Can you keep up? Nike couldn’t

Nike have been producing the Nike FuelBand for a couple of years, but have recently thrown in the towel. I own a Nike FuelBand and have enjoyed the fact that it’s pretty unobtrusive (just a matte black rubber wristband until you press the button).

I’ve found that the gamification aspect – you are this close to your daily goal, shown with little colored lights – worked well for me. There is a sync feature with (more...)

APEX 4.2 Best Practices Training am 26.05-28.05.2014


Wußten Sie schon, daß in APEX 4.2 alleine 130 neue Features implementiert wurden, die uns Entwickler SOFORT produktiver werden lassen und das Leben erleichern?

Auch wird jedes Release von APEX immer sicherer, es kommen immer wieder neue Security Features hinzu.

The people behind the NoCOUG Journal

Now in its 28th year, the NoCOUG Journal is the oldest Oracle user group publication in the world. No other small user group in the world has a printed journal. Most large user groups do not have printed journals either. But little NoCOUG does. I am the editor of the NoCOUG Journal and—I must confess—I get sad when I see […]

Don’t Fear the EM12c Metric Extensions

A few weeks ago, our customer support team asked us to automate part of their checklist that looks at the number of active sessions in our production database. In EM12c, this seemed like a no-brainer with the Average Active Sessions metric. So I added this to my production incident ruleset and went back to another project. Over the next few days we'd get pinged by EM12c but the support folks would say it shouldn't. After (more...)

Hacker-proof key

At my hotel in London this week, I received a physical key, not a key card. In a time where millions of hotel door locks can be opened by any half-competent hacker with an Arduino microprocessor, it was reassuring to receive a security service that is actually hard to break.

Are you using appropriate technology? Remember that your fancy computer systems are sometimes much more vulnerable than the systems they replace.

Data Lakes will replace EDWs – a prediction

Over the last few years there has been a trend of increased spending on BI, and that trend isn't going away.  The analyst predictions however have, understandably, been based on the mentality that the choice was between a traditional EDW/DW model or Hadoop.  With the new 'Business Data Lake' type of hybrid approach its pretty clear that the shift is underway for all vendors to have a hybrid

Troubleshoot: ora-600[kcrf_resilver_log_1] & ora-600[4193]

El sábado último recibí una llamada mientras manejaba, estacioné y atendí la llamada, se trataba de un buen amigo y cliente que tenía un problema con una de sus bases de datos. Ocurrió que como parte de un mantenimiento al servidor en el cual operaba, uno de los discos había presentado errores para ser reconocido. Eventualmente dieron con la causa del problema y lo resolvieron, el disco era nuevamente reconocido pero la base de datos (more...)

Get the HAPPIEST Job on Earth!

Have you ever met one of those rare breed of people who is unusually fond of his/her job and, says, TGIM (Thanks God its Monday) instead of TGIF (Thanks God its Friday)? Chances are he/she is a DBA (database administrator). Most of us already know that the DBA position can be a very rewarding career. […]

Cycle4Sam 5 – Riding 1000km in 6 days for $100k for Women’s and Children’s Hospital



I recently participated in a week long charity bike ride called Cycle4Sam, where funds are raised to support the palliative care unit at the Women and Children's Hospital of South Australia.

The ride is conducted on a bi-annual basis in honour of young Sam Roberts, who sadly passed away from a rare genetic disease at the age of 4. His parents, Marty and Michelle and his siblings Lucy and Charlie, created the Sam Roberts Family (more...)

Cross Posted from my Personal Blog

I managed to get through high school and college never taking a second language, even in the ’80s this required advanced maneuvers through the academic handbook.  Why would I do this?  Was I against taking a language?

Nope.  I desperately wanted to take a language, but I lacked confidence.

The only language offered in my high school was Spanish, and I wanted to take French or Japanese (it was the ’80s).

DIY Disasters

When people take on home renovation “Do-It-Yourself” projects beyond their skills, disaster ensues. Apparently, this is so common that you can base a whole TV series on this theme – where professionals rescue the disastrous DIY project for the grateful and clueless amateur handyman.

I’ve seen the same thing happen in many IT projects. The people in the organization overestimate their own skills and are unable or unwilling to pay the cost of professional external (more...)

I Love Logs

It occurred to me a few days ago, as I was reading this article on DevOps, that I might actually be a DevOps.

I think of myself as a developer, but my current role is in a small team running a small system. And by running, I mean that we are 

  • 'root' and 'Administrator' on our Linux and Windows servers
  • 'oracle / sysdba' on the database side, 
  • the apex administrator account and the apex workspace (more...)

The Step-by-Step Guide to Migrating to an Exadata Database Machine

We have migrated a number of our databases from non-Exadata servers to the Exadata Database Machine using the “RMAN 11g Duplicate standby from Active database” method. After creating a Dataguard Database, during a narrow maintenance window, we performed a failover of the database to the one Exadata Database Machines in the cluster. Below are the […]

Supplemental Logging and Securefiles Causing DBWn to Block

A few weeks back, we began making changes to prepare for using Oracle Golden Gate. One of the first steps required is to enable "minimal supplemental logging" at the database level. We did this during an evening maintenance window. However by the time the morning workload picked up, we started seeing a lot of sessions blocking, and the root blocker was one of the DB Writer (DBWn) processes.

Looking at the blocked sessions, a query (more...)

OSP #3a: Build a Standard Cluster Platform

This is the fifth article in a series called Operationally Scalable Practices. The first article gives an introduction and the second article contains a general overview. In short, this series suggests a comprehensive and cogent blueprint to best position organizations and DBAs for growth.

We’ve looked in some depth at the process of defining a standard platform with an eye toward Oracle database use cases. Before moving on, it would be worthwhile to briefly touch (more...)
