Which two statements are true about Resource Manager plans for individual pluggable databases (PDB plans) in a multitenant container database (CDB)?
A. If no PDB plan is enabled for a pluggable database, all sessions for that PDB are treated to an equal share of resources.
B. To enable a resource plan for a PDB, a CDB resource plan must be created and enabled.
C. If a PDB plan is enabled for a pluggable database, Resource Manager uses the resource allocation at the PDB level and ignores the limits set at the CDB level.
D. If no PDB plan is enabled for a pluggable database, the PDB uses the CDB plan.
E. If a PDB plan is enabled for a pluggable database, resources are allocated to consumer groups based on the shares provided to the PDB in the CDB plan and the shares provided to the consumer groups in the PDB plan.
Correct Answer: AE
Explanation/Reference:
Explanation:
A: A CDB resource plan determines the amount of resources allocated to each PDB. A PDB resource plan determines how the resources allocated to a specific
PDB are allocated to consumer groups within that PDB.
Resource Manager allocates the resources in two steps:
1.It allocates a portion of the system’s resources to each PDB.
2.In a specific PDB, it allocates a portion of system resources obtained in Step 1 to each session connected to the PDB.
E: A PDB resource plan allocates resource among the consumer groups within a PDB.
