Introduction

The Oracle database engine has become a huge piece of software. This not only means that a single human can no longer be proficient in using all the features provided in recent versions, but it also means that some of them will rarely be used. Actually, in most situations, it is enough to know and take advantage of a limited number of core features in order to use the Oracle database engine efficiently and successfully. This is precisely why in this book I will cover only the features that, based on my experience, are necessary to troubleshoot most of the database-related performance problems you will encounter.
