Subject Re: durable subscription problems
Date Mon, 23 Aug 2010 23:57:57 GMT
As i continue to work on this problem and dig further into the AMQ docs, additional clarifying
questions have come up about network configuration in a store-and-forward scenario in which
the broker A publishes to topics on broker A, and broker B subscribes to identically-named
topics on broker B. i want to create durable subscriptions so the broker B will eventually
receive messages published when it's offline.

1) Is a single duplex networkConnector on broker B sufficient? (section 10.2.1 of "ActiveMQ
in Action" makes it seem like the answer is "yes".)

2) Is the "conduitSubscription" attribute required? (example 10.3 in "ActiveMQ in Action"
makes it seem like the answer is "yes".)

3) In the networkConnection on broker B, do i need to define "durableDestinations" for the
topics on broker A?

4) If the answer to (3) is "no", is it possible to point to the topics on broker A using the
">" wildcard in the "<dynamicallyIncludedDestinations>" or "<staticallyIncludedDestinations>"
in broker B's networkConnector?

thanks in advance,
Joe

Hi Joe,

this sounds like a bug. Did you tested it with some newer version of
ActiveMQ (as there was a lot of work in that area since 5.0.3)

Can you test newly released 5.4.0
http://repo1.maven.org/maven2/org/apache/activemq/apache-activemq/5.4.0/
and see if the problem still exists?

If it's still there, it would be great if you could raise a Jira
issue, ideally with a test case.

Cheers
