The ultimate ADF event of 2012: The AMIS Master Class Advanced ADF – Christmas Special (Friday 21st of December)0
If you are an ADF developer – and The Netherlands are within reach for you – then Friday 21st of December is a day to mark in your diary. On that day, the shortest of the year in our Northern Hemisphere, we present the Advanced ADF Master Class – in the spirit of the holiday season.
and more like the Magnificent Seven than like Snow White’s dwarfs. Each is an ADF specialist who is committed to deliver an inspiring talk on his specific expertise within the ADF domain. This event is unique – bringing together ADF specialists in a special, intimate Christmas atmosphere – and with Dutch Christmas treats as icing on the cake. The topics are all based on real life experience. The concepts discussed and the approaches demonstrated have immediate practical value. The setting lends itself to up close and personal interactions, discussions and deep dive explanations.
It is a wonderful opportunity for ADF developers as well as application architects to get inspired in various essential areas of ADF, to acquire knowledge and insights that are applicable back on the job and to exchange ideas and experiences with peers – all in a seasonal More >
Performance of Enterprise Java Applications is a requirement and usually a challenge. Business requirements on systems can be stiff, successful systems can easily be overloaded and complex application architectures can add a burden too. Improving performance by tuning the application after it has been built seldomly renders huge improvements. By taking a step back – or even two – and regarding the application and the performance from a distance, it becomes possible to really design and architect for performance according to the ISYITF-method: it is staring you in the face. Order of magnitude improvements are attainable through logical reasoning and careful application of multi-tier architecture principles and JEE platform facilities.
This is the abstract for the session Thinking Through Java Enterprise Performance that I will be presenting on Tuesday October 2nd at JavaOne 2012 (BOF 4712 4:30 PM – 5:15 PM – Parc 55 – Cyril Magnin I.
Bloom Filters, Hierarchical Profiling, Synopses & One pass distinct sampling, jumping the GAPP … – feast for DBAs (considered harmful..)
It’s Monday night and a select company of DBAs and Database developers have gathered at AMIS HQ in Nieuwegein for the ‘Looking Back at Hotsos 2009′ session. It is one of those sessions that has a lot of energy, laughter and a wealth of serious content. Four very experienced speakers relate their best experiences and most important learning points from the Hotsos conference. And the audience is allowed to participate. Speakers are Marco Gralike, Toon Koppelaars, Gerwin Hendriksen and Jeroen Evers.
The evening brings us – apart from a quite good dinner – interesting topics such as Bloom Filters, Hierarchical Profiling,..

Sunday 21 September 2008 at Oracle Open World, I had the opportunity to present my method "GAPP" once more (HOTSOS 2008 and Planboard may 2008). This time I also mentioned how the method can be used with Service Oriented Architectures (SOA). For people not knowing what "GAPP" is all about I give a small introduction to the method. I also like to tell you why I started with â€œGAPPâ€ in the first place and what the added value is of the method above other methods.
"GAPP" means General Approach Performance Profiling and can be used to find out where in your architecture the most wait time variance can be explained from your business process. "GAPP" makes it possible with very little data, in higly complex technical infrastructures, still be able to find the performance bottlenecks for a specific business process. The nice thing about the method is that it is not only able to pinpoint a bottleneck which is already there, it is also able to pinpoint a future bottleneck in a normal running system. This is something what only "GAPP" can do.
What makes â€œGAPPâ€ special:
- The method can analyse the full infrastructure, so from front-end to back-end
- The method is not focussing on one More >
Larry yesterday did his keynote here at Oracle Open World introducing the "Oracle(R) Exadata Storage Server". This morning I attended a session about the technical details behind the server. In principal the server works with 8 nodes running RAC on Oracle Enterprise Linux 5. For the storage management ASM is used and since 188.8.131.52 smart scan has been introduced. Smart scan has been designed for very big data sources used in queries, like in Data Warehouses, where tables from tera bytes are common. In principle the following is accomplished using smart scan: (more…)
