AMQ load balancing cluster setup - activemq

Question

i know that there is a lot if information about AMQ cluster but i dont know how to setup this..
I need a load balancing cluster, with two machines, and two instances in each machine like 192.168.0.1 (instance1,instance2) 192.168.0.2(instance3,instance4).
My openwire ports are 0.0.0.0:61617 - 0.0.0.0:61620.
Was found some solutions over the internet like:
Instance1
<networkConnectors>
<networkConnector name="instance1-instance3-instance4" uri="masterslave:(tcp://192.168.0.2:61619,tcp://192.168.0.2:61620)" />
</networkConnectors>
<persistenceAdapter>
<kahaDB directory="${activemq.data}/kahadb1" />
</persistenceAdapter>
instance2:
<networkConnectors>
<networkConnector name="instance2-instance3-instance4" uri="masterslave:(tcp://192.168.0.2:61619,tcp://192.168.0.2:61620)" />
</networkConnectors>
<persistenceAdapter>
<kahaDB directory="${activemq.data}/kahadb1" />
</persistenceAdapter>
instance3:
<networkConnectors>
<networkConnector name="instance3-instance1-instance2" uri="masterslave:(tcp://192.168.0.1:61617,tcp://192.168.0.1:61618)" />
</networkConnectors>
<persistenceAdapter>
<kahaDB directory="${activemq.data}/kahadb2" />
</persistenceAdapter>
instance4:
<networkConnectors>
<networkConnector name="instance4-instance1-instance2" uri="masterslave:(tcp://192.168.0.1:61617,tcp://192.168.0.1:61618)" />
<networkConnector name="FAILOVER"
uri="static:(failover:(tcp://192.168.0.1:61617,tcp://192.168.0.2:61619,tcp://192.168.0.1:61618,tcp://192.168.0.2:61620))?randomize=false"
dynamicOnly="true"
networkTTL="4"
duplex="true"/>
</networkConnectors>
<persistenceAdapter>
<kahaDB directory="${activemq.data}/kahadb2" />
</persistenceAdapter>
And it works, connecting to each other, when one node falls down, instance4 reconnect to another with this failover string. But i dont know is it works fine or it doesnt work, tell me pls??
Maybe somebody made LB cluster and can give xml files?Please. And sorry if my english not so good. I am from other country)

Answer 1

The solution to scale out (load balance from a broker perspective) an ActiveMQ deployment is called Network of Brokers. The network consists of multiple logical nodes, which you seem to be setting up. These nodes can be of master-slave type, to cover for machine failure etc.
There are example configs inside the ActiveMQ distribution that you can look at.
