About Queue Procedures
Queues let you optimize throughput and allocate system resources for scheduled and unscheduled jobs. The CWA queue
manager assigns jobs to queues when all their dependencies have been met, and decides when to launch jobs based
upon the available system resource slots. The maximum number of slots available is determined either by the limit that
you set in the system queue, the sum of each queue’s limit or the sum of each licensed agent’s job limit.

Queues can limit the number of jobs running on a computer or a network of computers at a given time.
If the system is not running at its capacity, a job can run immediately provided that all of its dependencies are met.

structure that includes the following in order of importance:
