Based on FAN notification, Tuxedo TMFAN server can receive load balancing advisories that include the load information of each RAC instance. If the change in advised load exceeds the threshold specified in the TMFAN then Tuxedo attempts to balance the connections to the database to match the load information, connecting more servers to the less loaded instance(s).

For more information about configuration, see Introduction to Using Oracle Tuxedo Advanced Performance Pack.
