hi,all

we find a very interesting thing:

we copy the WINDOWS2000 datafile to linux (they have the same byte order)

and , dd a linux datafile header to cover the windows datafile header(the header block is not include in dba_data_files),the block is not seem in database ,it is for OS. ls -l can see ,the datafile size is bigger than dba_data_files for one oracle block.

when we change the OS file header,we can create controlfile and open the database ,and we can query /create table ... etc.

is there someone can discuss it?

Best regards
