You may want to look at using materialized views. They are easy to setup
and can be refreshed manualy or automaticaly.

Please respond
to ORACLE-L
Hello all:
We have an application that is having slow response time against an 8i
database, I would like to improve the response time. This is a web based
application accessing the database with about 2000 users. Most of the
application queries are based on complex joins on 4 big tables with each
having over 5 million rows( biggest table has 18 million rows). I have
tuned the Package queries for the best explain plan possible, but still do
not seem to make dramatic change in the response time. Though, I was able
to make significant headway tuning these packages by bringing down response
times from 7 minutes to under 3 minutes. But this is not an acceptable
response time from a web-application perspective.
I am considering creating data cubes based on the most frequently used join
conditions and pre-populate them on a nightly basis or use triggers to
update the cube simultaneously.
I am hoping that this enhance the response times.
I would greatly appreciate your suggestions or opinions on this idea. If
you
have an alternative/better way of achiving this please enlighten me.
Thank very much.
Srini Rajendran.
