About me / Contact me


My name is Harald van Breederode and I am a DBA trainer working for Oracle University in The Netherlands. My primary job role is to train Oracle Database Administrators (DBA) in using the Oracle database and associated products such as Oracle Enterprise Linux. I am an Oracle Certified Professional (OCP) on Oracle8i, Oracle9i, Oracle10g and Oracle11g. I am also an Oracle Certified Master (OCM) on Oracle10g and Oracle11g.

I am specialized in Oracle High Availability products including Real Application Clusters and Data Guard. I have 25+ years Unix Operating System experience and more than 10 years of Oracle experience.

I am a regular speaker at various User Group conferences and finally I am a member of the OakTable Network.

About this Blog

I will use this Blog primarily to discuss Oracle database related topics of interest to DBA students attending classes I teach at Oracle University, but others might benefit as well.

Because I am blind I will also discuss accessibility related issues I encounter in my professional life as a technology trainer as well as in my personal life. Hopefully my experiences are beneficial to other visually impaired persons and I can save them the trouble of inventing the same wheels as I did.

My intention is to post a couple of times each month and share useful information with you. I have uploaded my user group presentations and articles I (co-)wrote over the last few years.
