IBM Websphere Portal 8: Web Experience Factory and the Cloud

Overview of this book

IBM WebSphere® Portal is a cost- effective, scalable, and proven solution for the portal enterprise space. Given the depth and the breadth of WebSphere Portal and the challenges of developing a portal project, you need a book that covers all the nuances of the entire portal project lifecycle. This book accomplishes just that. In this book, we cover topics that range from portal assessment, governance, and architecture, to design and development. These topics are covered not only within these traditional areas, but also within the cloud environment context. Keeping both contexts in mind, several chapters are dedicated to portal and portlet testing, troubleshooting, performance monitoring, best practices, and tuning. The cloud option is also analyzed and discussed for hosting, developing, and publishing portal applications. We also cover Web Experience Factory (WEF) as the tool of choice for portlet development. We take you from the introduction to the development of advanced portlets in an intuitive and efficient manner. We cover not only common topics, such as builders, models, and user interface development, but also advanced topics, such as Dojo builders, Ajax techniques, and WEF performance. Within the WEF space, we cover other topics, which have never been covered before by any other competing book. You will learn how to develop multichannel applications, including web mobile applications and you will learn about the model types available for portlet development, including when and how to utilize them. We also present and discuss numerous aspects and facets of implementing a WEF project and what it takes to successfully deliver them. The richness and the profundity of the topics combined with an intuitive and well-structured presentation of the chapters will provide you with all the information you need to master your skills with the IBM WebSphere Portal project lifecycle and Web Experience Factory.

Preface

Performance-related log files


WEF provides a large number of log files to help you analyze and troubleshoot your application. Out of these files, the three most important files for performance-related matters are as follows:

  • Model Actions

  • Server Stats

  • Session Size

Model Actions log file

The Model Actions log file is an excellent starting point to learn about performance aspects of your application. This file lists all the WEF actions that take place when the user interacts with your portlet. By analyzing this file you can extract important information about the time each action takes to execute. Such data should easily identify slow performing actions in any portlet. The analysis should be performed on individual portlets for each individual user interaction.

The Model Actions log file is entitled modelActions.txt. It is located in the WEB-INF\logs directory of your WAR file. By default, the logging action to this file is disabled. To enable logging of actions and their respective times...
