Who's calling who??

I need a pointer

I have the following setup:

     Box1 Box2

• ----

c1-- db1 --dblink-- db3

c2-- db2 --dblink --/

that is box1 has 2 databases, each having dblinks to db3. Clients can connect to either db on box1. In db1 and db2 there is a view which points to db3 (create view myview as select * from remotetable_at_db3). On remotetable there is a before insert trigger. I'd like to capture which db the insert originated at and stick that value in the remotetable.

I can't change the code on db1 or db2!

How can I determine the dbname (or anything else indicative) for the calling db. Using SYS_CONTEXT('USERENV','IP_ADDRESS') I can determine the IP address of the caller, but that doesn't help me because there are more than one database at the IP. All the other sys_context attributes give me info from db3.

Are there some other sql functions, pl/sql function I can use? Help?

Thanks
