Oracle Autonomous Database in Enterprise Architecture

By: Bal Mukund Sharma, Krishnakumar KM, Rashmi Panda

Overview of this book

Oracle Autonomous Database (ADB) is built on the world’s fastest Oracle Database Platform, Exadata, and is delivered on Oracle Cloud Infrastructure (OCI), customer data center (ExaCC), and Oracle Dedicated Region Cloud. This book is a fast-paced, hands-on introduction to the most important aspects of OCI Autonomous Databases. You'll get to grips with concepts needed for designing disaster recovery using standby database deployment for Autonomous Databases. As you progress, you'll understand how you can take advantage of automatic backup and restore. The concluding chapters will cover topics such as the security aspects of databases to help you learn about managing Autonomous Databases, along with exploring the features of Autonomous Database security such as Data Safe and customer-managed keys for Vaults. By the end of this Oracle book, you’ll be able to build and deploy an Autonomous Database in OCI, migrate databases to ADB, comfortably set up additional high-availability features such as Autonomous Data Guard, and understand end-to-end operations with ADBs.

Understanding the backup types

In an autonomous environment, all DB tasks are managed automatically; in the same way, the backup will also be taken care of by itself. But we do have a provision to back up the data manually. Let’s discuss both methods.

Working with automated backup in the OCI portal

Automated backup is configured by default when we create an autonomous database. It is a mandatory backup taken daily for autonomous databases. No manual effort is required in this backup method.

Figure 5.1 – Automatic backup list

In general, an Oracle database has various methods to take backups. RMAN is one of the proven methods to take Oracle database backup. This method has the luxury of taking a backup of either the full database or only changes that happened after the last full backup (incremental backup). Also, it has features to validate the backup before Restore. In an autonomous environment, the automated database backup takes RMAN full...
