AQ java errors in recently upgraded 10g database. please help!

The code below is being executed in the following environments-
JDK Version - 1.4.2_05
Oracle JMS API-
Sun Solaris 5.9
Oracle 10.2.0.3



           QueueConnectionFactory qcfact = AQjmsFactory.
                getQueueConnectionFactory(System.getProperty("ORAURL"), null);
            qconn = qcfact.createQueueConnection(System.getProperty("ORAUSER"),
                        System.getProperty("ORAPW"));
            QueueSession qsession = qconn.createQueueSession(true,
                Session.CLIENT_ACKNOWLEDGE);
                         
            String queueName = getQueueNameWithoutSchema();
           
            Queue queue = ( (AQjmsSession) qsession).getQueue(System.getProperty("DBOWNER"), queueName);            
           
           
            QueueReceiver qrecv = qsession.createReceiver(queue);
            qconn.start();

            logger.info("Connected to Queue - " + queue.toString());
            while (true) {
              logger.debug("Waiting for " + pc.getPartnerName() + " message");
              TextMessage msg = (TextMessage) qrecv.receive();
            }


these errors are coming in from the application server side, i am not seeing anything in the ALERT log.

From the code snippet you posted (which is actually incomplete), it looks to me like you are opening more sessions on the application side than the server allows on the database side. Unless you do it elsewhere, I don't see where you actually end the sessions.

As such, I see two options:
1) Increase the number of sessions allowed on the database
2) Manage your active sessions better on the application side (i.e., close them as soon as you can).

Personally, I think you should go with option 2.

Check your SESSIONS parameter setting

You're not trying to open the sessions in a loop by any chance, are you?

and yes, the sessions are being opened inside a loop.  is that problem?

gatorvipCommented:
yes, if you're not closing them accordingly. Either increase the # of sessions allowed, or close the sessions when you're done with them.

we are not getting ANY errors on the database side; so there is no need to increase the number of connections there.  this problem is localized to the client application server where the java application lives

pretty sure this is the solution, we've got the session param set already at the instance level but we have a unix parameter for allowable processes that needs to be throttled up to unlimited.   pretty sure that will fix the issue.   thanks for confirming my suspicions..  i'll wait one week to make sure the unix fix works, then award points.

thanks a million for the input, i love this place.
