Job scheduling priority

The priority on the /*PRIORITY statement determines the job's scheduling priority for JES2 managed initiators. If not specified, JES2 calculates this priority based on estimated execution time and the JOBPRTY(n) initialization parameters. You can increase the priority with the PRIOINC parameter up to the PRIOLIM limit on the RDR(nn), Rnnnnn.RD(m), or INTRDR initialization statements.

Jobs in JES2 controlled job classes are queued FIFO within priority within job class. Priority is not used directly to order jobs in WLM managed classes, but can be used as a criteria for determining service class.
