Element Description
Resource Consumer Group The group of users that share the same
resource requirements.
Resource Plan This is a plan that defines through directives
how the instance resources will be allocated.
Resource Allocation Method This is the policy or method used by Resource
Manager to allocate resources. This is used by
resource consumer groups and plans.
Resource Plan Directive Directives are defined inside a Resource Plan
and they define how resources are allocated to
the individual resource consumer groups.
Resource Consumer Group Mapping This defines the mapping between users and
resources consumer groups.

At a given time a Resource Plan directs how resources are allocated.
