Modifying the current plan

IBM Z Workload Scheduler makes status updates to the plan automatically, using its tracking functions. However, it lets you change the plan manually to reflect unplanned changes to the workload or to the operations environment, which often occur during a shift. For example, you might want to change the priority of a job stream, add unplanned work, or reroute work from one workstation to another. You might also want to correct operational errors manually. Modifying the current plan might be the best way to handle these situations.

You can modify the current plan online. For example, you can:

• Include unexpected jobs or last-minute changes to the plan. IBM Z Workload Scheduler then automatically creates the dependencies for this work.
• Manually modify the status of jobs.
• Delete occurrences of job streams.
• Graphically display job dependencies before you modify them.
• Modify the data in job streams, including the JCL.
• Respond to error situations by:
  • Rerouting jobs
  • Rerunning jobs or occurrences
  • Completing jobs or occurrences
  • Changing jobs or occurrences
• Change the status of workstations by:
  • Rerouting work from one workstation to another
  • Modifying workstation reporting attributes
  • Updating the availability of resources
  • Changing the way resources are handled
• Replan or extend the current plan

In addition to using the dialogs, you can modify the current plan from your own job streams using the program interface or the application programming interface. You can also trigger IBM Z Workload Scheduler to dynamically modify the plan using TSO commands or a batch program. This adds unexpected work automatically to the plan.
