RE: How to improve queries remotely
I have found in my testing that an inline view works just as well as a normal view . If you are unsure, run explain plan and check the OTHER column in the plan_table. It'll show what is being executed remotely.

Re: How to improve queries remotely
One of the things that has helped me in the past is to set a view on the remote database if I was joining two or more remote tables. Another thing that has helped is to make a snapshot if the data is going to be used often.

Re: How to improve queries remotely
Limit the data you get across the network... Take the query that gets sent across the db link (u can get it from the explain plan or oem sql analyze) and runit on the remote db and check its access path Thanks a lot...
