XMS.NET hanging indefinitely on factory.CreateConnection(“username”, null);

问题

I am trying to connect to an existing JMS queue with a .NET client. I know the queue is working, I already browsed it using IBM MQ Explorer.

In the following code, the call to factory.CreateConnection keeps hanging - it does not jump to the next line, in does not show any error message. It even doesnt consume any CPU.

Are there any options that I should try to get it working (or at least make it show me an error message of any kind)?

private static IConnectionFactory GetConnectionFactory()
    {
        var factoryFactory = XMSFactoryFactory.GetInstance(XMSC.CT_WMQ);
        var cf = factoryFactory.CreateConnectionFactory();

        cf.SetStringProperty(XMSC.WMQ_HOST_NAME, "server address");
        cf.SetIntProperty(XMSC.WMQ_PORT, portnumber);
        cf.SetStringProperty(XMSC.WMQ_CHANNEL, "channelname");
        cf.SetIntProperty(XMSC.WMQ_CONNECTION_MODE, XMSC.WMQ_CM_CLIENT);
        cf.SetStringProperty(XMSC.WMQ_QUEUE_MANAGER, "queuemanager");
        cf.SetIntProperty(XMSC.WMQ_BROKER_VERSION, XMSC.WMQ_BROKER_UNSPECIFIED);

        return (cf);
    }

The main method has the following:

var factory = GetConnectionFactory();
var connection = factory.CreateConnection("username", null);

回答1:

I don't see any problem with your code, tested it with MQ v8 and works fine. I would suggest you to do:

1) XMS can run in unmanaged mode also. So change

cf.SetIntProperty(XMSC.WMQ_CONNECTION_MODE, XMSC.WMQ_CM_CLIENT);

cf.SetIntProperty(XMSC.WMQ_CONNECTION_MODE, XMSC.WMQ_CM_CLIENT_UNMANAGED)

and see if that helps.

2) When the call hangs, break into debug and see the call stack to determine the point of hang. It could be waiting on some system event if no CPU is being consumed.

3) Open a PMR with IBM.
