To process the jobs on the job queue, JES2 communicates with an initiator. An initiator is a system program that starts a job to allow it to compete for system resources with other jobs that are already running.Initiators are controlled by JES2 or by MVS workload management (WLM).

JES2 initiators are started by the operator or by JES2 automatically when the system initializes. The initiators select jobs based on the job class(es) that are assigned to the initiator and the priority of the queued jobs. The installation associates each initiator with one or more job classes in a way to encourage the efficient use of avaliable system resources.

WLM initiators are started by the system automatically based on the performance goals, relative importance of the batch workload, and the capacity of the system to do more work. The initiators select jobs based on their service class and the order they were made available for execution.

Check this for differences between JES2 Control of Batch Job Initiation and WLM Control of Batch Job Initiation

check this for What is MVS Workload Management?



Hope this helps...
