We have a ClusterPullConnectionFactory defined at the connection-factories-service.xml - <mbean code="org.jboss.jms.server.connectionfactory.ConnectionFactory" name="jboss.messaging.connectionfactory:service=ClusterPullConnectionFactory" xmbean-dd="xmdesc/ConnectionFactory-xmbean.xml">   <depends optional-attribute-name="ServerPeer">jboss.messaging:service=ServerPeer</depends>   <depends optional-attribute-name="Connector">jboss.messaging:service=Connector,transport=bisocket</depends>   <depends>jboss.messaging:service=PostOffice</depends>   <attribute name="SupportsFailover">true</attribute>   <attribute name="SupportsLoadBalancing">true</attribute>   </mbean> and the line <attribute name="ClusterPullConnectionFactoryName">jboss.messaging.connectionfactory:service=ClusterPullConnectionFactory</attribute> in our messaging-service.xml I am also attaching the entire files.

(they are not in our example). --Yes, if a node is down, its messages won't be sucked. However they may be 'failover'ed to other nodes. Our problem is that a) the messages are stored in the DB b) the node that wrote them is taken out c) The messages are readable only if the node that wrote them is up. I guess this is a 'failover' configuration issue. When a 'node' is taken out, there is always a node in the cluster that will 'merge' the dead node's messages over and deliver them. However if a node is shutdown normally, it may or may not be failed over, depending on a property called 'FailoverOnNodeLeave'. By the way, JBoss Messaging is now in maintenance mode, i.e. no more community releases since (only in EAP). I'd suggest you have a look at HornetQ, the successor to JBM and with richer functionalities and better performance. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/588604#588604] Start a new discussion in JBoss Messaging at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
