Bruno, one way to do it is to edit the user and tablespace directly in the exported binary (which worked for me with versions 8.0.5-8.1.6, never tried
it with any other versions). cf
http://www.galileo.edu/obonilla/writing/oracle/The other way is to change the permissions for the user which unfortunately I am not entirely sure how to do...
something like "revoke unlimited tablespace from username;" and maybe some other stuff. I think there might still be problems with clobs though.
This page talks about it for v7 but I would guess things are similiar for v8.
