2. © 2012 IBM Corporation 2 Workload Automation Agenda Introduction Cross dependencies flow Binding process Shadow job status changes Setup Demo / Q&A

3. © 2012 IBM Corporation 3 Workload Automation Introduction (I) Workload is sometimes spread across different scheduling environments, often located in different sites Scheduling environments managed independently Scheduling environments need to interoperate Using cross dependencies Synchronize activities between different scheduling environments

4. © 2012 IBM Corporation 4 Workload Automation Introduction (II) Job B (Local Engine) logically dependent on Job A (Remote Engine) Job A (on Local Engine) represents Job A (on Remote Engine) Local Engine Tivoli Workload Scheduler Distributed Tivoli Workload Scheduler for z/OS (Session 3603) Remote Engine Tivoli Workload Scheduler Distributed Tivoli Workload Scheduler for z/OS

6. © 2012 IBM Corporation 6 Workload Automation Cross dependencies flow Broker of the local engine sends binding request to the remote engine

7. © 2012 IBM Corporation 7 Workload Automation Cross dependencies flow Broker of the remote engine sends binding response to the local engine Broker of the local engine updates the status of the Shadow Job

8. © 2012 IBM Corporation 8 Workload Automation Cross dependencies flow Remote Job starts running Broker of the remote engine sends the status update to the local engine Broker of the local engine updates the status of the Shadow Job

9. © 2012 IBM Corporation 9 Workload Automation Cross dependencies flow Remote Job completes successfully Broker of the remote engine sends the status update to the local engine Broker of the local engine updates the status of the Shadow Job Successor of the Shadow Job is released
