Performance is improved because the interoperation server is a single-threaded application, and handles only one request at a time. If you install more than one interoperation server, interface services have routing logic to perform basic load balancing across the interoperation servers.
Availability is improved because the system can continue to work if one of the interoperation servers fails. While one interoperation server is down, users can continue to access the database using the others.
To run multiple interoperation servers, start multiple instances of the interoperation server.
All the interoperation servers must be the same version. They must also:
The interoperation servers can be on different machines.
