Demand based propagation of messages across networks does require
advisories to work. You could try explicitly setting up the
destinations you want to be propagated around the network - if you
don't want to use advisories (though they are good!)

You must destroy the connection and create a new connection / session
etc. We don't have a fail over transport but you are welcome to write
one and donate it :)

I cannot find enough documentation on message selectors but have many

Message selectors are more like fliters right? If so, what is the underlying
selection policy of the broker? Age, priority, moon phases?

When i turn off the Advisory Support the Network of Brokers doesn't work. Is

Hi Mario,
Thanks!
The problem does not occur only when ActiveMQ shuts down abnormally. It also
seems to occur when a db connection is lost due to network abnormalities,
while Active MQ is running.
Unfortunately, we do need to run in master / slave mode, so turning off db

I think that's a reasonable scenario, Oracle will actually have
trouble detecting them fast enough. I don't know if there's a setting
in Oracle that would speed up the checks. MySQL and MS SQL Server

Perhaps stating the obvious... this seems to happen when there is some
network instability and the connection to the database is lost. Because the
connection is lost, ActiveMQ is unable to release the lock.
The lock then stays on the table until Oracle is good and ready to delete
it, which can be

Thanks for the explanation - I made the following change to the POM which
resolved the problem, but I have to admit it was more luck that judgement!

Cool, that's great!
Do you know of a workaround in the meantime?

Lingo has a dependency on ActiveMQ 4.0. As far as I can tell activemq 4.0
does not have ConnectionInfo.isClientMaster(). Somehow through maven
dependency resolution, the earlier ActiveMQ is higher in the chain than the
declared version, thus it finds the older ConnectionInfo class with no

Hi guys,
I have looked into the API documentation at:
http://activemq.apache.org/maven/activemq-core/apidocs/org/apache/activemq/ActiveMQXAConnectionFactory.html
However, I couldn't find any information or confirmation regarding when and
how should the ActiveMQXAConnectionFactory should be used.

Hi Rob,
I'm afraid I didn't get any time today, and my project has moved on to
not using JMS persistence for messaging. We are using custom
checkpointing instead, which is a bit more lightweight than full JMS
persistence.
I'd still like to see this issue fixed, so I'll try to find some time
