Hi experts,
I need some help pin pointing a really big problem we're having right now regarding performance of ADF applications on a websphere 7 application server. I'm using JDeveloper 11.1.2.4.0.
First, a little background. Our applications used to run well (about late November). Our server team did some consolidation of the servers, and put more applications on our Websphere test servers. The same ADF builds we used back in November now have painfully slow response times. For example: when a user tries to create a new row, there's around a 40 second delay. Previously, it would be almost instantaneous. The delays are exclusive to database transactions (insert/edit row items, along with intermittent delays when scrolling through tables). I've been told the database server is running optimally as well. I trust this assessment, because running it locally from the integrated weblogic servers show original performance speeds.
Now, I've been in contact with the app server admins (I don't have access to the servers). They've repeatedly told me that the server is not overloaded, or out of memory, and that everything should be fine. They've suggested that I look into performance of the applications. I'm skeptical, but I have been looking into performance tuning of the applications. Anything that can help with performance is a good thing.
If our ADF applications were performing well previous to the server shuffle, and now it they are not, is there any clear server settings that we should be looking for? I would like to communicate to the server team some options they can look into that might be causing ADF applications to perform slow, but not show any server overload. In addition, is there any obvious application performance tuning that I might need to implement?
I'm expecting more questions than a clear cut solution at this point. If you need more information, please let me know and I'll do my best to get you what you need.
Thanks!
