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.

Scale Up/Down

By default, the autonomous database will be created with 1 OCPU and 1 TB of storage. However, it can be scaled up or down either manually or automatically. On the Autonomous Database Information page, click the Scale Up/Down button.

Figure 6.21 – Scale Up/Down

It will take you to the Scale Up/Down window, as shown in Figure 6.22.

Figure 6.22 –Scale Up/Down details

We can choose the required OCPU count and the amount of storage in TB. We also have the option to specify Auto Scaling. CPU scaling doesn’t require downtime, and the billing will be calculated on average OCPU usage per hour.

Auto Scaling is enabled by default, and it will scale up three times the current CPU base number. If the base number is 1 OCPU, then auto scaling will scale up the OCPU count to 3, which continues as demand increases. In the same way, scaling down will happen when demand decreases.
