ORA-00314 ORA-00312 – 专业Oracle数据库恢复，或许是您恢复数据的最后机会@phone:17813235971

最近一个运行在win平台的rac,由于断电之后,集群两个节点均无法正常启动,客户进行了一系列尝试,结果到了ora-600 kclchkblk_4错误无法继续.
通过对数据库日志分析,回溯了故障大概的原因,启动的时候报错为:

看到这两个报错信息得出两个结论：
1）比较明显节点1需要thead 2的 group 11 sequence为147717,但是实际group 11文件的sequence为147541；而节点2启动需要thread 1的group 1 sequence为67782，但是实际中group 1文件的sequnece为60818,这两个都相差比较多,属于非正常的情况,很可能是文件本身有问题
2）这是一套win的rac架构,理论上redo应该在共享文件系统（一般是asm中)，而这个第一感觉很可能是本地文件系统中
客户当时恢复之时查询信息截图

查看了两个节点的最后redo切换信息

--节点1
Sat Aug 02 10:49:31 2025
Thread 1 advanced to log sequence 67782 (LGWR switch)
  Current log# 1 seq# 67782 mem# 0: D:\REDOLOG\REDO01.LOG

--节点2（redo每组2G,节点2长时间没跑业务,之时做数据库导出操作,所以切换时间比较久远）
Sat Jul 26 16:56:42 2025
Thread 2 advanced to log sequence 147717 (LGWR switch)
  Current log# 11 seq# 147717 mem# 0: D:\REDOLOG\REDO011.LOG

并查看两个机器d:/redolog信息(客户自行resetlogs之后的,非第一现场,但是可以确认两个节点各自有一份redo文件

本来这个是一个比较小的故障,只要把节点2的thread 1的redo拷贝到到节点1或者节点1的thread 2的redo拷贝到节点2,然后正常open库即可,现场恢复对rac不太熟悉,直接按照互联网上检索的处理方法,加上_allow_resetlogs_corruption然后强制拉库,结果不太幸运,拉库失败报ORA-600 kclchkblk_4错误

运气不错,直接打开数据库成功,然后逻辑导出数据,完成此处恢复.这个让我想起来了一些类似案例:
Oracle 23ai rm redo*.log恢复
 清空redo,导致ORA-27048: skgfifi: file header information is invalid
由于默认情况下oracle的redo文件扩展名是.log,然后被当做是不重要文件从而被清理导致数据库故障,在oracle服务器上清理数据之前建议查询v$datafile,v$logfile,v$tempfile,v$controlfile来确认是否是数据库文件
