This topic describes how to disable the database proxy mode for an RDS for PPAS instance. Disabling the database proxy mode means switching to the standard mode, which helps improve the performance of the RDS instance.

Notice If network links are not upgraded in a timely manner, some unintended service disruptions may occur in the database proxy mode. For example, network jitter may occur when you attempt to access resources. You must upgrade your RDS network link in time to ensure that your service is running smoothly. For more information, see Upgrade the RDS network link.
