A high availability cluster includes two machines that are configured so that, if one machine (or application) is brought down, the second machine assumes the workload of both machines. Each of these machines is called a node of the high-availability cluster. A high-availability cluster is typically used in an environment that must always be continuously available.
Sybase’s Failover feature is documented in the Adaptive Server Enterprise Using Sybase Failover in a High Availability System manual. This section contains information necessary to configure your Open Client applications to connect to the secondary companion during failover.
