Chapter 12. Optimizing, Fine-tuning, and Monitoring

In this chapter, we will cover:

• Using Update Batching for entity objects

• Limiting the rows fetched by a view object

• Limiting large view object query result sets

• Limiting large view object query result sets by using required view criteria

• Using a Work Manager for processing of long running tasks

• Monitoring the application using JRockit Mission Control

Introduction

The ADF framework offers a number of optimization and tuning settings related to entity objects, view objects, and application modules. Many of these settings are accessible in JDeveloper in the General tab Tuning section of the corresponding Overview editor. Others are programmatic techniques that optimize the performance of the application, such as limiting the result set produced by a view object query, or providing query optimizer hints for the underlying view object query. Yet more are implemented by utilizing facilities offered by the application server, such as the use of work managers...
