Answer 1

What happens if you move the view to the remote db?
and create a synonym for the view on the local?it doesn't work !
>
alternatively,
what happens if you modify from person@oraclelink in
the create or replace view personne_oracle?it doesn't work !
The problem is the dblink ! Without it it's work !
thx for your answer.
