Routing requests to ODC-compliant application servers in other cells

On demand configuration (ODC) enables product components, such as the proxy server, to build application deployment, availability, and accessibility information 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 the high availability capabilities of the product 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.

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. After the cells are linked with core group bridges, the proxy server will route to the application without additional configuration. To view your core group bridge settings, in the administrative console, click Servers > Core groups > Core group bridge settings.

Important: Cross-cell failover is not supported. If the same application is installed on both the local cell and in one or more remote cells, and the application or application servers in the local cell fail, then the ones in the remote cell are not used. The proxy server always routes to the local cell even if the resource is available in a remote cell.

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. If you want to use CGB_ENABLE_602_FEATURES, enable it on all of the cells involved.
  2. Restart all processes that are now bridge interfaces.

What to do next

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