Bill,
Also, you don't want to join remote tables together. Create a join-view on
the remote database instead.

Bill,
Queries across DB links are pretty messy. Check Metalink I found some
information there, particularly on tuning SQL*Net/Net8. Outside of that
there
is not too much you can do. One thing you should try to minimize if
possible is
queries that have a mix of local and remote tables. In that case since the
local DB has no idea of what the indexes are on the remote system, it
sometimes
decides that the best way is to create a temp table locally of all that
remote
data * then perform the joins. Needless to say that temp table is not
indexed.

Hello,
We seem to have more and more questions regarding query
performance across DB Links, and how to improve it.
I have the Gurry/Corrigan book, but can't find anything on
this specific topic.
Can anyone point me to a good whitepaper or other article
regarding query performance across DB Links?
Thanks
