This topic describes how to use the console or API to view and reconfigure some parameters for an RDS for PPAS instance. You can also use the console to query the parameter reconfiguration history.

Precautions

  • When you reconfigure parameters on the Parameters page, see the Value Range column corresponding to each parameter.
  • After you reconfigure certain parameters, you must restart the RDS instance for the changes to take effect. For more information, see the Restart column on the Parameters page. A restart disconnects the RDS instance. We recommend that you make appropriate service arrangements before you restart an RDS instance. Proceed with caution.
