Thank you very much for answering.

+ I create a database on my NT server.

+ I create the tablespaces with THE SAME NAME as the Unix Originals.

create tablespace SAMENAME datafile 'd:\foo\foo.dbf' size
10m autoextend on next 5m maxsize 50m;

+ And d:\foo\foo.dbf ? Must it be the same as Unix?

+ And the size? Must it be similar?

Thank you very much...
