Home -> Community -> Mailing Lists -> Oracle-L -> WebLogic, Oracle JDBC related
We are in the process of rolling out a Web Appl that uses BEA WebLogic and
Oracle JDBC, thin driver calls to connect to database. These are dedicated
connections (No MTS). The listener is overwhelmed with connection requests
that at times reach 250+ per second. The 'preferred vendor' is blaming it on
the limitation of the Listener, that is not capable of handling this load.
I suspect this fine piece of software is not using JDBC connection pooling. Is there any way to find out if that's indeed the case? I am not involved in this project, and may not get access to the Appl Code. A co-worker is asking me all kinds of questions about Listener problems. The Vendor is suggesting to increase the QueueSize for the listener. They have already created multiple listeners in vain.
I think the Appl code is to blame. I do not know much about Java/EJB etc.. but my hunch is that this EJB container stuff does not smell good. For all I know it could be making a db connection for every single thing and disconnecting.
Anyone dealt with similar issues?
All tips are welcome and appreciated.
All right, the preferred vendor is AMDOCS. Anyone running any of their Web Applications? If so, can you please contact me off-list?
Thanks.
