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.

Associated specifications in AuDG

Before we can go ahead with enabling AuDG, let’s first understand the following terminologies that are associated with AuDG.

Region and roles specification

In a local AuDG configuration, the values of regions and roles for a primary and standby Autonomous Database do not differ, but the values carry a difference with a cross-region AuDG configuration. AuDG will assign the value for the region as either primary or remote based on its role at the time when you enabled the Autonomous Data Guard option. That is, if the database has the primary role, then the region value would be primary, and if the role is standby, then the region would be remote and this value for the database does not change after a switchover or failover:

  • Primary: This is the region where the primary database or local standby database is provisioned
  • Remote: This is the cross-region where the remote standby is initially created

During a failover or a...
