Job Requirements for Jobs in the Queue

Use job requirements to sequence correctly job executions. When jobs are scheduled into the queue for execution, the requirements for this execution of the job (by SCHID) are attached, and the master requirement count (MCNT) is incremented for each requirement. A check is then made to see whether the job requirement can be immediately (initially) satisfied.

Both of the following are satisfied:

• If a nonzero lead time (LEADTM) was specified on the DB.3.2 or DB.1 panel, has the job that is a requirement run in the specified time frame?
• Has the job that is a requirement run after the dependent job ran? (If the requirement uses a zero LEADTM, only the second test is made.)

Note: The times used in lead time checking are obtained from the database. For a job, examine the LAST-RUN DATE/TIME from the LJOB display. For a data set, use the LCTLG,DSN=data.set.name command to examine the last creation date and time CA WA CA 7 Edition recorded for the data set.

Business Value:

This best practice helps ensure the correct sequencing of jobs and improves job processing.
