Data Guard is basically a ship redo and then apply redo, as you know redo is the information needed to recover a database transaction. A production database referred to as a primary database transmits redo to one or more independent replicas referred to as standby databases. Standby databases are in a continuous state of recovery, validating and applying redo to maintain synchronization with the primary database. A standby database will also automatically resynchronize if it becomes temporary disconnected to the primary due to power outages, network problems, etc.1 person found this helpful
