You’ve finished the design for an Apex application, and the manager asks you “when will you have it ready to test”. You resist the temptation to respond snarkily “how long is a piece of string” – which, by the way, is often the only appropriate answer if they ask for an estimate before the design work has started.
Since you have a design and a clear idea of what exactly this application will do, you can build a reasonable (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.

We’ve all heard it before. Computers are totally logical, they do exactly what they are told. After all, Central Processing Units (CPUs) are built out of fundamental units called Logic Gates. With perhaps the exception when a stray cosmic ray gets lucky, the circuits in a computer chip and memory act in a totally logical and predicted manner.
And of course, anything built on top of computers will be utterly logical as well. All those (more...)
If you work with JDeveloper 12.1.3 you may missing the return type of methods in completion insight.
For an example you hit CTRL-SPACE after following code
you see that at the start and at the end of the popup the available method names and parameter. If you have worked before with older versions of JDeveloper, you know that there is shown the return type of the method at the end. What a loose of (more...)
Kscope15 promised to be a brand new experience in more than one way.
As I start to write this report, I am flying from Düsseldorf airport to Atlanta. It will be the first time flying to the United States with a stopover, and because of Erik van Roon, I came prepared. With just carry-on luggage, I should end up at my final destination, Fort Lauderdale, Florida, together with my ‘stuff’. I am flying Delta (more...)
For those of you who haven’t been working with on-line data replication; in short, it is a way to copy data from a source database to a target database and do this on-line (both databases are active) and do it near-real-time.
This means that when you enter data in you source database, you can immediately query it from your target database. This makes on-line data replication ideal for numerous tasks, like moving and / or (more...)
Execution Plan Instability – What is the problem?
The Oracle Optimizer is a complex piece of software and with every release it becomes more complex.
In the beginning, the Optimizer was rule-based.
The Optimizer had a ranked list of heuristics used to optimize a query, picking the lowest ranked rule available.
This rule-based mode, whilst still in use with some internal Oracle dictionary queries, has been unsupported since version 10.1.
This means that (more...)

Today I’m talking about the importance of setting up your Oracle Service Contract correctly. This will help you comply with Service Level Agreement (SLA) and provide discounts to customers according to the contract they have with your company.

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...)
A few days ago I attended the AMIS UX & UI event.
During this interesting event, Niels Mansveld from AMIS presented about UX Frameworks. And he started off his presentation with an illustration about how user interfaces can create an “experience”, so to say. This illustration was a movie clip by Pixar, taken from the movie “Lifted”. It was so funny and, if you would watch it, you immediately know what Niels meant!
The day (more...)
I was being teased by SQL Developer.
Everytime I started it came nagging about that it was being forced to live in an old Java version called jdk1.7.0_45 and that is was not feeling happy about it.
So, I should remedy this, I thought to myself.
First visit was, inspired by some search-work on the WWW, a file called product.conf. Which offered two possiblities:
SetJavaHome to some logical location
SetJavaHome to (more...)
In doing more work directly from my Macbook Air, I ran into a situation where native connectivity to an Oracle environment was needed.
From experience I have always been a big fan of the Full Oracle client, just because it comes with a lot of tools and utilities for troubleshooting, which makes the actual experience a bit more pleasant.
Looking & asking around, though, I learned fairly quickly that this client is just not (more...)
(blogarhythm ~ Diablo - Don't Fret)
The Fretboard is a pretty simple Arduino project that visualizes the build status of up to 24 projects with an addressable LED array. The latest incarnation of the project is housed in an old classical guitar … hence the name ;-)
All the code and design details for The Fretboard are open-source and available at fretboard.tardate.com

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.”
So in the spirit of discovery, I’ve installed Oracle REST Data Services (ORDS) 2.0 (more...)
Sometimes development is just work
No matter how cool your job is, no matter how many people are looking at you or your company for best practises, sometimes developing software is just work On this blog I’ve shared examples of companies that people nowadays see as successful, like Netflix, Twitter, Spotify, or the online retailer bol.com.
To prove my point I’ve checked the release notes of Netflix and Spotify apps. Here (more...)
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...)
Some days before ZeroTurnaround has released XRebel , a new tool to recognized problems in your web applications, when you make your developer test.
This was promising, so I give it a short try for Oracle ADF applications. For this blog I use the Summit ADF application, delivered by Oracle, but I have tried with our own application too. Test is done in JDeveloper 12.1.2.
After the download there are some easy steps (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...)
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...)
