I have a WebSphere MQ contract that I've setup. I have the queue configured to deliver a message that is retried 5 times to a separate queue for poison processing. I interact with the service using the WCF Channel provided by WebSphere MQ v 7.01.
While my service is connected, things work perfectly. As soon as the service disconnects, the poison messages reappear in the primary queue. Restarting the service instantly puts the messages back from the primary queue into the poison queue. What do I need to do in order to get the messages to stay in the poison queue after the service disconnects from the queue? Is this a bug in my code or a bug in the WCF Channel for MQ Series?
The code is currently in POC mode, so I'm hosting the service on a Window. The class has these attributes:
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
[AssuredDelivery()]
public partial class MainWindow : Window, IWmqEndpoint
Service contract is:
[ServiceContract()]
public interface IWmqEndpoint
{
[OperationContract(IsOneWay = true)]
void SendMessage(string message);
[OperationContract(IsOneWay = true)]
void SendComplex(PersonName name);
}
The main queue is persistent, otherwise, default settings. Ditto for the poison queue.
Queue setup:
1.Backout request queue: wcf.inbound.poison
2.Backout threshold: 5
3.Harden get backout: Not hardened
4.NPM class: Normal |

Have you verified that you are committing your put to the poison queue?

| Also, the move to the poison queue is happening automatically. It's not clear to me how I would commit this put using the WCF channel. |
