Multiple clustered CHA servers and co-resident clients

In this topology, the CHA servers and CHA clients are in the same cluster. To each client, the clustered servers appear as a single server.

However, to maximize the performance provided by using local interfaces in this topology, do the following:
  1. Set the CHASession and CHAInstance EJBs to run on the same physical machine.
  2. Set the business process to run on the same machine as the CHASession and CHAInstance EJBs.

The deployment diagram is identical to the diagram in Single CHA server with co-resident clients.
