Your database runs in NOARCHIVELOG mode, and is backed up every night using RMAN scripts. However, last night your assistant DBA performed a manual operating system backup, instead of running the scripts. Today your database crashed and you now want to use the backups from last night. What do you need todo?()A、You need to perform the restore and recover operations manually, because the backup was made manually. B、First you need to resynchronize the catalog with the control file, and then you can use RMAN to recover the database.

单选题You set the recovery window to seven days and the backup optimization 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 TOOLS tablespace 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 backupsB
temporarily disable the retention policy for RMAN backupsC
configure automatic channel allocation for RMAN backupsD
use the CONFIGURE command to reconfigure the recovery window to 60 days
