Unicenter CA-Scheduler Job Management for VSE User Guide

The payroll department's month-end jobs could
make up a schedule. The schedules and jobs
selected each day comprise the workload.
SCR. Schedule criteria record. This record
determines when a schedule is to be selected for
processing and lists the predecessors for the schedule.
selection. How Unicenter CA-Scheduler determines
the day's workload at autoscan time. Unicenter
CA-Scheduler reviews the criteria statements of
every schedule to see which ones qualify for
inclusion in the day's workload. Every time
Unicenter CA-Scheduler selects a schedule that
qualifies, it scans the criteria statements of every job
in that schedule. Jobs are selected if:
■
■
■
■
They specify a calendar which defines that day
as a workday or
A reason in the criteria statement is true that
day or
No criteria record exists for that job or
One reason in the criteria statement is the
keyword REQUESTED
Jobs can only be selected when the schedules they
belong to are selected. All the important terms used
in this definition are also defined in this glossary.
selection criteria. There are two distinct meanings:
1. All the reasons why a job or schedule can be
selected as defined in its criteria statement. If a
calendar is also defined for a schedule or job,
Unicenter CA-Scheduler bases selection on the
calendar and ignores the selection criteria. See
selection.
2. The keywords that are used in the maintenance
panels to limit the directory to be displayed.
selection-defined explicit predecessor. A
predecessor that also defines selection criteria. They
are schedule or job names used with or without the
keywords SCD and START. When START or SCD is
used with PRED or DOS, the result is a
keyword-defined explicit predecessor that is ignored
during the selection process.
selection criteria. All the reasons why a job or
schedule can be selected as defined in its criteria
statement. If a calendar is also defined for a schedule
or job, Unicenter CA-Scheduler bases selection on
the calendar and ignores the selection criteria. See
selection.
sequence enforcement. Making sure schedules and
jobs are processed in the right order. See implicit
predecessor.
shared DASD. A hardware configuration that
allows two or more operating systems to use the
same disk files. This situation allows several
operating systems to use the same set of Unicenter
CA-Scheduler files at the same time. However,
when operating systems share Unicenter
CA-Scheduler files, it does not imply that they also
share spool files.
simulation. Answers the question "what if." It
shows how processing is affected by changes in
workload or hardware failure. Simulation also totals
how long each job usually takes to project when the
workload is likely to finish.
SIR. Schedule information record. This record
provides descriptive information for a schedule.
SMR. Schedule message record. This record
determines who receives messages when a schedule
begins, ends, or starts late.
spin locks. The method Unicenter CA-Scheduler
uses to protect the integrity of its files when two or
more operating systems share them. See shared
DASD.
SRC. Schedule reason code record. This record is
used assign time specifications which vary according
to the reason a schedule is selected for processing.
staging. Unicenter CA-Scheduler's three-step
process for tailoring production JCL:
1. First, Unicenter CA-Scheduler automatically
copies the production JCL for jobs that require
staging into its staging library.
2. Then users modify that copy of the JCL as
needed (the original production JCL is not
changed).
3. When the JCL has been modified and that
pre-CPU job has been posted as ENDED,
Unicenter CA-Scheduler automatically submits
the modified JCL to the operating system when
that job becomes available for processing.
Also called JCL setup.
