The Unique Application ID

If you ask me the biggest change in SCCM 2012 is the backend. The DP and MP can be combined and it will use SQL replication (execpt for content). Another interresting change is the use of application. It’s an evolution of SCCM 2007 packages (still supporting in 2012).

First thing you have to take in mind is that application installation will run in 64-bit mode. Although you can also force to use 32-bit. the current packages still run in 32-bit mode and cannot run in 64-bit. So you can say that packages are obsolete.

If you look at the backend a package difference a lot from a package. Especially the unique id. Where you have a package id in package a applications has multiple unique keys.

  • First you have the CI_ID which is just a number. My guess is that this is site specific.
  • ┬áThe second key is what looks like a packageid. This key will be used for the content.
  • ┬áThe Third key is long descriptor that starts with scope_[guid]\application_[guid].
    First part is the unique identification of the site server and the second part is the unique id for the application. This key I guess will be used at the entire environment. But that has to be checked when RTM arrived.
$identificationClass = [WMICLASS]"\\$($SccmServer.Machine)\$($SccmServer.Namespace):SMS_Identification"
$cls = Get-WmiObject SMS_Identification -namespace $SccmServer.Namespace -ComputerName $SccmServer.Machine -list
$tmp = $identificationClass.GetSiteID().SiteID
return "ScopeId_$($tmp.Substring(1,$tmp.Length -2))"

I will update this post when more information and documentation is availble
