This document describes operations on the instance list and management pages in the TencentDB for MySQL Console.

Instance List Page

You can log in to the TencentDB for MySQL Console and enter the instance list page to view instance information and manage your instances.

Feature	Description
Configuration adjustment	In the instance list, you can adjust the configuration (i.e., scaling) of your database instance. Both instance upgrade and downgrade are supported. For more information, please see Adjusting Database Instance Specification.
Rollback	In the instance list, select the instance to be rolled back and select More > Rollback to roll it back to a specified time point based on cold backup and binlog. For more information, please see Data Rollback.
Restart	In the instance list, select an instance and click Restart to restart it. You can also select multiple instances for batch restart. During the restart, the instance will be inaccessible, and existing connections to it will be closed. Please be prepared for the restart to avoid business interruption. During the restart, if the number of business writes is high and there are too many dirty pages, the restart will fail. In this case, the instance will go back to the state before the restart and become accessible. Please restart instances during off-peak hours to ensure the restart success rate and reduce the impact on your business.
