Configuring WebSphere servers

Install the Oracle client in the hosts where you plan to install WebSphere. Install WebSphere as described in the manual, using the OCI driver to connect the WASs to the databases created. Since we use the global net service name, which is independent of individual nodes, the failover is transparent to WebSphere. For CTF, WebSphere receives a few StaleConnectionExceptions during an OPS/RAC failover, and WebSphere handles these exceptions automatically. WebSphere usually works automatically after an OPS/RAC/TAF failover.

In summary, although OPS/RAC uses non-IP failover, it still needs platform-specific cluster software to provide cluster management and inter-process communication. OPS/RAC failover takes a very short time. It is almost instantaneous failover, because non-IP takeover is used and no restarting of the database instance is needed. WebSphere establishes connections immediately after a failover, and clients observe very few failures.
