I am a software engineer with nearly 30 years of experience in software development, passionate about solving various challenges in software development and operations. Over the past decade, I’ve independently researched Oracle database’s internal storage structures, becoming proficient in data file block formats, ASM internal principles and architecture, as well as conducting in-depth studies on redo log structures and their change vector formats.
I recently wrote an eBook about Oracle database internal storage formats, and I hope to reveal some deep insights into Oracle’s internal workings.This book is written for experienced database administrators and developers who are ready to go beyond the surface of Oracle database operations and explore the real internal structures that govern performance, storage, and behavior.
From the physical layout of data files to the granular organization of data blocks, this book provides an in-depth, technical look at:
The structure of Oracle data blocks and the relationships between their internal layers
How rows are stored, and how row chaining and row migration actually work under the hood
Clustered table block formats and segment header block anatomy
Index block structures and index search mechanisms
A detailed examination of IOT (Index-Organized Tables) and their data block layout
A deep analysis of LOB (Large Object) storage — both BasicFile and SecureFile — and how they are truly managed within Oracle
Insights into Oracle internals not documented in the official Oracle manuals
With a focus on raw storage formats, block internals, and LOB architecture, this book exposes hidden behaviors and undocumented features that can help you troubleshoot advanced storage-related issues, design more efficient schemas, and understand Oracle like never before.
Whether you’re optimizing performance, debugging corruption, or simply curious about how Oracle works at the binary level, this book is your guide to the internals Oracle rarely talks about.
