Subject [jira] Commented: (AMQCPP-315) Advisory messages do not work with multiple listeners
Date Mon, 30 Aug 2010 21:07:41 GMT

Timothy Bish commented on AMQCPP-315:
-------------------------------------

There's really not "right" choice, if you need SSL the use the SSL configurations but be aware
they require that you have OpenSSL installed and accessible to the project.  If you don't
need SSL then just use the non-SSL configurations.

> We found that the advisory messages do not work as expected when there are multiple consumers
listening to the same advisory topics.
> We have three applications, AdvisoryMessageListener, MessageListener, and MessageSender.
> AdvisoryMessageListener listens to the following two topics:
> ActiveMQ.Advisory.Consumer.Topic.cpp.itemLookup
> ActiveMQ.Advisory.Producer.Topic.cpp.itemLookup
> MessageListener listens to topic: cpp.itemLookup
> MessageSender sends messages to topic: cpp.itemLookup
> If there is only one instance of AdvisoryMessageListener , then everything work fine.
We can get the advisory messages when we start/shut down MessageListener or MessageSender
. However, when we start a second instance of AdvisoryMessageListener , it seems to knock
out the existing connection of the first  AdvisoryMessageListener. The first instance can
no longer receive any advisory messages after that. 
> This problem could be related to the problem reported in jira item "AMQCPP-314 Starting
app with Com using cms destroys connection of other app. New problem with recent lib version".
However in our problem,  we do not have any COM layers.
