- Ensure that every object placed in the HTTP session implements java.io.Serializable. The clustering feature serializes the objects when it distributes them to the other nodes in the cluster.
- The deployment descriptor for your Web application, that is the
web.xml
file in the Web archive, must indicate that your Web application is distributable. To do this, insert the distributable element in the deployment descriptor.Code Block XML XML borderStyle solid title Excerpt from web.xml borderStyle solid <?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"> <web-app> <display-name> ... </display-name> <description> ... </description> <distributable> <distributable/> ... </web-app>

Static members in a cluster are defined using org.apache.geronimo.tomcat.cluster.StaticMemberGBean
in the deployment plan. You have to specify all static members within the deployment plan to make sure the application is clustered successfully. Refer to the sample code below for a an application-scoped unicast clustering configuration on one node. The sample assumes there are only two static members in a cluster environment.
A few notes for better understanding of the sample deployment plan:
- Use
ReceiverGBean
to specify the information of the current node and port number used for communication. - Use DisableMcastInterceptor
ChannelInterceptorGBeans
to disable the multicast cluster configurations.Use ChannelInterceptorGBeans to , and specify how the static member are chained together as you can see the configurations ofStaticMember1Interceptor
andStaticMember2Interceptor
. - Use
StaticMemberGBean
to specify the information of the second static member and port number used for communication. - Use
TcpPingInterceptor
to 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 need to should be removed. Also, the value for the "address" attribute for the TomcatReceiver ReceiverGBean
definition should be changed to "auto".

- IPAddress1 is the IP address or host name of current static member.
- TCP_port1 is the TCP port on the current node to listen for session replication data from other static members.
- IPAddress2 is the IP address or host name of the second static member.
- TCP_port2 is the TCP port on the second static member to listen for session replication data from other static members.
Configuration
...
of unicast clustering with more than two nodes
To set up an application-scoped unicast clustering with more than two nodes, ensure that make sure you have done following steps.
...
defined all the static members
...
in the deployment plan for each server node.
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.
