第17题:
You are managing an Oracle Database 11g database. You want to take a backup on tape drives of the USERS tablespace that has a single data file of 900 MB. You have tape drives of 300 MB each. To accomplish the backup, you issued the following RMAN command: RMAN>BACKUP SECTION SIZE 300M TABLESPACE users; What configuration should be effected to accomplish faster and optimized backups by using the above command?()
第18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?()
