More on clustering and load-balancing in GlassFish v2

Cluster image

One of the key features in GlassFish v2 is clustering support. With greater power comes greater responsibility, so Prashanth has a detailed post on setting up and using the clustering, load-balancing and data replication features from the newly released GlassFish v2.

Prashanth goes into the various options in terms of replication and load-balancing using either software (web servers) or hardware solutions. It also covers more advanced topics such as establishing a secure connection between the DAS (Domain Admin Server) and the web server. Shreedhar comments with interesting GMS/Shoal prerequisites like syncing machine clocks.

Update: The clustering features briefly described here are meant to give readers a feel for how this all works and is not intended to replace the product documentation

•  Sun Java System Application Server 9.1 Deployment Planning Guide
•  Sun Java System Application Server 9.1 HADB Commands Reference Manual.


hi there,

"With greater power comes greater responsibility,"

and that responsibility cannot be easily washed off by a blog post. You need cohesive documentation (example BEA's Weblogic docs) where documentation for all the production versions are available long after they were released(for each version).

It's going to take Glassfish community a lot of hard work to become the #5 Appserver

To my recokoning, the top 5 appservers are (not necessarily in that order)

1) Weblogic
2) WebSphere
3) Oracle
4) Tomcat
5) JBoss

Humm. Are you asking for better documentation? If so, I agree, and saying that the documentation is there is not a good excuse, we have to make it easier for you to find it. Stay tuned and check as we work on this.

But if you are going to rank AppServers (and want to start a conversation about it) you need to give some hint at what metric you are using... Do you mean adoption? Performance? Standards? Downloads? Contributors? Revenue? Enterprise or Development? ...

I've updated the entry to reflect its real intent (which is not to replace documentation).
