How work is selected for automatic submission

This chapter describes how IBM Z Workload Scheduler decides the run order of operations on computer, nonreporting, and WTO workstations.

IBM Z Workload Scheduler builds the current plan from information in the long-term plan, calendar database, application description database, workstation database, and resource database. When the current plan is created, IBM Z Workload Scheduler assigns start times to each operation. These start times are IBM Z Workload Scheduler's estimates of when the operations should start. They are not the actual times when IBM Z Workload Scheduler will start the operations, unless the operation has been designated as a time-dependent operation. Here, the start time is the time when IBM Z Workload Scheduler will attempt to start the operation. (See Creating time-dependent operations.) This is because IBM Z Workload Scheduler attempts to maximize throughput in your system by starting as many operations as soon as possible.
