Replica Instance

A replica instance provides deployment-level redundancy of the primary instance. With a few exceptions, you can view, but not update, administrative data on a replica instance.

A replica instance provides the following benefits:

  • Real-time mirror of all user and system data

  • Failover authentication if the primary instance becomes unresponsive

  • Improved performance by load balancing authentication requests to multiple instances

  • Ability to deploy a replica instance at a remote location

  • Ability to recover administrative capabilities through replica promotion if the primary instance becomes unresponsive

  • Administrators can clear PINs and provide emergency access to users

    Note: If the primary instance has an “Out-of-Sync” replication status, for any reason, resynchronizing the deployment removes any administrative changes that occurred on a replica instance. For example, you may need to regenerate an offline emergency access tokencode that was generated on a replica instance.

Although a replica instance is optional, RSA recommends that you deploy both a primary and a replica instance. The RSA Authentication Manager Base Server license and the Enterprise Server license both include permission to deploy a replica instance.
