Oracle Database 12cR2 Data Guard [STA_O12CDG]

OVERVIEW

Oracle Database 12cR2 Data Guard Course Overview

This course introduces the main architectural concepts of Oracle Data Guard. The delegate will learn how to use Oracle Data Guard to protect an Oracle Database against planned and unplanned downtime.

The delegate will also learn how to create and manage physical,logical and snapshot standby databases and how to use standby databases for reporting,querying and testing purposes.

Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.

Versions supported 12cR2,18c,19c.
