Story
Introduction
I've been working as an Oracle DBA for over 10 years. I spend most of my time designing, implementing and managing Oracle databases. In my spare time I play with linux, virtualization, open-source and Oracle technologies in addition to my three boys. I also have a lovely and gracious wife who allows me to do these things.
