Using the SAP Sybase IQ network client to balance the query load among multiplex query servers requires an intermediate system that is able to dispatch the client connection to a machine in a pool.
To use this method, on the client system you create a special ODBC DSN, with the IP address and port number of this intermediate load balancing system, a generic server name, and the VerifyServerName connection parameter set to NO. When a client connects using this DSN, the load balancer establishes the connection to the machine it determines is least loaded.
