Content Lookup in configuration Manager

Whether it is Software distribution , Software updates deployment or application deployment in 2012 the Majority of the issues comes is w.r.t to the clients not getting the Contents.

This Blogs is on how we can check and find out the reason why the client is not able to get the contents.

Whenever Client needs a content it will ask its local management point for the content and management point check against the site database and return back the list of distribution point which is used by the client.

Boundaries \ Boundary group are a important part while content lookup are made. The boundaries and boundary group can be used to limit the DP which can server a client for content lookup.
 
This link talks about the DP selection logic and generic flow http://technet.microsoft.com/en-us/library/bb932150.aspx
 
If you are looking at a top level flow this is what happens
 
The content access service component (CAS) of Ccmexec service will Request for Content . The content transfer Manager (CTM)will create  a CTM job and the location services will send the content request to MP and receive the reply from MP and the same is used by CAS which in turn starts the Data transfer job to download the content.
That said easy let us look in to more depth Flow
 
Software distribution ( Legacy Package )
 
The reference package in this case is P010000F
 
When the execmgr is trigged for a particular advertisement the request will be given to CAS. Log snippet will be as follows in the client
 
Execmgr.log

One the request reaches the Management point , the MP_location Manager component will query the DB and get the reply according to the request. You can clearly see the request and the reply once you enable verbose logging on the MP.
 
MP_Location.log
 
 MP LM: Message Body : <ContentLocationRequest SchemaVersion="1.00" ExcludeFileList=""><Package ID="P010000F" Version="1"/><AssignedSite SiteCode="P01"/><ClientLocationInfo LocationType="SMSPackage" DistributeOnDemand="0" UseAzure="0" AllowWUMU="0" UseProtected="1" AllowCaching="0" BranchDPFlags="0" UseInternetDP="0" AllowHTTP="1" AllowSMB="1" AllowMulticast="1"><ADSite Name="Default-First-Site-Name"/><Forest Name="msdindia.com"/><Domain Name="msdindia.com"/><IPAddresses><IPAddress SubnetAddress="192.168.1.0" Address="192.168.1.54"/></IPAddresses></ClientLocationInfo></ContentLocationRequest>

The details supplied on the request becomes the parameter for the SP. The SP which will be run and the parameter is shown below.
 

exec MP_GetContentDPInfoUnprotected N'P010000F',N'1',N'P01',N'SMSPackage',N'0',N'msdindia.com',N'msdindia.com',N'<ClientLocationInfo LocationType="SMSPackage" DistributeOnDemand="0"

Now at the client side you can see the reply in location services.log. The CTM will then hand over this information to CAS and you can see the list of DP in CAS which has the content. The list is purely dependent on the request which you had made and it is the policy on the client which will help in frame the request.

Once the list is made the CTM will create a DTS job and the DTS will download the content to the cache which will be informed to the execmgr.

Application deployment

The flow is the same the only difference would in the request

So only the MP_location.log will have the difference

MP_location.log

Package ID is easy to spot for the Content ID for a application you can get it from console.

 

 

Software Update Deployment

 In case of software deployment also it is the content ID. But the content ID is not as open as a application or package. For normal updates it will be the unique ID for the bundled ones we can find like this.

Click on the picture if you would like to see the picture clear. Here we have a update which is bundle Update :Security Update for Windows 7 for x64-based Systems (KB2532531) MS11-053(6e03d226-b005-4be7-8254-7c1760886bfd)

 

The request , reply in mp_location would look like this

Here updatehanlder will request CAS
