Answer 1

I have a similar problem where in I close the Result set, Statement and close the connection in a finally block. Even though, the connection.close() executes sucessfully, with no exceptions being thrown, I still see the connection opened in ORacle. This builds up connections for our application and by the end of the day we are up with about 500 connections open and rising.
After closing the connection, I did check the value for connection.isClosed() and it still says false (like before the connection was closed). Since we are using a custom Connection manager to pool the connections, my interpretation is that even after the connection is closed, it doesn't get released. I have tried setting the connection to Null, used the finalize method to still check for connection != null and do one more close(), but still the connection is still open.
Am I mistaken in my thinking that even though the connection seems to be closed(), it doesn't get released until the GC runs and picks it for disposal? For every job, after the process is completed we have about 7 open connections and at times the number stays at 7 for some more jobs (Web application driven by servlets and some rmi in the background process). I thne see a surge in the connection after some more jobs are processed and so am not sure whether its the connection manager to blame. Could any one have any pointers on this issue.
Thanks for your response.
