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 “GAPP” 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 “GAPP” special:

  • The method can analyse the full infrastructure, so from front-end to back-end
  • The method is not focussing on one More >
