The team behind DBNexus
DBNexus is taught by DBAs who still live on production floors — not a slide deck. 12+ years of real Oracle database administration, and teaching since 2012. This is the story, the philosophy, and the experience you're learning from.

Taught by working Oracle DBAs
DBNexus is taught by working Oracle DBAs, not full-time presenters. For 12+ years our instructors have managed real production databases — the kind where a single mistake during a 2 AM patch window costs lakhs per minute and wakes up the whole business. Node evictions on live RAC clusters, switchovers on Data Guard under pressure, queries tuned mid-crisis during month-end batches, estates patched and upgraded from 19c towards 26ai — that production scar tissue, knowing what actually breaks and how you recover, is what we bring into every class.
We started teaching in 2012 because most Oracle "training" out there was slideware: theory, screenshots, and certifications that fell apart the moment a learner touched a real server. So we built the opposite. Every concept in a DBNexus course is tied to a hands-on production scenario you'll actually face on the job — install it, break it, recover it, explain it in an interview. That's the production-first philosophy the whole business is built on: you don't learn slides here; you learn the job.
DBNexus grew out of that mission. What began as ORADBA Online Training & Support is now DBNexus Training & Consulting Pvt Ltd, based in Thane, Maharashtra — and our senior DBAs still teach every live weekend session themselves. Over 10,000 professionals across 40+ countries have trained with us, and 18,000+ of you follow the free lessons on YouTube. Whether you join a live batch, a recorded course, or call us for on-job DBA support, you're learning from DBAs who are still doing the work.
