R. Installation – DMG

R.1 What are the different architectural possibilities about the DMG

components installation?

The DMG components are independent and may be installed on separate machines. They are splitted

over three installation packages.

- The DMG Anchor containing the callback libraries and the request processor

- The DMG Relay containing the callback collector and the request distributor

- The DMG Server containing Apache, PHP5 and the DMG Interface

- The DMG Anchor package must be installed on a machine where Xprint is running

- The callback collector and the request distributor can be installed on a separate machine despites of

the fact that they belong to the same package (DMG Relay). They can be installed on a machine not

running an Xprint system. There is however an exception regarding windows because on windows

both the callback collector and the request distributor must be installed on a system where Xprint is

running.

- The DMG Server can be installed on any machine that is network reachable.

According to the customer needs and to the above explanation, you could for instance follow these

isntallation scenarios:

- One machine to install all the packages

Xprint core + DMG Anchor + DMG Relay + DMG Server on the same machine. This installation

scenario is only applicable to configurations that do not need much resource.

This scenario is the easiest one to configure but the less interesting in terms of performance.

- An Xprint domain and a dedicated machine for all the DMG components

DMG Relay + DMG Server on a dedicated machine. This machine has to be network reachable.

This scenario is more efficient than the previous one because the work load is spread over several

machines.

- An Xprint domain and two dedicated machines

If the DMG has to be used over the internet, the DMG server has to be installed in a DMZ. In this case,

installing the DMG Relay on a machine located in the intranet will greatly ease the Firewall

configuration. Note that in this case the DMG Relay package can also be installed on one machine of the

Xprint domain
