Home -> Community -> Mailing Lists -> Oracle-L -> Performance Problem
We currently have an application we are trying to speed up. 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.
