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).

An evening with Oracle Coherence and Oracle Data Integrator – on Compute Grids, JMS implementations and trickle feed
The other night I had an interesting dinner date: seated around me were an Oracle ACE Director (Mark) and two Oracle employees, experts on Oracle Coherence (Ewan) and Oracle Data Integrator (Craig) respectively. The dinner was the closing event for all presenters and ACE Directors attending the EMEA SOA Partner Community Forum, put together by JÃ¼rgen Kress. A great event, a fine dinner and even better dinner conversation. Apart from discussing the Bejing 2008 and London 2021 (that is not a typo, the gentlemen were fairly pessimistic about the construction schedules for most Olympic venues), Dutch and British politics, American peculiarities, the wonderful Dutch countryside etc. we inevitably found ourselves back on the topics most on our minds: grids and clustering, message and data transport and the likes.
