Performance Study – REST vs SOAP for Mobile Applications by Steven Davelaar

clip_image002Introduction

To build functional and performant mobile apps, the back-end data services need to be optimized for mobile consumption. RESTful web services using JSON as payload format are widely considered as the best architectural choice for integration between mobile apps and back-end systems. Nevertheless, we have seen many customers of Oracle’s Mobile Application Framework (MAF) consuming SOAP web services in their mobile apps. One reason this is happening might be the nice declarative support in MAF/JDeveloper where you can easily create a SOAP-based data control through a wizard and build your pages using drag and drop. However, this wizard is only intended for really simple SOAP services. It cannot handle all XSD types, nor can it handle more complex, nested payloads. One way to work around these limitations is to process the SOAP payload programmatically in Java, but this is not a trivial task to do. While most of the issues around consuming more complex web services can ultimately be solved, this article explains why you should really abandon SOAP and go for REST-JSON services for one simple reason: performance. The differences in performance are staggering and get worse as the mobile device gets older.

Main Article

This articles discusses the results of a test conducted by Oracle’s A-Team to compare the performance of REST-JSON, REST-XML and SOAP service calls in MAF. We will first discuss the test set-up, then discuss the test results and we will end with a discussion of the options you have if you are currently consuming SOAP web services in your MAF application.

Test Set-Up

We have created an ADF Business Components (ADF BC) application that uses the HR schema to return a list of departments, including a nested list of employees for each department. So, the payload returned consists of 27 departments with 107 nested employee records.Each department row has 4 attributes, each employee row has 11 attributes.
In JSON format this payload is 26.2 KB, in XML format the payload is 77.3 KB in size (whitespace and carriage returns have been removed). Read the complete article here.

BPEL and BPM's performance monitoring using DMS by Sylvain Grosjean

What is DMS ?
The Dynamic Monitoring Service (DMS) API allows you to add performance instrumentation to Weblogic Server and Fusion Middleware (BPM, BPEL, Rules, OSB, Human Tasks, B2B...). During runtime DMS collects performance information, called DMS metrics that developers, system administrators, and support analysts use to help analyse system performance or monitor system status.
These performance metrics captured by DMS are available via the Spy Servlet and via MBeans.

BPEL/BPM Threading Model's Review :

Dispatcher system Threads : allocated to process system dispatcher messages.
Dispatcher invoke Threads :
(synchronous invoke) allocated to process synchonous requests, For each payload received, the thread will instantiate a new instance invocations.
Dispatcher Engine Threads :
(asynchronous activities : receive in mid-process, on Alarm, onMessage, wait) accolated to process asynchronous messages (durable process).

We can tune these values through OEM : Read the complete article here.

Oracle SOA Suite 11g Performance Tuning Cookbook

Oracle SOA Suite 11g Performance Tuning CookbookOracle SOA Suite 11g forms the heart of many organisations’ Service Oriented Architecture. Yet for such a core component, simple information on how to tune and configure SOA Suite and its infrastructure is hard to find. Because Oracle SOA Suite 11g builds on top of a variety of infrastructure components, up until now there has been no one single complete reference that brings together all the best practices for tuning the whole SOA stack.

Oracle SOA Suite 11g Performance Tuning Cookbook contains plenty of tips and tricks to help you get the best performance from your SOA Suite infrastructure. From monitoring your environment so you know where bottlenecks are, to tuning the Java Virtual Machine, WebLogic Application Server, and BPEL and BPMN mediator engines, this book will give you the techniques you need in a easy to follow step-by-step guide.

Starting with how to identify problems, and building on that with sections on monitoring, testing, and tuning, the recipes in this book will take you through many of the options available for performance tuning your application.

There are many considerations to make when trying to get the best performance out of the Oracle SOA Suite platform. This performance Cookbook will teach you the whole process of tuning JVM garbage collection and memory, tuning BPEL and BPMN persistence settings, and tuning the application server. This book focuses on bringing together tips on how to identify the key bottlenecks in the whole SOA Suite infrastructure, and how to alleviate them.

The Oracle SOA Suite 11g Performance Tuning Cookbook will ensure that you have the tools and techniques to get the most out of your infrastructure, delivering reliable, fast, and scalable services to your enterprise.

Looking for additional SOA books or if you have published a book, please feel free to add it to our publications wiki!

Improve performance and maintenance of heavily used SOA composites by Cattle Crew

As stated in a previous post, heavily used transient BPEL processes should be configured with some well-defined parameters in order to avoid storing too much data in the database, thus optimizing performance.

However, even if BPEL processes inside the composite are configured this way, data of other components like mediators and the composite itself are all stored in the database. How much information is stored can be influenced by the audit level setting. As of documentation, the audit levels are defined as follows:

  • Off: No composite instance tracking and payload tracking information is collected. No more composite instances can be created. No logging is performed. Note that disabling logging and the display of instances in Oracle Enterprise Manager Fusion Middleware Control Console can result in a slight performance increase for processing instances. Instances are created, but are not displayed.
  • Development: Enables both composite instance tracking and payload detail tracking. However, this setting may impact performance. This level is useful largely for testing and debugging purposes.
  • Production: Composite instance tracking is collected, but the Oracle Mediator service engine does not collect payload details and the BPEL process service engine does not collect payload details for assign activities (payload details for other BPEL activities are collected). This level is optimal for most normal production operations.

faultsGenerally, the SOA Infrastructure audit level is set to Production or Development - depending on the environment – and the composites are set to inherit this audit level. In case of an intensively used composite this means that a lot of data is persisted in the database.
The audit level, however, can be overridden for every composite. Since the data from the transient, short-lived composites is not needed, the setting Off for the relevant composite should be an interesting option to consider. Three questions must be answered:

  • How much information is persisted from the composite instance?
  • How much information is persisted from the component instances inside the composite?
  • What happens in case of an error?

BPM 11g Performance Tuning Whitepaper published by Mark Nelson

I am happy to announce that our new BPM 11g Performance Tuning whitepaper is now available on OTN. To access the whitepaper please click here. This white paper captures real world best practices from actual performance tuning exercises across many real BPM implementations. It is referred as a ‘best practices’ because we have found them over time and over many engagements to give the best results.

The whitepaper has been under development for quite a while now, and has been through a heap of reviews and revisions. So it is great to finally get it and hopefully you will find it useful!

From reporting on tuning experiences, to writing, reviewing, and testing, many people have contributed to this whitepaper. I would like to thank the following people for providing their contribution to make it a great learning source:
Vikas Anand, Deepak Arora, Partricio Barletta, Heidi Buelow, Christopher Karl Chan, Manoj Das, Andrew Dorman, Pete Farkas, Mark Foster, Simone Geib, Kim LiChong, Ralf Mueller, Bhagat Nainani, Sabha Parameswaran, Robert Patrick, David Read, Derek Sharpe, Sushil Shukla, Kavitha Srinivasan, Meera Srinivasan, Will Stallard and Shumin Zhao.

I sincerely hope that I have not missed anyones name, but if I have, the error is entirely mine.

This whitepaper is meant to compliment the Performance and Tuning Guide in the Fusion Middleware documentation. Readers should also consult the excellent whitepaper on purging SOA/BPM 11g databases by Michael Bousamra with Deepak Arora and Sai Sudarsan Pogaru which is available on OTN here.

For those with an interest in BPM 10g, I remind you of our previously published BPM 10g Performance Tuning whitepaper, which continues to be available on OTN here.
