Temporary Predecessors

The predecessor requirements are typically defined on a permanent basis. However, occasionally it is necessary on a one-time basis to add new ones or skip existing ones temporarily.

The DB.3 panels enable the temporary requirements with the NEXT-RUN facility. Any such one-time definitions are automatically deleted from the database after a single execution of the dependent job.

A job executing with any such temporary predecessors, either added or skipped, is identified on LQ job inquiry output as executing with temporary requirements. LJOB,LIST=RQMT, and so forth, also flag individual predecessors as SKIP or ONLY to indicate when these settings exist. QM.2 update panels reflect the letter O to identify a NEXT-RUN=ONLY predecessor. The letter A identifies one added through the ADDRQ top line command. NEXT-RUN=SKIP predecessors do not appear on the QM.2 update panels as they are skipped when the job enters the queue.
