# Amazon RDS for Db2 licensing options Amazon RDS for Db2 has two licensing options: bring your own license (BYOL) and Db2 license through Amazon Web Services Marketplace. **Topics** + [Bring your own license (BYOL) for Db2](#db2-licensing-options-byol) + [Db2 license through Amazon Web Services Marketplace](#db2-licensing-options-marketplace) + [Switching between Db2 licenses](#db2-edition-license-switching) ## Bring your own license (BYOL) for Db2 In the BYOL model, you use your existing Db2 database licenses to deploy databases on Amazon RDS. Verify that you have the appropriate Db2 database license for the DB instance class and Db2 database edition that you want to run. You must also follow IBM policies for licensing IBM database software in the cloud computing environment. **Note** Multi-AZ DB instances are cold standbys because the Db2 database is installed but not running. Standbys aren't readable, running, or serving requests. For more information, see [IBM Db2 licensing information]( https://www.ibm.com/support/customer/csol/terms/licenses#license-search) on the IBM website. In this model, you continue to use your active IBM support account, and you contact IBM directly for Db2 database service requests. If you have an Amazon Web Services Support account with case support, you can contact Amazon Web Services Support for Amazon RDS issues. Amazon Web Services and IBM have a multi-vendor support process for cases that require assistance from both organizations. Amazon RDS supports the BYOL model for Db2 Standard Edition and Db2 Advanced Edition. **Topics** + [IBM IDs for bring your own license (BYOL) for Db2](#db2-prereqs-ibm-info) + [Adding IBM IDs to a parameter group for RDS for Db2 DB instances](#db2-licensing-options-byol-adding-ids) + [Integrating with Amazon License Manager](#db2-lms-integration) ### IBM IDs for bring your own license (BYOL) for Db2 In the BYOL model, you need your IBM Customer ID and your IBM Site ID to create, modify, or restore RDS for Db2 DB instances. You must create a custom parameter group with your IBM Customer ID and your IBM Site ID *before* you create an RDS for Db2 DB instance. For more information, see [Adding IBM IDs to a parameter group for RDS for Db2 DB instances](#db2-licensing-options-byol-adding-ids). You can run multiple RDS for Db2 DB instances with different IBM Customer IDs and IBM Site IDs in the same Amazon Web Services account or Amazon Web Services Region. **Important** If we can't verify your license by your IBM Customer ID and your IBM Site ID, we might terminate any DB instances running with these unverified licenses. If you're a new IBM Db2 customer, you must first purchase a Db2 software license from [https://www.ibm.com/products/db2/pricing](https://www.ibm.com/products/db2/pricing). After you purchase a Db2 software license, you will receive a Proof of Entitlement from IBM, which lists your IBM Customer ID and your IBM Site ID. If you're an existing IBM Db2 customer, you can find your IBM Customer ID and your IBM Site ID on your Proof of Entitlement certificate from IBM. You can also find your IBM Customer ID and your IBM Site ID in your [IBM Passport Advantage Online](https://www.ibm.com/software/passportadvantage/pao_customer.html) account. After your log in, you can view both IDs on either the main page or the Software downloads page. ### Adding IBM IDs to a parameter group for RDS for Db2 DB instances Because you can't modify default parameter groups, you must create a custom parameter group and then modify it to include the values for your IBM Customer ID and your IBM Site ID. For information about parameter groups, see [DB parameter groups for Amazon RDS DB instances](USER_WorkingWithDBInstanceParamGroups.md). **Important** You must create a custom parameter group with your IBM Customer ID and your IBM Site ID *before* you create an RDS for Db2 DB instance. Use the parameter settings in the following table. | Parameter | Value | | --- | --- | | `rds.ibm_customer_id` | `` | | `rds.ibm_site_id` | `` | | `ApplyMethod` | `immediate`, `pending-reboot` | These parameters are dynamic, which means that any changes to them take effect immediately and that you don't need to reboot the DB instance. If you don't want the changes to take effect immediately, you can set `ApplyMethod` to `pending-reboot` and schedule these changes to be made during a maintenance window. You can create and modify a custom parameter group by using the Amazon Web Services Management Console, the Amazon CLI, or the Amazon RDS API. #### Console **To add your IBM Customer ID and your IBM Site ID to a parameter group** 1. Create a new DB parameter group. For more information about creating a DB parameter group, see [Creating a DB parameter group in Amazon RDS](USER_WorkingWithParamGroups.Creating.md). 1. Modify the parameter group that you created. For more information about modifying a parameter group, see [Modifying parameters in a DB parameter group in Amazon RDS](USER_WorkingWithParamGroups.Modifying.md). #### Amazon CLI **To add your IBM Customer ID and your IBM Site ID to a parameter group** 1. Create a custom parameter group by running the [https://docs.amazonaws.cn/cli/latest/reference/rds/create-db-parameter-group.html](https://docs.amazonaws.cn/cli/latest/reference/rds/create-db-parameter-group.html) command. Include the following required options: + `--db-parameter-group-name` – A name for the parameter group that you are creating. + `--db-parameter-group-family` – The Db2 engine edition and major version. Valid values: `db2-se-11.5`, `db2-ae-11.5`. + `--description` – A description for this parameter group. For more information about creating a DB parameter group, see [Creating a DB parameter group in Amazon RDS](USER_WorkingWithParamGroups.Creating.md). 1. Modify the parameters in the custom parameter group that you created by running the [https://docs.amazonaws.cn/cli/latest/reference/rds/modify-db-parameter-group.html](https://docs.amazonaws.cn/cli/latest/reference/rds/modify-db-parameter-group.html) command. Include the following required options: + `--db-parameter-group-name` – The name of the parameter group that you created. + `--parameters` – An array of parameter names, values, and the application methods for the parameter update. For more information about modifying a parameter group, see [Modifying parameters in a DB parameter group in Amazon RDS](USER_WorkingWithParamGroups.Modifying.md). #### RDS API **To add your IBM Customer ID and your IBM Site ID to a parameter group** 1. Create a custom DB parameter group by using the Amazon RDS API [https://docs.amazonaws.cn/AmazonRDS/latest/APIReference/API_CreateDBParameterGroup.html](https://docs.amazonaws.cn/AmazonRDS/latest/APIReference/API_CreateDBParameterGroup.html) operation. Include the following required parameters: + `DBParameterGroupName` + `DBParameterGroupFamily` + `Description` For more information about creating a DB parameter group, see [Creating a DB parameter group in Amazon RDS](USER_WorkingWithParamGroups.Creating.md). 1. Modify the parameters in the custom parameter group that you created by using the RDS API [https://docs.amazonaws.cn/AmazonRDS/latest/APIReference/API_ModifyDBParameterGroup.html](https://docs.amazonaws.cn/AmazonRDS/latest/APIReference/API_ModifyDBParameterGroup.html) operation. Include the following required parameters: + `DBParameterGroupName` + `Parameters` For more information about modifying a parameter group, see [Modifying parameters in a DB parameter group in Amazon RDS](USER_WorkingWithParamGroups.Modifying.md). Now you are ready to create a DB instance and attach the custom parameter group to the DB instance. For more information, see [Creating an Amazon RDS DB instance](USER_CreateDBInstance.md) and [Associating a DB parameter group with a DB instance in Amazon RDS](USER_WorkingWithParamGroups.Associating.md). ### Integrating with Amazon License Manager To aid in monitoring RDS for Db2 license usage in the BYOL model, [Amazon License Manager](https://www.amazonaws.cn/license-manager/) integrates with RDS for Db2. License Manager supports tracking of RDS for Db2 engine editions based on virtual CPUs (vCPUs). You can also use License Manager with Amazon Organizations to manage all of your organizational accounts centrally. To track license usage of your RDS for Db2 DB instances, you must create self-managed licenses. You can create self-managed licenses by using the Amazon Web Services Management Console, the Amazon License Manager CLI, and the Amazon License Manager API. Or, you can automate the creation of self-managed licenses with Amazon CloudFormation and Terraform templates. RDS for Db2 resources that match the product information filter are automatically associated with the self-managed license. Discovery of RDS for Db2 DB instances can take up to 24 hours. The following table shows available values for the Engine Edition product information filter for RDS for Db2. | Value | Description | | --- | --- | | `db2-se` | Db2 Standard Edition | | `db2-ae` | Db2 Advanced Edition | **Topics** + [Terminology](#db2-lms-integration-terms) + [Creating a self-managed license in Amazon License Manager](#db2-lms-integration-tracking) + [Automating the creation of self-managed licenses in Amazon License Manager with templates](#db2-lms-integration-templates) + [Settings for creating self-managed licenses](#db2-settings-lms) #### Terminology This page uses the following terminology when discussing the Amazon RDS integration with Amazon License Manager. Self-managed license Self-managed license is a term used in Amazon License Manager. The Amazon RDS console refers to the license as an Amazon License Manager configuration. A self-managed license contains licensing rules based on the terms of your enterprise agreements. The rules that you create determine how Amazon processes commands that consume licenses. While creating a self-managed license, work closely with your organization's compliance team to review your enterprise agreements. For more information, see [Self-managed licenses in License Manager](https://docs.amazonaws.cn/license-manager/latest/userguide/license-configurations.html). #### Creating a self-managed license in Amazon License Manager You can create a self-managed license by using the Amazon Web Services Management Console, the Amazon License Manager CLI, and the Amazon License Manager API. **Note** If you create an RDS for Db2 DB instance by using the Amazon Web Services Management Console, you will create a self-managed license by entering a name for the license. Then Amazon RDS associates the DB instance with this license. (In the Amazon RDS console, this license is referred to as an Amazon License Manager configuration.) If you want to create an RDS for Db2 DB instance by using the Amazon License Manager CLI or Amazon License Manager API, you must first create a self-managed license with the following steps. The same situation applies to restoring an RDS for Db2 DB instance to a point in time or from a snapshot. ##### Console **To create a self-managed license to track the license usage of your RDS for Db2 DB instances** 1. Go to [https://console.amazonaws.cn/license-manager/](https://console.amazonaws.cn/license-manager/). 1. Create a self-managed license. For instructions, see [Create a self-managed license](https://docs.amazonaws.cn/license-manager/latest/userguide/create-license-configuration.html) in the *Amazon License Manager User Guide*. Add a rule for an **RDS Product Information Filter** in the **Product Information** panel. For more information, see [ProductInformation](https://docs.amazonaws.cn/license-manager/latest/APIReference/API_ProductInformation.html) in the *Amazon License Manager API Reference*. ##### Amazon License Manager CLI **Note** This procedure uses an Amazon License Manager CLI command. To create a self-managed license by using the Amazon CLI, run the Amazon License Manager [create-license-configuration](https://docs.amazonaws.cn/cli/latest/reference/license-manager/create-license-configuration.html) command. Use the `--cli-input-json` or `--cli-input-yaml` options to pass the options to the command. For more information, see [Settings for creating self-managed licenses](#db2-settings-lms). The following command creates a self-managed license for Db2 Standard Edition. ``` aws license-manager create-license-configuration --cli-input-json file://rds-db2-se.json ``` The following JSON is the content of the `rds-db2-se.json` file used in the previous command. ``` { "Name": "rds-db2-se", "Description": "RDS Db2 Standard Edition", "LicenseCountingType": "vCPU", "LicenseCountHardLimit": false, "ProductInformationList": [ { "ResourceType": "RDS", "ProductInformationFilterList": [ { "ProductInformationFilterName": "Engine Edition", "ProductInformationFilterValue": ["db2-se"], "ProductInformationFilterComparator": "EQUALS" } ] } ] } ``` For more information about product information, see [Automated discovery of resource inventory](https://docs.amazonaws.cn/license-manager/latest/userguide/automated-discovery.html) in the *Amazon License Manager User Guide*. For more information about the `--cli-input` parameter, see [Generating Amazon CLI skeleton and input parameters from a JSON or YAML input file](https://docs.amazonaws.cn/cli/latest/userguide/cli-usage-skeleton.html) in the *Amazon CLI User Guide*. ##### Amazon License Manager API **Note** This procedure uses an Amazon License Manager API command. To create a self-managed license, use the [https://docs.amazonaws.cn/license-manager/latest/APIReference/API_CreateLicenseConfiguration.html](https://docs.amazonaws.cn/license-manager/latest/APIReference/API_CreateLicenseConfiguration.html) Amazon License Manager API operation with the following required parameters: + `Name` + `LicenseCountingType` + `ProductInformationList` + `ResourceType` + `ProductInformationFilterList` + `ProductInformationFilterName` + `ProductInformationFilterValue` + `ProductInformationFilterComparator` For more information about the parameters, see [Settings for creating self-managed licenses](#db2-settings-lms). #### Automating the creation of self-managed licenses in Amazon License Manager with templates You can automate the creation of self-managed licenses by using Amazon CloudFormation and Terraform templates. The following example Amazon CloudFormation template creates self-managed licenses for Db2 Standard Edition on RDS for Db2. For a template for Db2 Advanced Edition, update the values for `Name`, `Description`, and `ProductInformationFilter`. ``` AWSTemplateFormatVersion: "2010-09-09" Description: CloudFormation template to create a License Configuration for Db2 Standard Edition on RDS for Db2. Resources: Db2LicenseConfiguration: Type: "AWS::LicenseManager::LicenseConfiguration" Properties: Name: "rds-db2-se" Description: "Db2 Standard Edition on RDS for Db2" LicenseCountingType: "vCPU" LicenseCountHardLimit: false ProductInformationList: - ResourceType: "RDS" ProductInformationFilterList: - ProductInformationFilterName: "Engine Edition" ProductInformationFilterValue: - "db2-se" ProductInformationFilterComparator: "EQUALS" ``` For more information about using Amazon CloudFormation with Amazon RDS, see [Creating Amazon RDS resources with Amazon CloudFormation](creating-resources-with-cloudformation.md). The following example Terraform template creates self-managed licenses for Db2 Standard Edition on RDS for Db2. Replace {{us-east-1}} with your Amazon Web Services Region. For a template for Db2 Advanced Edition, update the values for `name`, `description`, and `product_information_filter`. ``` provider "aws" { region = "{{us-east-1}}" } resource "aws_licensemanager_license_configuration" "rds_db2_license_config" { name = "rds-db2-se" description = "Db2 Standard Edition on RDS for Db2 license_counting_type = "vCPU" license_count_hard_limit = false product_information_list { resource_type = "RDS" product_information_filter { name = "Engine Edition" comparator = "EQUALS" value = ["db2-se"] } } } ``` For more information about using Terraform and Amazon RDS, see [Using Terraform as an IaC tool for the Amazon Web Services Cloud](https://docs.amazonaws.cn/prescriptive-guidance/latest/choose-iac-tool/terraform.html) and [Best practices for using the Terraform Amazon Provider](https://docs.amazonaws.cn/prescriptive-guidance/latest/terraform-aws-provider-best-practices/introduction.html) in * Amazon Prescriptive Guidance*. #### Settings for creating self-managed licenses In the following table, you can find details about the settings for creating self-managed licenses by using the Amazon License Manager CLI, the Amazon License Manager API, an Amazon CloudFormation template, and a Terraform template. The parameter name in the following table appears in the format of the name used in the Amazon License Manager API and the Amazon CloudFormation template. | Parameter name | Data type | Required | Description | | --- | --- | --- | --- | | Name | string | Yes | The name of the license configuration. | | Description | string | No | The description of the license configuration. | | LicenseCountingType | string | Yes | The dimension used to track the license inventory. Valid value: `vCPU`. | | LicenseCountHardLimit | boolean | No | Indicates whether hard or soft license enforcement is used. Exceeding a hard limit blocks the launch of new instances. | | ProductInformationList | array of objects | Yes | A list of product information for a license configuration. | | ResourceType | string | Yes | The resource type. Valid value: `RDS`. | | ProductInformationFilterList | array of objects | Yes | A list of product information filters for a license configuration. | | ProductInformationFilterName | string | Yes | The name of the type of filter being declared. Valid value: `Engine Edition`. | | ProductInformationFilterValue | array of strings | Yes | The value to filter on. You must only specify one value. Valid values: `db2-se` or `db2-ae`. | | ProductInformationFilterComparator | string | Yes | The logical operator for ProductInformationFilterName. Valid value: EQUALS. | ## Db2 license through Amazon Web Services Marketplace In the Db2 license through Amazon Web Services Marketplace model, you pay an hourly rate to subscribe to Db2 licenses. This model helps you get started quickly with RDS for Db2 without needing to purchase licenses. To use Db2 license through Amazon Web Services Marketplace, you need an active Amazon Web Services Marketplace subscription for the particular IBM Db2 edition that you want to use. If you don't already have one, [subscribe to Amazon Web Services Marketplace](#db2-marketplace-subscribing-registering) for that IBM Db2 edition. Amazon RDS supports Db2 license through Amazon Web Services Marketplace for IBM Db2 Standard Edition and IBM Db2 Advanced Edition. **Topics** + [Terminology](#db2-marketplace-terminology) + [Payments and billing](#db2-marketplace-billing) + [Subscribing to Db2 Marketplace listings and registering with IBM](#db2-marketplace-subscribing-registering) + [Obtaining a private offer](#db2-marketplace-private-offer) ### Terminology This page uses the following terminology when discussing the Amazon RDS integration with Amazon Web Services Marketplace. SaaS subscription In Amazon Web Services Marketplace, software-as-a-service (SaaS) products such as the pay-as-you-go license model adopt a usage-based subscription model. IBM, the software seller for Db2, tracks your usage and you pay only for what you use. Public offer Public offers allow you to purchase Amazon Web Services Marketplace products directly from the Amazon Web Services Management Console. Private offer Private offers are a purchasing program that allow sellers and buyers to negotiate custom prices and end user licensing agreement (EULA) terms for purchases in Amazon Web Services Marketplace. Db2 Marketplace fees Fees charged for the Db2 software license usage by IBM. These service fees are metered through Amazon Web Services Marketplace and appear on your Amazon bill under the Amazon Web Services Marketplace section. Amazon RDS fees Fees that Amazon charges for the RDS for Db2 services, which excludes licenses when using Amazon Web Services Marketplace for Db2 licenses. Fees are metered through the Amazon RDS service being used and appear on your Amazon bill. ### Payments and billing RDS for Db2 integrates with Amazon Web Services Marketplace to offer hourly, pay-as-you-go licenses for Db2. The Db2 Marketplace fees cover the license costs of the Db2 software, and the Amazon RDS fees cover the costs of your RDS for Db2 DB instance usage. For information about pricing, see [Amazon RDS for Db2 pricing](https://www.amazonaws.cn/rds/db2/pricing/). To stop these fees, you must delete any RDS for Db2 DB instances. In addition, you can remove your subscriptions to Amazon Web Services Marketplace for Db2 licenses. If you remove your subscriptions without deleting your DB instances, Amazon RDS will continue to bill you for the use of the DB instances. For more information, see [Deleting a DB instance](USER_DeleteInstance.md). You can view bills and manage payments for your RDS for Db2 DB instances that use Db2 license through Amazon Web Services Marketplace in the [Amazon Billing console](https://console.aws.amazon.com/billing). Your bills includes two charges: one for your usage of Db2 license through Amazon Web Services Marketplace and one for your usage of Amazon RDS. For more information about billing, see [Viewing your bill](https://docs.amazonaws.cn/awsaccountbilling/latest/aboutv2/getting-viewing-bill.html) in the *Amazon Billing and Cost Management User Guide*. ### Subscribing to Db2 Marketplace listings and registering with IBM To use Db2 license through Amazon Web Services Marketplace, you must use the Amazon Web Services Management Console to complete the following two tasks. You can't complete these tasks through the Amazon CLI or the RDS API. **Note** If you want to create your DB instances by using the Amazon CLI or the RDS API, you must complete these two tasks first. **Topics** + [Task 1: Subscribe to Db2 in Amazon Web Services Marketplace](#db2-marketplace-subscribing) + [Task 2: Register your subscription with IBM](#db2-marketplace-registering) #### Task 1: Subscribe to Db2 in Amazon Web Services Marketplace To use Db2 license with Amazon Web Services Marketplace, you need to have an active Amazon Web Services Marketplace subscription for Db2. Because subscriptions are associated with a specific IBM Db2 edition, you need to subscribe to Db2 in Amazon Web Services Marketplace for each edition of Db2 that you want to use: [IBM Db2 Advanced Edition](https://www.amazonaws.cn/marketplace/pp/prodview-w6m4yctzzy5fk), [IBM Db2 Standard Edition](https://www.amazonaws.cn/marketplace/pp/prodview-gbsgwalbkphv6). For information about Amazon Web Services Marketplace subscriptions, see [Saas usage-based subscriptions](https://docs.amazonaws.cn/marketplace/latest/buyerguide/buyer-saas-products.html#saas-pricing-models) in the *Amazon Web Services Marketplace Buyer Guide*. We recommend that you subscribe to Db2 in Amazon Web Services Marketplace *before* you start to [create a DB instance](USER_CreateDBInstance.md). #### Task 2: Register your subscription with IBM After you subscribe to Db2 in Amazon Web Services Marketplace, complete the registration of your IBM order from the Amazon Web Services Marketplace page for the type of Db2 subscription that you chose. On the Amazon Web Services Marketplace page, choose **View purchase options**, and then choose **Set up your account**. You can register either with your existing IBM account or by creating a free IBM account. ### Obtaining a private offer You can request an Amazon Web Services Marketplace private offer for Db2 from IBM. For more information, see [Private offers](https://docs.amazonaws.cn/marketplace/latest/buyerguide/buyer-private-offers.html) in the *Amazon Web Services Marketplace Buyer Guide*. **Note** If you are an Amazon Organizations user and received a private offer that was issued to your payer and member accounts, follow the procedure below to subscribe to Db2 directly on each account in your organization. **To obtain a Db2 private offer** 1. After a private offer has been issued, sign in to the Amazon Web Services Marketplace Console. 1. Open the email with a Db2 private offer link. 1. Follow the link to directly access the private offer. **Note** Following this link before logging in to the correct account will result in a **Page note found** (404) error. 1. Review the terms and conditions. 1. Choose **Accept terms**. **Note** If an Amazon Web Services Marketplace private offer is not accepted, the Db2 service fees from Amazon Web Services Marketplace will continue to be billed at the public hourly rate. 1. To verify the offer details, select **Show details** in the product listing. After you've completed the procedure, you can create your DB instance by following the steps in [Creating an Amazon RDS DB instance](USER_CreateDBInstance.md). In the Amazon Web Services Management Console, under **License**, make sure that you choose **Through Amazon Web Services Marketplace**. ## Switching between Db2 licenses You can switch between Db2 licenses in RDS for Db2. For example, you can start with bring your own license (BYOL), and then switch to Db2 license through Amazon Web Services Marketplace. **Important** If you want to switch to Db2 license through Amazon Web Services Marketplace, make sure that you have an active Amazon Web Services Marketplace subscription for the IBM Db2 edition that you want to use. If you don't, first [subscribe to Db2 in Amazon Web Services Marketplace](#db2-marketplace-subscribing-registering) for that Db2 edition, and then complete the restore procedure. ### Console **To switch between Db2 licenses** 1. Sign in to the Amazon Web Services Management Console and open the Amazon RDS console at [https://console.amazonaws.cn/rds/](https://console.amazonaws.cn/rds/). 1. In the navigation pane, choose **Automated backups**. The automated backups are displayed on the **Current Region** tab. 1. Choose the DB instance that you want to restore. 1. For **Actions**, choose **Restore to point in time**. The **Restore to point in time** window appears. 1. Choose **Latest restorable time** to restore to the latest possible time, or choose **Custom** to choose a time. If you chose **Custom**, enter the date and time you want to restore the instance to. **Note** Times are shown in your local time zone, which is indicated by an offset from Coordinated Universal Time (UTC). For example, UTC-5 is Eastern Standard Time/Central Daylight Time. 1. For **DB engine**, choose the Db2 license you want to use. 1. For **DB instance identifier**, enter the name of the target restored DB instance. The name must be unique. 1. Choose other options as needed, such as DB instance class, storage, and whether you want to use storage autoscaling. For information about each setting, see [Settings for DB instances](USER_CreateDBInstance.Settings.md). 1. Choose **Restore to point in time**. For more information, see [Restoring a DB instance to a specified time for Amazon RDS](USER_PIT.md). ### Amazon CLI To switch between Db2 licenses, run the [restore-db-instance-to-point-in-time](https://docs.amazonaws.cn/cli/latest/reference/rds/restore-db-instance-to-point-in-time.html) command. The following example restores the latest point-in-time version, sets the DB engine to IBM Db2 Advanced Edition, and sets the license model to Db2 license through Amazon Web Services Marketplace. You can specify other settings. For information about each setting, see [Settings for DB instances](USER_CreateDBInstance.Settings.md). **Example** For Linux, macOS, or Unix: ``` 1. aws rds restore-db-instance-to-point-in-time \ 2. --source-db-instance-identifier {{my_source_db_instance}} \ 3. --target-db-instance-identifier {{my_target_db_instance}} \ 4. --use-latest-restorable-time \ 5. --engine {{db2-ae}} \ 6. --license-model {{marketplace-license}} ``` For Windows: ``` 1. aws rds restore-db-instance-to-point-in-time ^ 2. --source-db-instance-identifier {{my_source_db_instance}} ^ 3. --target-db-instance-identifier {{my_target_db_instance}} ^ 4. --use-latest-restorable-time ^ 5. --engine {{db2-ae}} ^ 6. --license-model {{marketplace-license}} ``` For more information, see [Restoring a DB instance to a specified time for Amazon RDS](USER_PIT.md). ### RDS API To switch between Db2 licenses, call the Amazon RDS API [https://docs.amazonaws.cn/AmazonRDS/latest/APIReference/API_RestoreDBInstanceToPointInTime.html](https://docs.amazonaws.cn/AmazonRDS/latest/APIReference/API_RestoreDBInstanceToPointInTime.html) operation with the following parameters: + `SourceDBInstanceIdentifier` + `TargetDBInstanceIdentifier` + `RestoreTime` + `Engine` + `LicenseModel` For more information, see [Restoring a DB instance to a specified time for Amazon RDS](USER_PIT.md).
