Replication Server’s warm standby application is described in detail in Chapter 3, “Managing Warm Standby Applications,” in the Replication Server Administration Guide Volume 2.
Replication Server version 12.0 and later supports Sybase Failover available in Adaptive Server Enterprise version 12.0. Failover support is not a substitute for warm standby. While warm standby applications keep a copy of a database, Failover support accesses the same database from a different machine. Connections from Replication Server to warm standby databases work the same way.
For detailed information about how Failover support works in Replication Server, see “Configuring the Replication System to Support Sybase Failover” in Chapter 7, “Replication System Recovery,” and Appendix B, “High Availability on Sun Cluster 2.2,” in the Replication Server Administration Guide Volume 2.
