--查看警报日志，具体错误看日志里写的trc文件。服务器异常断电，导致LGWR写联机日志文件时报错，下次重启数据库时，需要实例级恢复，而又无法从联机日志文件中获取到redo信息，因为上次断电，写日志报错。

--解决方案
从这里可以看到出现了ORA-600[4194]/[4193]，第一感觉就是undo出现问题。
4193：表示undo和redo不一致（Arg [a] Undo record seq number，Arg [b] Redo record seq number ）；
4194：表示也是undo和redo不一致（Arg [a] Maximum Undo record number in Undo block，Arg [b] Undo record number from Redo block）
所以出现4193错误，解决方法跟4194一样。
