Oracle Data Guard
Oracle Data Guard ensures high availability, data protection, and disaster recovery for enterprise data. Data Guard provides a comprehensive set of services that create, maintain, manage, and monitor one or more standby databases to enable production Oracle databases to survive disasters and data corruptions.
Oracle Data Guard course makes a note on protection of Oracle database against planned and unplanned downtimes to support production functions such as reporting, querying, and testing, while still in the standby role. The course curricula include:
