Consider the recovery steps in each of the cases given below：
Case 1：
Shut down the database and perform a backup.
Restore all the data files.
Mount the database.
Recover the database.
Without applying all the redo log files， open the database using the RESETLOGS option.
Back up the database.
Case 2：
Shut down the database and perform a backup.
Restore only the data files of the tablespace where user error damaged the data.
Mount the database.
Recover the database.
Open the database with the RESETLOGS option.
Back up the database.
Case 3：
Shut down the database
Restore the data files
Open the database
Perform recovery to the current point in time.
Which case has the correct steps for an incomplete recovery？（）
A.only case 1
B.only case 2
C.only case 3
D.case 1 and 2
E.case 2 and 3
F.case 1 and 3
G.all cases： case 1， case 2 and case 3
You performed an incomplete recovery on your Oracle Database 10g database using the following command：
SQL> RECOVER DATABASE
2 UNTIL TIME ’20040805：12：10：03’
3 USING BACKUP CONTROLFILE;
In which situation would the above recovery be required？（）
A.A user table was lost at the specified time.
B.A redo log file was lost at the specified time.
C.The backup control file is on a faster disk than the current one.
D.The current control file has a different path compared with the intended time of recovery.
E.The current control file does not match the physical structure of the database at the intended time of recovery.
The current time is 12：00 noon. You want to recover the USERS tablespace from a failure that occurred at 11：50 a.m. You discover that the only member of an unarchived redo log group containing information from 11：40 a.m. onwards is corrupt.
With reference to this scenario， if you are not using Recovery Manager （RMAN）， which recovery method would you use？（）
A.timebased recovery
B.log sequence recovery
C.cancelbased recovery
D.changebased recovery
A.You find that one of the redo log members in each redo log group is lost.
B.You find that a data file that belongs to the USERS tablespace is damaged.
C.You find that a data file that belongs to the SYSTEM tablespace is damaged.
D.You find that the current redo log group is damaged and is not available for recovery.
E.You realized while performing a recovery that an archived redo log file needed for recovery is lost.
You have only two redo log groups and these groups get overwritten several times in a day. Your database operates in NOARCHIVELOG mode and usermanaged consistent backups are performed every Sunday night. On Thursday morning， you find that an important table has been dropped and purged.
With reference to this scenario， up to what point in time can the data be recovered？（）
A.until Thursday morning
B.until last Sunday’s backup
C.until Wednesday evening
D.until that point in time when the database is opened
E.until that point in time when the recovery is performed
F.until that point in time when the table is dropped and purged
A.restore all the data files from last Sunday’s backup， and then perform a timebased recovery
B.restore all the data files from last Sunday’s backup， and then perform a cancelbased recovery
C.restore all the data files from last Sunday’s backup， and then perform a changebased recovery
D.restore only data files that belong to the SYSTEM tablespace from last Sunday’s backup， and then perform a complete recovery
Your database operates in ARCHIVELOG mode. Usermanaged consistent backups are performed every Sunday night.
On Tuesday， client A drops a table at 8：00 a.m. as follows：
SQL> DROP TABLE cust_ord PURGE;
Table dropped.
Client B executes a query at 9：00 a.m. on the same table as follows：
SQL> SELECT * FROM cust_ord;
SELECT * FROM cust_ord
*
ERROR at line 1：
ORA00942： table or view does not exist
Client B needs the dropped table and reports the problem to you. With reference to this scenario， which action should you take？（）
A.retrieve the table by using the flashback feature
B.restore all the data files from last Sunday’s backup， and then perform a timebased recovery
C.restore all the data files from last Sunday’s backup， and then perform a log sequence recovery
D.restore all the data files from last Sunday’s backup， and then perform a cancelbased recovery
E.restore from last Sunday’s backup only data files that belong to the tablespace in which the table was stored， and then perform a complete recovery
You are connected to Recovery Manager （RMAN） without a recovery catalog. There is no copy of the control file available. You want to restore the control file from an autobackup. To retrieve the autobackup，you need the database ID （DBID）.
In which two sources would you find the DBID？ （）
A.the trace file
B.the alert log file
C.an RMAN session log file
D.the server parameter file
E.the formatted name of a control file autobackup
You used the following command in Recovery Manager （RMAN） as part of the recovery process： RESTORE CONTROLFILE FROM AUTOBACKUP;
How does RMAN find the control file autobackup？（）
A.by using the trace file
B.by using the alert log file
C.by using the database ID
D.by using the server parameter file
E.by using the V$CONTROLFILE view
F.by using the autobackup format configuration setting
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
