Great hint. I didn't know that one existed. However, our local DB is V7.3.3 connecting to our remote DB V8.1.7. That hint didn't exist back then. Oh well, I guess we'll burn some DASD for a snapshot.

Thanx,
Alan

Try this:

select --+ DRIVING_SITE(rv)

*
from view_name_at_remotedb rv
where columnA = '...';

Accessing a view across a db link takes a while (fetch phase) when a *local* select statement uses a "where" clause (e.g. select * from view_name_at_remotedb where columnA = '...';). Does anyone know a way (other than a snapshot or materialized view of the remote data on the local db) to force the result set of data (due to the "where" clause) to be resolved on the remote side?
