Configuring Connection Failover and Client Load Balancing for the ADO Client

Note: The ADO and ADO.NET clients are currently available only in OpenAccess SDK 8.1. However, they are compatible with the OpenAccess SDK 9.0 server.

The ADO Client can help you make sure that your critical data is available even if the primary database server is unavailable:

• Connection failover allows an application to connect to an alternate, or backup, database server if the primary database server is unavailable, for example, because of a hardware failure or traffic overload. See Using Connection Failover for more information.
• Connection retry defines the number of times the driver attempts to connect to the primary server and, if configured, alternate database servers after the initial unsuccessful connection attempt. See Using Connection Retry for more information.
• Client load balancing helps distribute new connections in your environment so that no one server is overwhelmed with connection requests. See Using Client Load Balancing for more information.
