Course Description

This Oracle Database 19c Backup and Recovery with RMAN course is designed to give an Oracle database administrator practical experience in planning and implementing a backup and recovery strategy using Recovery Manager and Flashback Database. The delegate will learn how to perform backup and recovery operations using RMAN and will learn how to use Flashback features to recover from human error.

Similarly, the course is targeted to closely follow the official Oracle Database curriculum for certification.

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

Versions supported 12cR2, 18c, 19c.

Target Student

The Oracle Database 19c Backup and Recovery with RMAN course is designed for database administrators, data warehouse administrators and technical support staff who are required to plan and implement database backup and recovery strategies for Oracle databases.

Pre-requisites

A working knowledge of Oracle SQL and Oracle Database Administration is required to attend the Oracle Database 19c Backup and Recovery with RMAN course. This can be obtained by attendance on the Oracle SQL course and a suitable database administration course. The ability to describe and use Oracle built-in packages would be advantageous, but is not essential.

This course is run on a Linux operating system, a basic knowledge of UNIX/Linux is recommended but is not essential.

Where Oracle 19c or 18c courses are listed in the Pre-requisite Courses section equivalent Oracle 12c courses would also suffice.

Course Objectives

The Oracle Database 19c Backup and Recovery with RMAN course is designed to provide the skills needed to enable a delegate to plan and implement a backup and recovery strategy in the workplace for Oracle Databases using RMAN and Flashback Database technologies.
