1. Re: Example how to use LoadBalancingFactory
Can you give more info on your questions. for example:
What do you refer LoadBalancingFactory to? JBM version? What purpose do you want it for? Thanks. -
2. Re: Example how to use LoadBalancingFactory
I try to test max number of clients in Jboss messaging 1.4.2.
I started two Jboss instance:run.bat -c node1 -b 10.113.1.158 -Djboss.messaging.ServerPeerID=1 run.bat -c node2 -b 10.113.1.218 -Djboss.messaging.ServerPeerID=2
and in my client I used:ConnectionFactory cf = (ConnectionFactory) context.lookup("/ClusteredConnectionFactory");
but LoadBalancing did not work.
After that I guess I must use LoadBalancingFactory.
Maybe I mistake, I'm new to all this. -
3. Re: Example how to use LoadBalancingFactory
JBM 1.4 supports round-robin policy. I think you didn't set up your cluster correctly.
For clarity, 'loadbalancing' means for the connection here, that is, the connections to the cluster are round roubined across the nodes.
Take a look at distributed-queue example, if you can run this example, the cluster will be ok, and load balancing is working. -
4. Re: Example how to use LoadBalancingFactory
I started two JBoss 5.0.1GA instance:
run.bat -c node1 -Djboss.service.binding.set=ports-01 -b 10.133.1.158 run.bat -c node2 -Djboss.service.binding.set=ports-02 -Djboss.messaging.ServerPeerID=1 -b 10.133.1.218
node1 and node2 are copy of all configuration
After that I make project in eclipse, in the project i copy 'distributed-topic' example from jboss-messaging-1.4.2GA-sp1...
When I debug application... application will stop on line:cf = (ConnectionFactory)ic.lookup("/ClusteredConnectionFactory");
I checked in connection-factories-service.xml file, and i have:<mbean code="org.jboss.jms.server.connectionfactory.ConnectionFactory" name="jboss.messaging.connectionfactory:service=ClusteredConnectionFactory" 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="JNDIBindings"> <bindings> <binding>/ClusteredConnectionFactory</binding> <binding>/ClusteredXAConnectionFactory</binding> <binding>java:/ClusteredConnectionFactory</binding> <binding>java:/ClusteredXAConnectionFactory</binding> </bindings> </attribute> <attribute name="SupportsFailover">true</attribute> <attribute name="SupportsLoadBalancing">true</attribute> </mbean>
I did not do any editing on Jboss, just download, unzip and start -

OK. I guess you need to change the jndi.properties in the example's etc dir.

7. Re: Example how to use LoadBalancingFactory
Works.... Thanks
I mistake in client Contex.
One more question, did subscriber must listen all nodes in cluster... as in the example 'distributed-topic' -

No, it needn't. The load-balance is transparent to applications. -

When I create just one listener in cluster with two nodes... I receive only half messages... :( -
10. Re: Example how to use LoadBalancingFactory
Did anyone known what is problem, load-balance is not transparent to client.
My Publesher works OK, one time is publish on node1 other time on node2... But Subscriber, could not listen all nodes... only one.
