Introduction Oracle SOA Suite 11g is a powerful and flexible platform for building composite applications that can connect many applications and "services". When the overall application performance appears slow, the bottleneck(s) could be anywhere in the system: the applications/services that SOA connects to, the infrastructure database, or the SOA server itself. How to quickly identify the bottleneck becomes crucial in tuning the overall SOA application performance. Main...

Introduction Let's say you experience some performance issues of your Oracle SOA 11G servers, and after some research you know that you need to tune your JVM heap size, and turn on some JVM debugging to monitor such as Garbage Collection behaviour. Main Article After some due diligence of reading WebLogic documents and Internet postings, you found the right flags to use, and the right values to set. It typically looks something like -Xmx4096M -Xms4096M -Xmn3072M...

Introduction B2B 11g has a number of parameters that can be tweaked to tune the engine for handling high volumes of messages. These parameters are also known as B2B server properties and managed via the EM console. Main Article This note highlights one aspect of the tuning exercise and describes the different threads, that can be configured to tune the performance of a B2B server. Symptoms The most common indicator of a B2B engine in need of a tuning is reflected in the...

Introduction In a separate posting, I mentioned you can configure multiple threads of inbound (polling) adapters of Oracle SOA. However, the ways to configure multiple threads vary between adapters and product versions, and the information scatter across multiple documentations. Hence it is worth to consolidate them here. Main Article This post is for Oracle SOA 10.1.3.x. I have another blog post for configuring adapter threads in Oracle SOA 11G. 1. JMS Adapter For BPEL: Set...

Introduction Until 11.1.1.3, BPEL audit trails are saved to the database in the same JTA transaction as the main transaction. This causes three main problems: Most common: Latency of saving audit trail to database is included as part of the overall latency of the main business transaction. Often seen: When the main transaction is rolled back for whatever reason, the audit trail did not get saved, because audit trails are saved in the main transaction as well. Thus no trace of...

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...
