I am doing some performance testing in Weblogic and the results I got weren't as good as I expected. Weblogic ran so slow. I couldn't figure out what was wrong. I ran weblogic, oracle and client in three different machines in local network and three of them have the same configuration. I did testing before with oracle and weblogic in the same machine and the performance was higher than this time. The envionment settings are just the same. I don't know what affected weblogic performance this time. Could anyone help me?
Could you please explain about the driver(oracle) details.
Which driver you are using?
Thin or OCI driver.
It's hard to say what is happening in your environment without first gaining visibility and figuring out where the performance bottlenecks are located -- the performance problem may exist in the application server layer, database layer, and/or network layer. Figuring out the database and network layers should be fairly straight forward given that there are well-known tools and techniques avaialble. It's much harder to figure out what's happening in the application / J2EE layer.
What version of WebLogic you are using?
use PerformaSure...that might help you
try using PerformaSure from Quest software. We use it with our Weblogic environment and find issues with performance tests
