Oracle and licenses. The general feeling most of the time is that you pay too much for the use of the Oracle products, and it’s not always sure if you are compliant, because of the complexity of the rules. This – hopefully clarifying – blog is part of a small series and is an updated blogpost of one I wrote a few years ago, published on my private website. Since then the (Oracle) world has (more...)
Virtual Development Server: Add swapfile to VirtualBox as requirement for installing Oracle or build Oracle docker images
As I want later build Oracle docker images, some of this need a swapfile.
Per default my used Vagrantbox, does not have one, so later steps will fail.
As in the last blog I use a Vagrant shell provider.
... # add swapfile to the box config.vm.provision :shell, :path => "add_swap.sh" ...
This calls the script add_swap.sh in the created VirtualBox machine.
Make sure, that you create your swapfile on a supported (more...)

What is the Fourth Industrial Revolution?
We are living days of change.
Some call it the "fourth industrial revolution", some call it "Industry 4.0." Regardless of what you call it, we're seeing the combination of cyber-physical systems (CPS), the Internet of Things and the Internet of Systems.
Previous industrial revolutions liberated humankind from animal power, made mass production possible and brought digital (more...)
Virtual Development Server: Add enough ram and disk space to VirtualBox for further server components
As I want later build docker images and run docker containers I have to provide enough disk space for this.
Per default the Vagrantboxes have vmdk disks, these have a static size and are to small for my purposes.
Therefore I convert the disk, which comes with the box, via Vagrant VirtualBox provider from vmdk to vdi, so that it allocate only the used disk space in the host system.
Additional I add a second (more...)
As I want to decouple my development server from my computer as much as possible I want to create first a virtual machine with linux.
Because I have used Oracle Virtualbox in the past successfully, I will use it here too.
For long time I had the idea to create a virtual development server for testing some ideas and play with some new and old technologies.
The several components should be easy replaceable and should influence my computer as little as possible.
So in the next blogs of this series I will discuss several technologies like vagrant, docker, jenkins and several oracle database and development stacks.
Please stay tuned!

In an ideal world with a well-balanced and high-performing team, theory says it should all be dandy. But what happens when the real world sticks it's nose in and you need to deal with varying degrees of disfunction?

Sooner or later you'll hear someone suspect it must be a problem with CI. Which is ironically funny in a shoot-the-messenger kind of way!
Thankfully our "CI issue" turned into a for-real bug. In short, the code involved many classes with near 100% test coverage. It had been read (more...)
In a previous post I explained what Node.js is and how it works. Now, I’ll help you install it and create your first Node.js powered webpage.
De ranglijst die FD publiceerde is een ranglijst van ranglijsten. Hij is gebasserd op:

APEX Connect 2016 in Germany’s capital Berlin and the DOAG Database days have finally persuaded me to talk more about #DBADev, let me explain why…
Whenever in the stone age…
During my career as DBA, I was always working closely together with Oracle Forms & Reports developers. In retrospect, the cooperation in that time was remarkable.
These Forms & Reports developers had always (more...)
If you need TranslationHub (Windows only) for your forms and reports development and plan to move to one of the following
- 12c Database for your TranslationHub repository
- 12c Forms/Reports (only available for 64 bit Windows)
- higher version of 64 bit 11g Forms/Reports
then please immediately stop! None of this combination works with TranslationHub!

Of course we all know GUI stands for Graphical User Interface, just as CLI stands for Command Line Interface, right!
Or, rather, a GUI is this nice, flashy screen where you can easily roam with your mouse, comparable to a multiple choice quiz, where the right answer is there for the picking.
A CLI on the other hand is this dark, mysterious blinking cursor… Nothing happens unless you know more or less what (more...)
This blog post is inspired on work I have been doing on Standard Edition databases and the returning confusion about what is and what is not part of Standard Edition.
DBA_FEATURE_USAGE_STATISTICS is a tool in determining license usage for the Oracle database. It is good to understand the implications of each entry, know what is happening in your database and thus be able to have a substantial conversation about the usage of your license, being (more...)
Today my presentation is confirmed: “Bob the Builder: Build/Deploy of ADF enterprise applications”.
I will speak over our experiences with following
- build tools
- deployment tools
- versioning & branching
- continuous integration
- hot deployment in development
- compile & runtime dependencies
If you speak german and you are interested in some of this, you should come and attend DOAG 2015.

In this post, we’re going to perform a push button refresh of an Oracle Database, Application Express (APEX) installation, and Tomcat webserver.
“But Oracle Alchemist,” you’re probably thinking, “we know about that. You’ve told us about how Delphix can provision and refresh data.” And yes, you’d be right. But I wasn’t done yet.
We’re going to perform a refresh of an Oracle Database, APEX installation, and Tomcat running in Amazon Web Services, replicated from (more...)
Seamless cloning of an application stack is an outstanding goal. Seamless cloning of an application stack including the full production database, application server, and webserver in a few minutes with next to zero disk space used or configuration required is the best goal since Alexander Graham Bell decided he wanted a better way tell Mr. Watson to “come here.”
Last week I attended Oracle OpenWorld 2014, and it was an outstanding event filled with great people, awesome sessions, and a few outstanding notable experiences.
Personally I thought the messaging behind the conference itself wasn’t as amazing and upbeat as OpenWorld 2013, but that’s almost to be expected. Last year there was a ton of buzz around the introduction of Oracle 12c, Big Data was a buzzword that people were totally excited (more...)
Are you going to Oracle OpenWorld 2014? I am, and I hope to see you there! As you probably know, OpenWorld is a humongous event with tens of thousands of people in attendance and some amazing presentations. Why, I even hear Oracle’s new CTO might be there. I wonder if he has anything to talk about?
This year we’ll have a ton of activity at the Delphix booth. You can check out the speaking schedule, (more...)
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:
- db file scattered read – Scattered reads aren’t always full table scans, and they’re certainly not always bad.
- Parse to Execute Ratio – This is not a metric that shows how often you’re hard parsing, no matter how (more...)
