This course is aimed at:

The Oracle Database 18c Data Guard course is designed for database administrators and technical support staff who are required to plan and implement Oracle Data Guard configurations.

You will need:

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.

You will learn to:

  • 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
