Progress OpenEdge Connection Failover Properties
Progress OpenEdge Database
Table 6 summarizes the connection properties that control how connection failover works
with the Database Service Progress OpenEdge driver. See “Progress OpenEdge
Connection Properties” on page 139 for details about configuring each property.
Table 6. Connection Failover Properties for the Progress Open Edge Driver
Property Description
AlternateServers List of alternate database servers. An IP address or server name identifying each
server is required. Port number and the DatabaseName connection property are
optional. If the port number is unspecified, the port number specified for the primary
server is used.
ConnectionRetryCount Number of times the driver retries the primary database server, and if specified,
alternate servers until a successful connection is established. The default is 5.
ConnectionRetryDelay Wait interval, in seconds, between connection retry attempts when the
ConnectionRetryCount property is set to a positive integer. The default is 1.
DatabaseName Name of the Progress OpenEdge database server to which you want to connect.
LoadBalancing Sets whether the driver will use client load balancing in its attempts to connect to the
list of database servers (primary and alternate). If client load balancing is enabled,
the driver uses a random pattern instead of a sequential pattern in its attempts to
connect. The default is false (client load balancing is disabled).
PortNumber Port listening for connections on the primary database server. This property is
supported only for DataSource connections. The default port number varies,
depending on operating system.
See “Client Load Balancing” on page 131 and “Connection Failover” on page 132 for
overviews of these features.
