By | Database Administration & Monitoring, Oracle | No Comments

By Franck Pachot . This post starts a series about things I wrote while preparing the OCM 12c upgrade exam. Everything in those posts are written before taking the exam – so don’t expect any clue about the exam here. It’s based only on the exam topics, and only those points I wanted to brush up, so don’t expect it to be a comprehensive list of points to know for the exam. Let’s start by…
