BPEL 2.0 introduced the forEach activity – similar to for [-loop] found in many programming languages. Oracle SOA Suite 11g adopted BPEL 2.0, first in run time (PS2) and later in Design Time (JDeveloper) as well (PS3 an beyond). For BPEL processes created using BPEL 2.0, forEach is a looping […]

Keeping your process clean: Hiding technology complexity behind a service
This blog will explain how you could abstract technology behind a service so your main process will be kept clean of all kind of technology pollution like exception handling, technology adapters and correlation.

Batch Aggregation of files in BPEL process instances based on correlation
Remco is an interesting guy with unexpected ideas springing from a creative brain. He can make life interesting, challenging and puzzling. This time he had another interesting challenge – not all that weird to be honest. The challenge in short was: Our invoicing system produces files that contain one or […]
Migrating your BPEL 1.1 process to BPEL 2.0 – SOA Suite 11gR1PS2 to PS3
In my current project we just started creating BPEL 1.1 processes. Then SOA Suite 11gR1PS3 came along and gave use BPEL 2.0. As we are just in the early stages of development we decided to have a look at the impact of upgrading our already build BPEL 1.1 processes to […]
SOA Suite 11gR1 PS3 – Some new BPEL features
The Patch Set 3 for SOA Suite 11g R1 that was released last weekend brings bug fixes, stabilization, further integration between components and a bunch of new features. Most of them not spectacular, but quite useful all the same. More to please users of the product than perhaps potential buyers… […]
Embedded Java in a 11g BPEL process
In an earlier blog my colleague Peter Ebell (link) explained how you can create an extension of collaxa.cube.engine.ext.BPELXExecLet to do your coding in a regular Java environment so you have code completion and validation. In 11g no improvements have been implemented and the Java embedded activity is still a pretty dumb […]

Getting Started With Oracle SOA Suite 11g R1: A Hands-On Tutorial Authors: Demed L’Her, Heidi Buelow, Jayaram Kasi, Manas Deb, Prasen Palvankar (aka Oracle Product Management for SOA Suite) A hands-on tutorial is what the cover of the book promises, and that is exactly what you get. A quick, very […]
OOW 2009: Introducing SOA and Oracle SOA Suite 11g for Database Professionals
The Oracle Open World 2009 conference is almost underway. On Monday 12th October I will do two presentations, and I am done preparing the first one of them (the one that has actually sold one – probably scheduled in a small room).This presentation is one in which I introduce […]
SOA Suite 11g – Composite instance as WebService Result Cache using BPEL Correlation
This article describes an architectural pattern, implemented in the Oracle SOA Suite 11g, that is somewhat similar to the Oracle Database 11g Function Result Cache. It introduces a SOA Composite Application in the role of Result Cache. In its most simple form, the result cache is initialized – loaded with values -, […]
Chatting from SOA Suite 11g – how BPEL processes can use the XMPP protocol to notify the world
Various scenarios may require sending email messages or other types of notifications to users as part of the process flow. For example, certain types of exceptions that cannot be handled automatically may require manual intervention. For example, a BPEL process can use the notification service to alert users by voice, […]
Advanced Concurrency control in BPEL Flow – controlling the execution of parallel branches
In a previous article I discussed the parallel execution of activities in BPEL, more specifically in Oracle BPEL PM 11g (TP4). This article concluded that true parallellism hardly exists. The branches within a Flow get their chance in turns to execute their next step. Not until an activity is complete […]
Investigation into the true parallellism of the Oracle BPEL PM Flow activity in 11g (Technical Preview 4) – on flow, sequence, wait and (a)synchronous calls
The Flow activity is used to configure parallel activity in BPEL processes. In theory, activities contained in two or more branches (sequence containers) inside a Flow activity are executed in parallel. However, some sections in the BPEL PM documentation raise some doubt: "By default, Oracle BPEL Process Manager executes in […]
Debug Logging in BPEL using Sensors – Part 1
When developing and/or debugging BPEL processes, the Oracle BPEL Console is your best friend. Every change to every variable, every activity that was executed, everything is right there for you to inspect, whether the instance is still in-flight or already completed. But although this sounds like the ultimate debugging tool, […]
