5.3 Some Examples
and predecessor conditions this way makes it easier to evaluate these criteria
statements.
Example 9
In this example, something a little more practical will be shown to show some
of the logic behind determining criteria, which shows the type of thought
process you may go through.
The schedule named IH7BKUP backs up some disks and consists of three jobs:
a daily backup, a weekly backup and a monthly backup.
The daily job IH7D02 normally runs Monday through Thursday.
Consequently, its criteria would be something like:
MON OR TUE OR WED OR THU
What happens on holidays? On holidays, you do not want the job to run. To
omit holidays, revise the criteria as follows:
WDAY AND (MON OR TUE OR WED OR THU)
Now Monday through Thursday also have to be workdays. A more concise
way of writing this criteria statement is as follows:
WDAY AND NOT FRI
Another factor to consider is whether this job has predecessors. In this case, it
does not, so the daily job's selection criteria is now complete.
Next, work on the weekly job. You already know to be conscience of holidays.
If the weekly job runs on Monday through Thursday, the daily job must finish
first. The criteria statement that best describes this is shown following.
WDAY AND FRI
OR
(WDAY AND THU AND HDAY1 AND IH7D2 IH7BKUP)
OR
(WDAY AND WED AND HDAY1 AND HDAY2 AND IH7D2 IH7BKUP)
Since the weekly job will always run on the last workday of the week, you can
simplify the criteria statement preceding as follows:
WDOW-1 AND PRED IH7D2 IH7DBUP
The monthly job IH7M02 runs on the last workday of the month. Its
predecessors vary depending on what day of the week this job runs.
■
If the last workday falls on Monday through Thursday, the monthly job
should wait for the daily backup to complete.
