Advanced Features of Oracle Net Services

Address List Parameter LOAD_BALANCE(Client Load Balancing):
When set to on, instructs Oracle Net to progress through the list of protocol addresses in a random sequence, balancing the load on the various listeners. When set to off, instructs Oracle Net to try the addresses sequentially until one succeeds.

This is different from runtime connection load balancing feature which is based on load. (This feature is automatically enabled in shared server configuration and uou must use remote_listener to enable this feature in dedicated server configuration)

Transparent Application Failover(TAF) which is also called runtime failover is controlled by parameter failover_mode and connect-time failover is controlled by parameter failover.
