Websphere/Oracle 11 - much more Heap Usage than with Oracle 10?

Up vote 0 down vote favorite share g+ share fb share tw.

While testing our application with Oracle 11 (previously, we had Oracle 10), we saw that our server uses much more heap space. It seems as it has something to do with T4CConnection/T4CPreparedStatement; there are 500 objects of T4CPreparedStatement allocated. Someone told me, that Oracle 11 is using SoftReferences to keep the connection pool; but we don't need that.

Is that correct? Could that be the problem for the increased heap space? If yes - how can we avoid connection pooling?

Thanks a lot! Oracle websphere link|improve this question edited Mar 1 '11 at 7:37 asked Mar 1 '11 at 7:23swalkner36731435 89% accept rate.

The answers to these questions may have something to do with the problem you're experiencing. Have you checked the statement pool size, for example?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
