Thanks for updating the ticket.

None of the queries we fire take more then 5-10 ms.  Also all the connections are already closed in a finally block. So no way that we aren't closing the connections.

Actually  AvailableConnectionCount + InUseConnectionCount is lesser then max-pool-size configured in oracle-ds.xml. Below is the oracle-ds.xml.

Does the pool for oracle DB conns is related with queueing feature(by this i mean the pool for hypersonic DB). Several times we have seen these 2 problems going hand in hand.

Thanking in advance.
