Unicenter CA-Scheduler Job Management for VSE User Guide

1.1 Beginning with the Basics
specific job definition in the database. When you are first implementing
Unicenter CA-Scheduler, you will start by just defining jobs at station 40 (CPU
processing). You will have the time to extend Unicenter CA-Scheduler to other
workstations once it starts automating some of your daily workload.
When defining schedules and jobs to the database, you specify when jobs
should run. Unicenter CA-Scheduler offers two methods for defining when
jobs run: calendars and selection criteria. The calendar method is less versatile
and requires more annual maintenance so will not be discussed here.
The preferred method for scheduling jobs uses Unicenter CA-Scheduler criteria
language. Keywords make it easy to define when to select jobs for the day's
workload:
DAILY
MON OR WED OR FRI
MWF
APRIL AND 1ST
WEEK-DAY
WEEK-END
Every day
On Monday, Wednesday or Friday
On Monday, Wednesday or Friday
On April 1st
On weekdays (Monday - Friday)
On weekends (Saturday and Sunday)
If you say that a schedule runs daily, Unicenter CA-Scheduler workload
includes all the jobs in that schedule every day. That is the most efficient way
to schedule daily jobs because you only specify the frequency once for all jobs
in the schedule.
Not all jobs run on the same days. Jobs within the same schedule do not have
to run every day the schedule does. For example, a schedule may run daily
but some jobs may only run on Monday and others may only run Friday. You
control when exceptional jobs run by defining a more limited frequency on
their job records. Remember that a job can only run on days when its
schedule is selected.
Whether Unicenter CA-Scheduler includes a job in the daily workload depends
on whether its selection criteria are met. The examples preceding show how
self explanatory the criteria language can be. However, its flexibility can
address every scheduling need.
Defining a job to run on Mondays is easy, but what happens when Monday is
a holiday? Unicenter CA-Scheduler knows when holidays occur because they
are defined on a datetable. Therefore, you can ensure that jobs run on the first
work day of every week by scheduling it on WDOW1 instead of Mondays. The
datetable tells Unicenter CA-Scheduler:
