MQSeries.net :: View topic - Error Code 2082 when resolving queue over cluster

I am getting the error code 2082 (MQRC_UNKNOWN_ALIAS_BASE_Q) when trying to resolve a queue local over a cluster.

My environment is set up as follows; I have got an MQ cluster with two queue managers QM_A and QM_B. QM_B act as the gateway into the cluster and all connection must pass thru QM_B as this is where we implement our security checks.

An application connection to QM_B over MQ client connection. This application is a 3rd party product over which we have no control. Messages arrive to a queue local on QM_B from QM_A. The application is design to poll this queue on QM_B and then send responses back to QM_A via a queue alias. Thus;

QA(alias on QM_A for request) -----> QL(clustered queue on QM_B for request)

QL(clustered queue on QM_A for Resp) <--- QA(alias on QM_B for Resp)

All queue objects are defined with the attribute DEFBIND(NOTFIXED). When the application tries to open the queue on QM_B, I get the error code 2082, suggesting that MQ is trying to resolve the target on the local queue manager, QM_B. However, this should be being resolved over the cluster to the QM_A.

I suspect the application is opening the queue alias using code like this;

MQQueue q = qmgr.accessQueue("QA on QM_B", openOption, "QM_B", null, null);

I have tested this idea on a small sample application and I also get 2082.

Has anyone come across this and found a solution around this problem. I know if I omit the QM_B in the method above it works, but for this application we have not access to the code.

Thankx
