Chapter 11. Oracle and Hardware Architecture
In Chapter 2 we discussed the
architecture of the Oracle database, and in Chapter 6 we described
how Oracle uses hardware resources. Although Oracle operates in the
same way on many hardware platforms, different hardware architectures
can ultimately determine the specific scalability, performance
tuning, management, and reliability options available to you. Over
the years, Oracle has developed new features to address specific
platforms and, with Oracle Database 10g,
continues this process with a commitment to grid computing. This
chapter discusses the various hardware architectures to provide a
basis for understanding how Oracle leverages each of these platforms.
This chapter explains the following hardware systems and how Oracle
takes advantage of the features inherent in each of the platforms:
Uniprocessors Symmetric Multiprocessing (SMP) systems Clusters Massively Parallel Processing (MPP) systems Non-Uniform Memory Access (NUMA) systems Grid computing
We'll also discuss the use of different disk
technologies and how to choose the hardware system
that's most appropriate for your purposes.
