Taking a Look at the New Oracle Big Data SQL

Oracle launched their Oracle Big Data SQL product earlier this week, and it’ll be of interest to anyone who saw our series of posts a few weeks ago about the updated Oracle Information Management Reference Architecture, where Hadoop now sits alongside traditional Oracle data warehouses to provide what’s termed a “da

Use tree binding accessors to show detail rows

Tree bindings can be very handy, for example to combine details in the same row as the master. Let’s assume we have the following starting point based on the HR schema:

New in Java 8 : Default and static methods in interfaces

Default method’s  (aka Defender methods) in interfaces are new in Java 8. They enable you to define a default implementation of a method in the interface itself.

If an interface is implemented by several classes, it’s hard to add method’s afterwards, as it will break the code and require all implementing classes to define the method as well. Adding a method to the interface, and defining a default implementation for it, will resolve this problem.

Here’s a code example :

GoldenGate and Oracle Data Integrator – A Perfect Match in 12c… Part 4: Start Journalizing!

In this post, the finale of the four-part series “GoldenGate and Oracle Data Integrator – A Perfect Match in 12c”, I’ll walk through the setup of the ODI Models and start journalizing in “online” mode. This will utilize our customized JKM to build the GoldenGate parameter files based on the ODI Metadata and deploy them to both the source and target GoldenGate installation locations. Before I get into all of the details, let’s recap the first 3 posts and see how we arrived at this point.

Simple Ways to Simplify: Quick Fixes to Enhance OBIEE Visuals

Over the past couple of months I worked with a few clients in order to conduct an assessment on dashboard and analysis design. In most cases I was noticing that the dashboards were overflowing with content to the point that there was really no discernible “story” or “flow” to the information. Most of the dashboards were an overwhelming hub of large tables, excess dashboard prompts, and complicated charts and graphs. Many times the client complaints were that the dashboards were not being fully adopted by the user base.

Planning – setting the cell retrieval threshold and interesting hack

If you have been working with planning then no doubt you have experienced the web application JVM crashing at some point which can be caused by a number of different factors, the usual likely candidates are large forms and maybe the most deadly of all is ad-hoc analysis.

When a large form or ad-hoc retrieval is run then there is a possibility that an out of memory error may occur in the JVM, the common errors to be generated in the logs are:

Cloud Computing Workshop in Berlin

A Tad of Cloud Evangelism It’s always a pleasure to travel to Berlin for various reasons. A fortnight ago I was running an AWS/Google/Netflix OSS/Cloud Management workshop for a non-disclosed European Agency. I had about 3 dozens of attendees working at the forefront of technology.     Yesterday a Thank-You letter from their director arrived. “My […]

The Other

It is the nature of short essays or speeches that they can at best explore the surface of an idea. This is a surprisingly difficult task, since ideas worth exploring usually need to be approached with some rigor. The easy use of the speech form is to promote an idea to listeners or readers who already share a common view - that is one reason speeches are effective forms for political persuasion for rallying true believers.

GoldenGate and Oracle Data Integrator – A Perfect Match in 12c… Part 3: Setup Journalizing

After a short vacation, some exciting news, and a busy few weeks (including KScope14 in Seattle, WA), it’s time to get the “GoldenGate and Oracle Data Integrator – A Perfect Match in 12c” blog series rolling again. Hopefully readers can find some time between World Cup matches to try integrating ODI and GoldenGate on their own!
