Overview

What this course is about

Oracle is the database engine behind a huge share of banking, ERP and enterprise systems, and administering it well is a specialised, well-paid skill. This 2-month Oracle DBA -OCA Level programme takes you from the basics to being genuinely useful.

Expect to spend most of your time actually doing the work — you’ll install and configure Oracle database instances and manage tablespaces, users and privileges along the way.

Every session is one-on-one, so the pace bends to you — not to a class average.
