I’m going to create a new Cloud VM to host some of my machine learning work. The first step is to create the VM before installing the machine learning software.

That’s what I’m going to do in this blog post and the next blog post. In this blog post I’ll step through how to setup the VM using the Oracle Always Free cloud offering. In the next I’ll go through the machine learning software install (more...)

    There are a number of different ways to load data into your Autonomous Data Warehouse (ADW) environment. I’ll have posts about these alternatives.

    In this blog post I’ll go through the steps needed to load data using Object Storage. This might appear to have a large-ish number of steps, but once you have gone through it and have some of the parts already setup and configuration from your first time, then the second and subsequent (more...)

    Oracle Autonomous Database (ADW) has been out a while now and have had several, behind the scenes, improvements and new/additional features added.

    If you have used the Oracle Machine Learning (OML) component of ADW you will have seen the various sample OML Notebooks that come pre-loaded. These are easy to open, use and to try out the various OML features.

    In this blog post I’ll give some examples of how to process data for inserting into a table in an Oracle Database. I’ve had some previous blog posts on how to setup and connecting to an Oracle Database, and another on retrieving data from an Oracle Database and the importance of setting the Array Fetch Size.

    When manipulating data the statements can be grouped (generally) into creating new data and updating existing data.

I’ll give some examples that include setting up the query as a prepared statement and how to run a query and retrieve the first record returned. Another version of this last example is a query that returns one row.

    | Jul 26, 2018

    In the last days, I am running a number of tests based on the TPC-DS benchmark against Oracle’s Autonomous Data Warehouse Cloud service (ADWC). One of the first thing I did is of course to create the TPC-DS schema and populate it. The aim of this blog post is to share some observations related to the population step.

    I started by generating the data with the tool provided by TPC-DS: dsdgen. With the following command, (more...)

    Which Privileges Are Required to Use the ADWC Service Console?

    | Jul 17, 2018

    The Autonomous Data Warehouse Cloud (ADWC) service provides a Service Console that can be used to monitor the service activity and to carry out a small number of administration tasks (e.g. changing some resource management rules).

    The documentation specifically says to use the ADMIN user to login. But, actually, any unlocked database user having the CREATE SESSION privilege can be used to login. This is not only useful, but, in my opinion, necessary. In (more...)

    The Appendix A of the Using Oracle Autonomous Data Warehouse Cloud guide describes the DBMS_CLOUD package. Unfortunately, it documents only a subset of the subroutines. And, for some of them, the description could also be enhanced. Therefore, while I was testing all the subroutines the DBMS_CLOUD package provides, I took a number of notes. By the end of my tests, I got what I can call my personal reference guide to the package. Since it (more...)
