# Entitlement sharing in Oracle Database@AWS
<a name="entitlement-sharing"></a>

With Oracle Database@AWS, you can share AWS Marketplace entitlements for Oracle Database@AWS across AWS accounts in the same AWS organization. This allows other accounts to provision their own Oracle Exadata infrastructure and ODB network resources using your subscription.

## Sharing methods
<a name="sharing-methods"></a>

Oracle Database@AWS supports two methods for sharing:

### Entitlement sharing with AWS License Manager
<a name="entitlement-sharing-method"></a>
+ Grant other accounts the ability to provision their own Oracle Exadata infrastructure and ODB network resources
+ Each account operates independently with full resource lifecycle control
+ Best for enabling self-service provisioning across teams or business units

### Resource sharing with AWS Resource Access Manager (AWS RAM)
<a name="ram-sharing-method"></a>
+ Share already provisioned Oracle Exadata infrastructure and ODB network resources
+ Centralize infrastructure management while allowing recipient accounts to create VM clusters
+ Optimize costs by having multiple accounts use the same infrastructure

You can use both sharing methods simultaneously based on your organizational needs.

To enable collaboration while optimizing costs, share Oracle Database@AWS entitlements with other AWS accounts within the same AWS organization. This topic explains how to share entitlements using AWS License Manager.

Before you share Oracle Database@AWS entitlements, make sure that you have the following:
+ An active Oracle Database@AWS subscription (you must be the buyer account that accepted the private offer through AWS Marketplace)
+ The IDs of the AWS accounts in your organization that you want to share entitlements with
+ Necessary permissions for grantor and grantee to use AWS License Manager resources and operations (for more information, see [Identity and access management for License Manager](https://docs.aws.amazon.com/license-manager/latest/userguide/identity-access-management.html) in the *AWS License Manager User Guide*)
+ Permissions listed below for you (grantor) and entitlement recipient (grantee)

## Permissions required for entitlement sharing

In addition to AWS License Manager permissions, Oracle Database@AWS requires the following permissions:

### Grantor permissions
<a name="sharing-entitlements-permissions-grantor"></a>
+ `odb:CreateGrantShare`
+ `odb:UpdateGrantShare`
+ `odb:DeleteGrantShare`

## Sharing Oracle Database@AWS entitlements with another account using AWS License Manager
<a name="sharing-entitlements"></a>

To share entitlements with another AWS account, you create a grant using AWS License Manager. For more information, see [Distribute License Manager entitlements](https://docs.aws.amazon.com/license-manager/latest/userguide/distribute-entitlement.html) in the *AWS License Manager User Guide*.

After you create the grant, the recipient (grantee) must:
+ Accept and activate the grant. For more information, see [ Grant acceptance and activation in License Manager](https://docs.aws.amazon.com/license-manager/latest/userguide/grant-acceptance.html) in the *AWS License Manager User Guide*.
+ Follow the [initialization instructions](https://docs.aws.amazon.com/odb/latest/UserGuide/initialize-service-task.html#initialize-service-overview) for Oracle Database@AWS.

After initialization completes, the grantee can provision Oracle Database@AWS resources using the shared entitlement.
