jonathan Lewis's New book

i came across an advert on his web page for his new book due in november. weird evough neither apress not amazon has a listing for it . http://www.jlcomp.demon.co.uk/cbo_book/ind_book.html  you want to understand how Oracle’s Cost Based Optimizer works, you will want to read this book. With special thanks to the technical reviewers: Wolfgang Breitling and Christian Antognini.

The CBO is an extraordinary piece of software, but it depends on a model and it depends on a number of assumptions about how that model will behave at run-time. Sometimes the model isn’t realistic enough; sometimes the run-time activity doesn’t quite match the model. And just to make things that little bit harder to understand, sometimes the model, the run-time action, or both, will change as you upgrade your version of Oracle.  

......Expect it on the shelves in November 2005 – but if you are coming to the UKOUG annual conference, there should be some early copies on the Oak Table/Apress stand on 31st October
