In a warm standby application, the active database and the standby database appear in the replication system as a connection from the Replication Server to a single logical database. The replication system administrator creates this logical connection to establish one symbolic name for both the active and standby databases.
Thus, a warm standby application involves three database connections from the Replication Server:
A physical connection for the active database
A physical connection for the standby database
A logical connection for the active and standby databases
Replication Server maps the logical connection to the currently active database and copies transactions from the active to the standby database.
See “Setting up warm standby databases” for details on creating the logical and physical database connections. See Chapter 7, “Managing Database Connections” in the Replication Server Administration Guide Volume 1 for more information about physical database connections.
