RMAN 配置參數爲:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 3 DAYS;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'd:\backup\control_%F';
CONFIGURE DEVICE TYPE DISK PARALLELISM 2 BACKUP TYPE TO BACKUPSET;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1;
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1;
CONFIGURE CHANNEL 1 DEVICE TYPE DISK FORMAT 'D:\BACKUP\BACKUP_%U';
CONFIGURE CHANNEL 2 DEVICE TYPE DISK FORMAT 'D:\BACKUP\BACKUP_%U';
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'D:\ORACLE\PRODUCT\10.2.0\DB_1\DATABASE\SNCFBACK.ORA'; # default
介紹一下參數
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 3 DAYS; --備份策略，保留3天的備份
CONFIGURE RETENTION POLICY TO REDUNDANCY 7; --備份策略，保留7個備份
這兩個備份策略只能兩個取一，不能共存。
CONFIGURE BACKUP OPTIMIZATION ON; --備份優化打開，不知道oracle爲什麼不默認打開
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default --備份設備設備disk爲磁盤,sbt爲磁帶
CONFIGURE CONTROLFILE AUTOBACKUP ON; --控制文件備份是否自動備份，意思是說備份數據庫的同時是否自動備份控制文件
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'd:\backup\control_%F'; --控制文件備份的目錄和格式
CONFIGURE DEVICE TYPE DISK PARALLELISM 2 BACKUP TYPE TO BACKUPSET; --備份的並行度和備份壓縮
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; --備份的數據文件 有幾個副本
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; --備份的歸檔日誌 有幾個副本
CONFIGURE CHANNEL 1 DEVICE TYPE DISK FORMAT 'D:\BACKUP\BACKUP_%U';
CONFIGURE CHANNEL 2 DEVICE TYPE DISK FORMAT 'D:\BACKUP\BACKUP_%U'; --分配通道，通道的備份目錄
CONFIGURE MAXSETSIZE TO UNLIMITED; # default --備份集的大小，這個還是UNLIMITED爲好，因爲我們總是無法估計備份集的大小
CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'D:\ORACLE\PRODUCT\10.2.0\DB_1\DATABASE\SNCFBACK.ORA'; # default --備份文件的鏡像
