Was it always slow ? Are you monitoring specifics jobs ? If so, have you run tkprof your main SQL statements ?
When running, what are the main ressources Oracle is waiting on ? Have you monitor from the OS ? Are you IO bound or CPU bound ? Cost base optimiser in 805 is not as good as on 8i or 9i.

In researching rule/cost based optimizers, I read that the cost based optimizer was the way to go (although rule had its moments) because that is where Oracle would be focusing any upgrades, enhancements, etc. So I analyzed all tables and indexes. It brought our application to a stand still!! I then deleted the statistics and the application ran like before...slow. I know that I must have missed something although it seemed so straight forward. I verified that all tables were analyzed because I read that this would cause an extra step if all the tables were not analyzed. The database is Oracle 8.0.5. This weekend I will be upgrading to 8.1.7. The operating system is NT 4.0. Does anyone know something that could point me in the right direction? Thank you for your help.
