Our new book “Design Principles for Process-driven Architectures Using Oracle BPM and SOA Suite 12c” got published

DesignPrinciplesBPMandSOA

In the past year I have contributed to a new Packt book titled “Design Principles for Process-driven Architectures Using Oracle BPM and SOA Suite 12c”. I’m very happy that we have managed to publish it this June.

This book is a design handbook and provides skills to successfully design, implement, and optimize business processes on top of SOA. Starting with business process modeling, it shows design principles to architect sound process architectures. It presents best practices for modeling business processes using BPMN, together with design principles for services and composite applications. It provides detailed coverage of how to prepare business processes for execution. An in-depth explanation of human interactions is given and also principles and best practices for using rules.

Moving on, Adaptive Case Management principles are explained, along with the reach of business processes to mobile devices and ensuring multichannel interactions. Business activity monitoring, event-driven architectures, complex event processing in relation to business processes, and enabling integration with events and IoT devices are explained. The design principles and best practices are demonstrated in a practical way on a rental car use case.

You will learn

  • Design principles to model business processes and business architectures
  • Best practices to produce executable business processes in BPMN
  • Principles when designing reusable services and composite applications
  • Advanced approaches to human interactions in business processes, including patterns and Adaptive Case Management
  • Business rules management and principles for rule design and implementation, including using rules in BPMN and BPEL processes
  • Prepare process applications for mobile and multichannel/omnichannel
  • Explore the best practices and principles of Business Activity Monitoring to define and monitor Key Performance Indicators
  • Extend the processes to Internet of Things devices and processing complex events

Enjoy the reading! We hope you like it!

I’m speaking at DOAG IMC Summit, 6th June 2013 in Mainz, Germany

In June I will be speaking for the German Oracle User Group (DOAG) at the Infrastructure and Middleware Community Summit in Mainz. This is all about Oracle Infrastructure and Middleware topics and has great speaker lineup for the german-speaking Oracle community.  The summit consists of the three tracks “Infrastructure”, “Middleware” and “on top of Middleware”.

My speech will be in the “on top of Middleware” track and it will be about “Where and when to use the Oracle Service Bus (OSB)”. Here is the abstract to my talk in german:

Der Oracle Service Bus (OSB) ist Bestandteil der SOA Suite 11g und steht im Zentrum moderner Prozess-. und Integrationslösungen. Die leichtgewichtige, zustandslose und hoch-performante Architketur des OSB macht ihn zu einem hervorragenden Werkzeug für die Transformation und das Weiterleiten (routing) von Nachrichten. Diese Präsentation erklärt wo und wann der Einsatz des Oracle Service Bus Sinn macht, zeigt dabei aber auch auf, wo die Limitationen des OSB sind. Wo sinnvoll wird auf die weiteren Komponenten der Oracle SOA Suite bzw. der Oracle Fusion Middleware hingewiesen. Anhand von bekannten Design Patterns wird gezeigt, wie diese mit dem Oracle Service Bus effizient umgesetzt werden können. Themen des Vortrages sind: Load-Balancing, Service-Throttling, Transaktionen, Adapter und Transformation über XQuery. 

Looking forward to meeting you there! 

My presentations at Oracle Open World 2012

Oracle Open world 2012 is already past and I’m back in Europe. Here is just a quick wrap up of my involvements at OOW 2012. 

Oracle Fusion Middleware Live Application Development (UGF10464)

For the fourth time, the Live FMW Application Development show has been held. This time at Oracle Open World 2012,  during the ADF EMG community event on Sunday organised by Chris Muir. I joined the team for the first time, as due to my injury in last december, I was not able to be part at UKOUG 2011. For three hours, we demonstrated the audience (around 100 participants) how an application can be created across the tiers – UI (ADF), Process (BPM), Service Integration (SOA Suite) and the Database. Because we had only one beamer available, we first presented for each tier how the development works and then in the second phase, we presented how some changes/addons can be applied to the 1st iteration. I was part of the Service Integration team, together with Ronald.

The slides of the show are available on slideshare. Only a few, the real value was of course in the live demo!

It was fun to be part of the team, hope we can repeat it soon somewhere else! Thanks to Lucas, Chris and Duncan for organising the show!

There were also some discussion about further using the material, such as some videos on youtube, writing an article series….

Effective Fault handling in SOA Suite 11g (CON4832)

In this co-presentation with Ronald van Luttikhuizen we presented how the built-in functionality of Oracle SOA Suite and Oracle Service Bus can help to implement fault handling and fault prevention. We used an example scenario, which is complex enough to show some real live problems in a service-oriented solution with a mix of services, technologies and platforms. 

Use case with possible fault szenarios

The session was pretty well attended, and with an extended Q&A sessions at the end. We got quite a lot of interesting questions and I even had to leave earlier, as I had my next presentation just after this one.  

The slides are available on slideshare. We are currently writing a series of articles which will dive deeper into the subjects of error handling and error prevention and show how the SOA Suite 11g platform can help. 

Five Cool use cases for the Spring component of Oracle SOA Suite (CON6210)

My last presentation at Open World 2012 was about the Spring component of the Oracle SOA Suite.

The Spring component makes it possible to embed Java code as a Service Component Architecture (SCA) first-class citizen through the Spring component implementation type. Thereby the coarse-grained components of Oracle SOA Suite (such as BPEL, Mediator) can be extended by much-finer-grained Spring beans wrapped inside the Spring component. The goal of the session was to show how and why you want to use the Spring component and to hopefully inspire attendees to use it for their own projects.

There is of course a question what “cool” means. Cool and practice-related doesn’t always match and of course I wanted to also show some use cases which are actually useful at daily work. 

It took me quite some time to put the use cases together and to make them working. Especially because I have not previously worked with some libraries/frameworks i have used. At the end I presented the following use cases:

  • Advanced Configuration through JMX
  • Dynamic Routing in SOA Suite (i.e. publish/subscribe)
  • Integration of MongoDB NoSQL database
  • Integration of Twitter to send update messages
  • Integration of Twitter to receive mentioned messages

As you can see on slide 40, I had some other ideas, but just not enough time to do them as well. Maybe I will do it for a session on another conference. 

The slides are available on slideshare. I have also planed to write some further blog articles, one for each use case I have presented and to show step by step how the use case can be implemented.

 

It was a lot of work to prepare the session, but enjoyed it! 

The making of the Oracle Service Bus 11g Development Cookbook

4446OS_Oracle Service Bus 11g Developement Cookbook_FrontcoverAlmost a year ago I started to think about writing a cookbook for the Oracle Service Bus (OSB). I first discussed it with Mischa Kölliker, a colleague at Trivadis and he was happy to join the team. Next I have used the Oracle SOA and E2.0 Partner Community Forum in March 2011 to talk to Edwin Biemond and Eric Elzinga, two well-known OSB experts and Oracle ACE colleagues. Gladly they were as enthusiastic as me about putting together a book with lot’s of recipes of how to use the Oracle Service Bus in practice. They also introduced me to Jan van Zoggel, who joined the team as well. So the setup of the team of authors was complete: The Netherland – Switzerland 3:2 (could have been the final result of a football game).

I have then started to talk to Packt Publishing, the publisher of the book, about my idea and the team I have put together. At the beginning of May 2011 the outline for the book was setup and at the end of May 2011 we have signed the contract with the publisher.

This was the start of 6 very busy months for me, writing and internally reviewing the 80+ recipes inside the 12 chapters of the book!

At the beginning our aim was to include recipes for all roles involved in the development of an OSB solution. But in August 2011, after writing the first few chapters, we could see that it would not be possible to fit all of that into the 500+ pages we agreed with Packt, which I think is a reasonable size for such a cookbook. That’s why we decided to change the focus to an OSB Development Cookbook, “only” including recipes targeting the development on the Oracle Service Bus. That’s why topics such as Monitoring, Management, Deployment are not covered in that book.

We finished the draft version of the book at the end of November.

From middle of December, I have worked on the feedback we got from the reviewers and finish everything by the end of the year. Thanks to Matthias, Jelle, Matt and Peter for your valuable input and comments, we really appreciate your help!

Unfortunately I broke my leg at the beginning of December playing ice hockey. But that was positive for the book, as I had a lot of time to really focus on the last part of the project and to make sure to reach the deadline we got from the publisher.

In January 2012 the final changes to the book have been made and then the production started with the result now being publicly available!

The book now contains a bit more than 80 practical recipes to develop solutions on the Oracle Service Bus 11g. The are organized into the following 12 chapters (digit behind the title is the number of recipes contained in the chapter):

  1. Creating a basic OSB service (13)
  2. Working efficiently with OSB artifacts in Eclipse OEPE (7)
  3. Messaging with JMS transport (9)
  4. Using EJB and JEJB transport (5)
  5. Using HTTP transport (5)
  6. Using File and Mail transports (5)
  7. Using JCA adapter to communicate to the database (6)
  8. Using SOA Direct transport to communicate with SOA Suite (4)
  9. Communication, Flow Control and Message Processing (10)
  10. Reliable communication with OSB (5)
  11. Handling Message-Level Security requirements (9)
  12. Handling Transport-Level Security requirements (4)

Throughout the book, we have consistently used diagrams, such as the one below, to clearly show the setup of a given recipe. The following image is showing a proxy service using the AQ JCA adapter to consume from a queue (EVENT_QUEUE) inside an Oracle database.

I got the printed version of the book a few days ago and I really like the result!

You can find the first two reviews of the book here:

Thanks a lot to the team at Packt Publishing for all their hard work and support. It has been a long journey, but I’m very happy with what we have achieved!

You can get it as an EBook and/or printed book directly from Packt Publishing or Amazon. Hope you like it! Enjoy your reading and cooking!

Was writing the Oracle Service Bus Development Cookbook….

The long silence on my blog in the past 10 months has a one reason: I was really busy writing the upcoming Oracle Service Bus Development Cookbook, published by Packt Publishing.

I’m co-writing this book together with the following friends from the European SOA community:

The book contains more than 80 practical recipes to develop service- and message-oriented solutions on the Oracle Service Bus 11g.

This cookbook is full of immediately usable recipes showing how to efficiently develop on the Oracle Service Bus. In addition to its cookbook style, which ensures the solutions are presented in a clear step-by-step manner, the explanations go into great detail, which makes it good learning material for everyone who has experience with the OSB and wants to improve. Most of the recipes are designed in such a way that each recipe is presented as a separate, standalone entity and reading of prior recipes is not required. The finished solution of each recipe is also made available electronically.

The 80+ recipes are organized into the following chapters (the digit behind the title showing the number of recipes in that chapter):

  1. Creating a basic OSB service (13)
  2. Working efficiently with OSB artifacts in Eclipse OEPE (7)
  3. Messaging with JMS transport (9)
  4. Using EJB and JEJB transport (5)
  5. Using HTTP transport (5)
  6. Using File and Mail transports (5)
  7. Using JCA adapter to communicate to the database (6)
  8. Using SOA Direct transport to communicate with SOA Suite (4)
  9. Communication, Flow Control and Message Processing (10)
  10. Reliable communication with OSB (5)
  11. Handling Message-Level Security requirements (9)
  12. Handling Transport-Level Security requirements (4)

Today I have finished the review phase of all the chapters, so that production of the book can start beginning of 2012. I expect that the print book will be available in February 2012.

But the book is already available as a RAW book. A RAW (Read as we Write) book is an eBook available for immediate download and containing all the material written for the book so far. You can get it from here.

Looking forward for the print book, we hope you will like it!

WebLogic Server, JDev, SOA, BPM, OSB and CEP 11.1.1.4 (PS3) available!
