Support Marcus Oliveira

I’m a database engineer and developer passionate about Oracle Database internals. Over the years, I’ve built a variety of tools, scripts, and utilities that make it easier for DBAs and developers to:

Monitor performance in real time

Analyze wait events and SQL execution

Explore compression and storage optimizations

Navigate complex dependencies between tables, views, and partitions

Most of what I share is the result of hands-on experience solving real-world Oracle challenges—things like uncovering bottlenecks, tuning SQL, etc.

By supporting me here, you’re helping me:

Dedicate more time to building and improving these tools

Share detailed guides, scripts, and examples with the community

Keep everything free and accessible for Oracle professionals everywhere

If you’ve ever used one of my scripts, learned from a snippet I posted, or simply want to encourage more deep dives into Oracle, a coffee (or two) goes a long way.

Thank you for being part of this journey and helping make the Oracle community stronger!
