If users are not using your application as expected, then you need to mimic their behavior in a preproduction environment, perform a new performance tuning exercise, and execute a new capacity assessment. Predicting exactly what your users will do and how they will use your application before you present it to them is impossible, but detailed analysis of use cases can increase your predictions’ accuracy. For example, a large automotive company once experienced memory leaks in production that could not be reproduced in preproduction.
Finally, historical data recorded from application usage and user behavior can aid in trend analysis and forecasting application server topology and configuration changes. Trend analysis and forecasting with identified trends is an art in and of itself, therefore Chapter 12 is dedicated to guidelines you can apply to such efforts. The Role of the Java EE System Administrator Because databases are complex pieces of software the role of the database administrator (DBA) emerged to manage them. Java EE environments are similarly complex, and the Java EE system administrator role is slowly evolving to manage them.
Application Production Troubleshooting and Triaging Chapter 11 explores a formal production support methodology, but, at this point, simply know that the role of the Java EE system administrator is vital to troubleshooting production issues. When a production issue occurs, the first step is to triage the problem to identify the subgroups within an organization that own the problem. Triaging is the process of identifying the component within an enterprise application (such as the application code, application server, database, Web server, or legacy system) responsible for the issue.
