Subject Re: [Spam: 5.0] Durable Topic subscriber
Date Fri, 02 Mar 2007 15:22:34 GMT

The testcase is

There are 2 machines Machine A, B. Each of them running single brokers each
(BrokerA, BrokerB). The dispatch policy is setup on both brokers as follows
<dispatchPolicy>
       <strictOrderDispatchPolicy />
</dispatchPolicy>

A Topic publisher is attached to BrokerA (PubA) is publishing 1000 messages
to 'MyTopic'. And the Durable topic subscriber (SubB) attached to BrokerB
reads the messages from BrokerB. Now to test the message order while PubA is
sending messages stop SubB (say after receiving 230 msgs). So that there are
messages left in the Topic for the durable subscriber SubB (1000-230). Now
when all the messages are published there are 1000-230 messages on the
MyTopic channel. When SubB connects to BrokerB again the messages received
on SubB is not in the order as messages send by PubA.


Kind regards
Matt
