Chapter 6: Driver Connection Properties and Data Types by Database Brand
is the part of the connection URL that specifies connection information for the primary
server. Alternate servers are specified using the AlternateServers property, in this
example:
...;AlternateServers=(server2:1433;DatabaseName=TEST2,server3:1433;
DatabaseName=TEST3)
You can specify an optional instance property for each alternate server entry. For
example:
jdbc:progress:sqlserver://server1:1433;DatabaseName=TEST;
AlternateServers=(server2:1433;DatabaseName=TEST2,server3:1433;
DatabaseName=TEST3)
or, if connecting to named instances:
jdbc:progress:sqlserver://server1\\instance1:1433;DatabaseName=TEST;
AlternateServers=(server2\\instance2:1433;DatabaseName=TEST2,
server3\\instance3:1433;DatabaseName=TEST3)
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 the primary
server. For example, if you specify DatabaseName=TestServer for the primary server, but
do not specify the InformixServer and DatabaseName properties in the alternate server
entry as shown in the following URL, the driver uses the InformixServer and
DatabaseName specified for the primary server and tries to connect to the TEST database on
the alternate server:
jdbc:progress:sqlserver://server1:1433;DatabaseName=TEST;
AlternateServers=(server2:1433,server3:1433)
The SQL Server driver also allows you to specify connections to named instances,
multiple instances of a Microsoft SQL Server database running concurrently on the same
server. If specifying named instances for the primary and alternate servers, the connection
URL would look like this:
jdbc:progress:sqlserver://server1\\instance1;
AlternateServers=(server2\\instance2:1433;DatabaseName=TEST2,
server3\\instance3:1433;DatabaseName=TEST3)
