Oracle Database 19c 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.

Versions supported 19c, 18c, 12c.

The delegate will learn and acquire skills as follows:

 

  • Preparing a Primary Database for a Data Guard Configuration
  • Creating a Physical Standby Database
  • Creating a Logical Standby Database
  • Creating a Snapshot Standby Database
  • Monitoring a Standby Database Configuration
  • Managing a Data Guard Configuration
  • Troubleshooting Standby Database Configurations
  • Tuning a Standby Database
  • Backing up and Recovering a Data Guard Configuration
  • Using Flashback in a Data Guard Configuration
  • Using the Data Guard Broker
  • Managing a Configuration using the Broker
  • Overview of Patching and Upgrading

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

Who will the Course Benefit?

The Oracle Database 19c Data Guard course is designed for database administrators and technical support staff who are required to plan and implement Oracle Data Guard configurations.

Course Objectives

This course aims to provide the delegate with the knowledge to be able to plan, implement, manage and troubleshoot Oracle Data Guard standby database configurations.

Requirements

A working knowledge of Oracle Database Administration is required, these skills can be obtained by attendance on the pre-requisite Oracle Administration and Oracle Database Backup and Recovery with RMAN courses.

This course is run on a Linux operating system and a good working knowledge of Linux/UNIX is required. This knowledge can be gained by attendance on the pre-requisite Linux Introduction course.

Where Oracle 18c courses are listed in the Pre-requisite Courses section equivalent Oracle 11g or Oracle 12c courses would also suffice.
