Hello I am trying to take the Oracle Middleware 12c: Build Rich Client Application with ADF training.

I cannot make it past the database connection part of the training. I am getting an IO Error. Should I have some sort of database set up or is there somewhere I can get a practice database? The instructions do not provide any answers to this.
