Changing the Maintenance Window

Scenarios

The maintenance window is 02:00–06:00 by default and you can change it as required. To prevent service interruptions, you are advised to set the maintenance window to off-peak hours.

Precautions

• During the maintenance window, the DB instance will be briefly disconnected once or twice. Ensure that your applications support automatic reconnection.
• Changing the maintenance window does not affect the execution time of the scheduled tasks in the original maintenance period.
