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
