Chapter 5: Using the Database Service JDBC Drivers
Connection Retry Example for Sybase Driver
jdbc:progress:sybase://server1:4100;DatabaseName=TEST;
AlternateServers=(server2:4100;DatabaseName=TEST2,
server3:4100;DatabaseName=TEST3);ConnectionRetryCount=2;
ConnectionRetryDelay=5
Specifying Primary and Alternate Servers
The Sonic Database Service JDBC drivers allow you to specify a list of alternate database
servers that are tried at connection time if the primary server is not accepting connections
using the AlternateServers property. Connection attempts continue until a connection is
successfully established or until all the database servers (primary and alternate) have been
tried the specified number of times.
Connection information for alternate servers is specified using the AlternateServers
property in a connection URL. 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 of the 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. Port numbers are optional for each alternate server entry. If unspecified, the port
number specified for the primary server is used. If a port number is unspecified for
the primary server, the default port number is used (see Table 4 on page 130 to locate
the appendix containing information on the default PortNumber values for the JDBC
drivers).
● property=value is an optional connection property, based on the JDBC driver to
which you are connecting.
