A. If no PDB plan is enabled for a pluggable database, then all sessions for that PDB are treated to an equal degree of the resource share of that pdb.
B. In a PDB plan, subplans may be used with up to eight consumer groups.
C. If a PDB plan is enabled for a pluggable database, then resources are allocated to consumer groups across all PDBs in the cdb.
D. If no PDB plan is enabled for a pluggable database, then the PDB share in the CDB plan is dynamically calculated.
E. If a PDB plan is enabled for a pluggable database, then 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.
第7题:
Your multitenant container database, CDB1, is running in ARCHIVELOG mode and has two pluggable databases, HR_PDB and ACCOUNTS_PDB. An RMAN backup exists for the database.You issue the command to open ACCOUNTS_PDB and find that the USERDATA.DBF data file for the default permanent tablespace USERDATA belonging to ACCOUNTS_PDB is corrupted.What should you do before executing the commands to restore and recover the data file in ACCOUNTS_PDB?()
A. Place CDB1 in the mount stage and then the USERDATA tablespace offline in ACCOUNTS_PDb.
B. Place CDB1 in the mount stage and issue the ALTER PLUGGABLE DATABASE accounts_pdb CLOSE IMMEDIATE command.
C. Issue the ALTER PLUGGABLE DATABASE accounts_pdb RESTRICTED command.
D. Take the USERDATA tablespace offline in ACCOUNTS_PDb.
