In your database, all the tablespaces are locally managed. You started Recovery Manager (RMAN) using recovery catalog. The following commands are used in the process of recovering the database by using the backup control file:
In what sequence would you use this process to perform the recovery?()
A.7, 2, 3, 1, 4, 6, 5
B.7, 1, 3, 2, 6, 5, 4
C.2, 1, 7, 6, 3, 5, 4
D.2, 7, 3, 5, 1, 6, 4
The loss of the control file forced you to recreate the control file. After recreating it and opening the database, you find that some of the data files are named as MISSINGnnnnn, where nnnnn is a fivedigit number starting with 0.
What could be the possible reason?()
A.These are the data files that are corrupted.
B.There is no SYSAUX tablespace in your database
C.There is a readonly tablespace in your database.
D.These are the data files that cannot be recovered.
A.drop the readonly tablespace and recreate the tablespace after recovery
B.take data files from the readonly tablespace offline before performing a recovery
C.perform a recovery; status of the tablespace in control file will be changed automatically
D.recovery using backup control file is not possible, so restore all the files from the last full database backup, and then open the database
One of the tablespaces is readonly in your database. The loss of all control files forced you to recreate the control file.
Which operation do you need to perform after recreating the control file and opening the database?()
A.drop and recreate the readonly tablespaces
B.rename the readonly data files to their correct file names
C.change the tablespace status from read/write to readonly
D.recreate the readonly tablespace because it is automatically removed
A.restore the tablespace from the backup; there is no need to apply the redo information
B.restore the full database to recover the data up to the point when you performed the backup
C.restore the tablespace from the backup, and then perform a recovery using the backup control file
D.restore the tablespace from the backup, and then recover the tablespace; all the redo information from the point when the tablespace was made read/write is applied
A.ONLINE
B.REVERSE
C.PARALLEL
D.COMPRESS
E.NOLOGGING
F.COMPUTE STATISTICS
You lost the index tablespace in your database. You decided to recreate the index tablespace and the indexes in the tablespace.
What methods can you use to recreate the indexes?()

In your database, online redo log files are multiplexed and one of the members in a group is lost due to media failure.
How would you recover the lost redo log member?()
A.import the database from the last export
B.restore all the members in the group from the last backup
C.drop the lost member from the database, and then add a new member to the group
D.restore all the database files from the backup, and then perform a complete recovery
