Welcome to my site

My name is Stefan Oehrli. I’m a Swiss electrical engineer working since several years as an Oracle DBA. My main interests are backup & recovery, database internals, database security, infrastructure management and other stuff coming across my daily work as a DBA. On this website I share my experience and some of my thoughts in these areas with you. Among other things, you find my blog, a few scripts, links to some papers and presentations I have written or co-authored, list of public appearances as well links to other interesting web resources.
