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.

Operating system access restriction

Usually, in a database environment, the database administrator (DBA) accesses the server to install and manage the database. They will create the necessary data files and then load the data into the database. DBAs and system administrators also access the servers to perform day-to-day maintenance tasks, such as database backup generation, archive logs generation, data files growth, and rectifying physical corruption. They also access the operating system structure to perform the scaling of the CPU, memory, and storage. Here, in the Autonomous Database, the provisioning and management are automated. All database management tasks are taken care of automatically. Hence, Autonomous Database only provides database connectivity. The underlying operating system is not accessible from the outside. We can’t connect the database server via SSH. The Autonomous Database server is secured and managed by Oracle.
