GlassFish v2.1.1 and Sailfin 2.0 (Sun GlassFish Communications Server 2.0 ) released!
By Shreedhar Ganapathy on Oct 28, 2009
GlassFish v2.1.1 has over 200 bug fixes and improvements. On the high availability side, we have refined the replication module further and on the fault tolerance side, Shoal GMS Clustering (version 1.1) now leverages the GlassFish Node Agent's ability to detect process losses quickly to inform Shoal GMS Members about failures. This improved our software failure detection timeout from around 9-12 seconds to around 4-5 seconds - an important improvement in supporting failover and other recovery oriented computing components.
Sailfin 2.0 introduces High Availability for SIP and Converged applications and uses an enhanced predictive replication algorithm supporting high traffic and large number of active sessions in addition to supporting Rolling Upgrade with session states retained. With many improvements in Shoal's clustering core along with support network traffic specification to specific network interfaces, and improved health state transitions, this makes for added reliability and scalability in the clustering capabilities of Sailfin.
Congratulations to the entire Sailfin and GlassFish developer community for splendid work in successfully releasing these products.
