The program interface (PIF)

This chapter describes the IBM Z Workload Scheduler program interface (PIF), which lets a user-written program issue various requests to the IBM Z Workload Scheduler subsystem. For example, you can automate actions that you perform through the IBM Z Workload Scheduler 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 Z Workload Scheduler-supplied communication subroutine, EQQYCOM.
