Examine the command used to perform an incremental level-0 backup:
RMAN>BACKUPINCREMENTALLEVELODATABASE ;
To enable block change tracking, after the incremental level 0 backup, you issue the command:
SQL>ALTERDATABASEENABLEBLOCKCHANGETRACKINGUSING
FILE’/mydir/rman_change_track.f’;
To perform an incremental level-1 cumulative backup, you issue the command:
RMAN>BACKUPINCREMENTALLEVEL1CUMULATIVEDATABASE;
Which two statements are true in the preceding situation?
A. The block change tracking data is used only from the next incremental backup.
B. The incremental level 1 backup fails because a block change tracking file Is created after the level 0 backup.
C. The incremental level 1 backup does not use change tracking data for accomplishing the backup.
D. The block change tracking file scans all blocks and creates a bitmap for the blocks backed up in the level 0 backup
E. The block change tracking data is used for the next incremental level 1 backup only after the next level 0 backup.
