You are managing the APPPROD database as a DBA. You plan to duplicate this database in the same system with the name DUPDB.
You issued the following RMAN commands to create a duplicate database:
RMAN> CONNECT target sys/[email protected]
‘/oracle/oradata/prod/’, ‘/scratch/oracle/oradata/dupdb/’ SET SGA_MAX_SIZE = ‘300M’ SET SGA_TARGET = ‘250M’ SET LOG_FILE_NAME_CONVERT ‘/oracle/oradata/prod/redo/’,
Which three are the prerequisites for the successful execution of the above command? (Choose three.)

A.    The source database should be open.
B.    The target database should be in ARCHIVELOG mode if it is open.
C.    RMAN should be connected to both the instances as SYSDBA.

D.    The database writes the before image of an entire block to the redo stream before modifying. block tor
the first time.

Answer: CD
Making User-Managed Backups of Online Read/Write Tablespaces
You must put a read/write tablespace in backup mode to make user-managed data file backups when the tablespace is online and the database is open. TheALTER TABLESPACE … BEGIN BACKUP statement places a tablespace in backup mode. In backup mode, the database copies whole changed data blocks into the redo stream. After you take the tablespace out of backup mode with the ALTER TABLESPACE … END BACKUP or ALTER DATABASE END BACKUP statement, the database advances the data file checkpoint SCN to the current database checkpoint SCN.
When restoring a data file backed up in this way, the database asks for the appropriate set of redo log files to apply if recovery is needed. The redo logs contain all changes required to recover the data files and make them consistent.

Which statement is true regarding the retention policy for the incidents accumulated in the Automatic Diagnostic Repository (ADR)?
