测试服务器上出现这个错误信息。

这个错误是发生在表空间OFFLINE的时候：

这个错误产生的原因是文件头被损坏，其中krhpfh_03-1208错误信息中包含了两部分信息，前一部分krhpfh_03是ORA-600错误的错误号，而后面的1208是导致这个ORA-600错误的错误号，也就是ORA-01208: data file is an old version - not accessing current version。导致这个ORA-600出现的其他常见错误还包括ORA-01202: wrong incarnation of this file - wrong creation time；ORA-01204: file number is string rather than string - wrong file ；ORA-01206: file is not part of this database - wrong database id ；ORA-01209: data file is from before the last RESETLOGS以及ORA-01210: data file header is media corrupt等等。

总的来说就是Oracle发现数据文件的头与控制文件中的不符所致。一般而言，不是由于磁盘损坏了头块，就是由于误操作所致。

当前这个ORA-1208错误比较特别，是BBED修改数据文件的文件头所致，解决方案除了常规的恢复之外，就只有通过BBED修改文件头这个方法了。
