7 Configuring and Using Memory

This chapter explains how to allocate memory to Oracle Database memory caches, and how to use those caches. Proper sizing and effective use of the Oracle Database memory caches greatly improves database performance. Oracle recommends using automatic memory
management to manage the memory on your system. However, you can choose to manually adjust the memory pools on your system, as described in this chapter.

This chapter contains the following sections:

Understanding Memory Allocation Issues

Configuring and Using the Buffer Cache

Configuring and Using the Shared Pool and Large Pool

Configuring and Using the Redo Log Buffer

PGA Memory Management

Managing the Server and Client Result Caches
