HIJBNUM Changes

The HIJBNUM parameter specifies the highest permitted CA 7 assigned job number. You can change the HIJBNUM value on any valid start type (WARM, ERST, CKPT, COLD, or FORM).

Note: Before you decrease the HIJBNUM value on a WARM or ERST type start, consider the following items:

• Some jobs in the status queues can already have job numbers greater than the new HIJBNUM value.

  These jobs process normally through the queues, but no jobs entering the queues after startup are assigned job numbers greater than HIJBNUM.

  The size of some in-memory queue tables is typically based on the HIJBNUM value. For this execution of CA WA CA 7 Edition, the size is based on the greater of HIJBNUM and the highest job number present in the queues at startup time.

• At startup, if the next job number to assign is greater than HIJBNUM, it is reset to the lowest available job number.
