Oracle Machine Learning Users on ADWC

One of the new features of the Autonomous Data Warehouse Cloud (ADWC) service is Oracle Machine Learning. This is a Zeppelin based notebook for your machine learning on ADWC. Check out my previous blog post about this.

In order to be able to use this new product and the in-database machine learning in ADWC, you will need your database user to have certain privileges. The first step in this is to create a typical user for accessing the ADWC and grant it the necessary OML privileges.

To do this open the ADWC console and then open the Service Console.



This will then open a new admin page which contains a link for 'Manage Oracle ML User'. Click on this.



You can then enter the Username, Password and other details for the user, and then click Create.
This will then create a new user that is specific for Oracle Machine Learning. This new user will be granted the DWROLE, that contains the basic schema privileges and the privileges required to run the in-database machine learning algorithms. For those that a familiar with Oracle Data Mining/Oracle Advanced Analytics option in the Enterprise Edition of the Oracle database, you will see that these privileges are very similar.

You can examine the privileges granted to this DWROLE in the database as an administrator. When you do you will see the following:

CREATE ANALYTIC VIEW 
CREATE ATTRIBUTE DIMENSION 
ALTER SESSION 
CREATE HIERARCHY 
CREATE JOB 
CREATE MINING MODEL 
CREATE PROCEDURE 
CREATE SEQUENCE 
CREATE SESSION 
CREATE SYNONYM 
CREATE TABLE 
CREATE TRIGGER 
CREATE TYPE 
CREATE VIEW READ,WRITE ON directory DATA_PUMP_DIR 
EXECUTE privilege on the PL/SQL package DBMS_CLOUD
