Oracle Database Tablespace Encryption Behavior in Oracle Cloud (Doc ID 2359020.1)

Last updated on AUGUST 09, 2023

Applies to:

Gen 1 Exadata Cloud at Customer (Oracle Exadata Database Cloud Machine)
Gen 2 Exadata Cloud at Customer
Oracle Cloud Infrastructure - Exadata Cloud Service
Oracle Cloud Infrastructure - Database Service
Linux x86-64 on Oracle Public Cloud

Purpose

The purpose of this document is to describe the behavior of Transparent Data Encryption in an Oracle Cloud environment.

Oracle Database Cloud Services, including Exadata Cloud Service and Cloud@Customer, require TDE Encryption be enabled for all tablespaces by policy.

Scope

This document describes how Oracle Database Tablespace Encryption works for the following use cases:

New tablespaces created in a Database deployed in Cloud
Tablespaces that have been migrated to Cloud from an on-premises Database
Tablespaces in a standby database in Cloud with its corresponding primary database located on-premises (i.e. a Hybrid DR configuration)

Applies to Oracle Database Cloud Services including Base Database Service, Exadata Database on Dedicated Infrastructure and Exadata Database on Cloud@Customer. For Autonomous Database Cloud services, all database data is always encrypted.
