Complete Your Oracle Database 10g Certification Before it Retires in March 2015

The Oracle Database 10g exams and credentials listed below retire on March 1, 2015.

Completing a certification path includes passing all required exams, taking any required training and submitting the course form. If your certification path (as noted on the track page) requires submission of a (more...)

The Customer Experience

The Apple Experience

I’m going to kick this post off by taking sides in a long-standing feud.

Apple is amazing.

There. Edgy, right? Okay, so maybe you don’t agree with me, but you have to admit that a whole lot of people do. Why is that?

Millions of big androids

This latest analysis on the population of mobile device technology got me thinking more about the typical sized screen you might encounter as a global web developer.
So it's looking at 2014 Quarter 1 shipment of nearly 280 million smartphones. 81% are now android, only 16% related to Apple - that next iPhone better be (more...)

orclapex Meetup group Vienna

For a long while now I’m having this idea to initiate an APEX group on some social network to bring APEX Fans together and have regular meetings in my hometown Vienna, Austria.

This idea in mind I met Dan McGhan at APEX World 2014 in Zeist, Netherlands. While talking about this and that we discovered that we both are fans of meetup.com which is a platform to organize meeting groups.

Of course we instantly (more...)

Frequently Misused Metrics in Oracle

Lying Businessman

Back in March of last year I wrote an article on the five frequently misused metrics in Oracle: These Aren’t the Metrics You’re Looking For.

To sum up, my five picks for the most misused metrics were:

Business Graph

  1. db file scattered read – Scattered reads aren’t always full table scans, and they’re certainly not always bad.
  2. Parse to Execute Ratio – This is not a metric that shows how often you’re hard parsing, no matter how (more...)

IT Stockholm Syndrome

Shrugging

Random thoughts on a Friday afternoon…

We’ve all got problems. More to the point, every IT department or team has problems of some kind. It’s why we hire consultants, buy products, start long and arduous journeys into the great unknown depths of root cause analysis, and so on.

What fascinates me is the level at which we come to identify with our problems. When I’ve gone into an environment to deliver recommendations, the conversation usually (more...)

APEX 5.0 Early Adopter has arrived

Suddenly a big thunder rolled through the APEX community -> Version 5.0 has arrived in an early adopter version, as published on Joel Kallmans Blog (as usual on a friday, late night over here in europe).

Over the past 10-15 month we saw numerous presentations of what we can expect in APEX 5, and many of us had our own ideas.

As soon as I got word through twitter I applied for a workspace (more...)

The Delphix Alchemist?

Gold

Alchemists are best known for their (completely fictional and entirely ridiculous, but that’s besides the point) amazing ability to turn lead into gold. Let’s face it, there’s a lot of lead in the Oracle world. Bugs, angry developers, metrics that can seem to elude human understanding…but I (more...)

Some Oracle Community News

Group Hug

With all the posts on Hadoop lately I bet you forgot I am an Oracle geek too, huh?

Well, if the name OracleAlchemist wasn’t enough to remind you, I have some news that might. Two big things have happened this week that I’d like to share.

The High Price of Data

Piggy Bank

You’ve purchased servers, storage space, switches, cables, and countless other pieces of hardware. The Oracle licenses are bought and paid for, Enterprise Edition with a few add-ons. All told, you’ve spent a small fortune on this infrastructure. It’s finally time to start up your database and begin using it for (more...)

First glimpse on APEX 4.2.3

apex.oracle.com has been upgraded on Sept 6th 2013 to Version 4.2.3.00.07, which means a release of APEX 4.2.3 is close.

There are no release notes out yet, but what i could see we have three two Packaged Applications:

  • Data Reporter
  • Opportunity Tracker

In APEX 4.2.2 there was a Packaged Application “Service Notifications Administration” which isn’t in 4.2.3 anymore (although it was marked as (more...)

Why use OVM for Oracle Databases

Some time ago I made a benchmark exercise to compare the performance of an Oracle Database running in a bare metal environment versus a virtualized environment to clear some of the main questions our team and clients in Revera have, such as:  Does an Oracle Database performs well on a (more...)

OOW 2012, allá voy!

Cada año se realiza el Oracle Open World, al cual somos cordialmente invitados todos los Oracle ACE. Pero nunca faltaba algún contratiempo (léase proyecto en marcha con plazos ajustados) que me obligaba a postergar mi asistencia, pero al iniciar este año tomé la decisión de asistir sí o sí.

Desde Junio hice la compra de los respectivos boletos de avión, que -gracias a los KM acumulados- me salieron gratis! Y ya que entraba en (more...)
