第6题:
If you find errors in the view V$DATABASE_BLOCK_CORRUPTION with a status of MEDIA_CORRUPT, what RMAN command would you run to correct the problem?()
第7题:
Reduced MTTR.
Datafiles remain offline while corrupt blocks are repaired.
Datafiles remain online while corrupt blocks are repaired.
A and C
第8题:
BMR increases the Mean Time To Recover (MTTR).
BMR can only be implemented using Recovery Manager (RMAN).
The blocks that need to be recovered are accessible during BMR.
BMR cannot be performed using cumulative incremental backups.
The datafile must be restored if most of the blocks in the datafile are corrupt.
第9题:
It detects corrupt blocks.
It performs only offline database backups.
It omits empty blocks during backups.
It performs tablespace point-in-time recovery (TSPITR).
第10题:
Rebuild the index using the online option.
Take the individual data file offline (not the whole tablespace), restore and recover the data file from backup with RMAN, then set the data file online again.
Without setting the individual data file offline, use RMAN with Block Media Recovery to restore and recover only those blocks.
Take the individual data file (not the whole tablespace) offline, use RMAN with Block Media Recovery to restore and recover only those blocks, then set the data file online again.
第11题:
BMR lowers the mean time to recover (MTTR).
BMR supports point-in-time recovery of individual data blocks.
BMR enables you to use incremental backups for block recovery.
BMR enables recovery even when the database is not mounted or open.
BMR enables you to use proxy backups to perform block media recovery.
BMR enables increased availability of data during recovery because the data file requires a recovery can remain online.
第12题:
V$BACKUP_CORRUPTION
V$COPY_CORRUPTION
V$DATABASE_BLOCK_CORRUPTION
RC_BACKUP_CORRUPTION
第13题:
Which of the following statement is incorrect regarding RMAN?()
第14题:
You are performing a block media recovery on the tools01.dbf data file in the SALES database using RMAN. Which two statements are correct in this scenario?()
第15题:
Which two statements are true about Block Media Recovery (BMR)?()
第16题:
What are the two advantages of RMAN Block Media Recovery (BMR) over file-level recovery?()
第17题:
Users complain SQL statements using a particular index fail. Using DBVERIFY, you find that two separate blocks in the index have become corrupt. The database data files for user data and index are very large. What is the least disruptive recover strategy available in Oracle9i?()
第18题:
Create a backup of the database and recover all corrupted blocks found in the backup.
Run a backup validation and list all the logically corrupt blocks as well as physically corrupt blocks in the database.
Run a backup validation to populate V$COPY_CORRUPTION view, and then list any corrupt blocks recorded in the view.
Run a backup validation to populate V$DATABASE_BLOCK_CORRUPTION view, and then repair any corrupt blocks recorded in the view.
Run a backup validation, repair any corrupt blocks found during the validation process, and then update V$DATABASE_BLOCK_CORRUPTION view to indicate which corrupt blocks have been repaired.
第19题:
All datafiles of a database
All datafiles, archive logs, and control files
All datafiles and control files
All the used blocks in a datafile
第20题:
Block Media Recovery must be used with RMAN.
You must perform complete recovery of individual blocks.
You must have a full RMAN backup, not an incremental backup.
You must use the DBVERIFY utility before using the Block Media Recovery feature.
第21题:
create a backup of the database and recover all corrupted blocks found in the backup
run a backup validation and list all the logically corrupt blocks as well as physically corrupt blocks in the database
run a backup validation to populate V$COPY_CORRUPTION view, and then list any corrupt blocks recorded in the view
run a backup validation to populate V$DATABASE_BLOCK_CORRUPTION view, and then repair any corrupt blocks recorded in the view
run a backup validation, repair any corrupt blocks found during the validation process, and then update V$DATABASE_BLOCK_CORRUPTION view to indicate which corrupt blocks have been repaired
第22题:
The code will run a backup validation to populate the V$BACKUP_CORRUPTION view and repair corrupt blocks, if any, recorded in the view.
The code will run a backup validate to populate the V$COPY_CORRUPTION view and then repair any corrupt blocks recorded in the view.
The code will runs a backup validate to populate the V$DATABASE_BLOCK_CORRUPTION view and then repair corrupt blocks, if any, recorded in the view.
The code will run a backup validate to populate the RC_BACKUP_CORRUPTION view and then repair corrupt blocks, if any, recorded in the view.
第23题:
recover lost blocks
recover corrupt blocks
recover media corrupt blocks from list
recover corrupt blocks from list
recover corruption list
第24题:
You must ensure that the SALES database is mounted or open.
You must restore a backup control file to perform a block media recovery.
You must take the tools01.dbf data file offline before you start a block media recovery.
You must put the database in NOARCHIVELOG mode to perform a block media recovery.
You can perform only a complete media recovery of individual blocks; point-in-time recovery of individual data blocks is not supported.
