I am going to show how you would create a WebLogic data source to Pivotal GemFireXD 1.3. In this example I am using the developer edition of Weblogic which known as "Free Oracle WebLogic Server 12c (12.1.3) Zip Distribution and Installers for Developers" You can download / configure it as follows.http://www.oracle.com/technetwork/middleware/downloads/index-087510.htmlNote: I am assuming you have WebLogic 12C running with GemFireXD also running. I am also (more...)
Your applications contain 20-30% dead code that is never executed. Not just commented-out code that programmers have left in “just in case”, but routines never called, branches never executed and screens never displayed.
The cost of software maintenance depends on the size of the code base, but systems with dead code are more expensive to maintain. This is because every time a developer comes across a dead piece of code, he becomes unsure: “I wonder (more...)
I had the pleasure to attend OpenSlava
conference in Bratislava last week. It is a one day event which is comparably new and launched last year. This year it grew even bigger and even expanded to another area at the Faculty of Electrical Engineering and Information Technologies (FEI STU) of Bratislava. And as there are no registration fees for the conference, it is a great chance to catch up with a lot of interesting speakers.
Bratislava is (more...)
On Pivotal network you will find various build packs you can download and apply to PCF and use for your applications outside of the shipped build packs, using the link below.https://network.pivotal.io/products/pivotal-cf
I am going to show how you would take one of these build packs , install it and then consume it from an application. In this demo I am going to use "tc server buildpack (offline) v2.4
The Pivotal Ops Metrics tool is a JMX extension for Elastic Runtime. Pivotal Ops Metrics collects and exposes system data from Cloud Foundry components via a JMX endpoint. Use this system data to monitor your installation and assist in troubleshooting. Below is the tile once installed and available with Pivotal Cloud Foundry Ops Manager
Once installed and configured, metrics for Cloud Foundry components automatically report to the JMX endpoint. Your JMX client uses the credentials (more...)
I stumbled open SQLShell recently as per the URL below. Below I will show how you can connect to Pivotal GemFireXD using SQLShell. I used this to export query results using CSV output.http://software.clapper.org/sqlshell/users-guide.html
Note: Assuming SQLShell is already installed and instructions below are for Mac OSX
1. Create a file in $HOME/.sqlshell/config
as shown below, I just took the sample it ships with. Notice how I have added an alias (more...)
My Oracle OpenWorld presentation “Mastering Oracle ADF Bindings: Advanced Techniques” is now available for download from the OpenWorld web site. In this presentation, I talk about
- Reading the Bindings tab
- Bindings in the ADF lifecycle
- Working programmatically with bindings
- Getting the binding from a component
- Working with dynamic bindings
- Creating a binding programmatically
If you are interested in creating bindings programmatically, you should read Eugene Fedorenko’s blog post on this. He also makes (more...)
When creating a MDM data model, Talend offers you standard constraint possibilities.
You can choose whether fields are mandatory or not by setting the minimum and maximum occurrence. You may also set fixed values for a field.
Sometimes these options aren’t enough: you also want to use custom validations like email validation and URL validation. To solve this kind of requirements, Talend gives the possibility to use validation rules.
To illustrate this, I’ve created the (more...)
Welcome to another episode of my developer interviews. It is my pleasure to introduce Matthias Wessendorf (@mwessendorf
), whom I know since a long time already. We've been working in and around Java EE for quite a while and met again in Red Hat finally.
Matthias is working at Red Hat where he is leading the AeroGear project. Previously, he was the PMC Chair of the Apache MyFaces project. Matthias is a (more...)
Two weeks ago I visited Oracle Open World in San Francisco. A glimpse of my activity during Oracle Open World can be found in this post. If you want to hear more, please visit the AMIS Oracle Open World Review Session at October 16th.
After a one hour delay at Amsterdam Schiphol Airport the airplane with, amongst others, several AMIS employees took of for San Francisco. There we met
It has been a while since my previous post, and I have a very good reason for that. I have been busy, very busy. But now, after a long time of writing and rewriting I can finally announce that my book, Oracle Mobile Application Framework Developer Guide, is available for you to buy. Many thanks to my reviewers Chris Muir, Frank Nimphius and Joe Huang who guided and helped me all the way.
You have heard about the Virtual JBoss User Group before. It is your unique chance to catch up with all kinds of technologies and methodologies presented by well known Redhatters and community members from all around the world. Just a short week ago the vJBUG was live-streaming the Red Hat mini-booth sessions from JavaOne
and we made all of them available for your to watch if you haven't been able to catch up.
Keep an (more...)
Being an ADF developer, off course a lot of my focus and attention went to the ADF related sessions. I left OOW with a mixed feeling about the ADF sessions. On the downside I felt there was not a lot of attention for ADF during the OOW conference. You see ADF or ADF related features during almost all the presentations, whether it is the Cloud, SOA Suite and Service Bus or MAF, but not a (more...)
Since I am fairly new to the Oracle Service Bus I gathered a lot of information about this product. Most of it is not shocking and has been mentioned already, but this gave me a nice summarized overview of what 12c has to offer in comparing to 11g.JDeveloper
Since the 12.1.3 release, you don’t need eclipse anymore to create your service bus projects. Just as for the SOA Suite you can do (more...)
Oracle Open World was once again very inspiring, last week I’ve been summarizing my own notes. I decided to share them with the world, if not only for me to find them back in my own blog archive in the (near) future.
As you might have guessed, there was a lot going on about the cloud. So much, it was almost confusing. The most interesting clouds that stayed with me after OOW14 where:
