DataDirect Connect Drivers : Progress OpenEdge Driver : Connection Failover Properties
  
Connection Failover Properties
The following table summarizes the connection properties that control how connection failover works with the Progress OpenEdge driver. See Connection Properties for details about configuring each property.
Table 61. Connection Failover Properties for the Progress OpenEdge Driver
Property
Characteristic
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 database to which you want to connect.
HostName
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 Using Failover and Using Client Load Balancing for overviews of failover and client load balancing.
