近期一个客户联系反馈业务系统卡主，无法使用；远程连接查看，发现报错是显示归档空间满了，以为磁盘空间不足。
检查后发现归档空间充足，查看数据库ALERT日志，发现有大量报错：ORA-00354: corrupt redo log block header
ORA-00353: log corruption near block 9443 change 60986471209 time 02/13/2025 16:49:35

ORA-00312: online log 1 thread 1: 'O:\DATABASE\FOOD\LOGFILES\LOG1BFOOD.ORA'
ORA-00312: online log 1 thread 1: 'O:\DATABASE\FOOD\LOGFILES\LOG1AFOOD.ORA'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~~
