About Course

These standby databases are kept up to date by our Oracle Data Guard as replicas of the production database. Then, if a scheduled or accidental failure renders the production database unavailable, Oracle Data Guard can move any standby database to the production role, minimizing the outage’s associated downtime. To offer a high level of data protection and availability, Oracle Data Guard can be used in conjunction with conventional backup, restore, and cluster procedures. Enrol today to earn your certification.
