I create a database.
I define a connection with a system DSN to an Oracle Database. The system DSN is using the oracle driver. And I successfully test the connection.

I add a few tables to my database.

I go to the upsizing wizard. I choose and open my database.

When I get to the "Select Data Source" step No matter what I do, there are either:

"No Connections Defined." or "No datasources defined."

What am I doing wrong?
