Introduction: Application profiling
Explore the key concepts pertaining to application profiling, a WebSphere extension for defining strategies to dynamically control concurrency, prefetch, and read-ahead.
- Application profiling
- Use application profiling to identify particular units of work to the WAS runtime environment. The run time can tailor its support to the exact requirements of that unit of work.
- Application profiling tasks
- Tasks are named units of work. They are the mechanism by which the run time environment determines which access intent policies to apply when an entity bean's data is loaded from the back end system.
- Automatic configuration of application profiling
- The Application Server Toolkit (AST) includes a static analysis engine that can assist you in configuring application profiling. The tool examines the compiled classes and the deployment descriptor of a Java 2 Platform, Enterprise Edition (J2EE) application to determine the entry point of transactions, calculate the set of entities enlisted in each transaction, and determine whether the entities are read or updated during the course of each identified transaction.
