What's the full use-case here?  Are you attempting to test server-side message \
load-balancing where messages sent to one node are distributed to other nodes in the \
cluster?  If so, do you have consumers on the other nodes of the cluster waiting to \
receive those messages?  You are using the ON_DEMAND load-balancing policy which will \
only load-balance messages if there is a demand (i.e. a consumer).

Artemis ships with examples of clustered use-cases like this where you can see \
concrete configuration details.  Perhaps one of those might help you.

Also, questions about using the broker should be sent to the user list rather than \
the dev list.

Subject: Artemis - Load balance setup

Trying to implement a load balance topology with two live servers,
tcp://localhost:61616 and tcp://localhost:61617
I am sending the message to tcp://localhost:61616.

load balance not working with the given below config. Only
tcp://localhost:61616 is receiving the message.
     <connectors>
         <connector name="netty-connector">tcp://localhost:61616</connector>
      </connectors>

      <acceptors>
         <acceptor name="netty-acceptor">tcp://localhost:61616</acceptor>
      </acceptors>

      <broadcast-groups>
         <broadcast-group name="bg-group1">
            <group-address>231.7.7.8</group-address>
            <group-port>9876</group-port>
            <broadcast-period>1000</broadcast-period>
            <connector-ref>netty-connector</connector-ref>
         </broadcast-group>
      </broadcast-groups>

      <discovery-groups>
         <discovery-group name="dg-group1">
            <group-address>231.7.7.8</group-address>
            <group-port>9876</group-port>
            <refresh-timeout>60000</refresh-timeout>
         </discovery-group>
      </discovery-groups>

      <cluster-connections>
         <cluster-connection name="my-cluster">
            <address>jms</address>
            <connector-ref>netty-connector</connector-ref>
            <retry-interval>500</retry-interval>
            <retry-interval-multiplier>1.0</retry-interval-multiplier>
            <max-retry-interval>5000</max-retry-interval>
            <reconnect-attempts>-1</reconnect-attempts>
            <message-load-balancing>ON_DEMAND</message-load-balancing>
            <max-hops>1</max-hops>
            <discovery-group-ref discovery-group-name="dg-group1"/>
         </cluster-connection>
      </cluster-connections>

But when I give this (acceptor defining the other server) in each
broker.xml, then the load balance works alright(round-robin)
 
      <acceptors>
         <acceptor name="netty-acceptor">tcp://localhost:61616</acceptor>
         <acceptor
name="netty-acceptor-61616">tcp://localhost:61617</acceptor>
      </acceptors>

So is it necessary? the dynamic addition of a new node might not be possible
then? because then i have to add acceptor element for that server in all
other brokers and restart them all ??
