JDK 6 Performance Update, WAS v7, Fix Pack 7, and the G1 Collector

The Fix Pack 7 release for WebSphere Application Server v7 includes the JDK 6 SR6 update. It will update Java to Java SE 6 Update 16.

If you have not upgraded your WebSphere application environment to JDK 6, here are the reasons that you should upgrade to the latest. You will see many improvements with performance, stability and scaleability. In addition to these benefits, Fix Pack 7 with SR6 includes the new garbage collector known as the Garbage First or G1 Collector. It is concurrent and parallel with more predictability and better useability. It splits the heap into regions and young and old generational spaces are organized in sets of regions.

New Redbook Published: "WebSphere Application Server V6.1 on the Solaris 10 Operating System"

SG247584 Redbook Cover The final version of the Redbook titled "WebSphere Application Server V6.1 on the Solaris 10 Operating System" has been published. In this book, we document how WebSphere Application Server V6.1 and Solaris 10 can be configured, optimized, and managed. We described how to virtualize and manage WAS installation, deployment strategies and scenarios, the advanced features of Solaris 10 (e.g. SMF, Resource Management, Process Rights, Containers and Zones, ZFS, DTrace), the differences of WAS on Solaris from other platforms (e.g. Sun JDK), how to monitor and tune WAS along with Sun JVM, Solaris, and much more.

I personally would like to thank to all those from both Sun and IBM sides who helped make this project happened as well as those who participated and contributed on the project. I am very appreciative of those reviewers from various Sun and IBM engineering organizations who spent many hours for accuracy and correctness of the content. We tried our best to recognize them in the Preface of the book. If we inadvertently left any of you out, we apologize. I also am thankful for those who sent me great questions and feedback for the book from around the world.

Last but not the least, I must thank my family 'AAAA' for giving me love and support while I was working on the book many weeks and nights away from and at home. Without you, I couldn't have accomplished this. I love you all.

Finally, below are some comments we got so far for the book. Please feel free to send them along, rate it at the Redbook site, or comment here on the blog.

  • "Good informations, we use it a lot", "Excellent Redbook...very informative!"
  • " Good work.", "Great..We have been waiting for."
  • "Excellent", "Very useful, This Redbook is very useful for our Business Partners, because they need the information and technique how to configure/use WebSphere Application Server on Solaris 10 virtualization technology."

So, go download the following and make most use of your Solaris platform -- the best OS on the planet!
