ApsaraDB RDS:Configure a maintenance window

For more information about how to configure the maintenance window of an RDS instance that runs another database engine, see the following topics:

• Set the maintenance window of an ApsaraDB RDS for SQL Server instance

• Set the maintenance window of an ApsaraDB RDS for PostgreSQL instance

• Set the maintenance window of an ApsaraDB RDS for MariaDB instance

Usage notes

• Before the maintenance starts, the system sends emails to the contacts that are associated with your Alibaba Cloud account. We recommend that you check your email box on a regular basis to obtain up-to-date information.

• When the maintenance window arrives, your RDS instance enters the Maintaining Instance state. This ensures a smooth maintenance process. When the RDS instance is in this state, database access and query operations such as performance monitoring are not affected. However, except for account management, database management, and IP address whitelist configuration, modification operations such as upgrade, downgrade, and restart are temporarily unavailable.

• During the maintenance window, one or two instance switchovers occur. Make sure that your application is configured to automatically reconnect to your RDS instance. For more information about the impacts of an instance switchover, see Impacts of an instance switchover.

Modify the maintenance window of a single RDS instance

1. Go to the Instances page. In the top navigation bar, select the region in which the RDS instance resides. Then, find the RDS instance and click the ID of the instance.

2. In the Configuration Information section, click Settings to the right of Maintenance Window.

3. Configure the Start Time and End Time parameters and save the settings.

   Note

   The time zone of the displayed maintenance window is the same as the time zone of the computer used to log on to the ApsaraDB RDS console.

Modify the maintenance window of multiple RDS instances at a time

1. Log on to the ApsaraDB RDS console. In the left-side navigation pane, click Instances. In the top navigation bar, select the region in which your RDS instance resides.

2. Select the RDS instances whose maintenance window you want to modify and click Modify Maintenance Window below the instance list.

3. In the Modify Maintenance Window dialog box, select an appropriate maintenance window and click OK.

   Note

   The time zone of the maintenance window is the same as that of the computer that you use to log on to the ApsaraDB RDS console.
