Service Manager 2012 R2 Looking for the SDK method for Select All management packs OMCI Connector

Question

Hi all,
I'm working through a script that updates the OpsMgr CI connector's MP sync list after a MP import. What I want to do is a Select All to sync the OpsMgr MP's I just imported into Service Manager. Just like checking the Select All
box after refreshing the connector in the GUI.
I have been through the cmdlets and looked at the assemblies in VS. I can't find the method that does this.
I found IsNullPropertySkipped under
Microsoft.EnterpriseManagement.ServiceManager.Connectors.OpsMgr but that's it
And nothing in here
Microsoft.EnterpriseManagement.ServiceManager.Sdk.Connectors.Connector
Must be missing it, and am not having much luck with TechNet.
Thanks much–Drew

I'm afraid you won't find a quick'n'easy solution for this. I'll start out by saying I don't know if Powershell has any cmdlets for this..but I know you can use the .NET SDK via powershell to do whatever you need to do. So my post focuses on the SDK/C#. You
should be able to adapt it in Powershell.
The function you want to replicate (check-all) is unique to the Operations Manager CI connector implementation and, as such, my post below may sound a bit overwhelming.
Let me start by describing where an OM CI connector's selected management packs are stored. They're stored in the connector's workflow rule (specifically, in its WriteAction module).  Take a look at the ServiceManager.LinkingFramework.Configuration
management pack where all OM CI connector rules are stored. Look for a rule that starts with "OMConnector." (the dot will be followed by some random string of text and "_SyncRule"). Take a look at the <WriteAction> and you'll see an <MPList>
node that contains a bunch of <MPInfo> nodes. Each <MPInfo> node represents a management pack that was selected in the OM CI Connector wizard.
So, if I understand what you're trying to do, when you import a new MP into Service Manager, you want to add that MP to the OM CI connector's sync list. First; if that MP doesn't exist in OpsMgr, there isn't much point to adding it to the sync list, so I'll
assume you want to add MPs to the sync list that also exist in OpsMgr). Second; there may be other constraints on what MPs you can actually choose in that OM CI wizard and it would be wise to respect those constraints in your own solution. In any case, you'll
have to modify the OM CI connector's rule's write action. There are a couple approaches you can try.
You can try using Microsoft's helper classes that were built for OM CI Connectors (check out the OpsMgrConnectorHelper class and related classes in the Microsoft.EnterpriseManagement.ServiceManager.OpsMgrConnectorUtils.dll.
Also check out the OpsMgr connector wizard classes in the Microsoft.EnterpriseManagement.ServiceManager.UI.Administration.dll).
The other possible approach is to modify the connector's rule directly using the SDK's ManagementPackRule and ManagementPackWriteActionModule classes. You can easily get your OM CI connector's rule using the management pack's "GetRule" method (or the EnterpriseManagementGroup's
Monitoring.GetRule method). The management pack rule has a "WriteActionCollection" which is a collection of ManagementPackWriteActionModule objects. There should be only one ManagementPackWriteActionModule in an OM CI rule's write action collection.
This object has a "Configuration" property..it contains a giant block of XML that holds all of the <MPInfo> nodes I mentioned earlier. So, you can modify that block of XML, then write the changes back to the management pack using the management pack's
AcceptChanges() method. Here's the basic structure: 
ManagementPack mpLinkingFramework = emg.ManagementPacks.GetManagementPack(new Guid("50DAAF82-06CE-CACB-8CF5-3950AEBAE0B0")); //ServiceManager.LinkingFramework.Configuration
ManagementPackRule mpr = mpLinkingFramework.GetRule("<my connector's rule's name>");
ManagementPackWriteActionModule mpwam = mpr.WriteActionCollection[0];
String myConfig = mpwam.Configuration; //This is the XML block you want to update
myConfig = "<a modified configuration with my new <MPInfo> node>";
mpwam.Configuration = myConfig;
mpLinkingFramework.AcceptChanges();
Please note I haven't personally tried modifying an OM CI connector's rule using this method and I can't promise it will work..you'll definitely want to try it in a test environment first. But I can say I have modified my own connectors (and other write actions)
using this technique and it works fine. I just can't say for sure how it might affect an OM CI connector since I haven't tried it myself.
Though my post here is definitely _not_ a solution, hopefully it will give you some guidance on how you might approach your solution.
Maybe someone else here has personally used the OM CI connector classes and can give you some better insight.
