数据库记录文件大小

比较明显数据文件头记录文件大小为12800*8192+8192(block 0)=104865792,而文件系统中显示的文件大小为104865793,不是8192的整数倍。因此出现相关错误DBV-00600: 致命错误 – [21] [5] [0] [0] 或者 DBV-00113(通过mos确认Bug 18232647 – DBVerify reports DBV-600 [21] [5] [0] [0] when datafile size is beyond expected – produce a more meaningful error (Doc ID 18232647.8))
