That’s … Huge!

Recently I’ve noticed the occasional thread in Oracle newsgroups and lists asking about hugepages support in Linux, including ‘best practices’ for hugepages configuration. This information is out on that ‘world-wide web’ in various places; I’d rather put a lot of that information in this article to provide an easier way to get to it. I’ll cover what hugepages are, what they do, what they can’t do and how best to allocate them for your particular (more...)

So, a Researcher and Six Developers Join a Hackathon

Editor’s Note: Hey, a new author! Colleague and Friend of the ‘Lab, Joyce Ohgi, a principal usability researcher here at Oracle Applications User Experience, joined several of our guys and tall man, all-around good dude and Friend of the ‘Lab, Rafa Belloni (@rafabelloni), to form a super-powered hackathon team last week.

This is her story, as told from the inside. Enjoy.

I earned $600 in a hackathon without writing a single line of code.

It Pays To Be Smart

Exadata is a powerful system, able to provide exceptional performance. Much of this peformance is due to Smart Scans, Exadata’s mechanism for shifting the workload to the storage cells and having them filter and reduce the amount of data the database servers must process. Not every Smart Scan that starts ends up completing, though. Oracle may decide that a different path, one that doesn’t include a Smart Scan, may be more efficient. Certain conditions must (more...)

SQL Developer can’t start because MSVCR71.dll is missing (On Windows)

I have installed SQL Developer (with JDK) on Windows many times before, and almost all the time I receive the system error bellow when trying to execute it by the first time. Due to this, I decided to publish the

Taleo Interview Evaluations, Part 2

So, if you read Part 1, you’re all up to speed. If not, no worries. You might be a bit lost, but if you care, you can bounce over and come back for the thrilling conclusion.

I first showed the Taleo Interview Evaluation Glass app and Android app at a Taleo and HCM Cloud customer expo in late April, and as I showed it, my story evolved.

Demos are living organisms; the more you show (more...)

Taleo Interview Evaluations, Part 1

Time to share a new concept demo, built earlier this Spring by Raymond and Anthony (@anthonyslai), both of whom are ex-Taleo.

Back in April, I got my first exposure to Taleo during a sales call. I was there with the AUX contingent, talking about Oracle HCM Cloud Release 8, featuring Simplified UI, our overall design philosophies and approaches, i.e. simplicity-mobility-extensibility, glance-scan-commit, and our emerging technologies work and future cool (more...)

What A Performance!

Performance is one of the big watchwords in tht IT industry; nowhere is it more often used than in the database arena, and it’s usually not a good sign. End users know nothing, really, of the inner workings of the database yet they are the first to point the ‘finger of blame’ at the database when the processing speed slows or queries take longer than they would like to return data. [For end users performance (more...)

I Guess Wearables Are a Thing

For what seems like ages, the noise around wearable technology has been building, but until recently, I’ve been skeptical about widespread adoption.

Not anymore, wearables are a thing, even without an Apple device to lead the way.

Last week, Noel (@noelportugal) and I attended the annual conference of the Oracle HCM Users Group (@ohugupdates); the Saturday before the conference, we showed off some of our wearable demos to a small group of customers (more...)

Fourfecta! Java, IoT, Making and Raspi

Here comes more Maker content for your reading pleasure, this time it’s an OTN piece on Java and the Internet of Things:

A Perfect Match: Java and the Internet of Things

The piece features lots of Noel (@noelportugal) wisdom, on making, on IoT, on the Raspi and on Java, his own personal fourfecta. If you’re scanning (shame on you), look for the User Experience and the Internet of Things section.

Here’s a very Noel (more...)

Find Us at Kscope14 Next Week in Seattle

Kscope14 (#kscope14), the annual conference of the Oracle Development Tools User Group, affectionately ODTUG (@odtug), will happen next week in beautiful Seattle, June 22 to June 26.

The good people at ODTUG have graciously invited me back as a speaker for the 2014 vintage, and Anthony (@anthonyslai) will be my wingman for our session, Oracle Cloud and the New Frontier of User Experience.

Here are the particulars:

Maker Movement Fuels the Internet of Things

The Java Team recently released a short video compiling selected moments from last month’s MakerCon and Maker Faire. If you recall, we were lucky to be invited to participate in both events, both of which were tons of fun, enlightening and inspiring.

At 0:33 you’ll see the some of the guys hamming it up for the camera, and Jeremy’s (@jrwashley) keynote at MakerCon is featured prominently as a voiceover.

Enjoy.

If you have Google Glass, you’ve probably seen this card a few times.

After a while, you begin to expect the card when your right temple starts to get uncomfortably warm. Apparently, Anthony (@anthonyslai), our resident Glass expert and long-time Glass Explorer, has a protip to handle this problem, two cans of cold soda.

SCN to Timestamp and back

When working with Oracle GoldenGate, understanding the System Change Number (SCN) is important.  The SCN is an internal number maintained by the database that keeps track of the changes made to the database for recovery purposes.  The SCN is also important when working with Oracle GoldenGate.  In many environments, instantiation of Oracle GoldenGate environments require knowing where to start the replicat from.

To find the current SCN for the database, Oracle has made this pretty (more...)

“A Ponderous Chain”

Chained and migrated rows in an Oracle database can seriously impact I/O performance, especially with Exadata. In a ‘normal’ Oracle database [read that as "non-Exadata, non-ASM" database] chained rows, in small numbers where that usually means 1% or less of the total rows in a table, are generally a nuisance. The performance hit they generate in such a situation is small and may not even be noticed by the end users. Add more chained/migrated rows (more...)

The Misfit Shine

Over the past 12 months, the chatter about wearables (glasses, watches, bands, clothing, material) has become too loud to ignore. It almost seems like manufacturers will force consumers to like wearables, like it or not.

There are good uses for wearables, and one of the most common is the fitness tracker.

Although I haven’t worn one myself until recently, I’ve been around lots of people who have, e.g. my wife had an early FitBit, Noel (more...)

Friend of the ‘Lab, Bob Rhubart (@otnarchbeat) recently recorded a segment with our own Noel (@noelportugal) and Sarahi Mireles (@sarahimireles), a UX developer from our Mexico Development Center.

Noel (@noelportugal) is a clever dude. He’s also passionate. If you’ve ever met him, you already know these things.

Although I haven’t yet jumped into Raspberry Pi, despite Noel’s unbridled passion about the little-computer-that-could, I have captured some metadata about it, just from being around him and his passion.

For example, I know the Raspi needs to be shutdown a certain way, or bad things happen. I recall Noel being very specific about (more...)
