Restart an instance
Restarting a PolarDB-X instance closes all active connections and briefly interrupts service while the database engine process restarts. Use this operation when the instance has exceeded its maximum number of connections or is experiencing performance issues.
Restart an instance
Restarting an instance disconnects all applications from the database. Schedule the restart during low-traffic periods and make sure your application can handle reconnection.

On the Instances page, click the PolarDB-X 2.0 tab.
Find the target instance and click its ID.
On the Basic information page, click Restart Instance in the upper-right corner.
In the message that appears, click OK.
