[jboss-user] [JBoss Messaging] - Re: Distributed queue, HA-JMS/singleton basic questions

Hello kapucin - comments inline "kapucin" wrote : Hello | Could someone, please, explain what's the advantage of using HA-singleton vs Distributed queue (DQ)? | Is HA-singleton simply the old way for providing the fail-over functionality, and should not be used as DQ is better? | JBoss MQ ia really a single server JMS server - i.e. it only ever has one node active in the cluster at any one time. This differs with JBM where all nodes are active. HA singleton was primarily designed of getting the single server JBoss MQ to work in the cluster - it handles automatically starting up a new instance if failure occurs. JBoss Messaging was designed to have true clustering so HA singleton is not necessary. anonymous wrote : | | Can JBM be configured for ha-singleton, although it seems to defeat the purpose of DQ? | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4104294#...
