      Log in to the TencentDB for SQL Server console, and enter the instance list page to view the instance information and manage your instances.
      
      Feature
      Description
      Restart
      In the instance list, select an instance and click Restart at the top to restart it. You can also select multiple instances for batch restart.
      The instance will be inaccessible during the restart, and existing connections to it will be closed.
      If the number of business writes is high during the restart, the restart will fail. In this case, the instance will go back to the state before the restart and become accessible.
      Restart the instance during off-peak hours to ensure success and minimize the impact on your business.
      Renew
      In the instance list, select one or more target instances, click Renew to renew them by month or year.
      Set Auto-Renewal
      In the instance list, select one or more target instances, and click More > Set Auto-Renewal to set monthly auto-renewal for them. After you click OK, the instances will be automatically renewed monthly upon expiration if your Tencent Cloud account balance is sufficient.
