Before you start data mining, ensure the following:
Specify a connection to an account in an Oracle Database 11g Release 2 (11.2.0.1) or Oracle Database 12c Release 1 (12.1). The account that you connect to must have all grants required by Oracle Data Mining.
Define at least one connection to indicate the account where workflow nodes run.
