Introduction In SOA 10G, it is a good practice to have BPEL and ESB co-located at the same JVM. Doing so not only improves performance but also allows JTA global transaction propagation between the two. However, these advantages will not be fully materialized, or even will totally disappear, if wrong protocols were chosen when these two components call each other. Main Article 1. BPEL calling ESB When developers write BPEL processes that call ESB, many don't think about the...

Introduction A customer recently used strace on a WebLogic server that was having some trouble. The first thing that jumped out at them was hundreds of SIGSEGV, also known as Segmentation Fault, events showed up in the output. They opened a support incident and asked for more information on what might be causing all of those segmentation faults. Main Article Most people that have used Unix for any amount of time are familiar with occasionally seeing "Segmentation Fault (core...

Note: The information in this article while accurate is dated. For the latest information on BPM correlation please refer to the 12c BPM Developer's Guide document. Introduction Prior to 11.1.1.5FP, Oracle BPM Suite supported only automatic correlation via WS-Addressing. If message based correlation was needed, the common approach was to delegate the correlation tasks to a BPEL process front ending BPM Suite. Starting in Oracle BPM Suite 11g R1 PS4FP, out of the box support...

Introduction This post builds on the earlier posts in this series which showed an approach to getting started with continuous integration for Oracle SOA and BPM. In this post, we will look at how to add SCA Tests to our continuous integration environment – executing them as part of the build, and reporting on them in the continuous integration server. Main Article Let’s start by building a very simple composite with a test, then we will get that working in our continuous...

Introduction WebLogic Server includes a feature called the ‘JMS Wrapper’ that you can take advantage of to dramatically improve the performance of JMS applications running on WebLogic Server. Note that this is not for remote JMS clients, this is for JMS programs running on WebLogic Server, like Servlets or EJBs. Main Article In this post, I will demonstrate how to use the JMS Wrapper to improve the performance of a Servlet based JMS application. On my Mac Book Pro, I was...

Introduction XQuery transformations are often used in pipelines in Oracle Service Bus to perform data transformation. Performance of XQuery transformations is a key area to focus on when performance tuning an Oracle Service Bus environment. Main Article During performance testing of your project you should use the activity timing metrics to identify any XQuery performance issues and optimize those queries for better performance. The recommended approach is to measure the...

Introduction Occasionally I need to change the port that my WebLogic AdminServer is listening on, without actually starting up the server. Usually this is because I have just created a new domain, and I forgot to change the port in the Domain Configuration Wizard (oops!), and now I can’t start the server up because there is already another one using that port. One way to get around this is to use the WebLogic Scripting Tool (WLST) to change the listening port. Main Article...
