# RebootDBInstance
<a name="API_RebootDBInstance"></a>

You might need to reboot your instance, usually for maintenance reasons. For example, if you make certain changes, or if you change the cluster parameter group that is associated with the instance, you must reboot the instance for the changes to take effect. 

Rebooting an instance restarts the database engine service. Rebooting an instance results in a momentary outage, during which the instance status is set to *rebooting*.
