How to use an Object Type from Another Database

Question

Hi,
I have this requirement that I need to call a stored procedure from another DB (db1) but I am having a problem with this because one of the input parameters uses an object type defined in that DB (db1). Is it possible to use an object type from another database? TIA!

At least for queries, but I think also for procedure arguments..You (both) probably missed my post?
We can't use a remote type as procedure argument, even with the same OID.
It's OK for query on a remote object column though :
SQL> conn remote_user@remote_db

  3  /
Type créé.
SQL> create table mytable (col1 mytype);

SQL> create or replace function myfunc (p_in in mytype) return number
