Albert Leigh's Weblog: Sun IBM WebSphere Solution Architect

I presented the topic on Java SE 6 Performance Features and Update at Austin Java Users Group in December 2009. The slides are available here.

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. This eliminates the need to fine tune "NewSize/MaxNewSize". G1 also provides incremental compaction in those regions by "evacuating" the regions that are full and fragmented...

Solaris is the leading UNIX platform for deploying enterprise WebSphere applications. If you are interested in connecting up with the top engineers for WebSphere On Solaris (IBM WebSphere, Sun JVM, Solaris, SPARC, CMT, etc.), please join this group on LinkedIn.

This is a global networking group open to all professionals (e.g. architects, technologists, engineers, administrators, users, managers, etc.) who work with IBM WebSphere products on Sun's Solaris Operating System. Members may network with each other, discuss and share ideas, techniques, tools, issues, etc. pertaining to deployment, configuration, performance, and management of WebSphere products, Sun JVM, and Solaris.

Here is a great article that was published by the IBM WebSphere Portal Performance team in collaboration with my colleague, Daniel Edwin, of Sun ISV Engineering.

The paper discusses about WebSphere Portal Server v6.1 performance and scalability on Solaris 10 running on the T5240 (Chip Multi-Threading (CMT) based) server and how to configure and deploy a number instances using the Solaris Container technology.

This blog entry contains a "Recap of JavaOne 2009" that I presented at the Austin Java Users Group in June 2009. It also provides the detail listings of the Hands-On Labs and links to download the lab materials.
