Of course, any one of these solutions is infinitely more valuable than not
implementing any of them and simply hoping that a disaster never happens to you.

Chapter 12 CHAPTER 12
Oracle and Hardware Architecture 12
In Chapter 2, we discussed the architecture of the Oracle database, and in Chapter 7,
we described how Oracle uses hardware resources. How hardware architectures are
chosen and deployed can ultimately determine the specific scalability, performance
tuning, management, and reliability options available to you. In fact, systems are
sometimes badly configured without consideration of the proper balance of CPUs,
memory, and I/O for projected workloads. This can limit options for database tuning
if performance later becomes an issue.
Over the years, Oracle has developed new features to address specific platforms and,
with Oracle Database 11g, continues this process by building on a commitment to
grid computing and information appliance-like configurations. This chapter discusses
the various hardware architectures to provide a basis for understanding how
Oracle leverages each of these.
