How to get access to SPServiceContext in powershell?

Question

I'm having trouble getting Get-SPServiceContext to return a SiteSubscriptionId that is not a bunch of zeros. I'm using an account 'SP_Sync' and set permissions to

• Farm Administrators group
• User Profile Service App /w Full control
• SPShellAdmin

Is there any other permissions I need?

UPDATE:

I'm trying to access the user profile manager in powershell. All the examples I've seen are loading the context of the site in the userpfilemanager object. I can't seem to find the permissions I need to access this object.

I thought it was related to the SPServiceContext, but I can't actually run the command

New-Object  Microsoft.Office.Server.UserProfiles.UserProfileManager

I'm receiving the error:

New-Object : Exception calling ".ctor" with "0" argument(s): "Value cannot be null. Parameter name: serviceContext" At line:1 char:19 + $profileManager = New-Object Microsoft.Office.Server.UserProfiles.UserProfileMan ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidOperation: (:) [New-Object], MethodInvocationException + FullyQualifiedErrorId : ConstructorInvokedThrowException,Microsoft.PowerShell.Commands.NewObjectCommand

Answer 1

If their is no site subscription then you will get bunch of zero.

SiteSubscriptionId
------------------
00000000-0000-0000-0000-000000000000

But you need the following permissions(few you already have)

• farm admin group
• SPShellAdmin
• DBO rights on the Content Databases

I would run the command under the farm admin account( the account which run the SharePoint Timer services or central admin app pool).
