单选题In Recovery Manager （RMAN）， you are taking image copies of the data files of your production database and rolling them forward at regular intervals. You attempt to restart your database. After a regular maintenance task， you realize that one of the data files that belongs to the USERS tablespace is damaged and you need to recover the data file by using the image copy. Because a media failure caused the data file to be damaged， you want to place the data file in a different location while resto ing the file. Which option must you consider for this task？（）A using only the RMAN SWITCH command to set the new location for the data fileB placing the database in the MOUNT state for the restore and recovery operationsC using an RMAN RUN block with the SET NEWNAME and then the SWITCH commandD configuring two channels： one for the restore operation and the other for the recovery operation
多选题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（）ASpeeds up subsequent media recover actions.BWrites any uncorrupted block to disk during the test recovery.CCan be invoked by adding the TEST option to any RECOVER command.DAllows the Administrator to determine how many blocks are affected by corruption.EMarks blocks as corrupt in memory， allowing the test recover to proceed to completion.

多选题Which two statements are true about Block Media Recovery （BMR）？（）ABMR increases the Mean Time To Recover （MTTR）.BBMR can only be implemented using Recovery Manager （RMAN）.CThe blocks that need to be recovered are accessible during BMR.DBMR cannot be performed using cumulative incremental backups.EThe datafile must be restored if most of the blocks in the datafile are corrupt.
多选题What are the two advantages of RMAN Block Media Recovery （BMR） over file-level recovery？（）ABMR lowers the mean time to recover （MTTR）.BBMR supports point-in-time recovery of individual data blocks.CBMR enables you to use incremental backups for block recovery.DBMR enables recovery even when the database is not mounted or open.EBMR enables you to use proxy backups to perform block media recovery.FBMR enables increased availability of data during recovery because the data file requires a recovery can remain online.

BTake the individual data file offline (not the whole tablespace), restore and recover the data file from backup with RMAN, then set the data file online again. CWithout setting the individual data file offline, use RMAN with Block Media Recovery to restore and recover only those blocks.
