Customization considerations

IBM Z Workload Scheduler is designed as a general-purpose workload automation subsystem. As such, it might not meet all the requirements for your specific installation. IBM® allows installations to implement installation exits and provides many callable services that can be used to supplement IBM Z Workload Scheduler processing.

Carefully examine any customization that your site has installed. Determine whether the function is now provided in the product or if you need to modify the logic based on changes made to IBM Z Workload Scheduler.

When new functions are added to IBM Z Workload Scheduler, installation exits and macros used within installation exits can change. New installation exits or macros might also be introduced in an IBM Z Workload Scheduler release. If a release provides a new installation exit, determine if your installation needs to implement the exit. A release can change an existing exit by modifying:
  • What the installation exit expects on entry.
  • Return codes IBM Z Workload Scheduler expects when the exit returns control to IBM Z Workload Scheduler.
  • The function that the installation exit performs.
  • The processing that is performed before or after the exit.
