Oracle OCP 1Z0 053 Q505(RMAN DATAFILE BACKUP COPIES)

505.You configured the default backup device type as disk for RMAN backups. In your database, because
of business requirements, you have to take a simultaneous duplicate backup of the data files when the
RMAN BACKUP command is used.
What must you set using the RMAN CONFIGURE command to achieve this?
A. MAXSETSIZE TO 2;
B. DEVICE TYPE DISK PARALLELISM 2;
C. RETENTION POLICY TO REDUNDANCY 2;
D. DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 2;
Answer: D

題意是要複製資料檔案備份

RMAN> configure datafile backup copies for device type disk to 2;


新的 RMAN 配置引數:
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 2;
已成功儲存新的 RMAN 配置引數

RMAN> backup datafile 1;
