Deploying ColdFusion with LCDS Express in a multiple CPU machine

For those who might considering using LCDS with ColdFusion you should be aware of LCDS license restrictions for the Express version of the product.

License: With respect to each unique application created by Licensee, Adobe grants Licensee a license to install and use such unique application and the Adobe LiveCycle Data Services Express Software as Production Software on a Per-CPU basis; provided that Licensee shall not: (a) install, use or access such unique application and/or the Adobe LiveCycle Data Services Express Software on more than one CPU, (b) cluster any CPUs, and/or (c) use load balancing.

So basically, your LCDS server cannot use more than 1 physical CPU (multi cores are allowed).

A way of limiting your server to communicate to a single CPU is to implement CPU affinity which will bind a process to a specific amount of available CPUs.

It seems that Unix has a pbind command which allows you to achieve this. For windows, I found FireDaemon which allows us to install new services with a lot of options, one being the possibility to start a service and bind it to a specific CPU. So in a dual quad-core CPU server, you could bind your LCDS server service to 4 cores without breaking the license.

If using ColdFusion with the integrated LCDS server, it will require that the ColdFusion server must also be limited to a single CPU (multi-cores allowed).

If you don't want to limit your ColdFusion server instance, you can always deploy LCDS in a different server instance and have them talk through RMI.
