You can also configure security for high availability. You can configure an application server cluster and Adaptive Server in a companion environment to provide high availability in the event that either server goes down.
To configure an EAServer cluster, see the EAServer System Administration Guide, Chapter 6, “Clusters and Synchronization” and Chapter 7, “Load Balancing, Failover, and Component Availability.” To configure Adaptive Server in a companion server architecture, see Adaptive Server Enterprise 12.5, Using Sybase Failover in a High Availability System. Both books are availablehttp://www.sybase.com/support/manuals.
To configure a WebLogic cluster, see your BEA WebLogic documentation.
