数据库意外宕机，归档开了，但是归档文件损坏，redo损坏，在强行拉起来之后UNDO报错，设置_corrupted_rollback_segments 跳过不一致的ＵＮＤＯ，重建UNOD表空间，接着报错：SMON encountered 100 out of maximum 100 non-fatal internal errors. 然后数据库自动宕机，报错处理如下：
１ORA-00600: internal error code,arguments: [13013],[5001],[458],[4197442],[6],[3],[],[]

果断报错

ORA-00600: internal error code,arguments: [kewrose_1],[600]由这个错误产生，mmon进程有关，非关键进程，可以杀掉重启，
