Hi,
I simulated a cluster environment with two MQ-Server installations on two different nodes, each has a full repository. On QMGR A i defined a local queue:
DEFINE QLOCAL('MY_REQUEST_QUEUE') REPLACE
,which is refered to by a QALIAS queue on the same node:
DEFINE QALIAS('REQUEST_QUEUE') CLUSTER('MYCLUSTER')
DEFBIND(NOTFIXED) TARGQ('MY_REQUEST_QUEUE') REPLACE
So the aliasqueue is visible on QMGR B as it is defined for the cluster.
I ensured this with mo71, which showed me the queue "REQUEST_QUEUE" in the queue list of QMGR B as cluster queue as expected.
Now I want to access QMGR B from a Java-Client on the same node as QMGR B in bindings mode. So the .bindings file looks like:
DEFINE XAQCF(MQConnectionFactory) QMANAGER(B)
DEFINE Q(RequestQueue) QUEUE(REQUEST_QUEUE) QMANAGER(B)
If I now want to access "RequestQueue" via the JMS-API, it tells me, that Queue "REQUEST_QUEUE" is unknown for QMGR B. ..Why ?
It works though if I change the bindings definition into:
DEFINE Q(RequestQueue) QUEUE(REQUEST_QUEUE) QMANAGER(A)
But this is not, what I want to do, because the client shouldn't know where the QALIAS-queue is defined.
Is there any restriction in using qalias queues that are defined as cluster queues when using them binding mode ?
Involved are
for QMGR A: MQ-Server on WindowsXP Version: 6.0.2.0
for QMGR B: MQ-Server on Solaris Version: 530.10 CSD10
Thx for your help in advance,
Rainer |

If you don't want the client to know where the QALIAS is defined, then don't specify anything for QMANAGER in Queue Destination.

Read the cluster manual --- cluster 101 
The queue is not hosted by qmgr B. Specifying the qmgr makes the program / JMS look for a queue hosted by the qmgr.
If you leave the qmgr field blank in your JMSAdmin definition it should work.

That's a point, Peter. The description in the documentation is valid for a QCF, but not for the same property under a Queue Destination.
There's a "Feedback" button at the bottom of most every page in the Info Center.

Thx for your help,
omitting the QMANAGER definition perfectly works for me.
