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 intermittently disconnected for one or two times. Ensure that your applications support automatic reconnection.

Procedure

  1. Log in to the management console.
  2. Click in the upper left corner of the page and choose Databases > Relational Database Service.
  3. On the Instances page, click the target DB instance. In the DB Information area on the Basic Information page, click Change next to the Maintenance Window field.

  4. In the displayed dialog box, click Yes.

    Changing the maintenance window does not affect the execution time of the scheduled tasks in the original maintenance period.
