Here’s a little tip that’s not particularly brilliant, but just useful, as you start working with the new application model in SharePoint 2013. You always need a subscription settings service application, but it’s one of those things that you cannot create in the UI. So just keep a bookmark to this post and come back as needed for a little copy and paste. This brief PowerShell snippet will create service application and proxy in one fell swoop:
New-SPSubscriptionSettingsServiceApplication -ApplicationPool "SharePoint Web Services Default" -Name "Subscription Settings Service Application" -DatabaseName "SubscriptionSettingsDB" | New-SPSubscriptionSettingsServiceApplicationProxy
Once you’ve created the Subscription Settings service application, you can go configure your application domain in Central Admin.
So you need one of these even if you are not doing multitenancy?
I am running into same question. In 2010 this server is only started for Multi-tenant environments (per technet.microsoft.com/.../ff627854(v=office.14).aspx ). If I am reading this correct, this is no longer the case and must be started for user with Apps form the app store? Is this correct?
