Defining a ruleset


A ruleset makes the definition of workload load designer on to system. It is a collection of settings that together makes up the workload management environment. A ruleset includes all the workloads expected to be used when the ruleset is active, as well as all throttles, filters, and exceptions.

A ruleset contains:

  • The state definition
  • Filters
  • Throttles
  • Exceptions
  • Workload definitions
  • Virtual partitions

It also includes virtual partition settings for the workloads that make up the ruleset, and the ruleset captures any automated changes to settings that have been defined, as well as the events that trigger such changes.
