- ACCTFLD=IGNORE|REQUIRED|OPTIONAL
- Specifies whether the JES2 form of the accounting information
(the job accounting number and room number) is required (REQUIRED),
ignored by JES2 if present (IGNORE), or is not required but used by
JES2 if present (OPTIONAL) on the JCL JOB statement for this job.
If ACCTFLD=REQUIRED is coded, JES2 cancels your job when either
of the accounting field parameters is missing and issues message $HASP110 jobid jobname ILLEGAL JOB CARD.
Modification: $T JOBDEF operator command.
- BAD_JOBNAME_CHAR=c|?
- Specifies the character to use in place of invalid characters
in a jobname. This translation is used for JES2 commands and displays RACF® entity names too. Valid values are: A-Z,0-9, $, #, @, /,
+, :, ?, _, -, !
Modification: $T JOBDEF operator command
or JES2 cold start
 CISUB_PER_AS=nn|5 - Specifies the nn number of converter/interpreter
subtasks (1-25) that are run in each of the jesxCIxx address spaces when INTERPRET=JES is specified.
Valid values are 1-25 (25 being the maximum number of converter PCEs
that can be specified on PCEDEF).
Modification: $T JOBDEF
operator command
- CNVT_ENQ=WAIT|FAIL
- Specifies how the system should process jobs that request JCLLIB
data sets that are already enqueued at job conversion time.
- WAIT
- Indicates that system will allow the job to wait for the enqueued
data set.
- FAIL
- Indicates that the system will fail (with a JCL error) a job that
requests an unavailable JCLLIB data set.
Modification: $T JOBDEF
operator command or cold start. Note that this parameter cannot be
modified through a hot start, quick start, or single-member warm start,
such that the parameter value in effect before the termination will
be used.
- CNVT_SCHENV=HONOR|IGNORE
- Specifies whether the availability of a scheduling environment
that is associated with a job controls which member a job converts
on. If CNVT_SCHENV=HONOR is specified, then a job can only convert
on a system where the scheduling environment associated with the job
is available.
Modification: $T JOBDEF operator command. This
parameter cannot be modified by a hot start, quick start or single-member
warm start.
- DUPL_JOB=NODELAY|DELAY
- Specifies whether or not JES2 is allowed to concurrently execute
batch jobs with the same name in the same MAS.
- DELAY
- Do not allow JES2 to execute batch jobs with the same name in
the same MAS at the same time.
- NODELAY
- Allow JES2 to execute batch jobs with the same name in the same
MAS at the same time.
Modification: $T JOBDEF operator
command or JES2 cold start.
- CNVT_ENQ=WAIT|FAIL
- Specifies how the system should process jobs that request JCLLIB
data sets that are already enqueued at job conversion time.
- WAIT
- Indicates that system will allow the job to wait for the enqueued
data set.
- FAIL
- Indicates that the system will fail (with a JCL error) a job that
requests an unavailable JCLLIB data set.
Modification: $T JOBDEF
operator command or cold start. Note that this parameter cannot be
modified through a hot start, quick start, or single-member warm start,
such that the parameter value in effect before the termination will
be used.
- DEF_CLASS=class|A
- Specifies a default class that JES2 will use if a non-valid class
is discovered during processing. The specified class must be a defined
and active batch job class. The specified class cannot be set to ACTIVE=NO,
and cannot be deleted. The following examples show when the
default class would be used:
- When a job is submitted with a CLASS= value that is not valid.
The job is failed, but this class is associated with the job for later
processing.
- When a job class is deleted that is associated with the INTRDR
statement as CLASS=. The INTRDR CLASS value is set to this value.
- During initialization processing, when the CLASS= value that is
specified for a reader (INTRDR, local or remote) is not valid and
the operator continues initialization.
The default is A.Modification: $T JOBDEF
operator command or a JES2 all-member warm start.
Scope: MAS-wide
- INTERPRET=INIT|JES
- Specifies when JES2 calls the MVS interpreter to process a job.
The INTERPRET parameter is only valid when JES2 is in z11 mode. The
INTERPRET parameter is not supported in z2 mode.
- INIT
- Specifies to call the interpreter when the job is selected for
execution by an initiator. Invoking the interpreter in the initiator
is the traditional JES2 processing method.
- JES
- Specifies for JES2 to call the interpreter at the end of conversion
processing. The following functions are available if processing is
done under JES (after conversion):
- Earlier detection of JCL errors that are detected by the MVS interpreter.
This allows errors to be detected even if the job never executes for
TYPRUN=.
- Processing of JESDS OUTPUT statements to control data set attributes,
even if the job never executes.
Note: Specifying INTERPRET=JES causes EXIT 60 to be driven instead
of exit 6. If you use exit 6, you might need to also provide similar
function in exit 60 before setting interpret=JES.
Modification: $T JOBDEF
operator command.
- JNUMWARN=nnn|80
- Specifies the percentage (1–99) of assignable
job numbers (specified through the RANGE= parameter) that have been
used for jobs submitted at the local node at which the operator is
to be alerted with message $HASP050 JES2 RESOURCE SHORTAGE.
Modification: $T JOBDEF operator command. Note that this parameter
cannot be modified through a hot start, quick start, or single-member
warm start.
- JOBNUM=nnnnn|1000
- Specifies the maximum number (must be no greater than 400000) of jobs that can be in the JES2 job queue
at any given time. This value includes all TSU, STC jobs, and batch
jobs.
Performance Consideration: Specify JOBNUM= large
enough to accommodate all jobs (including batch jobs, started tasks, and
TSO/E logons) in the system at all phases of processing. Be careful
not to specify a value that is too small.
If you use the $T
JOBDEF command to increase JOBNUM=, only do so when you can allow
your system to experience temporary performance degradation while
all JES2 systems read the checkpoint data set.
Note: Use this parameter to increase the limit for the JNUM
resource that is reported on the HASP050 message.
Modification: $T JOBDEF operator command to increase
or decrease the number of jobs.
- JOBWARN=nnn|80
- Specifies the percent (1–99) usage threshold of
available job queue elements (JQEs) at which the operator is to be
alerted with message $HASP050 JES2 RESOURCE SHORTAGE. If you specify
0, no alert will be given.
Modification: $T
JOBDEF operator command. Note that this parameter cannot be modified
through a hot start, quick start, or single-member warm start.
- LOGMSG=ASIS|FOLD
- Specifies whether the messages issued by JES2 and written at job
JCL converter time are mixed-case (ASIS) or uppercase (FOLD). The
default is ASIS.
Modification: $T JOBDEF operator
command or JES2 start.
- PRTYHIGH=nn|10
- Specifies the upper priority limit (0-15) to be associated with
the JES2 job priority-aging feature. A job will not be priority-aged
if its priority is (or becomes) greater than or equal to the value
specified in this parameter. Jobs on the $HARDCPY queue are not priority
aged.
Modification: $T JOBDEF operator command. Note
that this parameter cannot be modified through a hot start, quick
start, or single-member warm start.
- PRTYJECL=YES|NO
- Specifies whether the JES2 /*PRIORITY control statement is to
be supported (YES) or ignored (NO).
Modification: $T JOBDEF
operator command.
- PRTYJOB=YES|NO
- Specifies whether the priority specified (PRTY= keyword) on the
JCL JOB statement is supported (YES) or ignored (NO).
Modification: $T JOBDEF operator command.
- PRTYLOW=nn|5
- Specifies the lower priority limit (0-15) to be associated with
the JES2 job priority-aging feature. A job will not be priority-aged
unless its priority is initially equal to or greater than this value.
Jobs on the $HARDCPY queue are not priority aged. (See the PRTYRATE=
and PRTYHIGH= parameters on this initialization statement for additional
information.)
Modification: $T JOBDEF operator command.
Note that this parameter cannot be modified through a hot start,
quick start, or single-member warm start.
- PRTYRATE=nnnn|0
- Specifies the number
(0-1440) of time periods into which a 24-hour day is to be divided
for use in increasing a job's priority by the JES2 priority-aging
feature. For example, if 3 is specified, a job's priority will be
increased by one for every 8 hours it remains in the system. However,
a job's priority will not be incremented unless it is at least equal
to the value specified in the PRTYLOW= parameter; nor will a job's
priority be increased above the value specified in the PRTYHIGH= parameter.
If 0 is specified, the values specified in the PRTYLOW= and PRTYHIGH=
parameters are ignored. See z/OS JES2 Initialization and Tuning Guide for a discussion of this processing.
If a job's priority is
specified on a /*PRIORITY control statement or through the PRTY parameters
on the JOB card, the job will be priority-aged if its priority is
eligible. See the JOBPRTY statement (JOBPRTY= parameter) and OUTPRTY
statement (RECORD=, PAGE=, and PRIORITY= parameters) in this chapter for
additional information.) Jobs in WLM-mode job classes are not priority
aged.
Modification: $T JOBDEF operator command. Note
that this parameter cannot be modified through a hot start, quick
start, or single-member warm start.
- RANGE=nnnnn[,mmmmm]|1,9999
- Specifies the range of numbers (1 through 999999) which JES2 will
assign as JOBIDs to jobs which originated on the local node.
The
integer n specifies the lowest number (1 through 999999) which will
be assigned as a JES2 job identifier for jobs originating locally.
The integer m specifies the highest number (n+10 through 999999)
which will be assigned as a JES2 job identifier to jobs originating
locally. Note that setting the upper limit above 99,999
will cause the JOBID format to change from CCCNNNNN to C0NNNNNN where CCC is either JOB, STC, or TSU, and C is J, S,
or T. NNNNN or NNNNNN is a number.
Note: Use this parameter to increase the limit for the JNUM
resource that is reported on the HASP050 message.
Modification: $T JOBDEF operator command or cold start. If you modify this parameter
and then restart JES2 with a warm or hot start, the parameter value
in effect before the termination will be used.
- RASSIGN=No|Yes
- Specifies whether job numbers outside of the RANGE
definition can be assigned to jobs received through NJE or spool reload.
YES= Jobs with original job numbers outside JOBDEF RANGE will retain
their original job number, if possible. NO= Jobs with original job
numbers outside JOBDEF RANGE will always be assigned a new job number
within the range.
