Which of these represent the main components of Database Resource Manager? (Choose all that apply.)

A. Resource consumer groups
B. Resource plans
C. Resource-plan groups
D. Resource-plan directives
E. All of the above
Answer: A,B,D
The main components are resource consumer groups, resource plans, and resource-plan directives.
There is no such thing as a resource-plan group.
DRM allocates resources among resource consumer groups based on a resource plan. A resource plan
consists of resource-plan directives that specify how resources should be distributed among the groups.
Resource consumer groups are categories（ *ger- “to gather”） to which user sessions can be assigned.
These groups can then be allocated resources through plan directives. Plan directives define resourceallocation rules by assigning resource-allocation methods to specific resource consumer groups. They
connect resource plans to consumer groups and define the resource-allocation method to be used.
