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.

Manual database backup using Data Pump

Data Pump is a powerful tool to take logical backup and it has been introduced in Oracle Database 10g. It extracts the user data with its metadata and generates a dump file. That dump file can be imported into the target database. In general, it is a server-side utility, which means the dump will get stored in the database server. In an autonomous environment, we won’t get server access, so how we will take a backup? The answer is either to create an autonomous dump set and then move it to object storage, or directly take the dump to object storage. We will discuss both methods here.

Creating a dump set

The step for creating a dump set is similar to the on-premises environment. First, we need to create a logical directory at the database level to store the dump:

SQL>  create directory dump_dir as 'datapump_dir';
Directory created.
SQL> select directory_name , directory_path from dba_directories;
