You set the recovery window to seven days and the backup optimiza
tion to ON using the CONFIGURE command of Recovery Manager (RMAN). The
most recent backup of the TOOLStablespace to disk was taken on January 3.
The TOOLStablespace is read-only. On February 21, when you execute
a command to back up all the tablespaces to disk, you find that
RMAN backs up the TOOLStablespace also, even though the contents of the
tablespace have not changed after the backup on January 3. Because
there are no changes made to the TOOLStablespace, you decide that the
tablespace should not be backed up by RMAN. What can you do to skip
backing up the TOOLStablespace without changing the current backup
optimization setting?
A. configure a default device for RMAN backups
B. temporarily disable the retention policy for RMAN backups
C. configure automatic channel allocation for RMAN backups
D. use the CONFIGURE command to reconfigure the recovery window to 60 days
Answer: D
