About the Performance Tuning Guide

The BEA WebLogic^TM product family, composed of the BEA WebLogic Commerce Server^TM, BEA WebLogic Personalization Server^TM with Portal Framework^TM, and BEA Campaign Manager for WebLogic^TM, is designed to run on a range of server-class machines. Capacity planning is the process of determining the hardware types and software configurations required on these machines to adequately meet application needs. This document serves as a guide for capacity planning and performance tuning, specifically for solutions built with WebLogic Commerce and Personalization Servers, and Campaign Manager for WebLogic. It covers performance characteristics and capacity of specific application features (for example, login, update shopping cart, and so on), as well as specific guidelines for caching and other factors.

This document covers the following topics:

Chapter 1, "High-Level Architecture Model," presents a high-level architecture overview.
Chapter 2, "Load Testing Your Installation," provides information about load testing, plus a series of steps you can follow to test your installation.
Chapter 3, "Factors Affecting Performance," describes a number of factors that can affect performance.
Chapter 4, "Estimating Baseline Capacity Requirements," provides information about how you can use information from the previous topics to obtain a baseline environment for your specific system requirements.
Chapter 5, "Performance Tuning Tips," provides specific information about how to tune individual parts of your system.

Important Notes

Capacity planning and performance tuning are not exact sciences. Every application is different and every user behavior is different. This document is meant only as a guide for developing capacity planning numbers and will encourage you to err on the side of caution.

Any and all recommendations provided in this Guide should be adequately verified before a given system is moved into production. There is no substitute for adequately testing a prototype to obtain capacity planning numbers.
