Classification rules are the rules workload management uses to associate a performance goal and/or a resource group with work by associating incoming work with a service class. Optionally, classification rules can also associate incoming work with a report class, similar to a report performance group.
The classification rules for a subsystem are specified in terms of transaction qualifiers such as job name or transaction class. These qualifiers identify groups of transactions that should have the same performance goals and importance. The attributes of incoming work are compared to these qualifiers and, if there is a match, the rule is used to assign a service class to the work. A subsystem can also have a default class for work that does not match any of the rules.
Figure 1 shows how work classification rules associate a service class, and optionally a report class with incoming work.
Optionally, classification rules can assign incoming work to a report class. You get reporting information in terms of workloads, service classes, and report classes. Use report classes for obtaining data on a subset of work within a service class, or for rolling up data across workloads.
