Subject regarding use of Advisory messages for node failure in a Cluster
Date Wed, 14 Aug 2013 08:44:04 GMT

My architecture uses Jboss+ActiveMQ (in integrated mode)
We have achieved HA (high availability) & HS (High Scalablity).

A high level design looks like the below

Query is - when the primary node fails, the secondary node acquires a lock
on the database and becomes master (HA).

Is is possible to use Advisory messages - to let know my application as to
which node has gone down and which node has acquired the lock on the

Our application displays the Queue statistics (count, depth of messages etc)
in  the UI
Intention is - if and when a node acquires a lock and becomes the Primary
node, I let the broker broadcast its IP address to the application so that -
the app can listen to *that* specific broker's JMX to get Queue/Topic

Is this a right usage of Advisory messages?
