disks.
3.26 - /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.
3.27 - /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.
3.28 - /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.
3.29 - /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.
| 4 - 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:[GOLDSTEIN]
This 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.

This example shows correct use of the INITIALIZE/ERASE/SHADOW
command. Note that the command specifies multiple devices on
the same line.
5 - /QUEUE
Creates or initializes queues. You use this command to create
queues and to assign them names and options. The /BATCH qualifier
is required to create a batch queue.
Requires OPER (operator) privilege to create queues and manage
(M) access to modify queues.
Format
INITIALIZE/QUEUE queue-name[:]
5.1 - Parameter
queue-name[:]
Specifies the name of an execution queue or a generic queue. The
queue name may be a string of 1 to 31 characters. The character
string can include any uppercase and lowercase letters, digits,
the dollar sign ($), and the underscore (_), and must include at
least one alphabetic character.
5.2 - Qualifiers
5. 2.1 - /AUTOSTART_ON
/AUTOSTART_ON=(node::[device][,...])
Designates the queue as an autostart execution queue and
specifies the node, or node and device, on which the queue can
be located. For batch queues, only node is applicable.
In a cluster, you can specify more than one node (or node and
device) on which a queue can run, in the preferred order in which
nodes should claim the queue. This allows the queue to fail over
to another node if the node on which the queue is running leaves
the cluster.
When you enter the INITIALIZE/QUEUE command with the /AUTOSTART_
ON qualifier, you must initially activate the queue for
autostart, either by specifying the /START qualifier with the
INITIALIZE/QUEUE command or by entering a START/QUEUE command.
However, the queue will not begin processing jobs until the
ENABLE AUTOSTART/QUEUES command is entered for a node on which
the queue can run.
This qualifier cannot be used in conjunction with the /ON
or /GENERIC qualifier. However, if you are reinitializing an
existing queue, you can specify the /AUTOSTART_ON qualifier for a
queue previously created or started with the /ON qualifier. Doing
so overrides the /ON qualifier and makes the queue an autostart
queue.
For more information about autostart queues, refer to the chapter
about queues in OpenVMS System Manager's Manual, Volume 1:
Essentials.
5. 2.2 - /BASE_PRIORITY
/BASE_PRIORITY=n
Specifies the base process priority at which jobs are initiated
from a batch execution queue. By default, if you omit the
qualifier, jobs are initiated at the same priority as the base
priority established by DEFPRI at system generation (usually 4).
The base priority specifier can be any decimal value from 0 to
15.
You also can specify this qualifier for an output execution
queue. In this context the /BASE_PRIORITY qualifier establishes
the base priority of the symbiont process when the symbiont
process is created.
5. 2.3 - /BATCH
/BATCH
/NOBATCH (default)
Specifies that you are initializing a batch queue. If you
are reinitializing an existing queue, you can use the /BATCH
qualifier only if the queue was created as a batch queue.
A batch queue is classified as either an execution queue or a
generic queue. By default, the /BATCH qualifier initializes
an execution queue. To specify a generic batch queue, use the
/GENERIC qualifier together with the /BATCH qualifier.
The /BATCH and /DEVICE qualifiers are mutually exclusive; the
/NOBATCH and /NODEVICE qualifiers cannot be used together.
5. 2.4 - /BLOCK_LIMIT
/BLOCK_LIMIT=([lowlim,]uplim)
/NOBLOCK_LIMIT (default)
Limits the size of print jobs that can be processed on an output
execution queue. The /BLOCK_LIMIT qualifier allows you to reserve
certain printers for certain size jobs. You must specify at least
one of the parameters.
The lowlim parameter is a decimal number referring to the minimum
number of blocks accepted by the queue for a print job. If
a print job is submitted that contains fewer blocks than the
lowlim value, the job remains pending until the block limit for
the queue is changed. After the block limit for the queue is
decreased sufficiently, the job is processed.
The uplim parameter is a decimal number referring to the maximum
number of blocks that the queue accepts for a print job. If a
print job is submitted that exceeds this value, the job remains
pending until the block limit for the queue is changed. After the
block limit for the queue is increased sufficiently, the job is
processed.
If you specify only an upper limit for jobs, you can omit the
parentheses. For example, /BLOCK_LIMIT=1000 means that only jobs
with 1000 blocks or less are processed in the queue. To specify
only a lower job limit, you must use a null string ("") to
indicate the upper specifier. For example, /BLOCK_LIMIT=(500,"")
means any job with 500 or more blocks is processed in the queue.
You can specify both a lower and upper limit. For example,
/BLOCK_LIMIT=(200,2000) means that jobs with less than 200 blocks
or more than 2000 blocks are not processed in the queue.
The /NOBLOCK_LIMIT qualifier cancels the previous setting
established by the /BLOCK_LIMIT qualifier for that queue.
5. 2.5 - /CHARACTERISTICS
/CHARACTERISTICS=(characteristic[,...])
/NOCHARACTERISTICS (default)
Specifies one or more characteristics for processing jobs on
an execution queue. If you specify only one characteristic,
you can omit the parentheses. If a queue does not have all the
characteristics that have been specified for a job, the job
remains pending. Each time you specify the /CHARACTERISTICS
qualifier, all previously set characteristics are cancelled. Only
the characteristics specified with the qualifier are established
for the queue.
Queue characteristics are installation specific. The
characteristic parameter can be either a value from 0 to
127 or a characteristic name that has been defined by the
DEFINE/CHARACTERISTIC command.
The /NOCHARACTERISTICS qualifier cancels any settings previously
established by the /CHARACTERISTICS qualifier for that queue.
5. 2.6 - /CLOSE
Prevents jobs from being entered in the queue through PRINT or
SUBMIT commands or as a result of requeue operations. To allow
jobs to be entered, use the /OPEN qualifier. Whether a queue
accepts or rejects new job entries is independent of the queue's
state (such as paused, stopped, or stalled). When a queue is
marked closed, jobs executing continue to execute. Jobs pending
in the queue continue to be candidates for execution.
5. 2.7 - /CPUDEFAULT
/CPUDEFAULT=time
Defines the default CPU time limit for all jobs in this batch
execution queue. You can specify time as delta time, 0, INFINITE,
or NONE (default). You can specify up to 497 days of delta time.
If the queue does not have a specified CPUMAXIMUM time limit and
the value established in the user authorization file (UAF) has
a specified CPU time limit of NONE, either the value 0 or the
keyword INFINITE allows unlimited CPU time. If you specify NONE,
the CPU time value defaults to the value specified either in the
UAF or by the SUBMIT command (if included). CPU time values must
be greater than or equal to the number specified by the system
parameter PQL_MCPULM. The time cannot exceed the CPU time limit
set by the /CPUMAXIMUM qualifier. For information on specifying
delta time, refer to the OpenVMS User's Manual or the online help
topic DCL_Tips (subtopic Date_Time).
5. 2.8 - /CPUMAXIMUM
/CPUMAXIMUM=time
Defines the maximum CPU time limit for all jobs in a batch
execution queue. You can specify time as delta time, 0, INFINITE,
or NONE (default). You can specify up to 497 days of delta time.
The /CPUMAXIMUM qualifier overrides the time limit specified
in the user authorization file (UAF) for any user submitting a
job to the queue. Either the value 0 or the keyword INFINITE
allows unlimited CPU time. If you specify NONE, the CPU time
value defaults to the value specified either in the UAF or by
the SUBMIT command (if included). CPU time values must be greater
than or equal to the number specified by the system parameter
PQL_MCPULM.
For information on specifying delta times, refer to the OpenVMS
User's Manual or the online help topic DCL_Tips (subtopic Date_
Time).
A CPU time limit for processes is specified by each user record
in the system UAF. You also can specify the following: a default
CPU time limit or a maximum CPU time limit for all jobs in a
given queue, or a default CPU time limit for individual jobs in
the queue. The following table shows the action taken for each
value specified and possible combinations of specifications.
Default

and queue's default
values.
5. 2.9 - /DEFAULT
/DEFAULT=(option[,...])
/NODEFAULT
Establishes defaults for certain options of the PRINT command.
Defaults are specified by the list of options. If you specify
only one option, you can omit the parentheses. After you set an
option for the queue with the /DEFAULT qualifier, you do not have
to specify that option in your PRINT command. If you do specify
these options in your PRINT command, the values specified with
the PRINT command override the values established for the queue
with the /DEFAULT qualifier.
You cannot use the /DEFAULT qualifier with the /GENERIC
qualifier.
Possible options are as follows:
[NO]BURST[=keyword] Controls whether two file flag pages
with a burst bar between them are printed
preceding output. If you specify the value
ALL (default), these flag pages are printed
before each file in the job. If you specify
the value ONE, these flag pages are printed
once before the first file in the job.
[NO]FEED Controls whether a form feed is inserted
automatically at the end of a page.
[NO]FLAG[=keyword] Controls whether a file flag page is
printed preceding output. If you specify
the value ALL (default), a file flag page
is printed before each file in the job. If
you specify the value ONE, a file flag page
is printed once before the first file in
the job.
FORM=type Specifies the default form for an output
execution queue. If a job is submitted
without an explicit form definition, this
form is used to process the job. If no
form type is explicitly specified with
the FORM keyword, the system assigns the
form DEFAULT to the queue. See also the
description of the /FORM_MOUNTED=type
qualifier.
[NO]TRAILER[=keyword] Controls whether a file trailer page is
printed following output. If you specify
the value ALL (default), a file trailer
page is printed after each file in the job.
If you specify the value ONE, a trailer
page is printed once after the last file in
the job.
When you specify the BURST option for a file, the [NO]FLAG option
does not add or subtract a flag page from the two flag pages that
are printed preceding the file.
For information on establishing mandatory queue options, see the
description of the /SEPARATE qualifier. For more information on
specifying default queue options, refer to the chapter on queues
in the OpenVMS System Manager's Manual.
5. 2.10 - /DESCRIPTION
/DESCRIPTION=string
/NODESCRIPTION (default)
Specifies a string of up to 255 characters used to provide
operator-supplied information about the queue.
Enclose strings containing lowercase letters, blanks, or other
nonalphanumeric characters (including spaces) in quotation marks
(" ").
The /NODESCRIPTION qualifier removes any descriptive text that
may be associated with the queue.
5. 2.11 - /DEVICE
/DEVICE[=option]
/NODEVICE
Specifies that you are initializing an output queue of a
particular type. If you are reinitializing an existing queue,
you can use the /DEVICE qualifier only if the queue was created
as an output queue. Possible options are as follows:
PRINTER Indicates a printer queue.
SERVER Indicates a server queue. A server queue is
controlled by the user-modified or user-written
symbiont specified with the /PROCESSOR qualifier.
TERMINAL Indicates a terminal queue.
If you specify the /DEVICE qualifier without a queue type, the
/DEVICE=PRINTER qualifier is used by default.
An output queue is classified as either an execution or generic
queue. By default, the /DEVICE qualifier initializes an execution
queue of the designated type. To specify a generic printer,
server, or terminal queue, use the /GENERIC qualifier with the
/DEVICE qualifier.
You specify the queue type with the /DEVICE qualifier for
informational purposes. When an output execution queue is
started, the symbiont associated with the queue determines
the actual queue type. The standard symbiont examines device
characteristics to establish whether the queue should be marked
as printer or terminal. By convention, user-modified and user-
written symbionts mark the queue as a server queue. The device
type of a generic queue need not match the device type of its
execution queues.
The /DEVICE and /BATCH qualifiers are mutually exclusive; the
/NODEVICE and /NOBATCH qualifiers cannot be used together.
5. 2.12 - /DISABLE_SWAPPING
/DISABLE_SWAPPING
/NODISABLE_SWAPPING (default)
Controls whether batch jobs executed from a queue can be swapped
in and out of memory.
5. 2.13 - /ENABLE_GENERIC
/ENABLE_GENERIC (default)
/NOENABLE_GENERIC
Specifies whether files queued to a generic queue that does
not specify explicit queue names with the /GENERIC qualifier
can be placed in this execution queue for processing. For more
information, see the description of the /GENERIC qualifier.
5. 2.14 - /FORM_MOUNTED
/FORM_MOUNTED=type
Specifies the mounted form for an output execution queue.
If no form type is explicitly specified, the system assigns the
form DEFAULT to the queue.
If the stock of the mounted form does not match the stock of the
default form, as indicated by the /DEFAULT=FORM qualifier, all
jobs submitted to this queue without an explicit form definition
enter a pending state and remains pending until the stock of the
mounted form of the queue is identical to the stock of the form
associated with the job.
If a job is submitted with an explicit form and the stock of the
explicit form is not identical to the stock of the mounted form,
the job enters a pending state and remains pending until the
stock of the mounted form of the queue is identical to the stock
of the form associated with the job.
To specify the form type, use either a numeric value or a form
name that has been defined by the DEFINE/FORM command. Form
types are installation-specific. You cannot use the /FORM_MOUNTED
qualifier with the /GENERIC qualifier.
5. 2.15 - /GENERIC
/GENERIC[=(queue-name[,...])]
/NOGENERIC (default)
Specifies a generic queue. Also specifies that jobs placed in
this queue can be moved for processing to compatible execution
queues. The /GENERIC qualifier optionally accepts a list of
target execution queues that have been previously defined. For a
generic batch queue, these target queues must be batch execution
queues. For a generic output queue, these target queues must be
output execution queues, but can be of any type (printer, server,
or terminal). For example, a generic printer queue can feed a
mixture of printer and terminal execution queues.
If you do not specify any target execution queues with the
/GENERIC qualifier, jobs can be moved to any execution queue
that (1) is initialized with the /ENABLE_GENERIC qualifier, and
(2) is the same type (batch or output) as the generic queue.
To define the queue as a generic batch or output queue, you use
the /GENERIC qualifier with either the /BATCH or the /DEVICE
qualifier. If you specify neither /BATCH nor /DEVICE on creation
of a generic queue, the queue becomes a generic printer queue by
default.
You cannot use the /SEPARATE qualifier with the /GENERIC
qualifier.
5. 2.16 - /JOB_LIMIT
/JOB_LIMIT=n
Indicates the number of batch jobs that can be executed
concurrently from the queue. Specify a number in the range 1
to 255. The job limit default value for n is 1.
5. 2.17 - /LIBRARY
/LIBRARY=filename
/NOLIBRARY
Specifies the file name for the device control library. When you
initialize an output execution queue, you can use the /LIBRARY
qualifier to specify an alternate device control library. The
default library is SYS$LIBRARY:SYSDEVCTL.TLB. You can use only a
file name as the parameter of the /LIBRARY qualifier. The system
always assumes that the file is located in SYS$LIBRARY and that
the file type is .TLB.
5. 2.18 - /NAME_OF_MANAGER
/NAME_OF_MANAGER=name
Identifies the name of the queue manager to control the queue.
Once the queue is created, the queue manager assignment may not
be altered.
If the /NAME_OF_MANAGER qualifier is omitted, then the default
name SYS$QUEUE_MANAGER is used.
If the INITIALIZE/QUEUE command is used to modify a queue, and
that queue is not controlled by the default queue manager, then
the name of the controlling queue manager should be specified
with the /NAME_OF_MANAGER qualifier. Alternately, the logical
name SYS$QUEUE_MANAGER can be defined to be the correct queue
manager, making that queue manager the default for the current
process.
5. 2.19 - /NO_INITIAL_FF
/NO_INITIAL_FF
/NONO_INITIAL_FF (default)
Allows user to specify whether a form feed should be sent to a
printer device when a queue starts. To suppress the initial form
feed, use the /NO_INITIAL_FF qualifier.
The /NONO_INITIAL_FF qualifier sends a form feed to the output
device to ensure the paper is at the top of a page before
printing begins.
5. 2.20 - /ON
/ON=[node::]device[:] (printer, terminal, server queue)
/ON=node:: (batch queue)
Specifies the node or device, or both, on which this execution
queue is located. For batch execution queues, you can specify
only the node name. For output execution queues, you can include
both the node name and the device name. By default, a queue
executes on the same node from which you start the queue. The
default device parameter is the same as the queue name.
The node name is used in OpenVMS Cluster systems; it must match
the node name specified by the system parameter SCSNODE for the
OpenVMS computer on which the queue executes.
You cannot use the /ON qualifier with the /AUTOSTART_ON or
/GENERIC qualifier; however, if you are reinitializing an
existing queue, you can specify the /ON qualifier for a queue
previously created or started with the /AUTOSTART_ON qualifier.
Doing so overrides the /AUTOSTART_ON option and makes the queue a
nonautostart queue.
5. 2.21 - /OPEN
/OPEN (default)
Allows jobs to be entered in the queue through PRINT or SUBMIT
commands or as the result of requeue operations. To prevent
jobs from being entered in the queue, use the /CLOSE qualifier.
Whether a queue accepts or rejects new job entries is independent
of the queue's state (such as paused, stopped, or stalled).
5. 2.22 - /OWNER_UIC
/OWNER_UIC=uic
Enables you to change the user identification code (UIC) of the
queue. Specify the UIC by using standard UIC format as described
in the OpenVMS Guide to System Security. The default UIC is
[1,4].
5. 2.23 - /PROCESSOR
/PROCESSOR=filename
/NOPROCESSOR
Allows you to specify your own print symbiont for an output
execution queue. You can use any valid file name as a parameter
of the /PROCESSOR qualifier. The system supplies the device and
directory name SYS$SYSTEM and the file type .EXE. If you use this
qualifier for an output queue, it specifies that the symbiont
image to be executed is SYS$SYSTEM:filename.EXE.
By default, SYS$SYSTEM:PRTSMB.EXE is the symbiont image
associated with an output execution queue.
The /NOPROCESSOR qualifier cancels any previous setting
established with the /PROCESSOR qualifier and causes
SYS$SYSTEM:PRTSMB.EXE to be used.
5. 2.24 - /PROTECTION
/PROTECTION=(ownership[:access],...)
Specifies the protection of the queue:
o Specify the ownership parameter as system (S), owner (O),
group (G), or world (W).
o Specify the access parameter as read (R), submit (S), manage
(M), or delete (D).
A null access specification means no access. The default
protection is (SYSTEM:M, OWNER:D, GROUP:R, WORLD:S). If you
include only one protection code, you can omit the parentheses.
For more information on specifying protection codes, refer to
the OpenVMS Guide to System Security. For more information on
controlling queue operations through UIC-based protection, refer
to the chapter on queues in the OpenVMS System Manager's Manual.
5. 2.25 - /RECORD_BLOCKING
/RECORD_BLOCKING (default)
/NORECORD_BLOCKING
Determines whether the symbiont can concatenate (or block
together) output records for transmission to the output device.
If you specify the /NORECORD_BLOCKING qualifier, the symbiont
sends each formatted record in a separate I/O request to the
output device. For the standard OpenVMS print symbiont, record
blocking can have a significant performance advantage over
single-record mode.
5. 2.26 - /RETAIN
/RETAIN[=option]
/NORETAIN (default)
Holds jobs in the queue in a retained state after they have
executed. The /NORETAIN qualifier enables you to reset the queue
to the default. Possible options are as follows:
ALL Holds all jobs in the queue after execution.
(default)
ERROR Holds in the queue only jobs that complete
unsuccessfully.
A user can request a job retention option for a job by specifying
the /RETAIN qualifier with the PRINT, SUBMIT, or SET ENTRY
command; however, the job retention option you specify for a
queue overrides any job retention option requested by a user for
a job in that queue.
5. 2.27 - /SCHEDULE
/SCHEDULE=SIZE (default)
/SCHEDULE=NOSIZE
Specifies whether pending jobs in an output execution queue are
scheduled for printing based on the size of the job. When the
default qualifier /SCHEDULE=SIZE is in effect, shorter jobs print
before longer ones.
When the /SCHEDULE=NOSIZE qualifier is in effect, jobs are not
scheduled according to size.
If you enter this command while there are pending jobs in any
queue, its effect on future jobs is unpredictable.
5. 2.28 - /SEPARATE
/SEPARATE=(option[,...])
/NOSEPARATE (default)
Specifies the mandatory queue options, or job separation options,
for an output execution queue. Job separation options cannot be
overridden by the PRINT command.
You cannot use the /SEPARATE qualifier with the /GENERIC
qualifier.
The job separation options are as follows:
[NO]BURST Specifies whether two job flag pages with
a burst bar between them are printed at
the beginning of each job.
[NO]FLAG Specifies whether a job flag page is
printed at the beginning of each job.
[NO]TRAILER Specifies whether a job trailer page is
printed at the end of each job.
[NO]RESET=(module[,...]Specifies one or more device control
library modules that contain the job reset
sequence for the queue. The specified
modules from the queue's device control
library (by default SYS$LIBRARY:SYSDEVCTL)
are used to reset the device at the end
of each job. The RESET sequence occurs
after any file trailer and before any job
trailer. Thus, all job separation pages
are printed when the device is in its
RESET state.
When you specify the /SEPARATE=BURST qualifier, the [NO]FLAG
separation option does not add or subtract a flag page from the
two flag pages that are printed preceding the job.
For information on establishing queue options that can be
overridden, see the description of the /DEFAULT qualifier.
For more information on specifying mandatory queue options, refer
to the chapter on queues in the OpenVMS System Manager's Manual.
5. 2.29 - /START
/START
/NOSTART (default)
Starts the queue being initialized by the current
INITIALIZE/QUEUE command.
For autostart queues, this qualifier activates the queue for
autostart. The queue begins processing jobs when autostart is
enabled with the ENABLE AUTOSTART/QUEUES command on any node on
which the queue can run.
5. 2.30 - /WSDEFAULT
/WSDEFAULT=n
Defines for a batch job a working set default, the default number
of physical pages that the job can use.
The value set by this qualifier overrides the value defined in
the user authorization file (UAF) of any user submitting a job to
the queue.
Specify the value of n as a number of 512-byte pagelets on Alpha
systems or 512-byte pages on VAX. Note that OpenVMS rounds
this value up to the nearest CPU-specific page so that the
actual amount of physical memory allowed may be larger than the
specified amount on Alpha. For further information, refer to the
OpenVMS System Manager's Manual.
If you specify 0 or NONE, the working set default value defaults
to the value specified in the UAF or by the SUBMIT command (if it
includes a WSDEFAULT value).
You also can specify this qualifier for an output execution
queue. Used in this context, the /WSDEFAULT qualifier establishes
the working set default of the symbiont process for an output
execution queue when the symbiont process is created.
5. 2.31 - /WSEXTENT
/WSEXTENT=n
Defines for the batch job a working set extent, the maximum
amount of physical memory that the job can use. The job only
uses the maximum amount of physical memory when the system has
excess free pages. The value set by this qualifier overrides the
value defined in the user authorization file (UAF) of any user
submitting a job to the queue.
Specify the value of n as a number of 512-byte pagelets on Alpha
or and 512-byte pages on VAX. Note that OpenVMS rounds this value
up to the nearest CPU-specific page so that the actual amount of
physical memory allowed may be larger than the specified amount
on Alpha.
If you specify 0 or NONE, the working set extent value defaults
to the value specified in the UAF or by the SUBMIT command (if it
includes a WSEXTENT value).
You also can specify this qualifier for an output execution
queue. Used in this context, the /WSEXTENT qualifier establishes
the working set extent of the symbiont process for an output
execution queue when the symbiont process is created.
5. 2.32 - /WSQUOTA
/WSQUOTA=n
Defines for a batch job a working set quota, the amount of
physical memory that is guaranteed to the job.
The value set by this qualifier overrides the value defined in
the user authorization file (UAF) of any user submitting a job to
the queue.
Specify the value of n as a number of 512-byte pagelets on
OpenVMS Alpha or 512-byte pages on OpenVMS VAX. OpenVMS rounds
this value up to the nearest CPU-specific page so that the
actual amount of physical memory allowed may be larger than the
specified amount on OpenVMS Alpha. For further information, refer
to the OpenVMS System Manager's Manual.
If you specify 0 or NONE, the working set quota value defaults
to the value specified in the UAF or by the SUBMIT command (if it
includes a WSQUOTA value).
You also can specify this qualifier for an output execution
queue. Used in this context, the /WSQUOTA qualifier establishes
the working set quota of the symbiont process for an output
execution queue when the symbiont process is created.
Working set default, working set quota, and working set extent
values are included in each user record in the system UAF. You
can specify working set values for individual jobs or for all
jobs in a given queue. The decision table shows the action taken
for different combinations of specifications that involve working
set values.
Is the SUBMIT Is the
command value queue value
specified? specified? Action taken
No No Use the UAF value.
No Yes Use value for the queue.
Yes Yes Use smaller of the two values.
Yes No Compare specified value with UAF
value; use the smaller.
5.3 - Examples
1.$ INITIALIZE/QUEUE/BATCH/START -
_$ /AUTOSTART_ON=(DATA::, WARF::, DEANNA::) BATCH_1
The INITIALIZE/QUEUE command in this example creates the
batch queue BATCH_1, and designates it as an autostart queue
capable of executing on node DATA, WARF, or DEANNA. The /START
qualifier activates the queue for autostart. The queue will
begin executing on the first node (in the list of nodes
specified) for which the ENABLE AUTOSTART/QUEUES command is
entered.
If the node on which BATCH_1 is executing is taken out of the
OpenVMS Cluster, the queue will be stopped on that node and
will fail over to the first available node in the node list
on which autostart is enabled for a queue manager SYS$QUEUE_
MANAGER.
As long as autostart is enabled on one of the nodes in the
list, this queue will be started and available to execute batch
jobs. If all three nodes in the example are shut down or if
autostart is disabled, the queue will remain stopped until
one of the three nodes in the node list joins the cluster and
executes the ENABLE AUTOSTART/QUEUES command.
The ENABLE AUTOSTART/QUEUES and INITIALIZE/QUEUE commands
affect only the queues managed by the default queue manager
SYS$QUEUE_MANAGER because the /NAME_OF_MANAGER qualifier is not
specified.
2.$ INITIALIZE/QUEUE/START/BATCH/JOB_LIMIT=3 SYS$BATCH
$ INITIALIZE/QUEUE/START/BATCH/JOB_LIMIT=1/WSEXTENT=2000 BIG_BATCH
In this example, the first INITIALIZE/QUEUE command creates
a batch queue called SYS$BATCH that can be used for any batch
job. The /JOB_LIMIT qualifier allows three jobs to execute
concurrently. The second INITIALIZE/QUEUE command creates
a second batch queue called BIG_BATCH that is designed for
large jobs. Only one job can execute at a time. The working
set extent can be as high as 125 pages on OpenVMS Alpha (on a
system with 8KB pages) or 2000 pages on OpenVMS VAX.
3.$ INITIALIZE/QUEUE/START/DEFAULT=(FLAG,TRAILER=ONE)-
_$ /ON=LPA0: LPA0_PRINT
$ INITIALIZE/QUEUE/START/DEFAULT=(FLAG,TRAILER=ONE)-
_$ /BLOCK_LIMIT=(1000,"")/ON=LPB0: LPB0_PRINT
$ INITIALIZE/QUEUE/START/GENERIC=(LPA0_PRINT,LPB0_PRINT) SYS$PRINT
$ INITIALIZE/QUEUE/START/FORM_MOUNTED=LETTER-
_$ /BLOCK_LIMIT=50/ON=TXA5: LQP
In this example, the first three INITIALIZE/QUEUE commands set
up printer queues. Both queue LPA0_PRINT and LPB0_PRINT are
set up to put a flag page before each file within a job and a
trailer page after only the last page in a job. In addition,
LPB0_PRINT has a minimum block size of 1000; therefore, only
print jobs larger than 1000 blocks can execute on that queue.
SYS$PRINT is established as a generic queue that can direct
jobs to either LPA0_PRINT or LPB0_PRINT. Jobs that are too
small to run on LPB0_PRINT will be queued from SYS$PRINT to
LPA0_PRINT.
The last INITIALIZE/QUEUE command sets up a terminal queue on
TXA5. A job queued with a form that has a stock type other
than the stock type of form LETTER remains pending in the
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.
