Set maintenance window

Last Updated: May 31, 2020


To guarantee the stability of ApsaraDB for Memcache instances, the backend system irregularly maintains instances and machines on the Alibaba Cloud platform.

Before official maintenance, ApsaraDB for Memcache sends SMS messages and emails to contacts configured on your Alibaba Cloud account.

To guarantee stability during the maintenance process, instances enter the Being Maintained state before the preset O&M time on the day of maintenance. When an instance is in this state, normal access to data in the database is not affected. However, change-related functions (for example, configuration changes) are temporarily unavailable for this instance on the console, whereas query functions such as performance monitoring are still available.

Note: After the preset O&M time is reached, instances may experience intermittent interruption during maintenance, so we recommend that instances be maintained during off-peak hours if possible.


  1. Log on to the Memcache console and locate the target instance.

  2. Click Instance ID or Manage to go to the Instance Information page.

  3. Click Set next to O&M Time in Basic Information.

    The default O&M time for ApsaraDB for Memcache is from 02:00 to 06:00.

  1. Select an O&M time and click Save.

    Note: The O&M time is in Beijing time.
