STOP/QUEUES/ON_NODE
Stops all queues on the specified node. This command is useful if you want to stop a set of queues on a node with a single command (for example, before shutting down a node), but do not want to stop a queue manager throughout an OpenVMS Cluster. FormatSTOP/QUEUES/ON_NODE[=node] ParametersNone. DescriptionThe STOP/QUEUES/ON_NODE command notifies the queue manager to perform the following tasks: Qualifier

$ STOP/QUEUES/ON_NODE
|
The STOP/QUEUES/ON_NODE command in this example stops all queues on the node from which it is entered. The autostart feature is disabled on this node for all autostart queues.
However, the queue manager process continues to run and schedules jobs as requested for execution on its unstopped queues on other nodes in the OpenVMS Cluster.
This command only affects queues managed by the default queue manager SYS$QUEUE_MANAGER because the /NAME_OF_MANAGER qualifier is not specified.

The INITIALIZE/QUEUE command in this example creates the autostart queue BATCH_1 capable of running on node JADE, RUBY, or OPAL. The /START qualifier activates the queue for autostart. The first ENABLE AUTOSTART/QUEUES command enables autostart of all autostart queues on node JADE, causing the queue BATCH_1 to begin processing on that node. The second ENABLE AUTOSTART/QUEUES command enables autostart for all autostart queues on node RUBY.
Later, suppose node JADE needs to be removed from the cluster. The STOP/QUEUES/ON_NODE command in the example stops all queues on node JADE without stopping the clusterwide queue manager, and causes the autostart queue BATCH_1 to failover to node RUBY, the next available node in its failover list. Because the STOP QUEUES/ON_NODE command disables autostart, the ENABLE AUTOSTART/QUEUES command must be executed on node JADE when it reboots for autostart queues to run on that node in the future.
This command only affects queues managed by the default queue manager SYS$QUEUE_MANAGER because the /NAME_OF_MANAGER qualifier is not specified.
Removes a zone from a running VAXft system. For more information on the STOP/ZONE command, refer to the VAXft systems documentation.Applies only to the VAXft system. Requires CMKRNL (change mode to kernel) privilege.
STOP/ZONE zone-id
Queues one or more files containing command procedures to a batch queue.Requires submit (S) access to the queue.
SUBMIT filespec[,...]
filespec[,...]
Specifies one or more files containing command procedures. The asterisk (*) and the percent sign (%) wildcard characters are allowed in the directory specification, file name, file type, and version number fields. The default file type is that of the preceding file. If no previous file specification contains an explicit file type, the default file type is .COM.If you specify more than one file, separate the file specifications with either commas (,) or plus signs (+).
If you specify a node name, you must use the /REMOTE qualifier.
The SUBMIT command places the specified files in a batch queue for subsequent execution. By default, this queue is SYS$BATCH. All files queued by a single SUBMIT command are processed serially as one job. By default, the name of the batch job is the name of the first file specified in the SUBMIT command.The system assigns a unique entry number to each batch job in the queue. When you enter the SUBMIT command, by default, the system displays the job name, the queue name, the entry number, and the job status.
The system automatically creates or updates the local symbol $ENTRY when a SUBMIT command completes successfully. The value of $ENTRY is a string that identifies the entry number of the most recently queued job. If you want to refer to a job's entry number later, store the value of $ENTRY in another symbol.
After you queue a batch job, the version of the file submitted is processed, even if a newer version of the file is created before the batch job runs. Also, another file with the same name and version number as the file queued cannot be substituted for the file that was submitted.
When the system executes a command procedure submitted to a batch queue, it creates a detached process to execute the commands. This process receives the owner's disk and directory defaults and the same resource quotas and privileges that were given to the owner's interactive process when you logged in.
If multiple procedures are submitted, the job terminates as soon as any procedure exits with an error or severe (fatal) error status.
In an OpenVMS Cluster environment, you should periodically keep the cluster in time synchronization using the SET TIME/CLUSTER command because the differences in system times between nodes in an OpenVMS Cluster may vary. This variance may cause a job to begin executing a little before or after the specified time because the redundancy built into the batch and print system allows more than one job controller in the cluster to receive a timer asynchronous system trap (AST) for the job and, thus, to schedule it for execution.
By default, all output from each command procedure in a batch job is written to a log file. This log file is queued for printing on SYS$PRINT when the batch job finishes. By default, this log file is deleted after it is printed. When you stop a batch job by using the STOP/QUEUE/ENTRY, the STOP/IDENTIFICATION, or the DELETE/ENTRY command, the log file is not queued for printing.
For information on how to change the system's handling of the log file, see the descriptions of the /LOG_FILE, /PRINTER, and /KEEP qualifiers.
/AFTER=time
/NOAFTER
Requests that the job be held until after a specific time. If the specified time has passed already, the job is processed immediately.You can specify time as either absolute time or as a combination of absolute and delta times. For complete information on specifying time values, refer to the OpenVMS User's Manual or the online help topic DCL_Tips (subtopic Date_Time).
In an OpenVMS Cluster, a batch job submitted to execute at a specific time may begin execution a little before or after the requested time. This occurs when the clocks of the member systems in the OpenVMS Cluster are not synchronized. For example, a job submitted using the DCL command SUBMIT/AFTER=TOMORROW may execute at 11:58 P.M. relative to the host system's clock.
This problem can occur in a cluster even if a job is run on the same machine from which it was submitted, because the redundancy built into the batch/print system allows more than one job controller in the cluster to receive a timer asynchronous system trap (AST) for the job and, thus, to schedule it for execution. Moreover, this behavior is exacerbated if the batch job immediately resubmits itself to run the next day using the same SUBMIT command. This can result in having multiple instances of the job executing simultaneously because TOMORROW (after midnight) might be only a minute or two in the future.
A solution to this problem is to place the SUBMIT command in a command procedure that begins with a WAIT command, where the delta-time specified in the WAIT command is greater than the maximum difference in time between any two systems in the cluster. Use the SHOW TIME command on each system to determine this difference in time. Use the SYSMAN command CONFIGURATION SET TIME to synchronize clocks on the cluster. For complete information on the SYSMAN command CONFIGURATION SET TIME, refer to the HP OpenVMS System Management Utilities Reference Manual.
/BACKUP
/NOBACKUP
Modifies the time value specified with the /BEFORE or the /SINCE qualifier. The /BACKUP qualifier selects files according to the dates of their most recent backups. This qualifier is incompatible with the /CREATED, /EXPIRED, and /MODIFIED qualifiers, which also allow you to select files according to time attributes. If you specify none of these four time qualifiers, the default is the /CREATED qualifier./BEFORE[=time]
/NOBEFORE
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 one of the following qualifiers with the /BEFORE qualifier to indicate the time attribute to be used as the basis for selection: /BACKUP, /CREATED (default), /EXPIRED, or /MODIFIED.For complete information on specifying time values, refer to the OpenVMS User's Manual or the online help topic DCL_Tips (subtopic Date_Time).
/BY_OWNER[=uic]
/NOBY_OWNER
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 User's Manual.
/CHARACTERISTICS=(characteristic[,...])
Specifies the name or numbers of one or more characteristics to be associated with the job. Characteristics can refer to such things as color of ink. If you specify only one characteristic, you can omit the parentheses.A characteristic's number must range from 0 to 127. To see which characteristics have been defined for your system, use the SHOW QUEUE/CHARACTERISTICS command. To see which characteristics are associated with a particular queue, use the SHOW QUEUE/FULL command.
A job can be executed on a queue only if none, some, or all of the characteristics associated with the queue also are associated with the job, that is, the job's characteristics must be a subset of the queue's characteristics. However, if any of the characteristics associated with the job are not associated with the queue, the job remains pending until one or more of the following occurs:
- The characteristics specified with the queue are changed to make the job's characteristics a subset of the queue's characteristics (using, for example, the SET QUEUE/CHARACTERISTICS command).
- The characteristics specified with the job are changed to make the job's characteristics a subset of the queue's characteristics (using, for example, the SET ENTRY/CHARACTERISTICS command).
- The job is moved to a queue on which all the job's characteristics have been specified (using, for example, the SET ENTRY/REQUEUE command).
- The job is deleted (using, for example, the DELETE/ENTRY command).
/CLI=filename
Specifies the command language interpreter (CLI) to be used to process the job. The file specification assumes the device name SYS$SYSTEM: and the file type .EXE (SYS$SYSTEM:filename.EXE). The default CLI is that defined in the user authorization file (UAF).
/CONFIRM
/NOCONFIRM (default)
Controls whether a request is issued before each submit 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. You can abbreviate word responses 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 Return. 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.
/CPUTIME=time
Defines a CPU time limit for the batch job. You can specify time as delta time, 0, INFINITE, or NONE. If the queue on which the job executes has a defined CPUMAXIMUM value, the smaller of the SUBMIT command and queue values is used. If the queue on which the job executes does not have a specified maximum CPU time limit, the smaller of the SUBMIT command and user authorization file (UAF) values is used. If the queue on which the job executes does not have a specified maximum CPU time limit and the UAF has a specified CPU time limit of NONE, either the value 0 or the keyword INFINITE allows unlimited CPU time. If you specify the keyword NONE, the specified queue or UAF value is used. CPU time values must be greater than or equal to the number specified by the system parameter PQL_MCPULM. For more information on specifying CPU time limits, see the CPU Time Limit Specifications and Actions table for the INITIALIZE/QUEUE command./CREATED (default)
/NOCREATED
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 /BACKUP, /EXPIRED, and /MODIFIED qualifiers, which also allow you to select files according to time attributes. If you specify none of these four time qualifiers, the default is the /CREATED qualifier./DELETE
/NODELETE (default)
Positional qualifier.Controls whether files are deleted after processing. If you specify the /DELETE qualifier after the SUBMIT command name, all files in the job are deleted after processing. If you specify the /DELETE qualifier after a file specification, only that file is deleted after it is processed.
For the /DELETE qualifier to work, the protection code on the input files must allow delete (D) access to the user identification code (UIC) of the user submitting the job. If delete (D) access is not allowed, or if any file in the command parameter list cannot be opened as input, command processing stops and no batch job is created.
/EXCLUDE=(filespec[,...])
/NOEXCLUDE
Excludes the specified files from the submit operation. You can include a directory but not a device in the file specification. The asterisk (*) and the percent sign (%) wildcard characters are allowed in the file specification. If you specify only one file, you can omit the parentheses./EXPIRED
/NOEXPIRED
Modifies the time value specified with the /BEFORE or the /SINCE qualifier. The /EXPIRED qualifier selects files according to their expiration dates. (The expiration date is set with the SET FILE/EXPIRATION_DATE command.) The /EXPIRED qualifier is incompatible with the /BACKUP, /CREATED, and /MODIFIED qualifiers, which also allow you to select files according to time attributes. If you specify none of these four time qualifiers, the default is the /CREATED qualifier./HOLD
/NOHOLD (default)
Controls whether the job is made available for immediate processing. The /HOLD qualifier holds the job until it is released by the SET ENTRY/RELEASE or the SET ENTRY/NOHOLD command./IDENTIFY (default)
/NOIDENTIFY
Displays the job name, the queue name, the entry number, and the status of the job when it is queued./KEEP
/NOKEEP
Controls whether the log file is deleted after it is printed; the /NOKEEP qualifier is the default unless the /NOPRINTER qualifier is specified./LOG_FILE[=filespec]
/NOLOG_FILE
Names the log file. The asterisk (*) and the percent sign (%) wildcard characters are not allowed in the file specification.When you use the /LOG_FILE qualifier, the system writes the batch job's output to the file you specify. If you use the /NOLOG_FILE qualifier, no log file is created. By default, a log file is created, is written to the directory defined by the logical name SYS$LOGIN in the UAF, and is given the batch job's name as its file name with a file type of .LOG.
You can use the /LOG_FILE qualifier to write the log file to a different device. Logical names in the file specification are translated in the context of the process that submits the job. The process executing the batch job must have access to the device on which the log file will reside.
If you omit the /LOG_FILE qualifier and specify the /NAME qualifier, the log file is written to a file having the same file name as that specified by the /NAME qualifier with the file type .LOG. When you omit the /LOG_FILE qualifier, the job-name value used with the /NAME qualifier must be a valid file name.
/MODIFIED
/NOMODIFIED
Modifies the time value specified with the /BEFORE or the /SINCE qualifier. The /MODIFIED qualifier selects files according to the dates on which they were last modified. This qualifier is incompatible with the /BACKUP, /CREATED, and /EXPIRED qualifiers, which also allow you to select files according to time attributes. If you specify none of these four time modifiers, the default is the /CREATED qualifier./NAME=job-name
Names the job (and possibly the batch job log file). The job name must be 1 to 39 alphanumeric characters. If characters other than alphanumeric characters, underscores (_), or dollar signs ($) are used in the name, enclose the name in quotation marks (" "). The default job name is the name of the first file in the job.If you omit the /LOG_FILE qualifier, the job-name value must be a valid file name. The SHOW ENTRY and SHOW QUEUE/FULL commands display the job name.
/NOTE=text
Specifies a message string of up to 255 characters. This message string appears as part of the display on a SHOW QUEUE/FULL command and can thus be used to convey information concerning a job. The message specified with the /NOTE qualifier is also printed on the flag page of the log file (if printed)./NOTIFY
/NONOTIFY (default)
Controls whether a message is broadcast to your terminal session when the job is completed or aborted./PARAMETERS=(parameter[,...])
Provides the values of up to eight optional parameters (equated to the symbols P1 to P8, respectively, for each command procedure in the job). The symbols are local to the specified command procedure.Commas (,) separate individual parameters. If you specify only one parameter, you can omit the parentheses.
If the parameter contains spaces, special characters, or lowercase characters, enclose it in quotation marks. The size of the parameter can be from 1 to 255 characters.
/PRINTER[=queue-name](default)
/NOPRINTER
Queues the job log file for printing when your job is completed. The /PRINTER qualifier allows you to specify a particular print queue; the default print queue is SYS$PRINT. If you specify the /NOPRINTER qualifier, the /KEEP qualifier is assumed.When batch and output queues are managed by the same queue manager, the queue manager checks to ensure that the queue specified on the SUBMIT/PRINTER command is an output queue and that the user has access to the output queue. These checks are not made if the batch queue specified by the SUBMIT command and the output queue specified by the /PRINTER qualifier are managed by different queue managers.
If you explicitly specify an output queue for the log file when submitting a batch job, be sure the queue you specify with the /PRINTER qualifier is an output queue and not a batch queue. Also, be sure that you have access to the output queue.
/PRIORITY=n
Requires OPER (operator) or ALTPRI (alter privilege) privilege to specify a priority greater than the queue's maximum scheduling priority.Specifies the job-scheduling priority for the batch job with respect to other jobs in the same queue. The value of n is an integer in the range of 0 to 255, where 0 is the lowest priority and 255 is the highest.
The default value is the value of the system parameter DEFQUEPRI. No privilege is needed to set the priority lower than the queue's maximum scheduling priority, which is the value of the system parameter MAXQUEPRI.
The /PRIORITY qualifier has no effect on the job's process execution priority. The job's process execution priority is determined by the base priority attribute of the INITIALIZE/QUEUE/BASE_PRIORITY command.
/QUEUE=queue-name[:]
Identifies the batch queue on which the job is entered. The default queue is SYS$BATCH./RAD=n (Alpha only)
Specifies the RAD number on which the submitted batch job is to execute.When a job is submitted to a batch queue that does not have a RAD setting, the job will execute using the RAD specified. If the batch queue has a RAD setting, the job will execute using the RAD specified on the queue.
When you specify a RAD on a batch job, the job controller creates the process with the $CREPRC home_rad argument set to the RAD value on the job. If the RAD specified on the job is invalid on the target system, the job fails to execute and the job controller outputs a message to the operator console indicating that a bad RAD was specified. If the bad RAD value matches the RAD setting on the batch queue, the batch queue is stopped and the job remains in the queue.
Supported only on AlphaServer GS series systems.
/REMOTE
Queues the job to SYS$BATCH on the remote node specified. When you use the /REMOTE qualifier, you must include the node name in the file specification.Note that, unlike submitting a job on a local node, multiple command procedures queued by a single SUBMIT/REMOTE command are considered separate jobs.
You can specify only the following qualifiers with the /REMOTE qualifier:
/BACKUP /BEFORE /BY_OWNER /CONFIRM /CREATED /EXCLUDE /EXPIRED /MODIFIED /SINCE /RESTART
/NORESTART (default)
Indicates whether the job restarts after a system failure or after a STOP/QUEUE/REQUEUE command./RETAIN=option
Specifies the circumstances under which you want your jobs to be retained in a queue. When a job is retained in the queue, you can issue the SHOW QUEUE command after the job completes to see the status of the job. Without job retention, no record of a job is left in a queue after a job completes.Use the following options to specify job retention:
- ALWAYS----Holds the job in the queue regardless of the job's completion status.
- DEFAULT----Holds the job in the queue as specified by the queue's retention policy.
- ERROR----Holds the job in the queue only if the job completes unsuccessfully.
- UNTIL=time-value----Holds the job in the queue for the specified length of time, regardless of the job's completion status.
Note
You cannot specify a /NORETAIN qualifier with the SUBMIT command (as system managers can with the commands INITIALIZE/QUEUE, START/QUEUE, and SET QUEUE); however, you can specify /RETAIN=DEFAULT with the SUBMIT command. The default option holds the job in the queue as specified by the queue's retention policy. If the system manager has not specified retention for the queue, the job is not retained.How Job Retention Is Determined
Although you can specify job retention options for your own jobs, the job retention option you specify may be overridden by the job retention option of the queue on which your job executed. If you submit or print a job to a generic queue, the generic queue's job retention setting may also override the job retention option you specify. This section describes how job retention is determined.
An execution queue's job retention setting takes precedence over a generic queue's job retention setting; however, if the job's completion status does not match the job retention setting (if any) on the execution queue, then the generic queue's job retention setting attempts to control job retention. If the job's completion status does not match the job retention setting (if any) on the generic queue, then the user-specified job retention setting is used. Jobs submitted directly to execution queues are not affected by job retention settings on generic queues.
