The Oracle Instructor

This is my 3e-Approach to teaching (and posting):

Explain complex technical topics in an easy understandable way

Exemplify whenever possible with reproducible demonstrations

Empower the recipients to make use of the shown topic themselves effectively and efficiently

Why you won’t waste your time here:

As Senior Principal Instructor, I got promoted to the highest internal grade (IC5) that an instructor of Oracle University can reach.

Elections to the Leadership Circle – a corporate award for the best instructors worldwide, based on customer feedback – in 2009, 2012,  2013 and twice in 2015 show that attendees were very pleased with my teaching.

The highest available Oracle Certification also indicates that I probably know what I’m talking about.

On the other hand, you are of course not supposed to follow blindly my claims. When I say “Don’t believe it, test it!”, that means two things:

Don’t believe me (or any other expert, for that matter) just because I say it is so or so – I could be wrong. Although I will always state things after the best of my knowledge and even provide examples about it, an Oracle Database is a very complex and also rapidly evolving animal, so it could be wrong in spite.

Also don’t believe something about Oracle Databases yourself unless you have tested that belief. Good examples: Don’t believe your backup is working. Test it – before you actually need it. Don’t believe your Performance Tuning task was successful, test it by comparing the present state with a baseline you took before the tuning activity. Don’t believe that things behave in the same way now like you were used to know from an older version.
