Batch operations and workload schedulers
How overnight batch is planned, run and repaired with the schedulers banks actually use: Control-M, IBM Z Workload Scheduler (TWSz), IBM Workload Scheduler (IWS) with the Dynamic Workload Console, AutoSys, Stonebranch and others.
What you will be able to do
- Explain what a workload scheduler adds to JCL: dependencies, calendars, resources and the daily plan
- Find your way around Control-M, TWSz/IWS with DWC, AutoSys and Stonebranch
- Use the same core actions in any tool: hold, release, rerun, force complete and add ad hoc work
- Run a batch night safely: watch the critical path, fix failures and communicate
Lessons
- How workload scheduling worksJCL describes one job. A workload scheduler decides when thousands of jobs run, in what order, on which days, and what happens when one fails. Every scheduler — Control-M, TWSz,…
- Control-MControl-M from BMC is one of the most widely used workload schedulers. It runs and monitors jobs on z/OS, Linux, Windows and cloud services from one place, and links them with…
- IBM Z Workload Scheduler, IWS and DWCIBM's scheduler family has two members. IBM Z Workload Scheduler — still widely called TWSz or OPC — schedules mainframe batch. IBM Workload Scheduler (IWS) schedules distributed…
- AutoSys, Stonebranch and other schedulersNot every site uses Control-M or IBM. AutoSys and Stonebranch are common in banks, and older mainframe shops may run CA 7, ESP or Zeke. The ideas are the same; the words and…
- Running and fixing a batch nightAn operator's night is about one thing: getting the right jobs finished correctly before the business deadline. That means watching the critical path, fixing failures in the…
