Deployment Example: Single Sign-On, Load Balancing and Failover Using Sun OpenSSO Enterprise 8.0

10.1 Session Failover Architecture

When session failover is implemented for OpenSSO Enterprise, session information is replicated in two backend session store databases. This ensures that if one OpenSSO Enterprise server fails or stops, the information stored in the backend session databases can be used to keep the user continuously authenticated. If session failover is not implemented and the OpenSSO Enterprise server in which a user's session was created fails, the user will have to reauthenticate to perform an operation that requires a session token.

Note –

For more information about OpenSSO Enterprise and session failover, see Chapter 7, Implementing OpenSSO Enterprise Session Failover, in Sun OpenSSO Enterprise 8.0 Installation and Configuration Guide.
