OraNA :: Oracle News Aggregator

The UKOUG annual conferences commence on Sunday 7th December and run until Wednesday 10th.

Like previous years there are two conferences, one called TECH15 and the other is called APPS15. You might guess what each conference is about!!.

This year these conferences are being held at the same time and in the same venue. But they are separate conferences!.

This year I've been very lucky (or very unlucky) to have 3 presentations at these conferences. (more...)

The world is changing. People are asking for new kinds of rapidly changing data. This has a big impact on Business Intelligence and Information Management as we have known it for a long time. Therefore I look with great interest in Information Management Architectures in general and Oracle BI Solution Architectures in particular.

How has the interest in Big Data, Hadoop, Business Intelligence, Analytics and Dashboards changed over the years?

One easy way to gauge the interest is to measure how much news is generated for the related term and Google Trends allows you do that very easily.

After plugging all of the above terms in Google trends and further analysis leads to the following visualizations.

Now comparing the rate increase for 2-year program

So for the 2 year program, the board rates have remained at the same level compared to the dorm rates.

Now check out the interesting graph for 4 year program below

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...)

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...)

Virginia maintains the summary of Deer kills way back from 1947

The stack bar gives a total view of the killings and how it has grown over the years

 

By comparing the killings on a line chart we see that the female Deer killings has an uptick from 2008 onwards

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 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?

Here is the complete list (more...)

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...)

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...)

Kscope15 abstract submission will close in just a few days and the ODTUG content teams want you!

I am sure there are many of you who have never done a presentation at a conference and may not feel comfortable speaking in public. Well, I have a secret for you, despite the fact that I won the Best Speaker Award at Kscope14, I share your discomfort with speaking. What works for me, however, is that I (more...)

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.

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.

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