I've got an application which wants to publish to multiple topics on a non-default stream (i.e. not SYSTEM.BROKER.DEFAULT.STREAM), but rather a stream I'll call A.STREAM.
Using JMS and calling setBrokerPubQueue("A.STREAM"), my publications work fine.
However, when trying to registry durable subscribers on that A.STREAM by calling setBrokerDurSubQueue("A.STREAM"), I get the following exception:
| Code: |
com.ibm.mq.jms.BrokerCommandFailedException: Broker command failed: MQRCCF_Q_NAME_ERROR Reason code 3076
at com.ibm.mq.jms.MQBrokerSubscriptionEngine.openDurableSubscription(MQBrokerSubscriptionEngine.java:1297)
at com.ibm.mq.jms.MQMigrateSubscriptionEngine.openDurableSubscription(MQMigrateSubscriptionEngine.java:547)
at com.ibm.mq.jms.MQSession.createDurableSubscriber(MQSession.java:5025) |
If I simply change the subscribers to register on the system queue: SYSTEM.JMS.D.SUBSCRIBER.QUEUE, it works fine, but I can only receive messages published to the SYSTEM.BROKER.DEFAULT.STREAM queue.
Also, if I change the subscribers to register on multiple queues, one per topic, using SYSTEM.JMS.D.MYAPP.*, I can likewise only receive messages published to the SYSTEM.BROKER.DEFAULT.STREAM queue.
My question is, what in the world do I need to do to register a durable subscriber on a non system default stream? I've read through redbooks, searched the forum all to no avail.
Any help you all could provide is much appreciated. |

Read the books again...
You need to make sure the broker publishes from your non standard queue.
As well as for your subscription: If the queue is non standard it still needs to start as SYSTEM.JMS.D. an alias will allow you to transform a non standard name into a standard name....
Enjoy

Turns out the answer was to specify the durPubQueue on the TopicConnectionFactory used on the subscriber side. Setting this to the name of the Stream that the publications were made on worked.
Subscriptions are using setBrokerDurSubQueue=SYSTEM.JMS.D.MYAPP.* |
