The Database service offers autonomous and user-managed Oracle Database cloud 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 an autonomous database or user-managed DB system. You have full access to the features and operations available with the database, but Oracle owns and manages the infrastructure.
You can also extend user-managed database services into your data center by using Exadata Cloud at Customer, which applies the combined power of Exadata and Oracle Cloud Infrastructure while enabling you to meet your organization's data-residency requirements.
For details about each offering, start with the following overview topics:

License Types and Bring Your Own License (BYOL) Availability
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 can use existing licenses with Oracle Cloud Infrastructure. Note that Oracle Database customers remain responsible for complying with license restrictions applicable to their BYOL licenses, as defined in their program order for those licenses.
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.
For additional information about license pricing and features, see Oracle Cloud Database Services.
Always Free Database Resources
The Database service is one of the Oracle Cloud Infrastructure services that provides you with Always Free resources as a part of Oracle's Free Tier. For an introduction to the Free Tier, see Oracle Cloud Infrastructure's Free Tier. For details about the Always Free Autonomous Database, see Always Free Availability in the Autonomous Database overview topic. To provision an Always Free Autonomous Database, see To create an Always Free Autonomous Database.
You can move DB systems, Autonomous Database resources, and Exadata Cloud at Customer resources from one compartment to another. When you move a Database resource to a new compartment, its dependent resources move with it. After you move the resource to the new compartment, inherent policies apply immediately and affect access to that resource and its dependent resources through the Console.
To move resources between compartments, resource users must have sufficient access permissions on the compartment that the resource is being moved to, as well as the current compartment. For more information about permissions for Database resources, see Details for the Database Service.
Dependent Resource Details
Details about dependent resources are as follows:
- Bare metal, virtual machine, and Exadata DB systems: Dependent resources that move with these DB systems include Database Homes and databases, as well as the metadata for automatic backups. To verify the compartment of a dependent resource, check the compartment of the DB system.
- Autonomous Database: Autonomous Database dependent resources are limited to its automatic backups. Autonomous Exadata Infrastructure instances and Autonomous Container Databases have no dependent resources that move with them. Associated (non-dependent) resources remain in their current compartments.
- Exadata Cloud at Customer: Resources that can be moved are Exadata Infrastructure, VM clusters, and backup destinations. VM cluster networks are dependent resources of Exadata Infrastructure instances, so they move with them. VM clusters have the following dependent resources: Database Homes, and databases and their automatic backups. Backup destinations have no dependent resources.
For more information about moving resources to other compartments, see Moving Resources to a Different Compartment.
You can monitor the health, capacity, and performance of your Oracle Cloud Infrastructure resources by using metrics, alarms, and notifications. For more information, see Monitoring Overview and Notifications Overview.
For information about available Database service metrics and how to view them, see Database Metrics.
Creating Automation with Events
You can create automation based on state changes for your Oracle Cloud Infrastructure resources by using event types, rules, and actions. For more information, see Overview of Events.
The following Database resources emit events:
Autonomous Database Resources:
- Autonomous Databases
- Autonomous Container Databases
- Autonomous Exadata Infrastructure instances
Exadata Cloud at Customer Resources:
- Exadata Infrastructure
- VM cluster networks
- VM clusters
- Backup destinations
- Database nodes
- Database Homes
Most types of Oracle Cloud Infrastructure resources have 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.
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.
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.
See Service Limits for a list of applicable limits and instructions for requesting a limit increase. To set compartment-specific limits on a resource or resource family, administrators can use compartment quotas.

Many Database API operations are subject to throttling.
The Database service is integrated with the Oracle Cloud Infrastructure Work Requests API. Work requests allow you to monitor long-running operations such as the provisioning of DB systems. A work request is an activity log that enables you to track each step in the operation's progress. Each work request has an An Oracle-assigned unique ID called an Oracle Cloud Identifier (OCID). This ID is included as part of the resource's information in both the Console and API. that allows you to interact with it programmatically and use it for automation. For general information on using work requests in Oracle Cloud Infrastructure, see Work Requests and the Work Requests API.
The following Database operations result in the creation of a work request:
In the Database service, work requests are currently supported only for the Autonomous Database resources in the list that follows.
Creating or terminating the following resource types:
- Autonomous Databases
- Autonomous Container Databases
- Autonomous Exadata Infrastructure instances
- Starting or stopping an Autonomous Database instance
