Using Tivoli Workload Scheduler (OPC)
This course teaches how to effectively and confidently use TWSzOS (Tivoli Workload Scheduler for z/OS, also known as OPC - Operations Planning & Control), which is IBM/Tivoli's strategic product for scheduling and managing the enterprise's workload.
On successful completion of this course, attendees will be able to:
- use TWSzOS with confidence
- update TWSzOS databases with the information needed to schedule and run work
- identify the two plans used by TWSzOS
- manage work by checking statuses, re-running jobs and by adding ad-hoc work into the plan
- create and use Special Resources
- use OPSTAT, SRSTAT and ETT
- code Automatic Recovery statements
- describe and use the Restart & Recovery function
