问题：
ORA-00600: 内部错误代码, 参数: [kcratr_nab_less_than_odr], [1], [196495], [39399], [39460], [], [], [], [], [], [], []
导致原因：可能是由于服务器宕机，控制文件的缺失，或者在线日志文件在实例恢复时不完整
1、数据库未归档，未备份，没法rman还原
2、数据库可以起到mount状态
3、trace日志 alert_orcl.log日志
根据日志找到 orcl_ora_7268.trc文件日志

解决：重建控制文件
SQL> Show parameter control_files
Keep this location handy.
SQL> oradebug setmypid
SQL> Alter session set tracefile_identifier='controlfilerecreate' ;
SQL> Alter database backup controlfile to trace noresetlogs;
SQL> oradebug tracefile_name ;
此时会生成一个脚本文件
