Routing requests to ODC-compliant application servers in other cells

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. If you want to isolate proxy servers with firewalls, place them in a cell that is separate from the applications and configure the core group bridge service.

About this task

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 higher versions of WebSphere Application Server Network Deployment.

You can configure the proxy server to route requests to applications that are hosted in other cells. The core group bridge service provides communication between a cell with a proxy server and a cell with a target application. Once the cells are linked with core group bridges, the proxy server will be able to route to the application without additional configuration. You can find core group bridge settings by clicking Servers > Core groups > Core group bridge settings in the administrative console.

The basic steps to configure cross-cell routing are configuring and enabling core group bridges in the cell that the proxy server belongs to, and in each of the other cells that are being routed to. The core group bridges need to be configured with the same access point group name.

Procedure

  1. Create bridge interfaces, peer access groups and peer ports for cells. The peer access point group name must be the same in the cells.
  2. Restart all processes that are now bridge interfaces.

What to do next

If security is enabled, it must be enabled in all cells for the core group bridge service.
