Monitoring large flow traces with Oracle SOA Suite by Martin Günther

End-to-end monitoring of BPEL process instances acro ss composite borders is a great feature of Oracle SOA/Business Process Management Suite 11g. It is shown in nearly every PreSales presentation and when you were used to know SOA Suite 10g or to work with other kinds of distributed, heterogenous systems it is a real improvement.

But when you implement large process chains you might realize that the newly won process transparency can raise new challenges. Imagine you have a root process which creates several instances of sub-processes. In such a case without doing any extra work you will get one flow trace for the process and all of its sub-process instances. For large process chains you need to consider the following facts:

  • Transparency: Although it shows an end-to-end view of the whole execution tree, trying to find a faulted sub-process might be a real challenge. It doesn’t matter if you start the search from the root process instance or from one of the sub-processes - the flow trace always displays all components of the execution context. When you click on a sub-process and you go back to the flow trace you might have to expand all child nodes again and again.
  • DataSetTooLargeException:  When your flow trace becomes longer and longer, you will observe, that there is a maximum size for the audit trail that can be displayed by Enterprise Manager. Usually it results in a java.lang.RuntimeException: oracle.soa.management.facade.DataSetTooLargeException: Requested audit trail size is larger than threshold … chars
    For large execution trees, sub-process instances might not be displayed or you might not be able to see things in detail.
  • Low Memory: It is not only the visible representation of your instance, which struggles. A huge audit trail implicitly means that your needed memory allocation for executing your process instance grows. It can grow to this extent that your process instance crashes because of running low in memory.

Sie erhalten einen komprimierten Überblick über die BPM-Philosophien von Oracle Lager und vielen bedeutender Experten aus diesem Umfeld. Highlights der Konferenz sind beispielsweise die Keynote von Prof. Frank Leymann zur allgegenwärtigen Diskussion rund um den neuen BPMN-Standard und natürlich auch Max J. Pucher, dem Vordenker des Adaptiven Case Managements (ACM), welches endlich die dynamischen Aspekte in der BPM-Welt adressiert, die so schwer in starre Prozesse zu fassen sind.

Am ersten Tag können Sie sich in jeweils drei parallelen Tracks über neue Trends, Sichtweisen und Entwicklungen informieren. Am zweiten Tag können Sie wichtige Schwerpunktthemen in vier Halbtagesworkshops und einem ganztägigen Workshop intensiv vertiefen. Auch das Speaker Panel am Mittwochabend sollten Sie nicht verpassen.

Swarm Computing – Next Generation Clouds and the Role of SOA – my presentation from the SOA & Cloud Symposium

If you had not to chance to attend the SOA & Cloud Symposium you can now watch the key presentations at InfoQ

My presentation at the SOA & Cloud Symposium website and as a video at the InfoQ website. Joe McKendrick with a nice summery and feedback. If you like to present at future events check out our SOA call for papers wiki

Presentation abstract

We either use public clouds, for example Amazon EC2, most times for training or development purposes. These environments are only used for a limited time frame. The second cloud models are private clouds, used by corporations in their own datacenters to increase the utilization of their servers across multiple applications.

Today, we use either private or public clouds for certain use cases. To enable a wider adoption of business solutions, hybrid clouds will be the future model. Key will be integration, as well on the data level, the service level and the process level. Processes might start in a private cloud continue in a public cloud and will be completed in a private cloud.

For example, a rental car company (RYLC) starts a promotion for convertibles on their SaaS solution, in their legacy system new promotion and price is added to the financial system. A customer rents the promotional convertible in the public cloud online store. The order is processes and billed from the private cloud system. In this case SOA will be the key enabler for:

-SOA Integration: Integration on all levels will be key, to integrate data, services and processes between legacy systems, private cloud systems and public cloud systems to hybrid systems.
-BPMN process change: Processes based on BPMN 2.0 across hybrid clouds can be adopted by the business owner to respond on flexible business requirements.
-Middleware and SOA Governance enable atomic, loosely coupled participants.

With the RYLC example we will demonstrate many examples in a show case using various technologies including open source. Lastly we will discuss, swarm computing, a future cloud solutions. Today cloud systems are often limited to a small number of use cases e.g. test system or training systems. For a wider business adoption more intelligent systems are required. Meta data and ontology’s will be the enabler for intelligent systems which interconnect with each other.
