这里可以得出几个结论：
1)版本平台信息
2)通过下面信息都是知道,data_object_id=294044的对象出现异常(seg.obj=-2)

OBJD MISMATCH typ=6, seg.obj=-2, diskobj=294051, dsflg=0, dsobj=294044, tid=294044, cls=1

Block header dump:  0x0435c094
 Object id on Block? Y
 seg/obj: 0x47ca3  csc: 0xb2d.2b4f8874  itc: 2  flg: E  typ: 2 - INDEX
     brn: 0  bdba: 0x435c091 ver: 0x01 opc: 0
     inc: 0  exflg: 0

3)结合dba_objects视图查询出来是xifenfei_index 索引出现异常

问题原因猜测
因为没有找到权威解释，对于这里在online表空间的时候出现ORA-00600[kcbz_check_objd_typ]错误,个人的猜测可能是在online的时候，验证数据字典中关于该表空间中对象的相关记录和该表空间总的存储数据比较，然后发现不匹配，所以出现了该错误。

处理方法
虽然该表空间离线，但是我们可以使用drop操作直接删除数据字典中index的记录，然后再online表空间，这样可以绕过数据字典和表空间中的存储比较。当表空间online成功后，然后再创建index
