Use the Failover/Pool Sites section to configure pooled UA servers and failover servers.
UA servers are generally pooled for performance improvements. To create a pooled or server, clone the original UA service and add a /port:##### command line switch. Then enter the server in the Failover/Pool Sites table with the same UA Server name, new port number, same Displays folder and DSN.
Failover UA servers could be another instance of the UA server or a UA server on a different machine.
