Configuring the Maintenance Window

During a maintenance window, Huawei Cloud O&M personnel perform maintenance operations on the instance. To prevent service interruptions, set the maintenance window to off-peak hours.

The default maintenance window is 02:00–06:00 but you can change it if needed.

Precautions

Before maintenance is performed, DDS will send SMS and email notifications to the contact person you specified in the HUAWEI CLOUD account.
During the maintenance window, the DB instance will be intermittently disconnected for once or twice. Ensure that your applications support automatic reconnection.
Changing the maintenance window does not affect the execution of tasks that have been scheduled.

Click in the upper left corner and select a region and a project.
Click in the upper left corner of the page and choose Databases > Document Database Service.
