This book contains information about configuring server and application settings to achieve the highest application performance. This book also describes implementation and design issues that affect performance.
This book is for advanced administrators and developers who are familiar with the basics of EAServer administration, development, and deployment.
Chapter 1, “Introduction,” explains key performance concepts, describes tools to test and measure performance, and provides techniques for measuring performance and identifying areas where your tuning efforts will have the greatest impact on overall performance.
Chapter 2, “Server Tuning,” describes how to configure server and system settings for best performance. These settings affect all applications, regardless of architecture.
Chapter 3, “Component Tuning,” describes business component settings and coding practices that you can optimize for best performance. These settings affect applications that call business components from the Web tier or directly from base clients.
Chapter 4, “EJB CMP Tuning,” describes how to tune the settings in the EAServer EJB CMP engine and EJB CMP component properties. These settings affect applications that use EJB entity beans with container managed persistence (CMP).
Chapter 5, “Web Application Tuning,” describes tuning and coding best practices to create high performance Web sites hosted in EAServer. These settings affect applications that serve static content with EAServer and make use of servlets and JavaServer Pages (JSPs) deployed on EAServer.
Chapter 6, “Database Access Tuning,” describes how to tune connection cache settings and the EAServer transaction manager, and provides coding best practices for interacting with remote databases. These settings affect applications that call remote database servers from business components, servlets, or JSPs deployed on EAServer.
Chapter 7, “Cluster Tuning,” describes how to tune application settings and code to obtain high performance and load balancing in a clustered (multi-server) deployment.
Chapter 8, “Message Service Tuning,” describes how to configure the messages service for maximum performance and explains best coding practices for high performance use of the JMS or message service APIs.
Chapter 9, “Using the Performance Monitor,” describes how to configure the EAServer Performance Monitor to prevent degradation of server performance under extreme load conditions.
