THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
...
A few notes for better understanding of the sample deployment plan:
- Use
ReceiverGBeanto specify the information of the current node and port number used for communication. - Use
ChannelInterceptorGBeansto disable the multicast cluster configurations, and specify how the static member are chained together as you can see the configurations ofStaticMember1InterceptorandStaticMember2Interceptor. - Use
StaticMemberGBeanto specify the information of the second static member and port number used for communication. - Use
TcpPingInterceptorto send a ping to another member periodically. You can manage ping interval by setting the interval attibute forTcpPingInterceptor. It is a good practice to set interval to 240.
To convert this example to a multicast configuration, the DisableMCastInterceptor, StaticMemberInterceptor, and StaticMember definitions should be removed. Also, the value for the address attribute for the TomcatReceiver ReceiverGBean definition should be changed to auto.

Interceptors can perform actions when a message is sent or received. Use a reference NextInterceptor in interceptor configurations to chain interceptors together. You can control how the client requests are processed by arranging the order of the interceptor chain. In the following sample code, when the TcpFailureDetector intercepter catches errors, it calls the next interceptor StaticMember1Interceptor. The static member referenced inside StaticMember1Interceptor, static member 2 in this example, will immediately take over the work of the first static member.
...
All the static members involved should be defined in the deployment plan as well as the relationship between these static members. Use a reference NextStaticMember in the definition of each static member, except for the last one, to chain static members together. When static member 2 in this example fails to take over the work, static member 3 will immediately take over the work. It is the same for longer static member chain. When a static member fails to take over the work of the previous static member, it calls the next static member in the chain. The request is passed along until a static member can handle the work or it gets to the end.
