有客户由于机房要停电,正常关闭两个节点数据库,通过数据库alert日志均可看到类似如下记录,证明数据库确实是正常shutdown immediate


然后关闭存储,启动存储之后发现数据库无法正常启动(数据scn不一致).相关信息如下：

提示ctl不存在,通过处理之后报ORA-600 2131错误

基于上述情况,很可能是由于存储重启之后,cache或者某些数据没有写入到数据文件和redo中,数据库重启之后redo不是最新的[ORA-00322错误可以证明,],数据文件也需要进行恢复(不是数据库正常关闭之后该有的情况),而且redo和数据文件还不一致[ORA-00600 6102可以证明],对于类似这样的情况,只能尝试强制打开数据库,报ORA-600 2663

该错误比较常见,参考:ORA-600 2663，也可以利用我的Patch_SCN小工具快速解决,后续数据库报ORA-03113错
