RE: How to move a databse from Solaris to Llinux

Maybe they're logically the same, but that doesn't mean they are physically the same. Off the top of my head, I seem to recall that SPARC and x86 architectures have different "endianness", which might be a factor.

Christopher,

i don't consider Solaris and Linux as different OS. IMO they are at least similar if not equal from the DBMS point of view. I don't see any reason why the data files should be different on Solaris, Linux or any other UNIX OS.

I know from DB/2 that the data files are binary compatible on all OS and

I can't believe that's not true for Oracle.

regards

Reinhold
