Wolfgang Breitling

Wolfgang Breitling was born in Stuttgart, Germany, and studied mathematics, physics and computer sciences at the University of Stuttgart. Following several years as systems programmer for IMS and later DB2 databases on IBM mainframes, he got on the project to implement Peoplesoft on Oracle. In 1996 he became an independent consultant specializing in administering and tuning Peoplesoft on Oracle. The particular challenges in tuning Peoplesoft, with often no access to the SQL, motivated him to explore Oracle's cost-based optimizer in an effort to better understand how it works and use that knowledge in tuning. He has shared the findings from this research in papers and presentations at IOUG, UKOUG, local Oracle user groups, and other conferences and newsgroups dedicated to Oracle performance topics.
