The comparison takes into account the load on nodes sales1-server and sales2-server, respectively.

In the following example, sales.us.acme.com can connect to sales.us.acme.com using listeners on either sales1-server or sales2-server.

Unless multiple address options are configured, the first address in the list is contacted.

This parameter is required when reaching the destination requires more than one address stop.

This parameter is used to enable connections to Oracle Connection Manager.

The number of addresses in the list determines how many addresses are tried.

When set to off, instructs Oracle Net to try the addresses sequentially until one succeeds.

While connect-time failover and client load balancing select an address from a list, source routing connects to each address in the list sequentially.

Table 15-2 describes the tools to configure connect-time failover or client load balancing.

Source routing involves other configuration that goes beyond the scope of this section.

Table 15-5 describes the tools to configure connect-time failover or client load balancing.

In an Oracle9i Real Application Clusters environment, connection load balancing also has the capability to balance the number of active connections among multiple instances.

Depending on the load information, a listener decides which instance and, if shared server is configured, which dispatcher to send the incoming client request to.

If shared server is configured, then the least loaded dispatcher of the selected instance is chosen.

This is achieved by the use of the LISTENER attribute of the DISPATCHERS parameter.

The numbered actions correspond to the arrows shown in Figure 15-2.

The listeners are updated on the load of the instances and dispatchers dynamically.

This can happen if more processing is required on sales1-server.

The number of connections to sales1 (200) is the same as that of its only dispatcher, dispatcher1.

The number of connections on sales2 (300) is the sum of the connections on its two dispatchers, dispatcher2 (100) and dispatcher 3 (200).

In this example, sales2-server is the least loaded node, sales2 is the least loaded instance, and dispatcher2 is the least loaded dispatcher.
