Switch Clients to the New Database

Switching from the active to the standby database does not switch client applications to the new active data server and database.

You must devise a method to handle client switching. For example, you could:

Set up two interfaces files, one for client applications and one for Replication Server. At switch time, modify the client interfaces file to point to the new active server.
Create an interfaces file entry with a symbolic data server name for use by client applications. At switch time, modify the address information associated with the symbolic name.
Use a mechanism, such as an intermediate Open Server, to map the client application data server connections to the currently active data server automatically.

See the Replication Server Administration Guide Volume 2.
