After months of preparation and two adrinaline loaded days I have managed to pass the Oracle Certified Master Practicum; an email has come in today:

Dear  Martin,

Congratulations! on the successful completion of the Oracle DBA 10g Certified Master practicum.

Furthermore I am registered with Oracle, too: http://www.oracle.com/technology/ocm/mbach.html

I am immensely pleased to join the group of OCMs in England, this is indeed a career high so far.
