THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
...
- Use ReceiverGBean to specify the information of the current node and port number used for communication.
- Use DisableMcastInterceptor to disable the multicast cluster configurations.
- Use ChannelInterceptorGBeans to specify how the static member are chained together as you can see the configurations of StaticMember1Interceptor and StaticMember2Interceptor.
- Use StaticMemberGBean to specify the information of the second static member and port number used for communication.
To convert this example to a multicast configuration, the DisableMCastInterceptor, StaticMemberInterceptor, and StaticMember definitions need to be removed. Also, the value for the "address" attribute for the TomcatReceiver definition should be changed to "auto".

- Define all the static members involved in the deployment plan for each node.
- Use a reference "NextInterceptor" in interceptor configurations to chain interceptor together as you can see the configurations of DisableMcastInterceptor and TcpPingInterceptor in the sample below. You can control how the client requests are processed by arranging the order of the interceptor chain.

- Use a reference "NextStaticMember" in the second and subsequent StaticMember definitions, but not the last, to chain multiple static members.

See the following deployment plan snippet as an complete example of setting up application-scoped unicast clustering with more than two nodes.
