Oracle Core: Essential Internals for DBAs and Developers by Jonathan Lewis provides just the essential information about Oracle Database internals that every database administrator needs for troubleshooting—no more, no less.
Oracle Database seems complex on the surface. However, its extensive feature set is really built upon upon a core infrastructure resulting from sound architectural decisions made very early on that have stood the test of time. This core infrastructure manages transactions and the ability to commit and roll back changes, protects the integrity of the database, enables backup and recovery, and allows for scalability to thousands of users all accessing the same data.
Most performance, backup, and recovery problems that database administrators face on a daily basis can easily be identified through understanding the essential core of Oracle Database architecture that Lewis describes in this book.
Provides proven content from a world-renowned performance and troubleshooting expert
Emphasizes the significance of internals knowledge to rapid identification of database performance problems
Covers the core essentials and does not waste your time with esoterica
What you’ll learn
Oracle's core architectural foundations
How much overhead is reasonable
How to recognize when you're doing too much work
How to predict bottlenecks and why they will happen
How to minimise contention and locking
Why concurrency can slow things down significantly
Who this book is for
Oracle Core: Essential Internals for DBAs and Developers is aimed at database administrators ready to move beyond the beginning stage of doing work by rote towards the mastery stage, in which knowledge of what needs to be done comes not from a set of recipe-style instructions, but rather from the intimate knowledge and understanding of the system to be managed. Experienced database administrators will also find the book useful in solidifying their knowledge and filling in any missing pieces of the Oracle Database puzzle.

很多事情,你可能很困惑,为啥一个并发控制,有这么多概念:enqueue,lock,latch,pin。为啥会有library cache lock latch,为啥要引入mutex,如何通过redo/undo实现acid,保证读写互不阻塞,为啥parse这么耗资源,在rac下为啥要小心sequence和unique index等待,非常有料,等...

评分去年大概8月份的时候, 我看完了Cost-Based Oracle Fundamentals,在SQL Tuning方面,我是藉由这书入门的,一本经典好书可以帮助提升在某一方面的层次。之后我想找Jonathan Lewis的一本更旧十年前的书看 – Practical Oracle8i™: Building Efficient Databases,当时还在豆瓣...
