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. This book will be an exception to the rule and will become a must-have reference, allowing you to design a real and complete backup and recovery strategy. 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. "Oracle Database 12c Backup and Recovery Survival Guide" contains everything a DBA needs to know to keep data safe and recoverable, using real-life scenarios.

Configuring encrypted backups


As necessary as it is to ensure that backups (and restores) are performed without spending much time, making these backups secure is also very important. You may ask why and the answer is that if someone gets their hands on the backup of a database, creating a duplicate database from it wouldn't be very tough. That's the reason why backups must be encrypted, to prevent such indirect stealing of databases. As you may have guessed already, RMAN can certainly do this.

From Version 10.2 onwards, RMAN has the option of creating the encrypted backups which will be decrypted during the restore and recover operations. To do so, the decryption keys are required which are stored individually within every backup piece. Also, for each backup set, there will be a separate key generated.

To perform encryption, you need to enable the option using the command CONFIGURE ENCRYPTION FOR DATABASE ON.

There are three modes which are available for encryption:

  • Transparent encryption

  • Password...
