Federate server / hosting server / portal for arcgis 10.3.1

[AliBarakat]

Hello,

i just federated my server in my portal. (screenshot below)

and in the hosting server i can see my federated server.

But everytime i choose it, it goes back directly yo no hosting server.

Does anyone know how to fix this?

Are you using Data Store for ArcGIS or are you working with another RDBMS?

Do you see any errors in either the server or the portal logs with regard to this issue?

When you publish directly to the GIS Server, are features copied into your server managed database?

In Portal for ArcGIS, you can have any number of ArcGIS servers can be added to it.

To make one of the server as a hosting server in your portal, the hosting server should have "Server Managed Database".

Server managed database either it can be a Enterprise Geodatabase​ or you can configure ArcGIS Datastore​.
