It 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 (126.96.36.199) 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 >
Last night, the AMIS Mobile Special Interest Group convened. This session had as objective to explore the many different mobile agents and devices that we encounter, the types of signals, information and functions that are relevant with these various agents and the impact their inclusion in the mobile sphere of our customers has on the enterprise applications and architecture.
Our guest speaker – Rolf Hut of the Faculty of Civil Engineering and Geosciences – did an excellent job of introducing a new class of mobile agents with his presentation on hydro-meteorological stations. He even had us all build rain-sensors, from easily accessible and very cheap materials. 10 minutes of super-glueing, soldering and kindergarten-level handcrafting was all it took for 6 teams to create a sensor that could be connected to a laptop to register simple signals.
From this very practical example, it was not hard to envisage a wide network with hundreds or thousands of devices that report findings – to be processed by the backend infrastructure.

JavaOne 2010 presentation: Why and how to engage a Complex Event Processor from a Java Web Application0
In preparation for our Oracle Open World session ‘Xenogenetics for PL/SQ – Infusing with Java Best Practices and Design Patterns’ – I have been doing a little work on Advanced Queuing in the Oracle RDBMS, as well as on Java Stored Procedures. The objective of this presentation is to bring best practices, design patterns as well as new functionality to the world of PL/SQL from other worlds, such as Java. Interaction between database applications and the rest of the world is an important part of that. And such interaction, especially when we have a need for decoupled interaction, which we frequently should have, Advanced Queues will be used at the database end to support that interaction.
The concept of queuing – and more generally: messaging – has its Java counterpart in JMS, the Java Message Service. The question I then asked myself is: how exactly can I map AQ to JMS and how can I link the two worlds. How can I expose the AQ Queue or Topic in the RDBMS as a JMS Queue or Topic? And how can I consume messages from JMS into the database, possibly to AQ?
One of my reasons for making the connection between AQ and JMS has to do with another presentation at OOW I will deliver, More >
This article contains the resources for an article on Complex Event Processing (using Oracle CEP) that is published in the March 2010 issue of the Dutch Java Magazine. This article describes the interaction between CEP and Java Applications, using examples of temperature sensors that are monitored (aggregating their readings and looking out for any broken sensors) and web shops that try to determine the most popular and the most efficient search terms as well as the search terms that are quite useless (as they never result in a transaction).
The article is in Dutch – it will be made available for download later on. Note that it is based on Chapter 19 in the upcoming Oracle SOA Suite 11g Handbook (Oracle Press, due Summer 2010).
