I can't think of a reason why you couldn't have each of the three be a 'master' w/a corresponding slave. This is the kind of cluster topology I thought you were after.
http://www.sonicsoftware.com/products/sonicmq/index.ssp Note in the diagram how the primary brokers in each of the clusters has a passive slave that is backing it up. You should be able to do the same with ActiveMQ. However, as James mentioned, maybe all you need is one master/slave pair? Joe ktecho wrote: > > Thanks, Joe.
