using target database control file instead of recovery catalog
rman configuration parameters for database with db_unique_name pu are:
configure retention policy to recovery window of 7 days; ----備份過期設定到7天
configure backup optimization off; # default
configure default device type to disk; # default
configure controlfile autobackup off; -----不開啟，自己寫備份指令碼
configure controlfile autobackup format for device type disk to '/u01/rmanbackup/bak_%f'; -----備份存放的路徑
configure device type disk parallelism 1 backup type to backupset; # default
configure datafile backup copies for device type disk to 1; # default
