Description
The service being published requires its data to be copied to the server-side enterprise geodatabase. This is the case when publishing feature services or transaction-enabled WFS (WFS-T) services. The server-side publishing tool was unable to connect to this database.
This server system tool is invoked by the publishing client (for example, ArcGIS Desktop) when you create a service.
Solution
Verify that the server has a server-only enterprise geodatabase correctly configured. If the service type you want to publish requires an enterprise geodatabase, you must first create an enterprise geodatabase on the server and register it as an ArcGIS Server Managed Database.
