1Z0-083 Exam Question 222

Which two are true about instance recovery?

A.It is performed automatically while the database remains in mount state. Then the database is opened.

B.Setting fast_start_mttr_target to a lower value reduces instance recovery time by causing dirty buffers to be written to disk more frequently, thereby reducing the number of I/Os needed during instance recovery.

C.It is not possible if an archived log is missing.

D.It is performed automatically after the database is opened; however, blocks requiring recovery are not available until they are recovered.

E.It is performed by the Recovery Writer (rvwr) background process.

F.Setting fast_start_mttr_target to a higher value reduces instance recovery time by causing the log writer to write more frequently, thereby reducing the number of I/Os needed during instance recovery.

1Z0-083 Exam Question 223

Which two are true about gathering optimizer statistics? (Choose two.)

B.Executing DBMS_STATS.GATHER_DATABASE_STATS while connected to a PDB opened in read/write mode gathers object statistics for that PDB.

C.Executing DBMS_STATS.GATHER_DATABASE_STATS while connected to CDB$ROOT gathers object statistics only in CDB$ROOT.

D.System statistics can be gathered only while connected to CDB$ROOT.

E.Executing DBMS_STATS.GATHER_DATABASE_STATS while connected to CDB$ROOT gathers object statistics in all open pluggable databases (PDBs)
