# RDS Database Stack \$1 Update Maintenance Window (Managed Automation)


Update an existing RDS maintenance window, which is a weekly time range (in UTC) during which system maintenance can occur. Changing an RDS maintenance window doesn't result in an outage. If moving this window to the current time, there must be at least 30 minutes between the current time and the end of the current window to ensure pending changes are applied.

How it works:

1. Navigate to the **Create RFC** page: In the left navigation pane of the AMS console click **RFCs** to open the RFCs list page, and then click **Create RFC**.

1. Choose a popular change type (CT) in the default **Browse change types** view, or select a CT in the **Choose by category** view.
   + **Browse by change type**: You can click on a popular CT in the **Quick create** area to immediately open the **Run RFC** page. Note that you cannot choose an older CT version with quick create.

     To sort CTs, use the **All change types** area in either the **Card** or **Table** view. In either view, select a CT and then click **Create RFC** to open the **Run RFC** page. If applicable, a **Create with older version** option appears next to the **Create RFC** button.
   + **Choose by category**: Select a category, subcategory, item, and operation and the CT details box opens with an option to **Create with older version** if applicable. Click **Create RFC** to open the **Run RFC** page.

1. On the **Run RFC** page, open the CT name area to see the CT details box. A **Subject** is required (this is filled in for you if you choose your CT in the **Browse change types** view). Open the **Additional configuration** area to add information about the RFC.

   In the **Execution configuration** area, use available drop-down lists or enter values for the required parameters. To configure optional execution parameters, open the **Additional configuration** area.

1. When finished, click **Run**. If there are no errors, the **RFC successfully created** page displays with the submitted RFC details, and the initial **Run output**. 

1. Open the **Run parameters** area to see the configurations you submitted. Refresh the page to update the RFC execution status. Optionally, cancel the RFC or create a copy of it with the options at the top of the page.

#### Updating an RDS maintainance window with the CLI


How it works:

1. Use either the Inline Create (you issue a `create-rfc` command with all RFC and execution parameters included), or Template Create (you create two JSON files, one for the RFC parameters and one for the execution parameters) and issue the `create-rfc` command with the two files as input. Both methods are described here.

1. Submit the RFC: `aws amscm submit-rfc --rfc-id ID` command with the returned RFC ID.

   Monitor the RFC: `aws amscm get-rfc --rfc-id ID` command.

To check the change type version, use this command:

```
aws amscm list-change-type-version-summaries --filter Attribute=ChangeTypeId,Value=CT_ID
```
**Note**  
You can use any `CreateRfc` parameters with any RFC whether or not they are part of the schema for the change type. For example, to get notifications when the RFC status changes, add this line, `--notification "{\"Email\": {\"EmailRecipients\" : [\"email@example.com\"]}}"` to the RFC parameters part of the request (not the execution parameters). For a list of all CreateRfc parameters, see the [AMS Change Management API Reference](https://docs.aws.amazon.com/managedservices/latest/ApiReference-cm/API_CreateRfc.html).

*INLINE CREATE*:

Issue the create RFC command with execution parameters provided inline (escape quotation marks when providing execution parameters inline), and then submit the returned RFC ID. For example, you can replace the contents with something like this:

```
aws amscm create-rfc --change-type-id "ct-27jjy5wnrfef2" --change-type-version "1.0" --title "Update RDS Maintenance Window" --execution-parameters "{\"DBIdentifierArn\": \"arn:aws:rds:us-east-1:123456789101:db:database-1\", \"PreferredMaintenanceWindow\": \"Sun:04:00-Sun:04:30\"}"
```

*TEMPLATE CREATE*:

1. Output the execution parameters for this change type to a JSON file named UpdateRDSMaintenanceWindowParams.json.

   ```
   aws amscm get-change-type-version --change-type-id "ct-27jjy5wnrfef2" --query "ChangeTypeVersion.ExecutionInputSchema" --output text > UpdateRDSMaintenanceWindowParams.json
   ```

1. Modify and save the execution parameters JSON file. For example, you can replace the contents with something like this:

   ```
   {
     "DBIdentifierArn": "arn:aws:rds:us-east-1:123456789101:db:database-1",
     "PreferredMaintenanceWindow": "Sun:04:00-Sun:04:30"
   }
   ```

1. Output the JSON template to a file in your current folder; this example names it UpdateRDSMaintenanceWindowRfc.json:

   ```
   aws amscm create-rfc --generate-cli-skeleton > UpdateRDSMaintenanceWindowRfc.json
   ```

1. Modify and save the UpdateRDSMaintenanceWindowRfc.json file. For example, you can replace the contents with something like this:

   ```
   {
     "ChangeTypeVersion": "1.0",
     "ChangeTypeId": "ct-27jjy5wnrfef2",
     "Title": "Update RDS Maintenance Window"
   }
   ```

1. Create the RFC, specifying the execution parameters file and the UpdateRDSMaintenanceWindowRfc.json file:

   ```
   aws amscm create-rfc --cli-input-json file://UpdateRDSMaintenanceWindowRfc.json --execution-parameters file://UpdateRDSMaintenanceWindowParams.json
   ```

   You receive the ID of the new RFC in the response and can use it to submit and monitor the RFC. Until you submit it, the RFC remains in the editing state and does not start.

#### Tips


**Note**  
AMS employs drift detection on certain stacks, including RDS stacks, to determine if configuration changes. The AMS disallows updates to an RDS stack that has been determined to have configuration drift. The RFC will fail with the following error message: "Update cannot be performed on this stack, please contact AMS for further assistance."
