Submitting work on WTO workstations

This is how IBM Z Workload Scheduler submits operations on WTO workstations:
  • The current plan is locked to prevent other tasks or users from updating the operations.
  • The best candidate for submission is chosen as described in Identifying the order of submission.
  • If the operation has been marked with a NOP, IBM Z Workload Scheduler immediately sets the operation to complete.
  • IBM Z Workload Scheduler gathers the operation text and builds the required WTO message.
  • A submit request is queued, which includes the WTO and the workstation destination.
  • If there are more operations eligible to start, IBM Z Workload Schedulermoves on to the next best candidate. Up to 5 operations can be started.
  • The current plan lock is released.
  • IBM Z Workload Scheduler determines the destination, which can be an XCF link, an NCF link, a TCP/IP link, or blank. If the destination is blank, the WTO is issued on the system that the controller in started on.
  • The workstation reporting attribute for the WTO workstation determines the status to which the operation will be set. Operations defined on workstations with automatic, or manual start and complete reporting will be set to S status. Operations on workstations defined with manual-complete-only reporting are immediately set to C status.

If the JTOPTS keyword QUEUELEN is specified, IBM Z Workload Scheduler starts up to the number of operations defined by QUEUELEN.
