The loadBalanceHosts parameter is a connection parameter for the JDBC driver to use the load balancing feature. You can specify whether to use the load balancing feature by setting this parameter. However, Connection Manager provides a unique load balancing feature that users cannot specify whether to use or not. Therefore, even if the user sets the loadBalanceHosts parameter to disable the JDBC driver load balancing feature, the Connection Manager load balancing feature is always enabled when connecting to the database via the Connection Manager.
