Your database runs in NOARCHIVELOG mode， and is backed up every night using RMAN scripts. However， last night your assistant DBA performed a manual operating system backup， instead of running the scripts. Today your database crashed and you now want to use the backups from last night. What do you need todo？（）A、You need to perform the restore and recover operations manually, because the backup was made manually. B、First you need to resynchronize the catalog with the control file, and then you can use RMAN to recover the database. C、First you need to add the backup to the catalog using the CATALOG command, and then you can use RMAN to recover the database. D、You can just use RMAN and recover the database, because RMAN automatically updates the catalog with the backup information.

考题
Media recovery can sometimes be stopped by the inability to read past a certain point in the redo stream. This is often referred to as “stuck recovery”. Before Oracle9i， the Database Administrator had few options to deal with stuck recovery. If the corrupt redo could not be recovered from some other source， then all transactions that committed after the corrupt point in the redo steam would be lost. Oracle9i changes that with the Trial Recovery feature. Trial Recover is used to test the application of the redo logs to the database. What are three other characteristics of Trial Recovery（）A、Speeds up subsequent media recover actions.B、Writes any uncorrupted block to disk during the test recovery.C、Can be invoked by adding the TEST option to any RECOVER command.D、Allows the Administrator to determine how many blocks are affected by corruption.E、Marks blocks as corrupt in memory， allowing the test recover to proceed to completion.
考题
In which case would you use the Flashback Database feature to perform a recovery？（）A、to recover a dropped tablespaceB、to recover data from a truncated tableC、to recover a data file that has been shrunkD、to recover a database to the state that existed before the RESETLOGS operation
考题
You are working on an Oracle Database 10g database. For which purposes would you use the Flashback Transaction Query feature？ （）A、 To recover a dropped table.B、 To recover a dropped schema.C、 To recover data from a truncated table.D、 To view changes made by all the transactions during a given period of time.E、 To view changes made by a single transaction during a given period of time.

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、 time-based recoveryB、 log sequence recoveryC、 cancel-based recoveryD、 change-based recovery
