The on demand router (ODR) is an intelligent HTTP and Session Initiation Protocol (SIP) proxy server in WebSphere® Virtual Enterprise. You can configure the ODR to determine how it handles failure scenarios and how it tunes certain work requests. You can create a cluster of ODRs, which is called a static cluster.
Consider clustering ODRs when you are integrating the Session Initiation Protocol (SIP) ODR with Load Balancer for IBM WebSphere Application Server.
Consider creating a cluster of HTTP ODRs to administer all of the ODRs at one time. If you do not create a cluster, you must administer each ODR individually.
You placed multiple on demand routers in a cluster.
To modify the settings, such as the action type and rule expression, of an ODR cluster, use the wsadmin tool to complete administrative tasks at the cluster level. For more information, see Rules for ODR routing policy administrative tasks and Rules for ODR service policy administrative tasks.
