Oracle Enterprise Pack for Eclipse (12.1.1) available
Shortly after WLS 12c Oracle also has released OEPE 12.1.1 – Oracle Enterprise Pack for Eclipse. It is certified on Windows 7/XP/Vista, MacOS, and Linux. OEPE is supported on JDK 6.
Update: WebLogic 12.1.1 VirtualBox Appliance available
With OTN Virtual Developer Day a WebLogic 12c VirtualBox appliance became available. On the appliance there are Labs and other Java development tools like: Hudson, Subversion, Maven, NetBeans IDE, and Eclipse (including OEPE).
Update: Updated/Patched WebLogic 126.96.36.199 distribution available
Just read Markus Eiseles blog on an updated WebLogic Server 12c on OTN. If you obtain the updated product distribution for WebLogic Server 12.1.1 after March 16, 2012, the patches are included. If you obtained a product distribution for WebLogic Server 12.1.1 prior to March 16, 2012, and you do not wish to re-install with the updated WebLogic Server distribution, you can obtain the patches from Oracle Support.
Still wanted to share some thought and ideas with you I took from the LAC 2011 – the largest symposium in The Netherlands on architecture in the digital world. The larger part of this post is taken from the key note on Speed and Innovation through Architecture by Jan Bosch. He states:
Speed trumps any other improvement R&D can provide to the company.
Speed and time to market deliver far more value than increasing the efficiency of a process. This especially holds for non-repetitive process like (software) product creation. To increase the speed and reduce time to market we should focus on the following aspects:
- Small teams
- Release process
Small teams work on the people side because a team member can experience the fruits of his or her individual efforts while on the other hand they contain the rewarding social element of camaraderie. Both are necessary for people to see their work as fulfilling.
On the process side, small teams increase speed because of the lowered need for coordination within the team and the existence of complexity. A team larger than three is required because of the need to learn from each other, the ability to deliver significant work and enable preservation of knowledge from the feedback the team has encountered. To get speed in the team at a high level the team needs to be self directed and managed.
Architecture – Keep it simple
First and foremost make sure your architecture enables you to simplify things! Keep in mind that rules and constraints can create complexity. And that is something you wanted to avoid when you started with architecture in the first place.
Architecture provides simplicity, compositionality and is designed in parallel with software development
An example would be to limit the number of things a team has to worry about during development. This could be done by applying the 3 API rule and there are other ways as well. Allways ask the questions whether the architecture enables the development team to perform.
In order to get speed into your development process you need to know/measure what people do, not what they think. Factor out opinion and chose data. To get proper results here you need a short PDCA cycle. Check and measure to get results back into your development process. This requires that you release early and often. Which in turn demands automated deployment and test.
While doing some research on the web I came across a Service Component Architecture Diagram Generator. The script generates diagrams for applications based on the Service Component Architecture (SCA) model. This can be a great aid to understand the relations between components in large BPEL or SOA applications.
Download the tool here. The readme is over here. The script runs on Linux/Unix and has primarily been tested with Oracle Fusion Middleware 11g applications but should work with other BPEL or SOA frameworks.

While the NoSQL Database Community Edition still waits for final license approval, Oracle has released it’s NoSQL Database, Enterprise Edition 1.1.100. The download is available on OTN.
The Oracle NoSQL Database is a distributed key-value database. It is designed to provide highly reliable, scalable and available data storage across a configurable set of systems that function as storage nodes.
The documentation page is still rather empty. However Technical Overview and a Data Sheet are already available.
Oracle NoSQL is a key offering in Oracle’s portfolio of Big Data products. The product is based on the Java version of Berkeley DB, an open source database used in embedded systems.
Just uploaded the presentation I gave at the Seminar “Lean & Agile IT: beter resultaat, betrokkenheid en IT volwassenheid” (Dutch) on Lean Integration. Besides the aspect of getting a lean process to create integrations we also focused on how integration is lean in the sense that it can create value.
Just found out that there is a new site for SOA Suite 11g sample code. It is availble on Java.Net. Check it out for great examples.
Since I had to test some webpages with IE6 (please don’t ask), I wanted to use Windows XP Mode on my Windows 7 laptop (actually run it in VMWare as described here). Microsoft provides virtual machines (vhd files) to run in Microsoft Virtual PC.
Rolling back the update
Windows Virtual PC for Windows 7 is released as an update for Windows 7, and has the Knowledge Base Article ID of KB958559. So I tried to install it. That went actually pretty well until I had to reboot my laptop. At about 98% of the update process during the reboot it gave an error and rolled back the update. The log showed:
Installation failure: Windows failed to install the following update with error 0x80004005: Update for Windows KB958559
Digging into the support forums and blog posts on the subject, the most common working solution I found to the problem was to uninstall VMWare and/or VirtualBox. After the uninstall you can install Virtual PC without the error and after that reinstall VMWare and/or VirtualBox.
An earlier post on how cookies are used to track you, explained how tracking cookies work. This post will show you how to stop websites from tracking you using Firefox 4. This latest release has a Do-not-track feature that lets you tell websites you don’t want your browsing behavior tracked.
By turning on the Do-not-track feature, Firefox tells websites you visit that you don’t want your browsing behavior tracked. Please note that honoring this setting is voluntary. To put it differently websites are not required to respect it.

There is a small note in the JDeveloper 188.8.131.52 Installation Guide:
This release of Oracle JDeveloper supports the 64-bit versions of Windows and Java.
More on the question What is 64-bit Java?, can be found on this Java Hotspot FAQ.
The Installation Guide mentioned before doesn’t show additional details on How-To get JDeveloper working on Windows 7 with an 64 bit Java version….
To get this working:
- Download and install a recent 64 bit JDK for Windows 7 64 bit, eg
- go to the
$Middleware_Home$\jdeveloper\jdev\bin directory and edit the
- Alter the
SetJavaHome to the directory in which you just installed the JDK:
# Directive SetJavaHome is not required by default, except for the base
# install, since the launcher will determine the JAVA_HOME. On Windows
# it looks in ..\..\jdk, on UNIX it first looks in ../../jdk. If no JDK
# is found there, it looks in the PATH.
SetJavaHome C:\Program Files\Java\jdk1.6.0_24
- And then start the
jdev64W.exe in the
