SOA Suite 11g Composites and Error Hospital, be aware!

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 !!

OSB 10gR3 and SWA and MTOM

This blog is about using soap with attachments and the use of MTOM within the OSB (10gR3). A service is created that accepts a soap with attachment (DocumentService) and translates it to a service that accepts a binary element. MTOM is used for performance reasons for the second. Some notes: * For the use of attachments you need RPC-style document instead of the usual document-style. This due to the fact that the document-style limits a message to a single . * A service can not have both SWA and MTOM within OSB. First a WSDL is setup for the DocumentService: The $attachments variable holds the attachments and the body holds the attachment data. Also other data is stored within the attachment element (see h

Book review: Data Management at Scale (Piethein Strengholt)

 This blog is a review of the book "Data Management at Scale (See also at bol.com ) Data Management is a hot topic nowadays and this book does a fantastic job at adding value to this topic. It is a must read and one of the few technical books I finished reading in a weekend. The book gives a fantastic overview on how to implement a Data Mesh data architecture. The Data Mesh concept is explained by Martin Fowler here . The book is a good mix between conceptual and implementation architecture level. It gives a lot of examples of how this architecture at scale can work, for both small and big companies. It is practical and I used it to implement it at one of my customers. The book describes an architecture in which the focus is on the DIAL (Data- and Integration Access Layer).  On a high level the book covers the following topics: The key principles for data management at scale - Domain-Driven Design  - Domain Data Stores - Meta data management Ready Data Store The concept of servin
