Course Description
Overview
This hands-on course will teach students how to exploit the capabilities of Data Guard (back-ported to earlier releases when necessary) with insight into how best to use the various features. The course provides in-depth coverage of Data Guard for all releases: the current release is used for exercises and demonstrations, and the content back-ported as necessary for previous releases.There is emphasis on Data Guard being more than a zero data loss solution. For example, it can give you performance (Logical Standby), development and testing systems (Snapshot Standby), and is a vital part of distributed Oracle database environments.
Objectives
