Which two are true about instance recovery? (Choose two.)

Options:

A.

It is not possible if an archived log is missing.

B.

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

C.

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.

D.

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

E.

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

F.

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

Questions # 78:

Choose two. You are managing this configuration: 1. CDB1 is a container database. 2. PDB1 and PDB2 are two pluggable databases in CDB1. 3. USER1.EMP is a table in PDB1 and USER2.DEPT is a table in PDB2 . CDB1 user SYS executes these commands after connecting successfully to PDB2: SQL> ALTER SESSION SET CONTAINER=pdb1; Session altered. SQL> INSERT INTO user1.emp VALUES (100, 'Alan' ,1) ; 1 row created. SQL> INSERT INTO user1.emp VALUES (101, 'Ben' ,1) ; 1 row created. SQL> ALTER SESSION SET CONTAINER=pdb2; Session altered.
