GlassFish V2 Clustering and Load Balancing - Simplified

Sun GlassFish V2 Enterprise Server is the first fully compliant Java EE 5  Application Server which is Enterprise-Ready, Production-Quality, High Performer available as open source and free for customer deployment. Its Subscription offers flexible and cost-efficient three software-support-levels to match customer needs, Standard, Premium, and Premium-Plus.

Sun Microsystems first announced the Project GlassFish in JavaOne 2005, as an initiative to open source its industry renowned commercial Application Server and the Java EE Reference Implementation. First release was in JavaOne 2006.

The key challenges among Enterprises or Next Generation web delivery companies is the growing user subscription base, requirement for scalability, high availability, a robust backbone, and most critically the cost-effectiveness. Deployment of GlassFish V2 with Sun SPARC Enterprise CoolThread Servers provides a robust infrastructure solution with advanced Application Server features and capabilities.

Presentation : GlassFish-V2-Clustering-Simplified.pdf

The presentation is a sincere effort to simplify the understanding of GlassFish V2 Clustering and Load Balancing concepts, architecture, implementation and deployment configurations. The technical content has been tested for accuracy and reliability on multiple platforms. The presentation provides both the perspectives, technical and business advantages in adopting GlassFish technology. 

Sun GlassFish Enterprise Server V2 can take real advantage of State-Of-The-Art CoolThread Server technology for high performance throughput computing and scalability.

It has set a world record, at the SPECjAppServer2004, as the fastest open source application server on Sun Fire T2000, delivering 883.66 JOPS@Standard, which is faster than Websphere 6.1 by 30%, and WebLogic by 10%.

Sun SPARC Enterprise T5440, the latest CoolThread Server is eco-efficient and provides the reliability of mid-range systems.

Comments:

Satya,

This is jrobey from thread ID 53958 in the glassfish discussion forum. I would be interested in a voice and webcast cluster demo--particularly concerning session and session bean state replication and in timer operation across a cluster. My timezone is USA MST, but I can be up when needed. I'd be super happy with something during the workday over here.

You mentioned in your last comment that if a node goes down that I should see session data replicate over. I was under the impression that the replication data transferred in real time to another member of the cluster (not really sure how the ring is determined/controlled). What I am hoping to do is to tell my load balancer to ignore sessions and cookies and just pass to any instance in the cluster. My understanding was that this was the model that memory-replication was going for.

Regardless, I think I have everything setup according to your slide show, but am still coming up short. I might try a reinstall (again) just working off your slide show to see where I get. Is there a good way to turn on debugging statements for the memory-replication feature? I'd love to get any idea as to whether it is trying to do something or not. Thanks for the time and responses.

Jason
