A.Backups must be contained in backup sets.

B.Backups can be taken only if the database is in archivelog mode.

C.Backups can be done incrementally.

D.Only consistent backups can be created.

E.Backups must be done incrementally.

A.It removes the AUDSYS schema and the AUDIT_ADMIN and AUDIT_VIEWER roles

B.It increases tablespace size, if required, to meet upgrade requirements.

C.It sets all user tablespaces to "read-only" before starting the upgrade.

D.It empties the RECYCLE BIN.

E.It recompiles all stored PL/SQL code by using utlrp.sql.

F.It performs prerequisite checks to verify if the Oracle database is ready for upgrade.

A.If an RMAN BACKUP VALIDATE command takes roughly the same time as an actual backup, then both read and write I/O are likely bottlenecks.

B.Setting DBWR_IO_SLAVES to a non zero value can improve backup performance when using synchronous I/O.

C.If an RMAN BACKUP VALIDATE command takes noticeably less than an actual backup, then write I/O is a likely bottleneck.

D.If an RMAN BACKUP VALIDATE command takes roughly the same time as an actual backup, then read I/O is a likely bottleneck.

E.Data files with a high value in V$BACKUP_SYNC_IO.DISCRETE_BYTES_PER_SECOND are a potential performance bottleneck when synchronous I/O is used.

F.Setting DBWR_IO_SLAVES to a non zero value can improve backup performance when using asynchronous I/O/

G.Data files with a high value in V$BACKUP_ASYNC_IO.SHORT_WAITS are a potential performance bottleneck when asynchronous I/O is used.
