客户尝试重建ctl进行恢复,结果由于分析不正确,导致在重建ctl的时候,遗漏了3个数据文件,并且在屏蔽一致性的情况下,强制resetlogs操作,结果数据库没有被正常打开,而是报ORA-600 2662错误

操作到这里,后续问题就比较麻烦了,因为在asm磁盘组中数据文件重建ctl的时候遗漏3个并且还被resetlogs操作过,导致这三个文件的resetlogs scn和其他数据文件不一致,对于这个问题,解决办法通过Oracle Recovery Tools工具或者bbed修改相关resetlogs scn,然后重建ctl
SQL> @rectl.sql Control file created. SQL> RECOVER DATABASE; Media recovery complete
然后解决之前数据库启动报ORA-600 2662问题,通过修改数据库scn进行解决,可以使用Patch_SCN工具进行快速解决,然后open数据库成功
SQL> ALTER DATABASE OPEN; Database altered.
但是查看alert日志数据库报大量ORA-600 4194、ORA-01595和Exception [type: SIGSEGV, Address not mapped to object] [ADDR:0xC21D511] [PC:0x97F4EFA, kgegpa()+40]之类错误

从报错分析是由于undo异常导致,处理异常undo回滚段之后,数据库open正常,安排逻辑迁移数据,完成本次恢复
