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. Data Guard maintains these standby databases as transactionally consistent copies of the production database. In this course you will learn how to use Oracle Data Guard to protect their Oracle database against planned and unplanned downtimes. You will also get to know how to use Data Guard standby databases to support production functions such as reporting, querying and testing.
