My next project is probably a Oracle SOA Suite 11g project, so start reading the following book. A review of the book will follow ( http://www.packtpub.com/oracle-soa-suite-11g-administrators-handbook/book ) I hope to read useful information about How to set up Oracle SOA Suite projects How to unit test How to deploy to DTAP How to monitor How to error log How to govern

One of the better features of the Oracle SOA Suite 11g is the Error Hospital in which errors are handled uniformly accross SCA components. But you have to think twice before you use error retry mechanisms for a Composite within a SOA! This because a Composite (or Service) can be used within Service Compositions. This is one of the Service Oriented principles (as can be read within the books of Thomas Erl). So a Service is not aware in which context it is (and may be) used. It can be part of a Business Service. So the Service can not decide how to handle errors and can certainly not have a manual recovery, because in some context this will be wrong. Just be aware that your SCA Composite can always be a Service Composite member !!

I got this book on the second SOA Symposium in Rotterdam from one of the authors (Manas Deb) who happen to give a presentation there on SOA, BPM and EDA. He signed the book, so I have a unique piece :) This book gives you a prefect head start with the Oracle SOA Suite 11g. It explains the concepts of SCA, Database-, JMS- and File Adapter, BPEL, Human Tasks, Business Rules, OSB, Unit test of composite SCA applications, Security, Exception Handling, BAM, Event Delivery Network, SDO and B2B. All these concepts are explained with small tutorial examples. If you want to have in depth knowledge of the SOA Suite, this is not the correct book.

I bought this book to get a global overview of the possibilities of SCA, because it is also implemented within the Oracle SOA Suite 11g. It is the first book on the fairly new SCA standard. If you want to get a global overview the first chapter will already do. The next chapters go deeper into the concepts with Java as the example programming language. Chapter 1 - Introducing SCA The book starts with a global introduction of SCA and its place w.r.t. SOA, J2EE, .NET, Spring and distributed computing. SCA focuses on being able to describe assemblies of components which have been written in a variety programming models and protocols . It does not cover presentation and persistency. Within this chapter the main terms are explained: Service , Component , Composite and Domain . Why another standard? Because there are still some issues with J2EE and .NET, namely complexity and reusability. You have to understand a lot of different technologies like JAX-WS, JMS, EJB, ASP.NET, .NET M...

This post guides you through the installation of the Oracle SOA Suite 11g with JDeveloper 11 with the use of Oracle XE database (for Windows). Note: It is assumed that Oracle XE database is already installed. Required downloads Oracle Weblogic Server 10.3.1   SOA Suite   Repository Creation Utility JDeveloper Studio The detailed steps are nicely described here . The next picture gives a nice overview of the directory structure created. Step1 -  Create Schemas for Oracle SOA Suite and Oracle BAM (RCU) Unzip the files Run bin/rcu.bat At the Database Connection Details fill in the XE details. If you encounter the next fault you have probably not started the XE database.   Ignore all warnings Click OK Select all components I ran into the following problem: When you click Ok you see the following error: And this is about the Processes DB Init parameter that is wrong. To fix this goto the Database Home page, Sql Editor and execute the follo...
