Overview of this book

Oracle SOA Suite 11g is the backbone of messaging and application integration in a service-oriented architecture. An application administrator is responsible for an end-to-end administration and management of the infrastructure. Understanding the underlying components, services, and configuration and their relations to each other is necessary to effectively administer the Oracle SOA Suite 11g environment. Due to its sheer size, administering Oracle SOA Suite 11g is a daunting task.This book provides detailed explanations of all the core administrative and management activities around Oracle SOA Suite. It includes compact information for end-to-end administration of Oracle SOA Suite 11g. It delves into advanced topics such as silent installs, cloning, backup and recovery and high availability installations.Using this book, you will be able to administer and secure your Oracle SOA Suite services and applications. You will follow examples that you can use in your everyday life as a SOA Suite administrator. The book begins with managing composite applications, their deployments and lifecycles and then moves on to monitoring instances, service engines, Weblogic Server and composite applications. With a detailed coverage of topics like the administration of individual service components as well as configuring MBeans using both Oracle Enterprise Manager Fusion Middleware Control and WLST-based scripts, you will be equipped to work with any services and applications.Towards the end, you will be taken through identifying faults & exceptions, troubleshooting approaches, and securing various components.

However, there are composite application design time considerations that should be addressed, otherwise improperly designed composites may degrade the overall performance regardless of how tuned your infrastructure is. As an administrator, having fundamental knowledge of these design time considerations is recommended.

Over the life cycle of a BPEL instance, the instance with its current state of execution might be saved in the database multiple times. This can incur considerable overhead. There are roughly two cases leading to an instance getting stored in the database:

  • When the instance is waiting for an event (wait, onAlarm, pick, and so on), the instance is dehydrated to the database. Later when the event happens (alarm expires or the message comes in), the instance is rehydrated and resumes...
