# GET /#Action=ResetDBParameterGroup

`GET /#Action=ResetDBParameterGroup`

Modifies the parameters of a DB parameter group to the engine/system default value. To reset specific parameters, provide a list of the following: <code>ParameterName</code> and <code>ApplyMethod</code>. To reset the entire DB parameter group, specify the <code>DBParameterGroup</code> name and <code>ResetAllParameters</code> parameters. When resetting the entire group, dynamic parameters are updated immediately and static parameters are set to <code>pending-reboot</code> to take effect on the next DB instance restart or <code>RebootDBInstance</code> request.
