OpenVMS DCL Dictionary

For more information on types of queues, see the INITIALIZE/QUEUE command. For more information on setting retention options for queues, see the INITIALIZE/QUEUE, START/QUEUE, or SET QUEUE command.

Timed Retention

Timed retention, which you specify using the UNTIL=time-value option, allows you to retain a job in the queue only as long as you need it. This eliminates the need to delete the job from the queue later.

For example, the following command retains job 172 in the queue until 7:31 on April 19, when the job will automatically be deleted from the queue.

$ SET ENTRY/RETAIN=UNTIL=14-DEC-1994:07:31:0.0 172

However, depending on the queue's job retention policy, the job might be retained indefinitely. The job retention policy set on the queue takes precedence over the user-specified job retention setting. Because system managers cannot specify timed job retention for a queue, any jobs retained as a result of a queue's setting are retained indefinitely.

If you specify the /RETAIN=UNTIL=time-value option, you must supply a time value. The time value is first interpreted as a delta time, then as a combination time, and finally as absolute time. If you specify a delta time, the delta begins when the job completes. For example, if you specify SET ENTRY/RETAIN=UNTIL="+3:00", the job will be retained for three hours after the job completes. For information on specifying time values, see the OpenVMS User's Manual.

/SETUP=module[,...]

Extracts the specified modules from the device control library (containing escape sequence modules for programmable printers) and copies the modules to the printer before each file in a print job is printed.

When you use the /SETUP qualifier with the SET ENTRY command, the qualifier applies to the entire print job. You cannot use this qualifier to specify different setup modules for individual files within a multifile job.

/SPACE

/NOSPACE

Controls whether the output of a print job is double-spaced. Specifying the /NOSPACE qualifier causes the output to be single-spaced. When you use the /SPACE qualifier with the SET ENTRY command, the qualifier applies to the entire job. You cannot use this qualifier to specify different spacing for individual files within a multifile job.

/TRAILER

/NOTRAILER

Controls whether a trailer page is printed at the end of each file in a print job. The trailer page displays the entry number, as well as information about the user submitting the job and the files being printed.

When you use the /TRAILER qualifier with the SET ENTRY command, trailer pages are placed at the end of each file in a multifile job.

Use the /[NO]TRAILER qualifier to override the installation-defined defaults that have been set for the output queue you are using or the qualifier specified in the PRINT command that queued the job.

/WSDEFAULT=n

Defines, for a batch job, a working set default, which is the default number of physical pages that the job can use.

If the queue on which the job executes has a nonzero default working set, the smaller of the specified job and queue values is used. If the queue on which the job executes has a working set default of zero, the smaller of the specified job value and the value established in the user authorization file (UAF) is used.

Specify the value of n as a number of 512-byte pagelets on Alpha or 512-byte pages on VAX. Note that the operating system rounds up this value to the nearest CPU-specific page so that actual amount of physical memory allowed may be larger than the specified amount on Alpha. If you specify zero or NONE, the specified queue or UAF value is used. Working set default values must range between the numbers specified by the system parameters PQL_MWSDEFAULT and WSMAX.

/WSEXTENT=n

Defines, for the batch job, a working set extent, which is the maximum amount of physical memory that the job can use. The job uses the maximum amount of physical memory only when the system has excess free pages. If the queue on which the job executes has a nonzero working set extent, the smaller of the specified job and queue values is used. If the queue on which the job executes has a working set extent of zero, the smaller of the specified job value and the value established in the user authorization file (UAF) is used.

Specify the value of n as a number of 512-byte pagelets on Alpha or 512-byte pages on VAX. Note that the operating system rounds up this value to the nearest CPU-specific page so that actual amount of physical memory allowed may be larger than the specified amount on Alpha. If you specify zero or NONE, the specified queue or UAF value is used. Working set extent values must range between the numbers specified by the system parameters PQL_MWSEXTENT and WSMAX.

/WSQUOTA=n

Defines, for the batch job, a working set quota, which is the amount of physical memory that the job is guaranteed. If the queue on which the job executes has a nonzero working set quota, the smaller of the specified job and queue values is used. If the queue on which the job executes has a working set quota of zero, the smaller of the specified job value or the value established in the user authorization file (UAF) is used.

Specify the value of n as a number of 512-byte pagelets on Alpha or 512-byte pages on VAX. Note that the operating system rounds up this value to the nearest CPU-specific page so that actual amount of physical memory allowed may be larger than the specified amount on Alpha. If you specify zero or NONE, the specified queue or UAF value is used. Working set quota values must range between the numbers specified by the system parameters PQL_MWSQUOTA and WSMAX.

Examples

$ PRINT/HOLD   MYFILE.DAT
  Job MYFILE (queue SYS$PRINT, entry 112) holding
$ SET ENTRY 112/RELEASE/JOB_COUNT=3

The PRINT command in this example requests that the file MYFILE.DAT be queued to the system printer, but placed in a hold status. The SET ENTRY command releases the job for printing and requests that three copies of the job be printed.

$ SUBMIT CLIMATE
  Job CLIMATE (queue SYS$BATCH, entry 211) pending
$ SET ENTRY 211/HOLD/NAME=TEMP

The SUBMIT command in this example queues the command procedure CLIMATE.COM for processing as a batch job. The SET ENTRY command places the job in a hold state and changes the job name to TEMP, assuming that the job has not yet begun execution.

$ PRINT/FLAG=ALL/AFTER=20:00 MEMO.MEM, LETTER.MEM, REPORT.MEM/SPACE
  Job MEMO (queue SYS$PRINT, entry 172) holding until 20:00
$ SET ENTRY 172 /BURST/NOSPACE/HEADER

The PRINT command in this example requests that three files be printed after 8:00 P.M. on the default printer with flag pages preceding each file. It also requests that the file REPORT.MEM be double-spaced. Later a SET ENTRY command calls for a burst page at the beginning of each file and requests that all files in the job be single-spaced. This command also requests that headers be printed on each page of each file in the job.

SET FILE

Modifies the characteristics of one or more files.
See the qualifier descriptions for restrictions.

Format

SET FILE filespec[,...]

PARAMETER

filespec[,...]
Specifies one or more files to be modified. If you specify more than one file, separate the file specifications with commas (,). The asterisk (*) and the percent sign (%) wildcard characters are allowed.

DESCRIPTION

The SET FILE command modifies a number of file characteristics.

/BACKUP

/NOBACKUP
Specifies that the Backup utility (BACKUP) records the contents of the file. The /NOBACKUP qualifier causes BACKUP to record the attributes of the file but not its contents. This qualifier is valid only for Files-11 Structure On-Disk Level 2 files.
The /NOBACKUP qualifier is useful for saving files that contain unimportant data, such as SWAPFILES.
/BEFORE[=time]
Selects only those files dated prior to the specified time. You can specify time as absolute time, as a combination of absolute and delta times, or as one of the following keywords: BOOT, LOGIN, TODAY (default), TOMORROW, or YESTERDAY. Specify the /CREATED or the /MODIFIED qualifier to indicate the time attribute to be used as the basis for selection. The /CREATED qualifier is the default.
For complete information on specifying time values, see the OpenVMS User's Manual or the topic SPECIFY Date_Time in online help.
/BY_OWNER[=uic]
Selects only those files whose owner user identification code (UIC) matches the specified owner UIC. The default UIC is that of the current process.
Specify the UIC by using standard UIC format as described in the OpenVMS Guide to System Security.

/CACHING=option (Alpha only)
On Alpha systems, this qualifier sets the caching attribute of files and directories stored in Spiralog volumes, whose device type is Files_64. It returns an error if any of the specified files and directories are not in Spiralog volumes.
The caching attribute of a file specifies the default caching option for the file. This is the caching option that is used whenever an application accesses the file without specifying which caching option it wants to use.
The value of option can be one of the following:

WRITEBEHIND
Selects write-behind caching without flush on close.
Write-behind caching improves the performance of write operations. It allows Spiralog to buffer writes to the file in your computer's cache and to reduce the number of I/Os to disk by amalgamating writes. This improves both application response time and overall data throughput.
When an application writes to the file, Spiralog writes the data to its cache. The application proceeds as soon as the data is in the cache. Some time within the next 30 seconds, Spiralog writes the data to disk.
FLUSH_ON_CLOSE
Selects write-behind caching with flush on close.
This is identical to the WRITEBEHIND option except that the file's data is written to disk when the application closes the file. If the file has any data in your computer's Spiralog cache that has not yet been written to disk, Spiralog writes the data to disk before it closes the file.
WRITETHROUGH
Selects write-through caching.
Write-through caching writes data straight through to disk. When an application writes to the file, Spiralog writes the data straight through to disk before putting it in the cache. The application cannot proceed until the data is on disk.

The caching attribute of a directory controls how the caching attribute is inherited by new files created in it.
When you create a new directory or file, it inherits its caching attribute from its parent directory. When you create a new version of an existing file, the new file inherits its caching attribute from the highest version of the existing file.
When you change the caching attribute of a directory, it does not affect the caching attribute of any existing files and subdirectories in the directory.
When you change the caching attribute of a file, it does not affect the caching option being used by applications that are currently accessing the file. It affects only subsequent accesses to the file.

/CONFIRM

/NOCONFIRM (default)
Controls whether a request is issued before each SET FILE operation to confirm that the operation should be performed on that file. The following responses are valid:

YES NO QUIT

TRUE FALSE Ctrl/Z

1 0 ALL

[Return]

You can use any combination of uppercase and lowercase letters for word responses. Word responses can be abbreviated to one or more letters (for example, T, TR, or TRU for TRUE), but these abbreviations must be unique. Affirmative answers are YES, TRUE, and 1. Negative answers include: NO, FALSE, 0, and pressing the Return key. Entering QUIT or pressing Ctrl/Z indicates that you want to stop processing the command at that point. When you respond by entering ALL, the command continues to process, but no further prompts are given. If you type a response other than one of those in the list, DCL issues an error message and redisplays the prompt.
/CREATED (default)
Modifies the time value specified with the /BEFORE or the /SINCE qualifier. The /CREATED qualifier selects files based on their dates of creation. This qualifier is incompatible with the /MODIFIED qualifier, which also allows you to select files according to time attributes. The /CREATED qualifier is the default qualifier.
/DATA_CHECK[=([NO]READ,[NO]WRITE)]
Specifies whether a read data check (rereading each record), a write data check (reading each record after it is written), or a combination of the two is performed on the file during transfers. By default, a write data check is performed.
/END_OF_FILE
Resets the end-of-file (EOF) mark to the highest block allocated.
/ENTER=alias-filespec
Use with caution.
Creates an alias for the specified file. Both the original name and the new alias refer to the same file. To remove the alias, use the SET FILE /REMOVE command.

Note
Make sure that the alias and the original name are in different directories, or you may subsequently lose data during a delete or purge operation. The DELETE and PURGE commands and the file version limit feature can behave unpredictably if the original name and the alias are in the same directory.
If you use aliases you must also be careful when you use the DELETE and SET FILE /REMOVE commands, or you may end up with either an inaccessable file that has no name or a name that does not refer to a file. Follow these guidelines to avoid these problems:

Use SET FILE /REMOVE to remove an alias; do not use the DELETE command to remove an alias.
Do not use SET FILE /REMOVE to remove the original file name.

If you do not follow these guidelines and encounter problems, use ANALYZE /DISK /REPAIR to move inaccessable files to the SYSLOST directory and remove names that no longer refer to files.

/ERASE_ON_DELETE
Specifies that the specified files are erased from the disk (not just written over) when the DELETE or PURGE command is issued for the files. See the DELETE/ERASE command for more information.
/EXCLUDE=(filespec[,...])
Excludes the specified file from the SET FILE operation. You can include a directory name but not a device name in the file specifications. The asterisk (*) and the percent sign (%) wildcard characters are allowed in the file specification. However, you cannot use relative version numbers to exclude a specific version. If you specify only one file, you can omit the parentheses.
/EXPIRATION_DATE=date

/NOEXPIRATION_DATE
Requires read (R), write (W), and control access. Being the owner of the file is one way to get control access.
Controls whether an expiration date is assigned to the specified files.
Specify the date according to the rules described in the OpenVMS User's Manual or the topic SPECIFY Date_Time in online help. Absolute date keywords are allowed. If you specify zero as the date, today's date is used.
/EXTENSION[=n]
Sets the extend quantity default for the file. The value of the parameter n can range from 0 to 65,535. If you omit the value specification or specify a value of 0, OpenVMS Record Management Services (OpenVMS RMS) calculates its own value for the /EXTENSION qualifier.
See the SET RMS_DEFAULT command for a description of the /EXTEND_QUANTITY qualifier.
/GLOBAL_BUFFER=n
Sets the OpenVMS Record Management Services (OpenVMS RMS) global buffer count (the number of buffers that can be shared by processes accessing the file) for the specified files. The value n must be an integer in the range from 0 to 32,767. A value of 0 disables buffer sharing.
/LOG

/NOLOG (default)
Displays the file specification of each file modified as the command executes.
/MODIFIED
Modifies the time value specified with the /BEFORE or the /SINCE qualifier. The /MODIFIED qualifier selects files according to the dates on which they were last modified. This qualifier is incompatible with the /CREATED qualifier, which also allows you to select files according to time attributes. If you do not specify the /MODIFIED qualifier, the default is the /CREATED qualifier.
/MOVE

/NOMOVE
Controls whether movefile operations are enabled on the specified file.
When you create a file, movefile operations are enabled on that file. You should disable movefile operations on specialized files that are accessed other than through the XQP (such as files accessed through logical I/O to a disk).
Note that movefile operations are automatically disabled on critical system files. Do not enable movefile operations on these files.
/NODIRECTORY
Use with extreme caution. Requires SYSPRV (system privilege).
Removes the directory attributes of a file and allows you to delete the corrupted directory file even if other files are contained in the directory. When you delete a corrupted directory file, the files contained within it are lost.
Use ANALYZE/DISK_STRUCTURE/REPAIR to place the lost files in [SYSLOST]. You can then copy the lost files to a new directory. This qualifier is valid only for Files-11 On-Disk Structure Level 2 files. For more information about the Verify utility, see the OpenVMS System Management Utilities Reference Manual.
/OWNER_UIC[=uic]
Requires GRPPRV (group privilege) to set the owner to another member of the same group. Requires SYSPRV (system privilege) to set the owner to any user identification code (UIC) outside your group.
Specifies an owner UIC for the file. The default is the UIC of your process.
Specify the UIC by using standard UIC format as described in the OpenVMS Guide to System Security.
/PROTECTION[=(ownership[:access][,...])]
Cannot be used to change the protection on a file via DECnet software.
Enables you to change or reset the protection for one or more of your files.

Specify the ownership parameter as system (S), owner (O), group (G), or world (W).
Specify the access parameter as read (R), write (W), execute (E), or delete (D).

If you specify the /PROTECTION qualifier without an ownership and access code, the file protection is set according to the current default protection.
For more information on specifying protection codes, see the OpenVMS Guide to System Security.
/REMOVE
Use with caution.
Enables you to remove one of the names of a file that has more than one name, without deleting the file. If you have created an additional name for a file with the /ENTER qualifier of SET FILE, you can use the /REMOVE qualifier to remove either the original name or the alias. The file still exists and can be accessed by whatever name or names remain in effect.
However, if you accidentally remove the name of a file that has only one name, you cannot access that file with most DCL commands; use the ANALYZE/DISK_STRUCTURE utility to retrieve the file.
/SEMANTICS=semantics-tag

/NOSEMANTICS
Use the /SEMANTICS qualifier to create or change a semantics tag. Use the /NOSEMANTICS qualifier to remove a semantics tag from a file. For more information, see the Guide to OpenVMS File Applications.
/SHELVABLE

/NOSHELVABLE
Controls whether the file is shelvable.
/SINCE[=time]
Selects only those files dated after the specified time. You can specify time as absolute time, as a combination of absolute and delta times, or as one of the following keywords: BOOT, LOGIN, TODAY (default), TOMORROW, or YESTERDAY. Specify the /CREATED or the /MODIFIED qualifier to indicate the time attribute to be used as the basis for selection. The /CREATED qualifier is the default.
For complete information on specifying time values, see the OpenVMS User's Manual or the topic SPECIFY Date_Time in online help.
/STATISTICS

/NOSTATISTICS (default)
Enables the gathering of RMS statistics on the specified file. These statistics can then be viewed by using the Monitor utility, which is invoked with the DCL command MONITOR. The SET FILE/STATISTICS command applies an application ACE to the specified file. The ACE does not affect access control and is only meaningful to the application assigning it.
/TRUNCATE
Truncates the file at the end of the block containing the end-of-file (EOF) marker, that is, the qualifier releases allocated but unused blocks of the file.
/UNLOCK
Makes one or more improperly closed files accessible.
/VERSION_LIMIT[=n]
Specifies the maximum number of versions for the specified file. If you do not specify a version limit, a value of 0 is used, indicating that the number of versions of a file is limited only to the Files-11 architectural limit of 32,767. When you exceed that limit, the earliest version of the file is deleted from the directory without notification to the user. For example, if you set the version limit to three when there are already five versions of that file in your directory, there will continue to be five versions of the file unless you specifically delete some or purge the directory. Once the number of versions is equal to or less than the current version limit, the version limit is maintained.

Examples

$ SET FILE/EXPIRATION_DATE=19-APR-1995:11:00 BATCH.COM;3

The SET FILE command requests that the expiration date of the file BATCH.COM;3 be set to 11:00 A.M., April 19, 1995.

$ SET FILE/BEFORE=31-DEC/ERASE_ON_DELETE PERSONNEL*.SAL

This SET FILE command calls for all files that match the file specification PERSONNEL*.SAL and are dated before December 31 of the current year to have their disk locations erased whenever one of them is deleted with commands such as DELETE or PURGE.

$ SET FILE/OWNER_UIC=[360,020]/VERSION_LIMIT=100 MYFILE.DAT

The SET FILE command modifies the characteristics of the file MYFILE.DAT, changing the owner user identification code (*). You must have system privilege (SYSPRV) to change the owner UIC.

$ SET FILE/NOMOVE TEST.FDL
$DIRECTORY/FULL TEST.FDL
Directory SYS$SYSDEVICE:[SMITH]
TEST.FDL;1   File ID:  (10,8,0) 
   .
   .
   .
File attributes: Allocation: s, Extend: 0, Global buffer count: 0
   No version limit, MoveFile disabled
   .
   .
   .

Movefile operations are disabled on the file TEST.FDL. A DIRECTORY/FULL command on the file TEST.FDL affirms that the file attribute Movefile is disabled.

$  SET FILE/ATTRIBUTES=ORG:SEQ -
_$ TEST$:[DATA]SET_ATTRIBUTES.DATA_FILE/LOG
%SET-I-MODIFIED, TEST$:[DATA]SET_ATTRIBUTES.DATA_FILE;1 MODIFIED

The command, SET FILE/ATTRIBUTES, changes the file organization of the specified file.

$  SET FILE/PROTECTION=(S:RWE,O=RWE,G:RE,W:RE) TEMP.DIR
$ DIRECTORY/PROTECTION TEMP.DIR
Directory DKB0:[SMITH]
TEMP.DIR;1           (RWE,RWE,RE,RE)

This example sets the protection on the TEMP.DIR file with the SET FILE command and then displays the protection of the file with the DIRECTORY command.

SET HOST

Connects your terminal (through the current host processor) to another processor, called the remote processor. The command requires that:

Both processors must be running DECnet software.¹
You must have an account on the remote system to log in.
The NETMBX (network mailbox) privilege is set.

Format

SET HOST node-name

PARAMETER

node-name
Specifies the node name of the remote processor to which you will connect.

DESCRIPTION

The SET HOST command connects you to another processor on a network. (The SHOW NETWORK command lists the names of nodes accessible to your node.) Once the connection is made, the remote processor prompts for a user name and password. You must have an account on the remote processor to log in.
