– 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。

– 新建个临时表空间，修改默认 spflie 里的 undo_tablespace 参数。记得手动修改下 pflie 的默认表空间参数。
