oracle数据库启动时，scn检查原则及解决办法：

CF checkpoint > Datafile checkpoint SCN Media recovery required Most likely a datafile has been restored from backup Recovery is now required
CF checkpoint = Datafile checkpoint SCN Start up normally None
Database in mount mode,instance thread status = OPEN Crash recovery required None
