Automatically controlling the production workload
About this task
IBM Z Workload Scheduler automatically drives the production workload by monitoring the flow of work and by directing the processing of jobs to follow the business priorities established in the plan.
Through its interface to the NetView® program or its management-by-exception ISPF dialog, IBM Z Workload Scheduler can alert the production control specialist to problems in the production workload processing. Furthermore, the NetView® program can automatically trigger IBM Z Workload Scheduler to perform corrective actions in response to these problems.
IBM Z Workload Scheduler automatically:
- Starts and stops started tasks
- Edits job statements: z/OS® JCL or equivalent job statements for other operating environments before submission
- Submits jobs in the specified sequence to the target operating environment every time
- Tracks each scheduled job in the plan
- Determines the success or failure of the jobs
- Displays status information and instructions to guide workstation operators
- Provides automatic recovery of jobs when they end in error, regardless of the operating environment
- Generates processing dates for your job stream run cycles using
rules, such as:
- Every second Tuesday of the month
- Only the last Saturday in June, July, and August
- Every third workday in the user-defined PAYROLL period
- Starts jobs with regard to real resource availability
- Performs data set cleanup in error and rerun situations for the z/OS® workload
- Tailors the JCL for step restarts of z/OS® jobs and started tasks
- Dynamically schedules additional processing in response to unplannable activities
- Provides automatic notification when an updated data set is closed; this can be used to trigger subsequent processing
- Generates alerts when abnormal situations are detected in the workload
IBM Z Workload Scheduler also provides manual control facilities, which are described in Manual control and intervention.
