Set parameters

Last Updated: May 03, 2017

RDS allows you to define some instance parameters. For details about the parameters that can be configured, see Parameter Settings on the RDS Console .


  • Configure parameters only within the permissible value ranges shown on the parameter settings page.

  • The instance must be restarted after modifying certain parameters. Refer to the parameter settings page to confirm if a restart is required. Before restarting, to avoid any interruption of production, ensure the appropriate business arrangements.
