Using the Java Connection Factory

Using Load Balancing

Load balancing enables a Java Connection Factory to distribute server load between a cluster of redundant servers. For more information about load balancing, see Overview of Load Balancing in the SAS Intelligence Platform: Application Server Administration Guide.

Note: Load balancing can be used with SAS Stored Process Servers and SAS Workspace Servers only . [cautionend]

A connection factory that is configured for load balancing uses a group of redundant servers called a load-balancing cluster to send connection requests to the server that has the least load. If a server in the load-balancing cluster is unavailable, then connection requests are sent to other servers instead.

The following code fragment configures a connection factory to use load balancing:

String classID = Server.CLSID_SAS;
Server server0 = new BridgeServer(classID,foo0.bar.abc.com,1234);
Server server1 = new BridgeServer(classID,foo1.bar.abc.com,1234);
Server[] servers = {server0,server1};
Cluster cluster = new LoadBalancingCluster(servers);
ConnectionFactoryConfiguration cxfConfig =
   new ManualConnectionFactoryConfiguration(cluster);

Note: Load-balancing clusters require additional configuration on the server side. For details, see Planning and Configuring a Load-Balancing Cluster in the SAS Intelligence Platform: Application Server Administration Guide. [cautionend]
