EAServer 4.2.2 introduces a new mechanism to support passivation of EJB stateful session beans based on the instance timeout property. Passivation is the process of removing an instance’s data from memory and saving it to a database. Passivation allows the server to free the memory used by an instance while keeping the instance available for use by the client. When the client calls the component again, the instance is restored to memory. For more information, see “Using EJB activation and passivation” in Chapter 28, “Configuring Persistence for Stateful Session Components,” in the EAServer Programmer’s Guide.
