268.You are using Recovery Manager (RMAN) for backup and recovery operations with a recovery
catalog. You have been taken database backups every evening. On November 15, 2007, at 11:30 AM,
you were informed that the USER_DATA tablespace was accidentally dropped.
On investigation, you found that the tablespace existed until 11:00 AM, and important transactions were
done after that.
So you decided to perform incomplete recovery until 11:00 AM. All the archive logs needed to perform
recovery are intact. In NOMOUNT state you restored the control file that has information about the
USER_DATA tablespace from the latest backup. Then you mounted the database.
Identify the next set of commands that are required to accomplish the task?
A.RMAN> run
{
SET UNTIL TIME 'Nov 15 2007 11:00:00';
RESTORE DATABASE;
RECOVER DATABASE;
}
B.RMAN> run
{
SET UNTIL TIME 'Nov 15 2007 11:00:00';
RESTORE DATABASE;
RECOVER DATABASE USING BACKUP CONTROLFILE;
}
C.RMAN> run
{
RESTORE DATABASE;
RECOVER DATABASE UNTIL TIME 'Nov 15 2007 11:00:00';
}
D.RMAN> run
