No matter how experienced an Oracle DBA is, there is a huge amount of information that simply cannot be committed to memory, but must be looked up. Examples include details of Oracle architecture, configuration parameters, the syntax of a particular SQL statement, and perhaps the options for an Oracle utility. Part II of this book organizes this vast array of information into relevant chapters that are designed to make it easy for the DBA to quickly find accurate information for the task he or she is working on.
An experienced DBA knows that a well-managed Oracle database doesn’t just happen. It takes planning—lots of planning. In the remainder of this chapter, we’ll provide you with a high-level look at Oracle. We will introduce the Oracle architecture and discuss some options for licensing the Oracle software. Finally, we’ll provide you with many questions, and show you how to implement your database based on your answers.
