Lately I have been getting right into Powershell scripting
and I have been trying to build an auditing utility which HMC 4.5 Cross Data
Store (CrossDS) was supposed to provide.
In building this auditing tool, I have built some basic Powershell
scripts on the way that may help others understand how to develop for MPS.
A basic script I have uploaded is called
GetUserPlan.ps1. Note : I have renamed it to .txt extension just in case your proxy server filters .ps1 extensions.
This script should give you an idea on how to make MPS calls from within Powershell.
