Docker – Take Two – Starting From Windows with Linux VM as Docker Host by Lucas Jellema

clip_image002My first attempt with Docker was from my Windows host machine using boot2docker, as described in this article: https://technology.amis.nl/2015/03/15/my-first-steps-with-docker-starting-from-windows-as-the-host/. Boot2docker is a great tool for being able to work with Docker on a Windows machine. However, I ran into limitations – such as not being able to create containers with the GUI applications running in them. Besides, Linux seems to be – for now at least – the more natural environment for Docker. So decided to create a Linux VM – actually a Virtual Box VM – that would serve as my Docker host.

In this article I will walk through the steps I went through in order to get this Linux VM running on my Windows host and subsequently turn that VM into the Docker Server in which one or more containers will be running – eventually to serve as demo and training environments, for example with Oracle Databases and Middleware. After all, Mark Nelson showed the way in this wonderful article: https://redstack.wordpress.com/2014/11/14/gettingn-to-know-docker-a-better-way-to-do-virtualization/.

I decided to closely follow Mark’s lead in his choice of Linux VM: Ubunty 14.04.1, to be created using Vagrant (about which I have blogged before – for example https://technology.amis.nl/2014/06/26/provisioning-an-oracle-11g-database-virtualbox-vm-with-vagrant-and-puppet-for-dummies/ ).

Stage One – Create Ubuntu VM using Vagrant

I have both Vagrant and Virtual Box set up on my laptop. From that starting point, I open a command line window and create directory into which to create the Vagrant configuration for the VM. Read the complete article here.

ADF12c-WebSockets-SlidePresenterDemo by Lucas Jellema

clip_image002

WebLogic 12c (12.1.2) has support for WebSockets. ADF 12c runs on WebLogic 12c. Therefore, we should be able to leverage that WebSockets support in an ADF application. And indeed we can, as this article describes. It will explain the creation of a simple application – the SlidePresenter – that allows users to select an image from a carousel. As soon as they make the selection, all currently connected clients are synchronized, showing the same slide: Read the complete article here.

JavaOne 2014: Roadmaps for the near future of Java By Lucas Jellema

clip_image002JavaOne 2014 is first of all a community gathering – with over 500 sessions that discuss Java related topics in tantalizing details. A meeting of minds, of kindred spirits etc. It is also the place where the roadmap for the near future of the various constituents of the Java platform is unfolded. The slides in this article are taken from the Java Keynote on Sunday 28th September 2014.

ADF 12.1.3 – Highlights in Data Visualization (DVT) by Lucas Jellema

One of my favorite areas in ADF Faces always has been the Data Visualization [Tags] aka DVTs. I feel that we make far too little use of the power of visualization to present information and even call to action to our end user instead of raw data – as we frequently do today. The table component is probably the most widely used component in all of ADF Faces – even though it is most often used to just present raw data.

The DVT components in stark contrast are overlooked or regarded as just a nice to have. I hope to bring about a change – making designers, developers and end users themselves more aware of the value of visualizations. Oracle Fusion Applications and especially the simplified UI provides an excellent example of how visualizations can be used to help end users focus on what is relevant: aggregate, exception, trend, comparison etc.
ADF 12.1.3, freshly released, brings a next wave of enrichment of the DVT components. Allowing developers to create even more useful and appealing visualizations. In this article, I want to describe and show some of these new features.

Client Side Charting Solutions
The DVT team is leveraging an increasing number of HTML 5 features. After the introduction of HTML (5) as rendering option next to Flash, we now see a rapid acceleration of the use of HTML 5 facilities. One area where this happens is with the client side charting solutions. This involves a number of chart types (Bubble, Pie, Bar, Horizontal Bar, Line, Pie, Area, Scatter and more) for which client side operations such as hide/show of series, rescale and zoom/scroll + navigate in overview window are supported. Because these operations are handled entirely on the client side, the interaction is much smoother and faster than with the server driven charts.
An example is shown below. Both pictures are based on the same data. On the left, the overview window is focused on a six month period. On the right, the time selection has been enlarged to contain over three years. Resizing and refocusing the time window is a smooth , client side operation that constantly synchronizes the line chart shown on top. Read the complete article here.

ADF in Action – slides and demonstration from OUGF 2014 by Lucas Jellema

During this week’s OUGF 2014 Harmony conference in Haltia, Finland I presented on Oracle’s premier application development framework: ADF.
ADF is the strategic application development framework for Oracle, a core element in Fusion Middleware. ADF can be used to create large scale, enterprise applications. It can be used to create entirely license free applications. It can be used to create cloud applications and also applications that can be used from all kinds of mobile devices.

This presentation provides an overview of ADF: what it consists of, what it can be used for, what it is better not used for, what does it take to (learn how to) develop ADF applications is an important question that is addressed. The presentation features several demonstrations of the both the first HelloEmployees application as well as a number of advanced ADF mechanisms.

If you have not recently – or ever at all – seen ADF in action, and application development does take place in your organization, this session is a valuable quick introduction and overview. Get the presentations here.

AMIS Oracle Enterprise Mobility conference review

This article will provide a live account of the three day Enterprise Mobility conference, hosted by AMIS in Nieuwegein, The Netherlands. Oracle ADF Product Managers Frank Nimphius and Chris Muir are the keynote speakers. They are joined by Willem de Pater, Steven Davelaar and Lancy Silveira from Oracle and Luc Bors, Frank Houweling, Paul Swiggers, Aino Andriessen and Lucas Jellema from AMIS. The presentations and demonstration during this conference cover the next step for most enterprises (with ADF or without): introducing enterprise mobility. Many of the themes currently or shortly relevant to any organization will take center stage: multi device UI, mobility, security, agile & automated software engineering, performance & scalability, user experience, web & mobile oriented architecture and cloud. It will discuss and demonstrate Oracle’s vision and the upcoming generation of products.
The audience is composed of about 40 experienced ADF application architects and developers that not just sit back and relax, but share their experiences and ask the tough questions. How well does ADF fit in the mobile world? What is the role of ADF in a future that consists of HTML 5 and mobile? What is the long term evolution of ADF – and the use Oracle itself makes of the framework?
Note: the Twitter hash tag for this event is #amis_m2e (follow us on Twitter: live twitter-feed)
Friday 23rd May
16:30 Aino is still going strong. He is advocating the use of automation in our build, test and deployment processes. To use Maven (with 12c) and Ant (for 11g). To use Hudson or Jenkins to organize frequent, automated build in our development and testing environments and to perhaps look a little bit further (XL Deploy, Bamboo, Go) when it comes to deployment strategies for Acceptance Testing and Production environments.

Exalogic the WebLogic machine fully supports Oracle VM, Coherence and Virtual Assembly Builder:

clip_image007

A new Exalogic feature is Exabus – High Speed Network Virtualization. On the WebLogic side Oracle Traffic Director is my personal highlight. Traffic Director is a Load balancer or Local traffic manager on the application network layer.

Oracle Traffic Director facts:

  • Supports support SSL encryption.
  • 40GBps InfiniBand connections instead of the 1GBps
  • Virtual appliance (VA) running on Oracle VM Server
  • SSL-offloading, caching and redirecting
  • Tight integration with OHS and Apache
