1. 异常介绍
ORA-01113: file 28 needs media recovery
ORA-01110: data file 28: '/<path>/<filename>.dbf'
在Oracle数据库启动过程中如果遇到ORA-01113/ORA-01110报错，造成数据库无法正常启动，日志文件可用时使用日志文件进行正常恢复，当日志文件损坏或所需日志被删除无法通过常规手段恢复时，通常使用bbed工具刷新数据文件头scn，使所有数据文件scn一致，成功启动数据库，使用bbed工具修复存在以下问题，
1、需要bbed工具非常熟悉
2、需要对Oracle数据块结构非常熟悉
3、需要对字节序熟悉
4、需要非常细心，逐字节逐文件修改，耗时且容易出错，
基于以上原因，本文使用工具一键刷新Oracle数据文件scn，操作过程如下所示，
