Working through Getting to Know ArcGIS Enterprise book from Nov 2025. Chapter 11, tutorial 11. Page 146 seems to imply that you would be connecting to some kind of Esri tutorial database. This doesn't work and I connected myself to an existing "test" database I have. Later in the chapter (page 152) it definitely seems I should be connected to some other database that is not registered and the exercise goes through registering the database with server. Can someone please explain if we are supposed to be able to connect with this MCountySQL instance?
