虽然ORA-600 kkkicreatecgmap:!efn3没有见过但是数据库open过程中kgegpa、kgebse的故障还是遇到不少,大部分可能和undo有一定关系,处理undo问题之后,继续尝试open库,依旧报ORA-03113: end-of-file on communication channel

SQL> alter database Open;
ERROR:

但是后台的alert日志已经改变ORA-600 4193,ORA-600 kkkicreatecgmap:!efn3错误

虽然ORA-600 kkkicreatecgmap:!efn3还在,但是看到了比较熟悉的ORA-600 4193错误,处理undo异常回滚段,数据库open成功,重建undo,尝试导出数据,完成数据恢复任务.

补充说明,对于ORA-00600: internal error code, arguments: [kkkicreatecgmap:!efn3], [1403]网络上没有任何资料,查询了mos发现一个有一点类似的报错信息
Bug 28167557 – bigscn_dbim_tm_def – trc – kkkdchkcriticalobj – ORA-700 [kkkdchkcriticalob (Doc ID 28167557.8)

 ORA-600 kkkicreatecgmap:!group

由于这个是硬件故障恢复出来的数据文件（涉及磁盘坏道，磁盘顺序，磁盘在raid中均衡,raid的cache等因素可能会一起Oracle各种非常规问题）,分析原因意义不大,重点是快速解决问题,不做过多分析
