Oracle Database 12c Backup and Recovery Survival Guide

Overview of this book

The three main responsibilities of a successful DBA are to ensure the availability, recoverability, and performance of any database. To ensure the recoverability of any database, a DBA needs to have a strong backup and recovery skills set. Every DBA is always looking for a reference book that will help them to solve any possible backup and recovery situation that they can come across in their professional life. Oracle Database 12c Backup and Recovery Survival Guide has the unique advantage to be a reference to all Oracle backup and recovery options available, making it essential for any DBA in the world. If you are new to Oracle Database, this book will introduce you to the fantastic world of backup and recovery that is vital to your success. If you are an experienced DBA, this book will become a reference guide and will also help you to learn some possible new skills, or give you some new ideas you were never aware about. It will also help you to easily find the solution to some of the most well known problems you could find during your career as a DBA. This book contains useful screenshots, scripts, and examples that you will find more than useful. Most of the books currently available in the market concentrate only on the RMAN utility to backup and recovery.

It covers the most important topics on Oracle database such as backup strategies, Nologging operations, new features in 12c, user managed backups and recoveries, RMAN (including reporting, catalog management, troubleshooting, and performance tuning), advanced data pump, Oracle Enterprise Manager 12c and SQL Developer.

Using SOURCE_EDITION and TARGET_EDITIONS


With the introduction in Oracle 11gR2 of editions (Edition-Based Redefinition) that allow us to play with different versions (editions) of an object in an Oracle Database, Data Pump was forced to introduce new parameters to allow us to work within different editions available in the database. The parameters introduced were:

  • SOURCE_EDITION to be used within expdp

  • TARGET_EDITIONS to be used within impdp

A good example of the use of these new parameters is when we have multiple versions (editions) of an object in our development environment for different releases of an application, and we want to migrate a code from one version to a different version within a database or even across multiple databases.

In the following example, we will migrate a view (from our development database) called TEST from the schema TEST in the edition called NEW_EDITION to our production database schema TEST and to the edition called ORA$BASE:
