Superclasses and subclasses
AIX WLM aggregates processes into superclasses and subclasses of those superclasses. There can be up to 27 user-defined superclasses, and up to 10 subclasses within each. WLM enables a delegated authority to configure the subclasses within each superclass.
WLM can automatically assign processes to superclasses and subclasses using rules examining the owing user ID, binary executable, and other parameters. Alternatively, the wmlassign command manually assigns processes to particular classes. Given the appropriate authorization, a startup script can assign its own process to the appropriate class. A process may be assigned to only a superclass, in which case it is automatically assigned to the "default" subclass; or it might be assigned to a specific subclass within the superclasss. Example 8-1 illustrates class assignment.
Example 8-1 Assigning classes
WebSphere assigned for /usr/WebSphere/AppServer/java/bin/java WebSphere.Mortgages subclass manually assigned WebSphere.AccountOpening subclass manually assignedWLM collects processor, memory, and disk I/O bandwidth use by class. It could assign processes running the WebSphere Java binary executable to a WebSphere supergroup. That would allow for up to 10 subgroups, each a different application.
