Business Services Server Fault Tolerance
When a machine in the system goes down or is brought down, other machines in the system should gracefully degrade while it is down and reconnect once it is back up. For the Business Services Server the relevant machines are the Security Server and the Enterprise Server. The connection to the Enterprise Server is fault tolerant. If the Enterprise Server is down, the SOAP faults thrown from a called web service are descriptive and indicate the problem. If the Enterprise Server comes back up, subsequent web service calls connect correctly without restarting or any further administration of the Business Services Server. If connections to the Enterprise Server time out the connections are reestablished.
