考题
Redo log files are multiplexed in your database. The disk in which you have one of the redo log members is highly fragmented. In the process of defragmentation you lose the redo log member， which is not a member of the current group. How would you recover from the loss of the redo log member？（）A、SMON would automatically restore the lost file.B、You would need to restore the whole database from the last backup.C、You would need to restore the file from the last full database backup.D、You would need to use flashback technology to restore the lost redo log member.E、You would need to use Recovery Manager （RMAN） to restore the lost redo log member.F、You would need to restore the missing log file by copying one of the remaining files from the same group.
考题
You performed an incremental level 0 backup of a database: RMAN BACKUP INCREMENTAL LEVEL 0 DATABASE; To enable block change tracking after the incremental level 0 backup, you issued this command: SQL ALTER DATABASE ENABLE BLOCK CHANGE TRACKING USING FILE ‘ /mydir/rman_change_track.f’; To perform an incremental level 1 cumulative backup, you issued this command: RMAN BACKUP INCREMENTAL LEVEL 1 CUMULATIVE DATABASE; Which three statements are true?（）A、Backup change tracking will sometimes reduce I/O performed during cumulative incremental backups.B、The change tracking file must always be backed up when you perform a full database backup.C、Block change tracking will always reduce I/O performed during cumulative incremental backups.D、More than one database block may be read by an incremental backup for a change made to a single block.E、The incremental level 1 backup that immediately follows the enabling of block change tracking will not read the change tracking file to discover changed blocks.
