  • Garbage Collection for Java Distributed Objects
    GARBAGE COLLECTION FOR JAVA DISTRIBUTED OBJECTS by Andrei A. Dãncus A Thesis Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements of the Degree of Master of Science in Computer Science by ____________________________ Andrei A. Dãncus Date: May 2nd, 2001 Approved: ___________________________________ Dr. David Finkel, Advisor ___________________________________ Dr. Mark L. Claypool, Reader ___________________________________ Dr. Micha Hofri, Head of Department Abstract We present a distributed garbage collection algorithm for Java distributed objects using the object model provided by the Java Support for Distributed Objects (JSDA) object model and using weak references in Java. The algorithm can also be used for any other Java based distributed object models that use the stub-skeleton paradigm. Furthermore, the solution could also be applied to any language that supports weak references as a mean of interaction with the local garbage collector. We also give a formal definition and a proof of correctness for the proposed algorithm. i Acknowledgements I would like to express my gratitude to my advisor Dr. David Finkel, for his encouragement and guidance over the last two years. I also want to thank Dr. Mark Claypool for being the reader of this thesis.

  • Oracle's Commitment to the Eclipse Community
    Oracle’s Commitment to the Eclipse Community An Oracle White Paper March 2007 INTRODUCTION Eclipse has gained strong market adoption for core Java development and is adding support for other languages as well. It enjoys great popularity, in part because it’s free, but also due to its extensibility via plug-ins and the strong ecosystem around it. The advent of emerging trends and technologies like Web 2.0 and SOA amplified the need for an integrated and comprehensive Java IDE that provides pre- packaged and tested support for all major Java EE 5 and Web services standards. Oracle’s tools vision is “productivity with choice”. This means making application development for the Oracle platform as easy as possible regardless of what toolset developers employ be it Oracle JDeveloper or Eclipse. Oracle’s JDeveloper provides a great out-of-the box user experience and dramatically increases productivity for building Java Enterprise Edition (Java EE) and SOA based applications. For various reasons, some Oracle customers elect to use Eclipse for Java development. We believe those users should get similar productivity that other Oracle users are already enjoying with JDeveloper. That’s why Oracle chose to join the Eclipse Foundation as a Strategic Developer and Board Member, and contribute world class talent to lead a variety of Eclipse projects and address its customers' needs. EVOLVING REQUIREMENTS Three major enterprise computing trends are coming together to form a new platform for application development. These trends are Java EE 5, Service Oriented Architecture (SOA), and Web 2.0. Today, end users expect highly interactive user interfaces with real-time updates and desktop-like capabilities.

  • Enabling Application Lifecycle Development in Jdeveloper
    Enabling Application Lifecycle Development in JDeveloper Susan Duncan Oracle Corporation United Kingdom Keywords: Application Lifecycle Management,ALM, JDeveloper, Team Productivity Center, SCM, Versioning Introduction Application Lifecycle Management has been defined as “The process of delivering software as a continuously repeating cycle of inter-related steps.” It can be described as the management of the lifecycle development practices (requirements, build, test, change control, defect management etc) integrated together through application of process, reporting, traceability and collaboration. The better this integration, the better the software. However, in the past many of these practices worked in isolation - in functional silos that did not lend themselves to collaboration. But collaboration has become increasingly necessary in the software development world where teams work across organizations, time zones, cultures and business functions. Oracle Fusion Middleware encompasses a number of features to facilitate this mode of distributed working where collaboration is paramount including remote deployment and debugging, a shared resource catalog, SCM system integration, built-in testing with JUnit, functional, load and test management with Oracle Application Quality Management Suite and lifecycle management of SOA composites with ClearApp. This paper concentrates on some of the practical ALM features that are available to the application developer using JDeveloper in her day-to-day working environment Versioning One of the most obvious areas of ALM is versioning or source code management. It would be obvious to say that every development team’s process includes SCM. Generally there are two main types of versioning systems: Lock – Modify – Unlock Although a very safe and reliable system this is not necessarily best suited to a distributed development team.

Each feature could be ranked as “excellent, “very good” “adequate”, “needs improvement” or “NA”. During processing, the first four rankings were assigned a numerical value according to their relative significance. The last value (“N/A”) was discarded. Values were then combined to produce a score for each element for every IDE and also for an overall total score.

  • Performance Implications of Memory Management in Java
    Proceedings of the 5th WSEAS International Conference on Telecommunications and Informatics, Istanbul, Turkey, May 27-29, 2006 (pp51-56) Performance Implications of Memory Management in Java DR AVERIL MEEHAN Computing Department Letterkenny Institute of Technology Letterkenny IRELAND http://www.lyit.ie/staff/teaching/computing/meehan_avril.html Abstract: - This paper first outlines the memory management problems that can arise in Java, and then proceeds to discuss ways of dealing with them. Memory issues can have serious performance implications particularly in distributed systems or in real time interactive applications, for example as used in computer games. Key-Words: - Garbage collection, Java, Memory management. 1 Introduction 2 Memory Management Problems Problems with memory management range from In the context of programming, garbage is any slowing execution to system crashes, and are structure allocated in heap memory but no longer in considered so serious that Java provides automatic use, i.e. there is no reference to it from within garbage collection. While this removes some of the program code. Automatic GC removes the problem problems many remain [1]. Java memory of dangling references where memory is marked as management issues are especially relevant for free for re-use while active pointers still reference it. developers who make significant use objects that reference large structures on heap memory or where In Java the remaining problems are space leaks and rapid or consistent execution speeds are important. slow or varying computation. Scalability is an This applies in particular to the gaming industry, important property of applications, but even if the interactive real time applications, and to enterprise program is scalable in all other aspects, its GC may systems.[2].
