Approximate Count Distinct (12.1.0.2 new feature)

With the release of the Oracle Database 12.1.0.2 there was a number of new features and options. Most of the publicity has been around the in-Memory option. But there was lots of other features for the DBA and a few for the developer.

One of the new SQL functions is the APPROX_COUNT_DISTINCT(). This function is different to the tradition count distinct, COUNT(DISTINCT expression), in that is performs an approximate count distinct. (more...)

ODMr : Graph Node: Zooming in on Graphs

When Oracle Data Miner (ODMr) 4.0 (which is part of SQL Developer) came out back in late 2013 there was a number of new features added to the tool. One of these was a Graph node that allows us to create various graphs and charts that include Line, Scatter, Bar, Histogram and Box plot.

I've been using this node recently to produce graphs and particularly scatter plots. I've been using the scatter plots to (more...)

Something new in 12c: FETCH FIRST x ROWS

In this post I want to show some example of using a new feature in 12c for selecting the first X number of records from the results set of a query.

See the bottom of this post for the background and some of the reasons for this post.

Before we had the 12c Database if we only wanted to see a subset or the initial set of records from the results of a query we (more...)

github DMCA takedown notices in the rise!

GitHub maintains a list of all DMCA takedown notices along with counteractions and retractions if any.

Analysing all the notices from 2011, it seems that the takedown notices are on the rise.

Year View : Notice the sharp increase in 2014

Quarterly view : Now looking at the quarterly breakup, seems like the takedowns are cooling off in the later quarters.

So who is issuing these DMCA takedowns?

Top 100 analytics companies ranked and scored by Mattermark

Let us move on from Grass Eating Sauropods and talk about who’s who in the analytic space.

For every dime there are dozen analytic companies. Everybody who provides a freaking dashboard is an analytic company. Anybody that merely mentions Google, Facebook, Hadoop etc in the same sentence is somehow into BigData. Haven’t you stumbled across company pages where they claim to be expert in analytics and big data but they want you to schedule a (more...)

Are you ready for Windows 10? Dodeca Is Ready!

Microsoft recently released it first preview version of their next desktop operating system, Windows 10. In our business, we have seen many large companies just migrate to Windows 7 and the general consensus seems to be that Windows 8 is a 'consumer' operating system. In other words, it will be a while before you have to think about Windows 10, but it is our business to be thinking about this now. We have the Windows (more...)

Installing Oracle 12.1.0.2 on Windows 64bit

The following steps are what I did for installing 12.1.0.2 on Windows.

1. Download the Oracle installation ZIP files from the Oracle Downloads page.

DB Install 15

2. Unzip the two 12c downloads files into the same directory.

3. Go to the newly created directory (it is probably called 'database') and you will find a file called setup.exe. Double click on this file.

DB Install 1

After a couple of seconds you will see the Oracle Database (more...)

OOW14 Days 1 through 4 and wrap-up

Leaving some time between the trip home from OOW14 and finishing up the blog post on the 4 official days of the event has had an interesting effect: excellent write-ups of the news and announcements have already popped up, so it's a pleasure to simply link to Mark Rittman's "News and Updates" post for all your needs in that regard.

w00t! One compound word? Mind-boggling!



As a first time OOW participant, when I arrived at Moscone this morning, the sheer size, grandeur and general over-the-top-ness hit me like a brick. Seeing it in pics and on youtube is one thing but experiencing first hand...wow. KScope back in June was a family party in comparison! Which isn't a bad thing by the way

For me, Sunday was all about getting my bearings and participating - (more...)

Oracle OpenWorld 14 Day -1

Saturday was a rather quiet day. After having spent 2 hours on Friday night, trying to get the connectivity working in my hotel room, Friday started out with another almost 2 hours which culminated on a recabling of the room and replacement modem to finally get things working. After that I was able to put the finishing touches to my presentation.

Lunch was...american. Very american. Think 50s-type diner. Think chili-chedder-hot-dog. Think fries. LOVE IT! (more...)

Analytics Hands on Labs at OOW 14

I had an previous blog post listing the various Oracle Advanced Analytics sessions/presentation at Oracle Open World 2014.

After trawling through the list of Hands-on-Labs it was disappointing to see that there was no Oracle Data Mining or Oracle R Enterprise hands-on-labs this year.

But there is a hands on lab that looks are how to use the new SQL for Big Data feature (announced over the summer).

Here is the abstract for the session.

Oracle Advanced Analytics sessions at OOW14
