心里蓦然一惊，以为REDO损坏，那可是大麻烦了，这个小系统是个很古老的ORACLE 10G，没有有效备份的；

仔细一想，REDO损坏但是数据库系统没宕机，仔细分析日志，发现CURRENT状态的日志正常，需要切换日志，而此时发现需要重用的REDOLOG损坏（也未归档）所以报错，相当于没有可用的REDO LOG了；

这样解决办法就多了，比如CLEAR命令重置REDO LOG；或者再增加一组（删除损坏的一组）等。由于其他人处理已经重启数据库，停止在MOUNT状态了，这里使用了CLEAR方法临时解决了。

后续此系统还出现过类似问题，数据库运行在虚拟机环境的，综合考虑建议新建服务器做了迁移，目前运行稳定，算是解决了~~

解决步骤与命令：
