Consider the following guidelines for creating workload throttles:

  • Set workload throttles limits first and then introduce system-level throttle limits later, if needed.
  • Be cautious in applying throttles to Tactical workloads because they have a high priority and usually need to run immediately.
  • Define workload throttle limits for both Base and system busy states.
  • Favor production work by applying throttles to development work.
  • Favor ad hoc and reporting work over administration requests.
  • Throttle Low and Medium Timeshare workloads to avoid a shortage of AMP worker tasks.

When creating system throttles, explicitly exclude utilities. To do this, you can use the application name as a request source criterion.
