3-8 Compaq Parallel Database Cluster Model PDC/O2000 for Oracle8i and Windows 2000 Administrator Guide Application Failover and Reconnection Software When a network client computer operates in a clustered environment, it must be more resilient than when operating with a stand-alone server. Because a client can access the database through any of the cluster nodes, the failure of the connection to a node does not have to prevent the client from reattaching to the cluster and continuing its work. Oracle clustering software provides the capability to allow the automatic reconnection of a client and application failover in the event of a node failure. To implement this application and connection failover, a software interface between the Oracle software and the client must be written. Such a software interface would be responsible for detecting when the client's cluster node is no longer available and then connecting the client to one of the remaining, operational cluster nodes. NOTE: For complete information on how to ensure client auto-reconnect in an Oracle Parallel Server environment, contact your Oracle representative.
