Hi!
Some developers runs SQL-questions against a 9.2.0.8 Oracle DB. They run against two tables. On with over 300k rows and the other with around 200k rows.
But the response time is really slow from 5 to 40 seconds. And the SQL queries are not that complicated. They do run many full table scans however.
There around 35-40 sessions connected to the DB.
Do you think the DB should run in Shared Server mode instead?
//Hristo, newbie

It is much more complicated than that. It depends:
- on your oracle version
- on the use or not of pga_aggregate_target
- on the global worload
...
So it can be:
- slower
- faster
- same thing
