Using the AlternateServers Property
Progress OpenEdge Database
Connection information for alternate servers is specified using the AlternateServers
property with either a connection URL through the JDBC Driver Manager or a JDBC data
source. The value of the AlternateServers property is a string that has the format:
(servername1[:port1][;property=value[;...]],servername2[:port2]
[;property=value[;...]],...)
where:
servername1 is the IP address or server name of the first alternate database server,
servername2 is the IP address or server name ofthe second alternate database server, and
so on. The IP address or server name is required for each alternate server entry.
port1 is the port number on which the first alternate database server is listening, port2 is
the port number on which the second alternate database server is listening, and so on. The
port number is optional for each alternate server entry. If unspecified, the port number
specified for the primary server is used.
property=value is either of the following connection properties: DatabaseName or
HostName. These connection properties are optional for each alternate server entry.
For example:
jdbc:datadirect:openedge://server1:2003;HostName=TestServer;
DatabaseName=TestServer;User=test;Password=secret;
AlternateServers=(server2:2003;HostName=TestServer2;
DatabaseName=TestServer,server3:2003)
If you do not specify an optional connection property in an alternate server entry, the
connection to that alternate server uses the property specified in the URL. For example, if
youspecify HostName=TestServer and DatabaseName=TestServer for the primary server,
but do not specify the HostName and DatabaseName properties in the alternate server
entry as shown in the following URL, the driver uses the HostName and DatabaseName
specified for the primary server and tries to connect to the TestServer database on the
Progress OpenEdge server TestServer:
jdbc:datadirect:openedge://server1:2003;HostName=TestServer;
DatabaseName=TestServer;AlternateServers=(server2:2003,server3:2003)
