Management of critical path
In addition to the handling of critical jobs based on Workload Manager, IBM Z Workload Scheduler provides the dynamic handling of the critical path calculated by the daily planning batch jobs process.
The critical path is the path, within a network of jobs, with the least slack time.
The slack time, in a critical job predecessor path, is the amount of time that processing of the predecessor jobs can be delayed without exceeding the deadline of a critical job. It is the spare time calculated using the deadline, input arrival, and duration settings of predecessor jobs.
The capabilities include:
- Monitoring of critical job predecessors that are late, long running, or ended with an error. This process uses the same internal logic that the scheduler applies to monitor alert conditions.
- Monitoring of the paths that are consuming their slack time, becoming more critical than the paths calculated at plan generation.
- Enhanced critical jobs monitoring, using ISPF dialog flows.
- Back-end support for new views available using the Dynamic Workload Console.
