Chapter 2: Understanding the Oracle Instance
The thing I want you to memorize if you haven’t memorized it yet, the definition of Oracle Instance i.e. the background processes and memory architecture constitute the Oracle Instance. To better understand these two things I want to give you the analogy of the way human brain works. Human brains works pretty much the same way Oracle Instance works.
