Whatever next? The battle to keep up with changes in technology

I’ve been managing Rittman Mead’s Training services in the UK & Europe for over a year now, working closely with my colleagues in the US to ensure we continue to coherently deliver expert instructor led educational courses to the very highest standards.

One thing I’ve noticed is that while a great deal of value is gained by attending instructor led training, particularly if you’re upgrading or installing a new product to your data platform, you (more...)

Oracle Text, Oracle R Enterprise and Oracle Data Mining – Part 5

In this 5th blog post in my series on using the capabilities of Oracle Text, Oracle R Enterprise and Oracle Data Mining to process documents and text, I will have a look at some of the machine learning features of Oracle Text.

Oracle Text comes with a number of machine learning algorithms. These can be divided into two types. The first is called 'Supervised Learning' where we have two machine learning algorithms for classification type (more...)

Performing a 12c Upgrade with a New Install

Software updates often include new features, and while useful, these new features are often the only driving factors in upgrading software. There's no harm in wanting to play around with the shiny new toy but many software updates also include much more significant changes, such as resolving bugs or security vulnurabilities.

In fact, bug fixes and security patches are usually released on a more frequent schedule than new feature sets. These changes are necessary to (more...)

Our first OUG Ireland Meet-up

Last Thursday evening (20th October) we had our first Meet-up event for OUG Ireland.

Up to recently we have had a one or two full day SIG events that covered both the Tech and BA/Big Data areas. But we have been finding it increasingly difficult to get speakers and attendees to take a full day out of work to attend the SIG events. This was particularly true for a SIG event we had scheduled to (more...)

Oracle OpenWorld 2016 – Data Integration Recap

I know it's been about a month since Oracle OpenWorld 2016 concluded, but I wanted to give a brief recap on a few things that I thought were interesting in the data integration space. During the week prior to OpenWorld, I had the privilege to attend the Oracle ACE Director Briefing. Over 2 days, ACE Directors were provided an early preview of what's to come down the Oracle product pipeline. The importance of the event (more...)

Oracle Data Miner (ODMr) 4.2 Repository Upgrade

With each new release of the Oracle Data Miner (ODMr) tool (part of SQL Developer) an upgrade of your ODMr Repository is needed. This is because of the numerous new features in the tool. This is particularly the case with ODMr (SQLDev) 4.2.

No most of the new features for ODMr 4.2 will not be visible until you are running a 12.2 Database. But a small number of new features are available (more...)

Oracle Data Visualisation License Pricing

OTN Appreciation Day : My favourite thing from OTN #ThanksOTN

This blog post is my contribution to the OTN Appreciation Day, the brain child of Tim Hall (read his blog post here).

For my contribution, I'm going to write about something that is a bit different to what most people will be writing about. Most people will be writing about some feature of the Oracle Database or maybe their favourite tool.

I'm not going to do that. What I'm going to write about (more...)

OTN Appreciation Day : Dual Table

I have been working with Oracle products for about 20 years now. One of the great things about Oracle is the Oracle Community. Central platform within this community is the Oracle Technology Network (OTN). I have been frequenting OTN loads of times (downloading software, exchanging knowledge on the forums, etc. ). A lot of people … Continue reading "OTN Appreciation Day : Dual Table"

Oracle Data Miner 4.2 EA : New Features

A couple of weeks ago during the madness of Oracle Open World there was some new product releases and lots of updates to existing products.

One such product was SQL Developer. They released an Early Adopter version (EA1). This is where you can try out the new version of the product, but you need to be careful as it is not the GA/Production version. So it may have some "features".

One component of SQL Developer (more...)

Machine Learning notebooks (and Oracle)

Over the past 12 months there has been an increase in the number of Machine Learning notebooks becoming available.
What is a Machine Learning notebook?
As the name implies it can be used to perform machine learning using one or more languages and allows you to organise your code, scripts and other details in one application.
The ML notebooks provide an interactive environment (sometimes browser based) that allows you to write, run, view results, share/collaborate (more...)

Thoughts/Info on Essbase/EssCS after Oracle Open World 2016

I was at Oracle Open World last week and have some notes to share on the upcoming EssCS (Essbase Cloud Service) product and on Essbase in general.

EssCS will be Infrastructure as a Service (IaaS) product and will be priced on the number of cores and memory.  I believe there will be a metered and an unmetered pricing as well (metered meaning pay per cycle or some other usage measure).  According to presentations at Open (more...)

Wat hebben kippen en de Cloud met elkaar gemeen? (Dutch)

Binnen de BIWA SIG worden diverse onderwerpen en thema’s behandeld binnen de vakgebieden Business Intelligence (BI) en Data Warehousing (WA). In Oracle termen vertaalt zich dat in Business Analytics en Data Integration. Wilt u het antwoord weten op bovenstaande vraag? Kom dan naar de eerstvolgende BIWA SIG (Special Interest Group) meeting van de OGh. Tijdens deze avond … Continue reading "Wat hebben kippen en de Cloud met elkaar gemeen? (Dutch)"

How to Display a BLOB image in an APEX Report

Do you want to display an image on a report in APEX ?

Is the image stored as a BLOB data type in your schema or the blob is returned by some functions?

If so, then displaying the BLOB is not a simple or straight forward task.

Actually it is a simple and straight forward task, as long as you know "the trick" you need to create/defined in your APEX report.

The following steps outlines what (more...)

Separate the Signals from the Noise

Earlier this year I wrote two blogposts about the publication of Gartner’s Magic Quadrant for Business Intelligence and Analytic Platforms. So Oracle did not make it to the Magic Quadrant for Business Intelligence and Analytics Platforms? BI & Analytics Market – Agile BI and / or Enterprise Reporting? Without choosing sides between Gartner or Oracle, … Continue reading "Separate the Signals from the Noise"
