OraxarO

OraXarO is a visualization and reverse-engineering toolkit for exploring Oracle Database Internals
designed to inspect, decode, and visualize internal database structures such as processes, storages, and instance details
It provides both a REPL CLI and a web interface to interactively explore Oracle internals in real-time.

⚠️ Disclaimer: OraxarO is an educational and research tool. It is not affiliated with, endorsed by, or derived from Oracle Corporation.
Do not use it on production databases. Always analyze copies of files from a non-running database.

Contributing

Contributions are highly encouraged!
At this stage, we don’t have a fixed program or rigid direction — we’re open to new proposals, ideas, and experiments to make OraxarO a better and more insightful Oracle reverse-engineering toolkit
If you have thoughts or prototypes that can enhance OraxarO's capabilities,
please open a GitHub issue or pull request — we’d love to explore it with you.

⚠️ Safety Notes

• Work only on offline copies of datafiles (after shutdown immediate)
• Do not analyze or copy production datafiles
• Educational use only — for understanding Oracle’s internals
