This document summarizes Oracle Resource Manager, which allows administrators to prioritize and limit resource usage for different database users or applications. It discusses concepts like resource consumer groups, resource plans, and resource plan directives. It also provides examples of creating simple and complex resource plans using DBMS_RESOURCE_MANAGER package and managing resource plans through Oracle Enterprise Manager and command line interfaces. Finally, it mentions views for monitoring resource usage and privileges needed to manage resource consumer groups.

9. NotesThe currently active resource plan does not enforce allocation limits until CPU usage is at 100%.When limits are enforced, unused allocation by any consumer group can be used by other consumer groupsIt is possible for a subplan or consumer group to have more than one parent.No more than 31 resource consumer groups in any active planAt most, a plan can have 31childrenPlans and resource consumer groups cannot have the same name.
