AT Job Attribute
•
Users without execute access to the NETBATCH program file (that is, users
who are
not NetBatch supervisors) cannot submit jobs with the AT attribute when
the scheduler’s AT-ALLOWED attribute is set to OFF (the default value). For more
information, see AT-ALLOWED Scheduler Attribute on page 7-18.
•
The scheduler creates temporary executors for all jobs with the AT attribute
and for
all jobs that are operated on by the RUNNOW JOB command. The
scheduler deletes the executors when the jobs finish.
A temporary executor has a scheduler-assigned name of the form
__TEMP_EXEC_job-number, where job-number is the number of the job using
the executor; for example, __TEMP_EXEC_496. The scheduler selects the CPU of
a temporary executor from available CPUs on the scheduler’s node.
•
A job with the AT attribute does not run if any of these conditions exists:
°
The job has the TAPEDRIVES attribute and requires more drives than are
available. For more information about this attribute, see TAPEDRIVES Job
Attribute on page 7-109 and TAPEDRIVES Scheduler Attribute on page 7-110.
°
The job’s class has the attribute INITIATION OFF. This attribute prevents
jobs
belonging to the class from running. To make the jobs available for
execution, change the attribute to INITIATION ON by using the ALTER CLASS
command.
°
The scheduler would exceed its temporary-executors limit by running the job.
In this case, the job runs when the scheduler can create a temporary executor
without exceeding the limit. For more information, see MAX-CONCURRENT-
JOBS Scheduler Attribute on page 7-79.
•
The AFTER, AT, and WAIT job attributes are mutually exclusive. A job can
have
any one of the attributes, but not two or three. Consider job X, whose
attributes include AFTER 17:00. The job runs at 1615 if altered at 1610 by the
command ALTER JOB X, WAIT 00:05. (If you specify more than one of AFTER,
AT, and WAIT in a command, the last attribute specified takes precedence. For
example, job Y submitted at 0900 by the command SUBMIT JOB Y, AFTER 09:45,
WAIT 00:15 runs at 0915.)
•
To display the run time of a job, specify AFTER or AT in an INFO JOB
command. For example:
8} INFO JOB X, AFTER
JOB ATTRIBUTES for X
jobnumber: 26
after: 14DEC94 23:00:00
next-runtime: 14DEC94 23:00:00
BATCHCOM does not display the run time if the job’s state is SPECIAL-n.
