5.4 What Is Wrong with These Examples?
Now that you have a basic understanding of the criteria language, try testing
your knowledge by debugging errors in the following criteria statements.
Example 1
Criteria for schedule SCHD01:
MONDAY
Will this job run on Mondays? Not likely because MONDAY is not a
vocabulary word. Instead, Unicenter CA-Scheduler interprets MONDAY as a
job name. Therefore, this job will only be selected when the job MONDAY is
selected. Since you probably do not have a job named MONDAY, the schedule
SCHD01 would never be selected.
The correct criteria vocabulary word is MON.
Example 2
Criteria for job JOBB:
WDOW-1 OR DSN JOBA.DATASET
The intent is to select JOBB on the last workday of the week, but that is not
what happens. Evaluate this statement carefully to see what is wrong. It is
important to evaluate the selection criteria and the predecessor conditions
separately.
What is JOBB's predecessor? The data set JOBA.DATASET must be closed on
the day JOBB is selected before JOBB will be submitted.
When is JOBB selected? Not just on WDOM-1 (the last workday of the month).
Why? Because of the OR. The days on which JOBB is selected will be:
WDOW-1 OR 'keyword-defined parameter'
Unicenter CA-Scheduler cannot translate DSN JOBA.DATASET into a selection
condition, so the second condition defaults to DAILY. Because of the OR, this
job is selected WDOW-1 OR DAILY. How could you rewrite the statement to
run JOBB when intended? Code the criteria statement with an AND instead of
an OR:
WDOW-1 AND DSN JOBA.DATASET
This selects JOBB on the last workday of the month and waits for the data set
JOBA.DATASET to close before submitting JOBB.
