根据经验这种错误一般是由于强制打开库失败导致,回溯oracle alert日志发现类似操作

由于无法正常recover 操作，数据库需要强制打开,考虑到之前该库open的过程有ORA-600 2662错误,这次在打开之前使用Patch_SCN调整SCN(关于Patch_SCN文章:Patch_SCN for Linux 功能完善
[oracle@xifenfei.com tmp]$ ./Patch_SCN 249756 0x205D38954E
Successfully obtained address automatically: 0x6001ae70
Original Oracle SCN at Address 0x6001ae70: 0x0
Are you sure you want to modify Oracle SCN? (yes/no): yes
New SCN at Address 0x6001ae70: 0x205d38954e
Oracle SCN successfully modified.
然后数据库顺利打开
在expdp导出数据过程中遇到了硬件错误
为了安全性采用库只读情况下exp进行导出,运气不错所有数据顺利导出,完成本次数据恢复任务
