Hello!

I'm trying to run process from server and then there are an error "com.rapidminer.operator.UserError: Database connection failed: connection MSSQL is unknown. Please define the connection properly."

When i click run process locally it works.

How can i upload connection from studio? or how can i solve this problem.

hello @Ikalaus - you need to create database connections in Server if you want it to use them.  Log into the web interface as admin and then go to Administration -> Database connections.  Set everything up there (including testing) and you should be good to go.

Hello thanks for answer.

I have already created conections in server

I think that maybe there are another solution to create from studio and then atach to server.

hi @Ikalaus - have you saved the process on the server first, and then set the parameters for Read Database?  You have to save the process on the server so that the server database connections will propagate to your Studio database connections.
