SOA Made Simple | Introduction to SOA by Ronald van Luttikhuizen

December 20, 2013 Leave a comment

A lot of organizations are implementing, or want to implement, Service Oriented Architecture to support their goals. Service Oriented Architecture is a natural step in the evolution of Information Technology; we started out with big systems in universities and banks, and moved to desktop computers in the workplace and at home. We are now moving to solutions in the cloud, offering services to consumers and businesses alike, adding mobile computing to the mix. So what is a service? A service is something that has value. Service orientation is not a difficult concept to grasp, everyone knows services and uses them daily; think of a hotel that offers a shuttle service to the nearest airport. Or the hairdresser that cuts your hair. This presentation introduces SOA, using a practical and simple approach. It is done without overly complex abstractions, but with examples from different industries and hands-on experience. Get the presentation here.

Supporting multiple ebMS service versions in Oracle B2B by Ronald van Luttikhuizen

October 16, 2013 Leave a comment

In recent years I’ve been involved in different Oracle B2B implementations and troubleshooting projects based on ebMS and AS2 protocols. Not so long ago, I came across a project that needed to support multiple versions of an ebMS service. Versioning is quite trivial for SOAP and RESTful Web Services using e.g. different namespaces, version indicators in endpoint locations, and so on. However, it is a bit different for ebMS-based services implemented in a B2B gateway.

Case
ebMS is one of the protocols supported by the Dutch government standard DigiKoppeling for exchanging information between governments such as municipalities, provinces, and departments. In this particular case, the existing integration flow that needed to support a new version of an ebMS service is as follows: Read the full article here.

Article published | Fault Handling and Prevention (II) by Ronald van Luttikhuizen & Guido Schmutz

July 11, 2013 1 Comment

Oracle Technology Network (OTN) published the article Fault Handling and Prevention – Part 2 (Fault Handling and Prevention for Services in Oracle Service Bus) by Ronald van Luttikhuizen and Guido Schmutz.

Figure 1Part 1 of this article series on Fault Handling and Prevention discussed what fault handling is and why it is important. It also addressed the specific challenges in handling faults in a service-oriented landscape as compared to traditional systems. Part 1 concluded by presenting a sample scenario, an Order process implemented in a BPM and SOA environment, discussed potential pitfalls, and described generic fault prevention and recovery patterns.

Part 2 concentrates on concrete fault handling and prevention measures in the integration layer that are realized through Oracle Service Bus (OSB). The integration layer covers typical elements and integration functionality, such as Adapters for connectivity to back-end systems, Routing, Transformation, and Filtering.

SOA Made Simple by Lonneke Dikmans , Ronald van Luttikhuizen

May 31, 2013 Leave a comment

SOA Made SimpleSOA is an industry term which is often preached like a religion rather than taught like a technology, and over time, grasping the concept has become unnecessarily difficult.

Many companies proclaim that they do not know where to begin with SOA, while others have begun their SOA effort but have not reaped the benefits they were convinced it would bring.

“SOA Made Simple” explains what SOA is in simple terminology and by using real-life examples. Service-orientation is already a very natural way of thinking for business stakeholders that want to realize and sell services to potential clients, and this book helps you to realize that concept both in theory and practice. After reading “SOA Made Simple” you will have a clear understanding of what SOA is so you can implement and govern SOA in your own organization. If you are an architect who wants to be completely clear in your understanding of what SOA is, then this book is essential. In fact, anyone (designer, developer, administrator or team lead) who is implementing or about to implement an architecture in an IT environment should not miss out on “SOA Made Simple”.

If you published a book feel free to add it to our publications wiki!

From the Trenches | Patching OSB and SOA Suite to PS5 by Ronald van Luttikhuizen

April 18, 2013 Leave a comment

Recently I was involved in an Oracle Fusion Middleware upgrade from 11g PS2 to 11g PS5 with Jacco Landlust, Aiman Salama, and Jens Peters. The environment that was patched consists of the following domains:

  • Java domain running Java/JEE applications;
  • IDM domain running identity management components including OID;
  • SOA domain running Oracle Service Bus and Oracle SOA Suite. 

The domains consist of several Managed Servers in a single-node cluster configuration. OSB and SOA Suite both run in their own Managed Server.
There are plenty of excellent blogs that discuss the infrastructure and middleware side of such an upgrade. This blogs contains some things we encountered from the application side of things. More specific, the SOA composites and OSB projects.

Rebuild custom Java classes and JAR files in the SOA extension library
You can add custom Java classes and JAR files to SOA Suite that are used by your SOA composites. The SOA extension library for adding extension classes and JARs is available in the $ORACLE_HOME/soa/modules/oracle.soa.ext_11.1.1 directory. For example, an extension can be used to add a custom fault handler. Read the full article here.
