The program interface (PIF)
About this task
This chapter describes the IBM Workload Scheduler for z/OS program interface (PIF), which lets a user-written program issue various requests to the IBM Workload Scheduler for z/OS subsystem. For example, you can automate actions that you perform through the IBM Workload Scheduler for z/OS dialogs.
The
program interface supports these basic requests:
- Database requests
-
- Read and update information from the application description and operator instruction databases.
- Read information from the workstation description and calendar databases.
- LTP requests
- Read and update occurrences in the LTP data set.
- Current plan requests
- Read and update this information in the current plan data set:
- Occurrences
- Operations
- Workstations
The program interface is supported using an IBM Workload Scheduler for z/OS-supplied communication subroutine, EQQYCOM.
