Rittman Mead are very pleased today to announce our special edition of Oracle E-Business Suite R12 running on Apache Hadoop and MongoDB, for customers looking for the ultimate in scalability, flexible data storage and lower cost-of-ownership. Powered by Hadoop technologies such as Apache Hive, HDFS and MapReduce, optional reference data storage in MongoDB and reporting provided by Apache Pig, we think this represents the ultimate platform for large deployments of Oracle’s premier ERP suite.
Back in September Mark blogged about Oracle GoldenGate (OGG) and HDFS . In this short followup post I’m going to look at configuring the OGG Big Data Adapter for Flume, to trickle feed blog posts and comments from our site to HDFS. If you haven’t done so already, I strongly recommend you read through Mark’s previous post, as it explains in detail how the OGG BD Adapter works. Just like Hive and HDFS, Flume isn’t (more...)
Deleting some rows or tens of millions of rows from an Oracle database should be treated in a completely different fashion. Though the delete itself is technically the same, maintaining indexes and validating constraints may have such a time and resource consuming influence that a vast amount of undo and redo is necessary when deleting millions of rows, in contrast to just a bit when you delete some.
A classic recipe in order to limit (more...)
Each year at the Rittman Mead BI Forum we host an optional one-day masterclass before the event opens properly on Wednesday evening, with guest speakers over the year including Kurt Wolff, Kevin McGinley and last year, Cloudera’s Lars George. This year I’m particularly excited that together with Jordan Meyer, our Head of R&D, I’ll be presenting the masterclass on the topic of “Delivering the Oracle Big Data and Information Management Reference Architecture”.

We will be presenting the Sonra Hadoop Quick Start Appliance at CeBIT next week in Hanover. Meet and greet us in Hall 2, Stand D52 (C58).
At Sonra we understand the difficulties faced by businesses when they begin their Big Data journey. We help you get started in days or weeks and immediately reap the benefits of Big Data. Sonra have packaged optimised Hadoop Supermicro hardware with MapR, the prime Hadoop distribution, and added our (more...)
We got excellent feedback for our first Hadoop User Group Ireland meetup. We wined, dined, and entertained more than 100 Hadoopers (and there was even beer left at the end of the night).
If you want to find out more about Sonra’s Hadoop Data Warehouse Quick Starter Solutions you can contact me or connect with me on LinkedIn.
For those of you who missed the event I have posted some pictures below. We have recorded (more...)
Join MapR and Sonra for the Hadoop User Group Ireland Meetup on 23 February at 6 pm at the Wayra offices (O2/Three building). You’ll learn more about the MapR distribution for Apache Hadoop through use cases, case studies and an introduction to the benefits of using the MapR platform.
Come by for this content-packed first event ending with the opportunity to socialise over beer and pizza kindly provided by Sonra.

I have been patching engineered systems since the launch of the Exadata V2 and recently i had the opportunity to patch the BDA we have in house. As far as comparisons go, this is were the similarities stop between Exadata and a Big Data Appliance (BDA) patching.
Our BDA is a so called startes rack consisting of 6 nodes running a hadoop cluster, for more information about this read my First Impressions blog post. On (more...)
Last week I visited the Oracle Business Analytics Partner Update at Oracle NL in Utrecht, the Netherlands. The NL (Pre-) Sales gave us an update of the Oracle Analytics Roadmap. There is a lot of movement in the world of Oracle Analytics. I have written about the publications during Oracle Open World 2014. When we look back…Read more Oracle Business Analytics Update
Presentaties februari 2015
Voor februari 2015 staan er diverse presentaties op de planning met name op het gebied van architectuur en agile:
Kennissesies agile architectuur bij Ordina
Op 5 februari organiseert Ordina een kennissessie over agile architectuur in de praktijk. Net als op het LAC zal ik een presentatie houden over de waarde van architectuur en time-to-market. Waarin ik laat zien dat juist architectuur waarde en snelheid kan bieden bij de time-to-market. Dit aan de (more...)
Data isn't really respected in businesses, you can see that because unlike other corporate assets there is rarely a decent corporate catalog that shows what exists and who has it. In the vast majority of companies there is more effort and automation put into tracking laptops than there is into cataloging and curating information.
Historically we've sort of been able to get away with this
Over six parts I've gone through a bit of a journey on what Big Data Security is all about.
Securing Big Data is about layers
Use the power of Big Data to secure Big Data
How maths and machine learning helps
Why its how you alert that matters
Why Information Security is part of Information Governance
Classifying Risk and the importance of Meta-Data
The fundamental point here is that
So now your Information Governance groups consider Information Security to be important you have to then think about how they should be classifying the risk. Now there are docs out there on some of these which talk about frameworks. British Columbia's government has one for instance that talks about High, Medium and Low risk, but for me that really misses the point and over simplifies the
What does your security team look like today?
Or the IT equivalent, "the folks that say no". The point is that in most companies information security isn't actually something that is considered important. How do I know this? Well because basically most IT Security teams are the equivalent of the nightclub bouncers, they aren't the people who own the club, they aren't as important as the
In the first three parts of this I talked about how Securing Big Data is about layers, and then about how you need to use the power of Big Data to secure Big Data, then how maths and machine learning helps to identify what is reasonable and was is anomalous.
The Target Credit Card hack highlights this problem. Alerts were made, lights did flash. The problem was that so many lights flashed and
In the first two parts of this I talked about how Securing Big Data is about layers, and then about how you need to use the power of Big Data to secure Big Data. The next part is "what do you do with all that data?". This is where Machine Learning and Mathematics comes in, in other words its about how you use Big Data analytics to secure Big Data.

We all know the saying: When the student is ready, the teacher will appear My advice is to empty your cup, daily, so that when the teacher appears you will recognize them. Unless we are humble in our hearts and in our spirit, we are not open to new things and to learning. The teacher […]
In the first part of Securing Big Data I talked about the two different types of security. The traditional IT and ACL security that needs to be done to match traditional solutions with an RDBMS but that is pretty much where those systems stop in terms of security which means they don't address the real threats out there, which are to do with cyber attacks and social engineering. An ACL is only
As Big Data and its technologies such as Hadoop head deeper into the enterprise so questions around compliance and security rear their heads.
The first interesting point in this is that it shows the approach to security that many of the Silicon Valley companies that use Hadoop at scale have taken, namely pretty little really. It isn't that protecting information has been seen as a massively
Every data platform has its value, and deciding which one will work best for your big data objectives can be tricky—Alex Gorbachev, Oracle ACE Director, Cloudera Champion of Big Data, and Chief Technology Officer at Pythian, has recorded a series of videos comparing the various big data platforms and presents use cases to help you identify which ones will best suit your needs.
Riak and Oracle are completely different platforms. Alex explains that “Oracle database (more...)
