Vhisper provides Warm Standby capabilities to a Versant Object Database. The add-on module is used as an incremental rollforward recovery. It is designed to minimize the downtime in an emergency event.
With Vhisper, an up-to-date copy of the primary database is maintained - this is a Warm Standby database. In case of an emergency, the Vhisper's Warm Standby database can be updated very quickly to the state of the primary database. Instead of starting a full database restore that may take a considerable time with large databases, you just need to apply the last roll forward archive plus the logical.log of the primary database to the Warm Standby database – and you are ready for anything.
The Vhisper add-on module requires separate licensing.
