$T Job - Change a job's class, scheduling priority, or affinity

Function

To change the execution class, priority, or affinity for the specified jobs, or to SPIN either the JESLOG data sets or a particular SYSOUT DD associated with a job.

Parameters

Age|DAys<days | Age|DAys>days

Specifies the age of affected jobs in days. Only jobs more (with DAYS>nn) or less (with DAYS<nn) than the specified number of days in age are affected, The days are counted from the current hour.

Age is computed by subtracting the job's "begin time" from the current time. That is, the time that the job was initially added to its current queue is the "begin time" except:

• The "begin time" for jobs that are actively running is the same as the time the command was entered. That is, the age for running jobs is always zero days and hours.
• The "begin time" for jobs in the OUTPUT or HARDCPY queue is the time that the job ended execution. If the job does not run, then the time is the time that the job was placed in its prior queue.

BUSY=

Specifies one of the following:

• The system name or number on which the job is busy. Note that you can specify a value of 0 to indicate the job is not busy. You can also specify values above 32 to match systems with invalid values in the BUSY value (for example, $TJOBQ,BUSY>32)
• YES or ANY, indicating that all busy jobs are to match
• NO or NONE, indicating that all non-busy jobs are to match

CARDS=cards

Specifies the number of input cards associated with the job.

CC=(ABEND|ABENDED|CANcelled|CNVT_abend|CODE| COMPleted|ENDed_by_cc|EOM_failure|FLUSHED|JCLerror| SECurity_failure|TYPE)

Specifies the completion information associated with the job.

ABENDED

Specifies only jobs which have abnormally ended.

ABEND

Specifies the ABEND code associated with the job's termination.

CANcelled

Specifies only jobs which were cancelled by the operator.

CNVT_abend

Specifies only jobs which have abnormally ended during the conversion phase.

CNVT_ERROR

Specifies job that failed due to a converter error.

CODE

Specifies the last (or highest) completion code of steps in the job.

COMPleted

Specifies only jobs which completed.

ENDed_by_cc

Specifies only jobs which were ended by a step completion code.

EOM_failure

Specifies only jobs which failed in end-of-memory processing.

FLUSHED

The job was cancelled (flushed) and is no longer eligible to run.

JCLerror

Specifies jobs which did not execute due to a JCL error.

SECurity_failure

Specifies jobs which failed security validation.

SYSTEM_FAILURE

Specifies jobs that failed due to system failure.

Class=class

The new class that is assigned to the specified job(s). You may not move jobs in the execution-batch-processing class to a non-execution batch processing class, and vice versa. Note that wildcard characters can be specified when used as a selection limiting keyword: see Using wildcards for details.

1. When changing the job class, be sure the new job class is defined on the member on which the job executes.
2. The class change resulting from this command affects JES2 job scheduling only. If you move a job from class P to class S with this command, the job is eligible for initiators processing class S jobs, and is no longer eligible for class P initiator processing.

   If you enter the command before the job's conversion, the class remains P for conversion purposes, but is then scheduled for an initiator selecting class S jobs.

   If you enter the command after conversion, job attributes determined by class during conversion (for example, default region size) are unchanged, but the job is scheduled for an initiator selecting class S jobs.

3. If these values are modified for a job in execution note that the service class is not changed. If these changes would result in a different service class this takes effect only if the job is restarted. The service class of an executing job can be modified only by explicitly changing the service class.

CMDauth=cmdauth

Only the jobs that can be affected from the specified remote(s) or node(s) will be changed. The valid specifications are:

LOCAL|ANYLOCAL

Only the local devices at the local node can affect the output.

Nnnnn|nodename

Only local devices at the specified node can affect the output.

Rnnnn

Only the specified remote device can affect the output.

NnnnnRnnnn|nodename.Rnnnn

Only the specified remote device at the specified remote node can affect the output.

destid

A destid corresponding to any of the above remote devices.

Note: Specification of the CMDAUTH filter does not override the authority of the console from which the command is issued; both the authority of the console and the specified CMDAUTH filter must match for the job to be affected.

DELAY={BUSY_ON_HOLD|HOLD|LIMIT|LOCKED| No|QUEUE_ERROR|SCHENV|SECLABEL|SPOOLS_NOT_AVAILABLE|SYSAFF| MEMBER_STATUS|Yes}

Specifies reasons why a pre-execution job will not enter execution:

BUSY_ON_DEVICE

The job will not execute because it is busy on a device (such as an offload job transmitter).

HOLD

The job will not execute because it is held, its job class is held, or another job with the same jobname is executing.

LIMIT

The job will not execute because the job class execution limit has been reached (as specified by JOBCLASS XEQCOUNT=(MAX=)).

LOCKED

The job will not execute because it's being updated by JES2.

SECLABEL

The security label (SECLABEL) assigned to the job is not defined as active on any member that is active.

SYSAFF

Each of the members for which the job has affinity (SYSAFF) is inactive, or the job has specified independent state, and the JES2 member is not independent (IND=NO).

SCHENV

The job's scheduling environment is not available on any member, or is available only on systems where JES2 is inactive. Use the $DJ'jobname',LONG command to find out what scheduling environment a job requires. Then use the D WLM,SCHENV=schenv-name command to find out the current status of the scheduling environment on each system in the sysplex.

The SCHENV state masks other reasons why the job might be ineligible to run, such as the $P and $P XEQ commands having been issued. Also, note that the SCHENV delay is detected only after a job goes through conversion. If a job is delayed prior to conversion due to system affinity requirements, scheduling environments are not considered in determining delay status.

MEMBER_STATUS

A combination of system affinity, scheduling environment and SECLABEL restrictions are preventing the job from running, or, other member states prevent the job from running on systems where the job is otherwise eligible. These states include:

• $P command has been issued
• $P XEQ command has been issued
• BOSS=NO (used in a poly-JES environment only)

When used as a command filter, the string MEMBER_STATUS matches on jobs delayed for SYSAFF, SCHENV, SECLABEL, or MEMBER_STATUS. To get detail on why a job is delayed, display job status with the $DJ'jobname',LONG command or display member status with the $DJMEMBER(member-name) command.

Yes

Specifies only jobs which are delayed for any of the above reasons.

No

Specifies only jobs which are not delayed for any of the above reasons.

H|Hours=hours

Specifies the age of affected jobs in hours. Only jobs more (with HOURS>nn) or less (with HOURS<nn) than the specified number of hours in age are affected.

HOLD={ALL|ARM|DUP|JOB|NONE}

Only jobs with the specified hold attributes are modified.

ALL

Changes jobs held by the $H A command.

ARM

Changes jobs which are held awaiting a restart through ARM.

DUP

Change jobs held for a duplicate job name.

JOB

Change jobs held by the $H J command, TYPRUN=HOLD, TYPRUN=JCLHOLD, or held due to error.

NONE

Change jobs which are not held.

JESCANCEL={ALLOWED|RESTRICTED}

Sets the JESCANCEL property for this job. ALLOWED indicates that canceling the job while it is queued for or active in execution is allowed. RESTRICTED indicates if the job is queued or active in execution it cannot be canceled. This applies to the following ways to cancel a job (or STC or TSU).

• $C® command
• $C,P command
• Cancel option of the job modify SSI 85
• TSO CANCEL command (via SSI 2)
  Note: TSO CANCEL (SSI 2) cannot be used to cancel active started tasks (STCs) or time sharing users (TSUs) regardless of the JESCANCEL setting.

NHOLD=-

If job is DJC = YES, then NHOLD value is decremented by 1. If NHOLD value transitions to zero, then job enters into execution.

NHOLD=+

If job is DJC = YES, then NHOLD value is incremented by 1 up to 32767.

NHOLD=0

If job is DJC =YES and NHOLD is greater than 0, then NHOLD is set to zero and the job enters execution.

job

Specifies 1 to 8 alphanumeric, special ($, #, or @) or wildcard characters (or a combination of them) that can be used to select a subset of jobs whose job name matches this combination of characters (mask).

‘job'

The name of the job that is to be changed. This name must appear as coded on the JOB statement and must be enclosed in apostrophes. If more than one job exists with this name, no action is taken.

Job

A Batch job or range of batch jobs is to be changed.

JC|JOBCORR=job correlator

Specifies a combination of 1-64 alphanumeric, special (colon, period or underscore) and wildcard characters that can be used to select a subset of jobs that have a matching job correlator. For a description of wildcard characters, refer to Using wildcards.

JOBGROUP=jobgroupname

Specifies 1 to 8 alphanumeric, special ($, #, or @) or wildcard characters (or a combination of them) that can be used to select a subset of jobs whose job group name matches this combination of characters (mask).

JOBID=jobid

Select matching character JOBID associated with the job to be displayed. JOBIDs are of the form Jnnnnnnn, JOBnnnnn, Snnnnnnn, STCnnnnn, Tnnnnnnn, and TSUnnnnn. Generics characters are supported in the jobid field.

JOBID=jobid

Select matching character JOBID associated with the job that owns the output group to be displayed. JOBIDs are of the form Jnnnnnnn, JOBnnnnn, Snnnnnnn, STCnnnnn, Tnnnnnnn, and TSUnnnnn. Generic characters are supported in the jobid field

JOBMASK|JM=jobmask

Specifies 1 to 8 alphanumeric, special ($, #, or @) or wildcard characters (or a combination of them) that can be used to select a subset of jobs whose job name matches this combination of characters (mask). For a description of wild cards, see Using wildcards.

Note:

1. This is a positional parameter. Specify this following the job_id (JOB, STC, or TSU) or JOBQ parameter.
2. The JOBMASK parameter is not valid with the ‘jobname' parameter.

JOBQ|JQ

Specifies all jobs, STCs, and TSUs across the MAS for processing.

LIMITS_IMPACT={No|Yes}

Select jobs that exceeded their job resource limit and have been impacted by resource limit action other than NONE (Yes) or jobs that did not have that impact (No).
See Chapter 9. JES2 Resource Limit Management in z/OS® JES2 Initialization and Tuning Guide for more information about job resource limits.

LIMITS_RAISED={No|Yes}

Select jobs that have been a target of $T Job command with RAISE_LIMITS keyword (Yes) or jobs that have not been impacted by that command (No).
See RAISE_LIMITS keyword of $T Job command in this book.

OFFS=(n[,n,n...])|(+n,[n,n...])|(-n,[n,n...])|0

Specifies updates to the archival status of this job. Jobs will be marked as already offloaded for all offload device numbers that were specified and as not offloaded for all offload device numbers not specified.

Specifying + or - before the offload device number(s) updates offload status of the job for only the specified offload device numbers. Specifying + marks the output as offloaded and specifying - marks it as not having been offloaded by the specified offload device number(s). Use this option to allow offloading of job(s) that have been already been offloaded or to prevent offloading of jobs by an offload device.

Priority=priority

The new priority (0-15), or the value that is added to (+n) or subtracted from (-n) the present priority for the specified job(s). If the job priority is adjusted to a value less than zero, zero is assumed. If the priority is adjusted to a value greater than 15, JES2 assigns a maximum priority. This maximum priority is greater than 15, which allows the operator to selectively run jobs at a priority higher than any jobs submitted with a priority of 15.

Note:

1. Even though a job has been assigned a maximum priority, JES displays the job priority as 15.
2. If these values are modified for a job in execution note that the service class is not changed. If these changes would result in a different service class this takes effect only if the job is restarted. The service class of an executing job can be modified only by explicitly changing the service class.

Queue={CNV|INPUT|OUT|PPU|PURGE|RCV| SETUP|SPIN|XEQ|XMT}

Only jobs on the specified job queue are to be modified.

CNV

Only jobs awaiting conversion are to be modified.

INPUT

Only jobs on the JES2 $INPUT queue are to be modified.

OUT

Only jobs awaiting output processing are to be modified.

PPU

Only jobs awaiting print/punch processing are to be modified.

PURGE

Only jobs awaiting purge processing are to be modified.

RCV

Only jobs on the JES2 $RECEIVE queue are to be modified.

SETUP

Only jobs on the JES2 $SETUP queue are to be modified.

SPIN

Only jobs awaiting spin processing are to be modified.

XEQ

Only jobs awaiting execution are to be modified.

XMT

Only jobs queued for network transmission are to be modified.

RAISE_LIMITS

Requests temporary increase of the resource limits of the specified job. Resource limits of the job for all resource types supported by the JES2 resource limit function, are raised by 10 percentage points. This allows job to consume more JES2 resources before the job is affected by the new limit.

The command can only be used for a job that is active. The increased limits are only in effect while the job is active. After job terminates and exits execution phase, the limits of the job revert to the values specified when the job was submitted.

This command can be used at any time however the most common use of the command is when job reaches some resource limit and is waiting for operator action, which is signaled by the message HASP1806. After the resource limits of the job are increased, job is allowed to continue and consume more JES2 resources. If the job exceeds the new increased limits, the configured action will be applied to the job.

When this command changes resource limits of the active job, results are reported by HASP1809 message. In addition, message HASP1810 is added to the joblog of the target job.

For more information about the JES2 resource limits function, see Chapter 9. JES2 Resource Limit Management in z/OS JES2 Initialization and Tuning Guide.

REBUILD={No|Yes}

Jobs on the rebuild queue are to be changed (Yes) or not changed (No).

RESGROUP=resgroupname

Specifies 1 to 8 alphanumeric or wildcard characters (or a combination of them) that can be used to select a subset of jobs whose resource group name matches this combination of characters (mask).

SCHENV=schenv

Specifies the scheduling environment associated with the job.

SCHENV_AFF=member

Specifies the JES2 MAS members on which the scheduling environment for this job is available.

SECLABEL=seclabel

Specifies the security label associated with the job.

SECLABEL_AFF=member

Specifies the JES2 MAS members on which the SECLABEL for this job is available but only if the RACF® SECLABEL_BY_SYS is also active.

SPIN[,DDname=jxxxxxxx]

Requests SPIN processing for the specified job. If DDname= is not specified, all eligible data sets (including JESMSGLG and JESYSMSG) are immediately spun off for the job. If DDname= is specified, the specified SYSOUT DD is immediately spun off for the job. The DDname= value specified must represent a SYSOUT data set that was allocated with a SPIN= attribute that allows it to be spun. For more information, see the description of the DD SPIN= keyword in the z/OS MVS JCL Reference.

Note: When the JESLOG data sets are spun, the message, $HASP138 JESLOG SPIN REQUESTED BY OPERATOR is placed in the JESMSGLG and JESYSMSG data sets. $HASP138 is not placed in the console or SYSLOG.

SPL|SPOOL={Percent|%|Tgs|Volumes}

Only jobs with specific SPOOL characteristics are to be changed:

Percent|%

Only jobs using more (with %>nn) or less (with %<nn) than the specified percentage of the total available spool space are to be changed.

Tgs

Only jobs using more (with Tgs>nn) or less (with Tgs<nn) than the specified number of track groups are to be changed.

Volumes=(v1,v2,...)

Only jobs which have allocated spool space on the specified spool volume(s) are to be changed.

SRVCLASS=srvclass

Change the WLM service class for the job to the specified service class. If the service class keyword is specified without a service class, the job is reclassified. See the MVS RESET command RESUME keyword description for more information.

Stc

A started task or range of started tasks is to be changed.

Sysaff

Changes the system affinity of the job. Up to 33 entries can be coded by using a combination of the following values:

memname|*

Specifies the identifier (one to four characters using A-Z, 0-9, $, #, and @) of a member in the JES2 multi-access spool configuration that has affinity for the job. Use an asterisk to specify the member that executes the command.

ANY

Specifies jobs that are eligible to run on any member in the JES2 multi-access spool configuration. If you specify ANY followed by the IND parameter, they must be separated by a comma and the list must be enclosed in parentheses, for example, (ANY,IND).

+|-

The subsequent memnames, ANY, and IND, are to be added to (+) or deleted from (-) the current list of affinities that are associated with this job. If neither + nor – qualifier is specified anywhere in the SYSAFF parameter, the affinity of the job is set explicitly to the affinity entries that are specified in the SYSAFF parameter. If a + or – qualifier is specified on the first entry in a list of entries, the current affinity list of this job is affected. A + or – qualifier on an entry will add (+) or delete (-) that entry from the current affinity list of this job. If the first entry in a list of entries has no + or - qualifier, the current affinity list of this job will be replaced with the affinities that are determined by processing the SYSAFF parameter. A + or – qualifier on a subsequent entry will add (+) or delete (-) that entry from the replacement list. When a + or - qualifier is encountered in the SYSAFF parameter, the qualifier becomes the active qualifier that is applied to each of the following entries in the list until a different qualifier, or the keyword ANY is encountered in the list.

Note: If you specify IND without any member names (memname), you must specify + or - qualifier.

IND

Specifies the job that must be executed on a processor operating in independent mode. IND cannot be specified by itself.

Note: The processing of the SYSAFF parameter must result in at least one member that is eligible to execute this job. Otherwise, the command will be rejected.

Tsu

A time-sharing user or range of time-sharing users is to be changed.

TYPE={JOB|STC|TSU}

Indicates whether only batch jobs (JOB), started tasks (STC), or time-sharing users (TSU) are to be changed.

USERID=userid

Specifies the userid associated with the job.

XEQHours=hours

Specifies the number of hours that a job has been executing. Only jobs that run more (with XEQH>nn) or less (with XEQH<nn) than the specified number of hours are affected, with the restriction that requires that the jobs must be executing.

XEQNode=xeqnode

Only jobs which are destined to execute at the specified node, or which have already executed at the specified node, are to be changed. The node name may be specified using the decimal node number (Nnnnnn) or an EBCDIC node name.

Authority Required

This command requires job authority. The description of the $T RDRnn command explains how to ensure that the authority of the appropriate MVS system command group is assigned.

This command requires update security access authority. For a description of assigning command input authority, see z/OS JES2 Initialization and Tuning Guide.

Scope

MAS-wide. This command has an effect across the entire MAS.

Messages

The $HASP890 message displays the current status of the specified job.

The $HASP003 message indicates that the command was improperly specified.
