Chapter 5: New Features in EAServer Versions 4.2.3, 4.2.2, 4.2.1, and 4.2

New features in version 4.2

This section outlines the new features in EAServer 4.2.

In-memory HTTP session replication

For Web applications that are deployed in an EAServer cluster, EAServer 4.2 can distribute HTTP session data using in-memory replication rather than database storage. This feature can improve performance by avoiding the overhead of writing to the database. For more information, see “Deploying Web applications to a cluster” in Chapter 7, “Load Balancing, Failover, and Component Availability,” in the EAServer System Administration Guide.

Pooled component destruction

EAServer 4.2 explicitly destroys pooled component instances before the server shuts down. This allows you to perform cleanup operations in your component, such as closing database connections. For more information, see “Pooled component destruction” in Chapter 2, “Server Tuning,” in the EAServer Performance and Tuning Guide.
