Fusion Middleware 11gR1 – Patch Set 5 is available (at last) – First impressions
0It had been announced at Oracle Open World 2011 and sort of promised for December 2011 – a promise or at least a suggestion reiterated in early December even. But for whatever reason, it slipped – not shipped – and Christmas break that perfect time of the year for playing with new software came and went. Now at last, it has arrived. As of midnight CET on 22nd February, PS5 (11.1.1.6) was published on OTN and eDelivery (https://edelivery.oracle.com/EPD/Download/get_form?egroup_aru_number=11493752) for download.
One of the reasons for the delay was the certification of FMW 11gR1 PS5 with Fusion Applications that was done over the last few months. Apart from the additional wait time (that is now over), this is quite good and important news: when Fusion Applications certifies software components, they put those components through very rigorous and extensive tests. Additionally, when Fusion Applications adopt a specific release – even a PS release – it makes that release more important to Oracle. So we now know that PS 5 has both been tested to the max and is of strategic importance to Fusion Applications and thereby to Oracle. Adopting PS5 for us mere mortals is therefore a safe bet – More >
Review of Oracle Service Bus 11g Development Cookbook (Packt Publishing) by Edwin Biemond, Guido Schmutz, Eric Elzinga et. al.
3Recently I gained access to an electronic copy of the just released Oracle Service Bus 11g Development Cookbook, written by five authors – all experts on OSB and three personal acquaintances of mine. I was very interested in learning about the final result after hearing many intermediate comments during the writing process as well as reading the occasional remark on Twitter. Knowing Guido, Eric and Edwin and assuming the same expert level for the other two authors, I anticipated a very interesting read.
Below I will share my impressions from browsing through this solid 500+ page volume. Note: the homepage for the book can be found here: http://www.packtpub.com/oracle-service-bus-11g-development-cookbook/book .
Implementing Web Services backed by a Database PL/SQL API using the Oracle Service Bus
1This article accompanies an article on the Architecture section of Oracle Technology Network (OTN): Implementing the Enterprise Service Bus Pattern to Expose Database Backed Services. It provides a detailed description of the implementation of the ESB architecture design pattern – the same that is introduced in the article on OTN – using Oracle Service Bus. This OSB based implementation is in terms of structure, architecture design and functionality the replica of the pure Java based implementation described in the OTN-article. OSB adds productivity, agility and many run time administrative benefits over the pure Java solution.
The challengeThe challenge the organization – let us call them Stuff Inc. – is facing is simple and common: external parties have requested access to information through Web Services. This information is held in the enterprise (Oracle) database at Stuff Inc.
The architecture team decides that the implementation of the service should be done according to the ESB architecture pattern.
Their initial implementation is based on custom Java Classes, XSLT stylesheets and JDBC calls.
After some time having worked with this initial set up, they decide to More >
Choosing the best way for SOA Suite and Oracle Service Bus to interact with the Oracle Database
0In the past few weeks, I have encountered a similar discussion in various organisations. Each organisation uses either SOA Suite (11g) or Oracle Service Bus (11g) at the core of their SOA infrastructure – either for integration purposes, for workflow and process orchestration or for both. In each organisation, the role of one or more databases is crucial and interaction between the SOA environment and the database is one of the most common and therefore important functions in their enterprise IT environment.
Given the importance, it is only logical that the way(s) chosen for linking the SOA component to the database is carefully selected – and evaluated every now and again. Technology may have progressed, experience may have taught us a lesson or two, the knowledge and skills may have evolved.
Interestingly enough, the number of ways for SOA Suite and OSB to communicate with the database is quite high. This article includes an illustration that shows over 20 different interaction channels that we can choose from with a fairly wild variation of attributes, required skills, productivity and performance characteristics.
Among the choices we face is the question of the communication More >

Ways to instantiate a variable in Oracle Service Bus based on a static XML document
4Today we had an interesting exploration into the many ways available in the Oracle Service Bus to load a piece of XML into a variable in a message flow – to use as the source for populating part of a to-be-forwarded request message to the business service or for enriching the response message. Even such a seemingly straightforward task turned out to have a number of ways to approach, each with their own merits and complexities.
The various approaches we uncovered in a space of ten minutes or so:
- use a static expression in an Assign action, simply copying the XML content into the variable
- use the function fn:doc that can load XML from a local file and assign the XML to a variable that way
- introduce the file adapter to load the XML file from the local file system and assign it to a variable; this would also support non-XML formats – like comma separated values – that can be converted to XML
- use the database adapter (or the fn-bea:execute-sql) to retrieve the XML content from a relational database
- store the XML content in an XQuery transformation
- do any of the above and wrap it inside a Proxy Service that can be invoked from from other services, potentially governed by the service More >
