Oracle Cloud Infrastructure Documentation

Overview of the Database Service

The Database service offers autonomous and user-managed Oracle Database solutions. Autonomous databases are preconfigured, fully-managed environments that are suitable for either transaction processing or for data warehouse workloads. User-managed solutions are bare metal, virtual machine, and Exadata DB systems that you can customize with the resources and settings that meet your needs.

You can quickly provision a user-managed DB system or autonomous database. You have full access to the features and operations available with the database, but Oracle owns and manages the infrastructure.

For details about each offering, start with the following overview topics:

License Types

Oracle Cloud Infrastructure supports a licensing model with two license types. With License included, the cost of the cloud service includes a license for the Database service. With Bring Your Own License (BYOL), Oracle Database customers with an Unlimited License Agreement or Non-Unlimited License Agreement can use their license with Oracle Cloud Infrastructure. You do not need separate on-premises licenses and cloud licenses. BYOL databases support all advanced Database service manageability functionality, including backing up and restoring a DB system, patching, and Oracle Data Guard.

You can choose BYOL when you launch an Oracle Cloud Infrastructure database or DB system. Choosing BYOL impacts how the usage data for the instance is metered and subsequent billing.

Note that on some provisioning dialogs in the Console, the BYOL option is labeled My Organization Already Owns Oracle Database Software Licenses.

Bring Your Own License (BYOL) Availability

For all database versions, the Database service allows you to bring your existing database software licenses to the database cloud service when provisioning the following products:

  • Bare Metal Shapes: BM.DenseIO1.36 and BM.DenseIO2.52
  • Virtual Machine Shapes:

    • VM.Standard2 (X7 with remote storage): 1, 2, 4, 8, 16, and 24 core
    • VM.Standard1 (X5 with remote storage): 1, 2, 4, 8, and 16 core.


      X5-based shapes availability is limited to monthly universal credit customers existing on or before November 9th, 2018, in the us-phoenix-1, us-ashburn-1, and eu-frankfurt-1 regions.

  • Exadata X7 and X6 Shapes: Quarter, Half, and Full racks
  • Autonomous Transaction Processing Databases
  • Autonomous Data Warehouse Databases

Some restrictions apply:

  • If you choose to use your existing database software licenses (BYOL), you cannot switch between the BYOL and license-included licensing model on the same database instance. Instead, you have to terminate and then recreate the database.
  • The Database service supports using your existing database software licenses (BYOL) only for customers who use the Universal Credit Plan. Non-metered customers cannot use existing database software licenses. Existing customers can migrate from a non-metered model to a Universal Credit Plan.
  • You can only use the options you purchased as part of your ULA.
  • If you have Standard or Enterprise Licenses with additional options, you need to use a Standard Edition or Enterprise Edition license.
  • If you have any additional database option other than RAC, Active Data Guard, Database In-Memory, or Multitenant, you need to use Enterprise Edition - High Performance.
  • If you have Active Data Guard, Database In-Memory, or Multitenant, you need to use Enterprise Edition - Extreme Performance. If you choose the Extreme Performance edition for a 2-node RAC on virtual machine configuration, then the additional OCPUs will be charged at the RAC OCPU pricing.

Resource Identifiers

Each Oracle Cloud Infrastructure resource has a unique, Oracle-assigned identifier called an Oracle Cloud ID (OCID). For information about the OCID format and other ways to identify your resources, see Resource Identifiers.

Ways to Access Oracle Cloud Infrastructure

You can access Oracle Cloud Infrastructure using the Console (a browser-based interface) or the REST API. Instructions for the Console and API are included in topics throughout this guide. For a list of available SDKs, see Software Development Kits and Command Line Interface.

To access the Console, you must use a supported browser. You can use the Console link at the top of this page to go to the sign-in page. You will be prompted to enter your cloud tenant, your user name, and your password.

For more information, see compartments and tenancy. For general information about using the API, see REST APIs.

If you're new to policies, see Getting Started with Policies and Common Policies. If you want to write policies that provide stricter access to database resources, see Details for the Database Service.

Authentication and Authorization

Each service in Oracle Cloud Infrastructure integrates with IAM for authentication and authorization, for all interfaces (the Console, SDK or CLI, and REST API).

An administrator in your organization needs to set up A collection of users who all need a particular type of access to a set of resources or compartment., A collection of related resources that can be accessed only by certain groups that have been given permission by an administrator in your organization., and An IAM document that specifies who has what type of access to your resources. It is used in different ways: to mean an individual statement written in the policy language; to mean a collection of statements in a single, named "policy" document (which has an Oracle Cloud ID (OCID) assigned to it); and to mean the overall body of policies your organization uses to control access to resources. that control which users can access which services, which resources, and the type of access. For example, the policies control who can create new users, create and manage the cloud network, launch instances, create buckets, download objects, etc. For more information, see Getting Started with Policies. For specific details about writing policies for each of the different services, see Policy Reference.

If you’re a regular user (not an administrator) who needs to use the Oracle Cloud Infrastructure resources that your company owns, contact your administrator to set up a user ID for you. The administrator can confirm which compartment or compartments you should be using.

For common policies used to authorize Oracle Cloud Infrastructure Database users, see Common Policies.

For in-depth information on granting users permissions for the Database service, see Details for the Database Service in the IAM policy reference.

Limits on the Database Service

See Service Limits for a list of applicable limits and instructions for requesting a limit increase.

Many Database API operations are subject to throttling.
