Answer 1

Your open option does not include MQOO_INQUIRE which is a must for getting queue depth. I expected a MQRC 2038 because MQOO_INQUIRE option was not specified.

Not sure why you are initializing MQEnvironment also and you are passing a properties hash table to MQQueueManager constructor.

Anyway here is the sample code that gets queue depth for a local queue.

public static void getQueueDepth()
{
            String qManager="QM1";
    int port_num=1414;
    int openOptions =  CMQC.MQOO_FAIL_IF_QUIESCING + CMQC.MQOO_INPUT_SHARED + CMQC.MQOO_INQUIRE;

    try {
            Hashtable props = new Hashtable();

            props.put(CMQC.HOST_NAME_PROPERTY, "localhost"); 
            props.put(CMQC.PORT_PROPERTY, port_num);
            props.put(CMQC.CHANNEL_PROPERTY, "SYSTEM.DEF.SVRCONN");

            MQQueueManager qMgr = new MQQueueManager(qManager, props);

            MQQueue destQueue = qMgr.accessQueue("SYSTEM.DEFAULT.LOCAL.QUEUE",   openOptions);

            System.out.println("E_RETRY size:" + destQueue.getCurrentDepth());
            destQueue.close();
            qMgr.disconnect();
    }catch(MQException mqe){
        System.out.println(mqe);
    }
}

Is it possible the properties of the queue are different between the v6 and v7 queue managers? The documentation for the error message indicates this can occur with a cluster queue that resolves to a remote instance of the queue.

Have you verified that destQueue is in fact a valid queue?
