       Professionals Whose Businesses Depend on Application
                            Performance

DETROIT, March 13, 2012 (GLOBE NEWSWIRE) -- Compuware Corporation
(Nasdaq:CPWR), the technology performance company, today announced the
availability of Java Enterprise Performance, a new online eBook
authored by technology experts at the Compuware dynaTrace(R) Center of
Excellence. Java Enterprise Performance is a free resource for IT
senior managers, team leaders and practitioners responsible for the
performance of business-critical applications. To start reading, visit:
http://book.dynatrace.com.

The online book is a comprehensive compilation of state-of-the-art
approaches, best practices and pragmatic solutions to support
application performance management and optimization initiatives
throughout the lifecycle of systems from pre-production to production,
encompassing all stakeholders: architecture, development, test,
deployment and production teams.

"As businesses rely more than ever on applications, application
performance management (APM) has become a top operational priority;
performance delays of just two seconds can cause a revenue loss of 4
percent," said Alois Reitbauer, co-author and dynaTrace Technology
Strategist. "As interest in application performance grows, more people
want to further their careers in this field. Our eBook provides a
pragmatic reference for those who are passionate about application
performance and accountable for improving it."

All key topics covered in Java Enterprise Performance -- from
application performance concepts and memory management to hot issues
such as cloud, virtualization and more -- will empower architects,
developers, test and operations teams to understand, measure and
optimize the performance of Java-based technologies and meet the
challenges they currently face in complex enterprise environments. The
eBook is being published online with new chapters added monthly.

The first two chapters are available today:


  --  Chapter One -- Application Performance Concepts: considers how to become
      performance experts. Besides technical expertise, IT leaders need a
      solid understanding of how performance and scalability works. The
      chapter reviews how to collect and interpret data properly and which
      performance data is needed in a variety of use cases.

  --  Chapter Two -- Memory Management: addresses the fact that memory
      management is often a major contributor to application performance
      problems. It highlights the inner workings of memory management and
      garbage collection to help understand memory-related performance
      problems such as memory leaks or excessive garbage collection, where
      they come from and how to optimize applications accordingly.
