Configure peer-to-peer replication with JMS

The Java™ Message Service (JMS) based peer-to-peer replication mechanism is used in both the distributed and local WebSphere eXtreme Scale environment. JMS is a core-to-core replication process and allows data updates to flow among local ObjectGrids and distributed ObjectGrids. For example, with this mechanism you can move data updates from a distributed eXtreme Scale data grid to a local eXtreme Scale grid, or from a grid to another grid in a different system domain.

Before you begin

The JMS-based peer-to-peer replication mechanism is based on the built-in JMS-based ObjectGridEventListener, For detailed information regarding enabling peer-to-peer replication mechanism, see JMS event listener.

See Enable the client invalidation mechanism for more information.

The following is an XML configuration example to enable a peer-to-peer replication mechanism on an eXtreme Scale configuration:

peer-to-peer replication configuration - XML example
<bean id="ObjectGridEventListener" 
    <property name="replicationRole" type="java.lang.String" value="DUAL_ROLES" description="" />
<property name="replicationStrategy" type="java.lang.String" value="PUSH" description="" />
<property name="jms_topicConnectionFactoryJndiName" type="java.lang.String" 
        value="defaultTCF" description="" />
<property name="jms_topicJndiName" type="java.lang.String" value="defaultTopic" description="" />
<property name="jms_topicName" type="java.lang.String" value="defaultTopic" description="" />
<property name="jms_userid" type="java.lang.String" value="" description="" />
<property name="jms_password" type="java.lang.String" value="" description="" />
<property name="jndi_properties" type="java.lang.String"
