Warm Standby

A warm standby application is a pair of databases, one of which is a backup copy of the other. Client applications update the active database; Replication Server maintains the standby database as a copy of the active database.

The Replication Server warm standby application for Adaptive Server databases is described in the Replication Server Administration Guide Volume 2 > Managing Warm Standby Applications.

Note: 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 Replication Server Administration Guide Volume 2 > Configuring the Replication System to Support Sybase Failover and Replication Server Administration Guide Volume 2 > High Availability on Sun Cluster 2.2.
