Using Failover

Failover enables a Java Connection Factory to redirect connection requests in the event of server unavailability.

Connection factories that are configured to use failover provide enhanced reliability by using a group of redundant servers called a failover cluster rather than single server. If a server in the failover cluster is unavailable, the connection factory redirects connection requests to the next server in the failover cluster.

The following code fragment configures a connection factory to use failover:

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 FailoverCluster(servers);
ConnectionFactoryConfiguration cxfConfig = 
   new ManualConnectionFactoryConfiguration(cluster); 

Note:   The connection factory uses the servers in a failover cluster in the order in which they are specified.
