12、artup mount (启动实例并加载数据库，但不打开)SQL alter database archivelog; (更改数据库为归档模式)SQL alter database open; (打开数据库)SQL alter system archive log start; (启用自动归档)SQL exit (退出)2、连接：%rman target=rman/rmanmydb (启动恢复管理器)3、基本设置：RMAN configure default device type to disk; (设置默认的备份设备为磁盘)RMAN configure device type disk p
