On Demand Configuration (ODC) enables WebSphere Application Server components, such as the proxy server, to build WebSphere Application Server application deployment, availability, and accessibility information in order to route requests for these applications without any additional configuration at the proxy server.
ODC uses WebSphere Application Server high availability capabilities to publish and subscribe updates. The deployment manager within a cell and the
application servers that have the ODC capabilities typically publish the updates that are subscribed to by intermediaries such as the proxy server. ODC is supported on WebSphere Extended Deployment V5.1 and on WebSphere Application Server V6.0 and V6.0.x and higher versions of WebSphere Application Server Network Deployment.
