Connection information for primary and alternate servers can be specified using either a connection URL through the JDBC Driver Manager or a JDBC data source. For example, the following connection URL for the Progress OpenEdge driver specifies connection information for the primary and alternate servers using a connection URL:

jdbc:datadirect:openedge://server1:2003;HostName=TestServer;
DatabaseName=TestServer;User=test;Password=secret;
AlternateServers=(server2:2003;server3:2003)

In this example:

...server1:2003;DatabaseName=TestServer...

is the part of the connection URL that specifies connection information for the primary server. Alternate servers are specified using the AlternateServers property. For example:

...;AlternateServers=(server2:2003;server3:2003)

Similarly, connection information for the primary server specified using a JDBC data source would look something like this:

OpenEdgeDataSource mds = new OpenEdgeDataSource();
mds.setDescription("My OpenEdgeDataSource");
mds.setServerName("server1");
mds.setPortNumber(2003);
mds.setDatabaseName("TestServer");
mds.setUser("test");
mds.setPassword("secret");mds.setAlternateServers=("server2:2003;server3:2003")

In this example, connection information for the primary server is specified using the ServerName, PortNumber, and DatabaseName properties. Connection information for alternate servers is specified using the AlternateServers property.
