Your database operates in ARCHIVELOG mode and all the tablespaces are online. Due to a user error， you decided to perform an incomplete recovery. Which two tasks would you be required to perform in the recovery process？ （）
On Tuesday， a junior DBA dropped an important application user account， whose schema has important tables. You are asked to recover all the objects in the schema. On investigation， you find that the user account was dropped at 11：00 a.m. and Sunday’s backup is the most recent backup. Which flashback feature would you use？（）
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？（）
You lost the index tablespace in your database. You are not able to use tablespace pointintime recovery on the index tablespace. What could be the reason for this？（）
You disabled the Flashback Database feature by using the following command： SQL> ALTER DATABASE FLASHBACK OFF; What would be the effect of this command on the existing flashback logs？（）
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？（）
Your database operates in ARCHIVELOG mode and usermanaged consistent backups are performed every Sunday night. On Tuesday， at 9：00 a.m. the current log sequence number was 369. Also， on Tuesday you lost the data file belonging to the SYSTEM tablespace and an archivelog file （sequence number 356） that contained redo entries between 8：00 a.m. and 8：30 a.m. With reference to this scenario， what would you do to recover the database？（）
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？ （）
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？（）
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？（）
