Exhibit, One of the important tables in the USERStablespace was dropped and purged from the recycle bin at 9:00 a.m. You noticed this at 11:00 a.m. and you want to perform an incomplete recovery to recover the table. Which statement is true?()
A. You must recover all data files to the required system change number (SCN).
B. You must recover all data files, except those that are offline, to the required SCN.
C. You must recover all data files belonging to the USERS tablespace to the required SCN.
D. You cannot recover all data files because segment space management is performed manually for the undo tablespace.
A. A primary key must have been created.
B. A mapping table must have been created.
C. An overflow tablespace must have been specified.
D. The PCTTHRESHOLD option must have been specified.
In your database, all the tablespaces are locally managed. You started Recovery Manager (RMAN) using recovery catalog and restored the control file by using the following command:
RMAN> RESTORE CONTROLFILE;
Which two operations do you need to perform after restoring the control file from backup?()
A. shut down and restart the instance
B. add new tempfiles to the temporary tablespaces after recovery
C. perform a media recovery and open the database with the RESETLOGS option
D. perform a media recovery and bring the database to NOARCHIVELOG mode
Your database operates in ARCHIVELOGmode. The redo log files are not multiplexed and one of the online redo logs is missing. The missing redo log sequence, 230, is not archived and it contained information from 10:35 a.m. onwards. The current time is 11:00 a.m. Because of a disk crash, you executed the following command to perform an incomplete recovery:
RMAN> RUN {
2> SET UNTIL SEQUENCE 230 THREAD 1;
3> ALTER DATABASE MOUNT;
4> RESTORE DATABASE;
5> RECOVER DATABASE;
6> ALTER DATABASE OPEN RESETLOGS;
7> };
With reference to this scenario, which statement is true?()
A. RMAN recovers up to log sequence 230, but not including 230.
B. RMAN returns an error because the log sequence number mentioned in the command should be 229.
C. RMAN returns an error because the log sequence number mentioned in the command may never be missing.
D. RMAN recovers up to and including log sequence 229 but then returns an error because log sequence 230 is missing.
A. a list of files that require a backup within three days
B. a list of files that have not been backed up for three days
C. a list of files that RMAN recommends be backed up only once in every three days, based on low volatility
D. a list of files for which a backup has already been performed and may need a backup after three days
