Topics:

• Policy Processing Engine

• Profile update tool

Policy Processing Engine

Policy Processing Engine or PPE is implemented as a Windows Service which starts execution as soon as the machine boots up regardless

of whether the user is logged in or not.

This module provides an interface which can be used to perform the following tasks:

• Activate or deactivate profiles

• Enumerate input and output parameters to allow new policies to be created

• Save and retrieve profiles and policies for machines, users or third-party Dell Precision Optimizer applications.

Profile update tool

This command line tool (profUpd.exe) is used by Dell Precision Optimizer UI to check and update the profiles from the Dell server. A local

configuration file must be used to inform Dell Precision Optimizer the Dell server address and which protocol to use such as HTTP,

HTTPS, or FTP.

NOTE: All profiles and policies on the server are digitally signed and stored encrypted using AES-256 algorithm.
