Industry Data Models, Processes and Architectures

Recently while listening to OTN ArchBeat podcasts, a panel discussion on Reference Architectures (part 2 and part 3) I was thinking back to some pieces I wrote on industry data models and processes that I didn’t share with you yet. There a some similar argument to using these and reference architectures.

The value of reference models whether it contains data models, standardized messages, processes of a reference architecture, is or should be in a faster time to market and better quality of the solution.

Handle with care

What makes it hard to achieve this value, is the fact that these models contain always far more than is needed. That can be considered a waste. Even the parts that are not used still require attention while implementing and maintaining. This incurs work to understand the complex model, hide the details you don’t need, and customize and extend the parts you need.

Implementing a reference model requires spending time to determine how and to what extend this model meets the needs of your business? That is typically something you have to discover for yourself. It is where the majority of the time is spend! If you don’t go through the effort of understanding your business requirements, you are missing understanding of how the business can and should use the model. That makes it very hard to determine the value of the end solution to the business.

When using a reference models you should be aware that your business is not average. In some shape or form it delivers value to your customers in away a reference model doesn’t provide. Reference models should be used with care your business deserves.

Lean Integration Presentation

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.

Presenting at Seminar “Lean & Agile IT: beter resultaat, betrokkenheid en IT volwassenheid” (Dutch)

Martin van Borselaer asked me to present at a seminar he is organizing on Lean and Agile IT. I’ll be presenting on Lean Integration and will probably also offer a peek into the Integration Factory.

This seminar will take place on Thursday September the 15th at our Whitehorses head office in Nieuwegein, the Netherlands. It’s in Dutch and aimed at our customers or potential customers. More information on the seminar program.

We’re looking forward to share our ideas with you. Hope to see you there!

ESB: No WebService Provider is registered at this URL

When you are using Oracle ESB 10g and encounter the message No WebService Provider is registered at this URL when testing a web service from the ESB Console try the following:

Oracle Enterprise Manager OC4J_SOA


Verify the ESB web service providers are generated correctly in ESB runtime (known as the esb-rt):

  • Login into Enterprise Manager
  • Go to the Application Server Control
  • Click OC4J_SOA oc4j instance
  • Click Web Services tab
  • Verify the deployed web services are listed here, and test that services.

In case there are no web service from the ESB runtime (esb-rt) the service providers were not generated correctly, restart ESB-RT:

  • Click OC4J_SOA oc4j instance
  • Click the Applications tab
  • Expand Middleware Services, ESB and esb-dt
  • Check the esb-rt and click the restart button

Now check the j2ee/_instance_name_/log/*/oc4j/log.xml to see if the ESB application has started correctly. Verify that ESB-RT application is initialized correctly by searching for ‘ESB bootstrap: Runtime initialized‘ message in the log file. If you also restarted the ESB-DT, verify that ESB DT application is initialized correctly by searching for ‘ESB bootstrap: Repository initialized‘ message in the log file. And finally check that the ESB web service providers were generated correct (see above).

Some useful AIA 11g links

For my own reference some useful AIA 11g Foundation Pack references:


The AIA 11g Foundation Pack documentation:

InfoQ videos: Using a Service Bus to Connect the Supply Chain

The session I presented at the SOA Symposium 2010 is now available online via InfoQ. You can find it as a Service Bus case study. It is introduced as:

a case study of using a service bus in a supply channel connecting a wholesale supplier with hundreds of retailers, the overall context and challenges faced – including the integration of POS software coming from different software providers-, the solution chosen and its implementation, how it worked out and the lessons learned along the way.

Watch the video, download the mp3 or sheets.

SOA Symposium 2010 videos available via InfoQ

This year, in partnership with InfoQ.com (the largest community site for technical architects), 1/4th of the SOA Symposium sessions was filmed and will be published on InfoQ. From early November InfoQ has started publishing these videos. At the time of writing the following videos are available:

Cloudy SOA

This session on Cloudy SOA by Mark Little covers:

an introduction to cloud computing pointing to the fact that the middleware needs of the cloud are similar to SOA’s, showing some of the benefits of running SOA along with the cloud, asking if cloud computing and SOA should evolve together and giving some future directions to consider.

BPM Top Seven Architectural Topics in 2010

Hanjo Normann’s session presenting the BPM Top Seven Architectural Topics in 2010 covers:

how to design a BPM/SOA solution including: modeling human interaction, improving BPM models, orchestrating composed services, central task management, new approaches for business-IT alignment, solutions for non-deterministic processes, and choreography.

Resurrecting SOA

Anne Thomas Manes in her Resurrecting SOA session goes into details on why she:

believes organizations need SOA more than before, but using a redefined SOA based on the SOA Manifesto, focusing on models, methodologies and patterns, not on technology, intended to produce the desired business and technical goals.

Sharing artifacts using the MDS Repository

Both during development and maintenance of code, deployment strategies relying on copying of artifacts will fail, or at least complicate the task at hand and frustrate reuse. SOA Suite offers a centralized storage for artifacts (like WSDL, XSD, and XSL files) that can be accessed both at design time and at run-time. It is called the MDS Repository, and comes with Metadata Services on top of it. It is part of the SOA Suite and doesn’t require additional installation. This blogpost will show you how to upload an artifact to the central MDS Repository, and how to use the uploaded artifact in your source code.

Locate and copy the WSDL

Locate the WSDL file in your project on the local file system, for example: C:\JDeveloper\mywork\AIApocBOUW\CreateInventoryTransactionRIBRMSProvABCSImpl.wsdl. In which a convention like C:\JDeveloper\mywork\__Workspace__\__project__ is used. You can also determine this path in JDeveloper by selecting the WSDL file and use CRTL-SHIFT-C (or by selecting contextmenu – Copy Path).

Use an FTP tool to move the file to the server running the SOA Suite. The path to use on the server depends on the application, version and component type. Typically in AIA there is a structure like $AIA_HOME/AIAMetaData/AIAComponents/ApplicationConnectorServiceLibrary/__Application__/__version__/__componentType__ . Where in AIA component types are ABCS Provider, ABCS Requestor, EBS, et cetera. In other environments you can create your own structure. Since you no longer need a local copy of the WSDL, remove it from your local file system.

Load the WSDL in the MDS Repository

To load the WSDL and other artifacts to the MDS repository there is an ANT script available on the server. To use ANT, make sure the needed environment settings are made correctly. When you installed AIA there is a Shell script available the will source both AIA and ANT environments: aiaenv.sh. This script can be found in ...../weblogic/aia30/aia_instances/aia30poc/bin. It can be convenient to copy this to your home directory.

  • Source AIA and ANT environment: source ./aiaenv.sh.
  • Alter the UpdateMetaDataDP.xml configuration file. It can be found in ...../weblogic/aia30/aia_instances/aia30poc/config.

In case your vi isn’t up to par use a tool like WinSCP and choose Edit in the context menu:

In the UpdateMetaDataDP.xml file alter the file set. In the example on which the screenshot is based
is added.

And now you are ready to run ANT using the actual loading script:
ant –f /fs01/app/oracle/esbtst01/weblogic/aia30/Infrastructure/Install/scripts/UpdateMetaData.xml

Check the output of the ANT script:

  • check that the correct number of files has been copied.
  • the server gave a HTTP response 200.
  • The deployment of the composite was successful.

Another check to verify a correct load into the MDS Repository is to use the MDS Browser in JDeveloper to find the file you just uploaded. A refresh of the view could be needed to include the latest changes and additions.

Using the WSDL in the MDS Repository in your source code

The last step is to reference to the WSDL in the MDS Repository, since the file has been removed from the local file system. Double click the Exposed Service to open the wizard:

Choose Existing WSDL to select the WSDL from the MDS Repository:

Check the change using the source view. In the import of the WSDL in the composite.xml there should now be an URL referring to oramds:, like in the example below:

<import namespace="http://xmlns.oracle.com/ABCSImpl/LOCUS/Core/CreateStockChangeLOCUSReqABCSImpl/V1"
