From time to time someone publishes a query on the OTN database forum and asks how to make it go faster, and you look at it and think it’s a nice example to explain a couple of principles because it’s short, easy to understand, obvious what sort of things might be wrong, and easy to fix. Then, after you’ve made a couple of suggestions and explained a couple of ideas the provider simply fades into (more...)
“Als je het niet kan zeggen, zing het dan maar”. Dat was vroeger een veel gebruikte kreet als je niet onder woorden kon brengen of kon benoemen wat je wilde zeggen. Hier moet ik vaak aan terugdenken als ik de fantastische kretologieën voorbij zie komen die nieuwe trends of hypes in onze mooie IT wereld beschrijven. Soms iets van oude wijn en nieuwe zakken of door alleen het oogstjaar te veranderen, maar vaak zijn de (more...)

We had the same setup for every evening: First, Sebi was talking about JBoss Tools and Forge and showed how to quickly create a Java EE based backend. Afterwards the audience saw the how to create a good looking Apache Cordova mobile app, that he also generated using Forge! At the end the solution (more...)
I have a bone to pick with UKOUG. I’m coming from Birmingham and I’m a lazy git, so why the heck am I on in the first slot? It was a 04:30 start to the day, for a train journey starting at 05:50. I could have got a later train, but it would have been busier and more importantly, more expensive… After putting the latest of my writing tips posts live and lying in the (more...)
Last week, I wrote about how to use
bash arrays and the MySQL database to create unit and integration test scripts. While the MySQL example was nice for some users, there were some others who wanted me to show how to write
bash shell scripts for Oracle unit and integration testing. That’s what this blog post does.
If you don’t know much about bash shell, you should start with the prior post to learn about (more...)
We are discussing the management of Oracle Database 12c in Oracle Enterprise Manager 12c. In our previous blog post on this topic, we discussed the new Enterprise Manager Database Express 12c, which is the replacement for the earlier Database Control (used in previous versions of the Oracle database such as 11g and 10g, to manage a single database).
I’m a Jedi master at writing off-topic posts! This blog started life as an Oracle blog, but now I just write reviews of Twilight and 50 Shades of Grey.
The simple answer is you should do what you are happy with. I had been writing on my website for 5+ years before I started this blog. When I started the blog, I thought it would be technical. It quickly became apparent that the Oracle content was better (more...)
We are discussing the management of Oracle Database 12c in Oracle Enterprise Manager 12c. In our previous blog post on this topic, we briefly looked at the changes for Metering and Chargeback. We will now look at the new Database Express 12c.
An Oracle employee sent me an email today, inquiring about the Open Mic Night. This employee, who is a user of Oracle Application Express at Oracle, (more...)
Installation was not bad.
Evodesk is the 2nd company I am aware of for using recesss nuts for desktop installation.
This makes much more sense than using wood screws.
However, pondering if Evodeskk will be the first company to used recess nuts for all components and get rid of wood screws.
Don’t you think the legs make great towel rack?
This is very cool:
There are a bunch of nice computer science classes online from mit: Free online MIT computer science classes
Here is an introductory computer science class: Intro to computer science
Here is a graded version of the same class on edX: Graded version of MIT intro CS class starting June 10th.
edX does not have as many computer science classes but edX may motivate students because edX classes include grades and certificates for those who (more...)
Let’s conclude this series of articles on database security by reviewing what we learned in previous installments. Along the way, I’ll provide some additional hints and tips to tie everything together.
We learned that database administrators, since the inception of their job descriptions, have been responsible for the protection of their organization’s most sensitive database assets. This envious responsibility will not change. As DBAs, we will be forever tasked with ensuring that our critical (more...)
In every universe there are questions that either:
Have no answer
Have an answer that is situation-dependent
and that includes the Oracle universe. Sometimes it’s difficult to get that concept across to the less knowledgeable. Let’s go back to a simple example from a previous post to illustrate this.
In Resurrecting The Dead flashback operations were discussed as an option to restore table data to before an errant update. The post started with this:
First, I've pushed the limits of my iPad's usability. I really have...for a couple of years. But I just don't find myself using it for any kind of serious work. My MacBook Air has really taken over for both premise-based and cloud-based work. Even (more...)
Part III – There’s Something (Profitable) About Your Privacy
Why do so many companies hanker after apps? Smartphone apps, tablet apps, iOS apps, Android apps, app-this, app-that….
Leave aside for a moment the techno-pubescent excitement that accompanies the launch of every new technology (if you are not old enough to remember words like “client-server”, then “soa (more...)
I’m excited to announce the first acquisition by Delphix (portending many to come). Dephix has just acquired the data masking company Axis Technology Software. Delphix is integrating the Axis masking technology into the core Delphix product. Masking is a feature that 9 out of 10 customers have asked for after buying Delphix. Delphix eliminates the data cloning bottleneck for application development environments and naturally the next concern that arises is how to mask the data from production (more...)
