1. Topology Options

• Hardware load balancer (i.e. BigIP)
• Software Load balancer (i.e Mod_jk)

2. What underlying protocols are used to perform the replication?

• UDP (which is the default)
• TCP (when WAN type clients are used)
• NIO
• tunnel
• loopback

3. What is replicated?

• Stateful Session Beans
• JNDI contexts
• RMI and EJB contexts

4. How is replication done?

• Buddy-buddy
• fine-grain replication

5. How to create a JBoss cluster (for demo purposes only)
a. create 2 copies of the “all” server configuration (name one node1 and the other node2 for example)

1. Edit the ../jboss-eap/jboss-as/server/node2/conf/jboss-service.xml and uncomment the lines below.  This will change the port numbers for node 2 so

it can run simultaneously with node 1 on the same machine.

<mbean code=”org.jboss.services.binding.ServiceBindingManager” name=”jboss.system:service=ServiceBindingManager”>
<attribute name=”ServerName”>ports-01</attribute>
<attribute name=”StoreURL”>${jboss.home.url}/docs/examples/binding-manager/sample-bindings.xml</attribute>
<attribute name=”StoreFactoryClassName”>
org.jboss.services.binding.XMLServicesStoreFactory
</attribute>
</mbean>
b. When starting each node use the following command “run -c <nodename> -b <loopback address>
c. Notice in the console that the second node to start automatically added itself to the cluster.
d. Deploy an application to the “farm” directory of the coordinator node and what all nodes in the cluster deploy the application.
