Stateful session beans failover settings (EJB modules)
Each EJB container provides a method for stateful session beans to fail over to other servers. Use this method to specify whether failover occurs for the stateful session beans in this module. We can also override the stateful session bean replication settings of the parent object for this module.
From the admin console, click...
Applications > Application Types > WebSphere enterprise applications > application_name. Under Modules, click Manage Modules. Then click the jar name. Under Additional Properties, click Stateful session bean failover settings.
Enable stateful session bean failover using memory to memory replication
Specifies whether the EJB container attempts failover for all of the stateful session beans in this module.
This check box overrides the default stateful session bean failover setting that the administrator configured for an EJB container or the application module application. Clearing this check box disables failover for this module.
Use application or EJB container replication settings
That the replication settings configured for the EJB container or application are used for this module. If we select this option and we want the application to use stateful session bean failover, define memory to memory replication for the EJB container on each server we want to use failover.
Use module replication settings
That the replication settings configured for this EJB module are used for memory-to-memory replication of the stateful session bean data.
If we select this button, we override the replication settings for the EJB container and application. This button is disabled until we define a replication domain. This selection has a hyperlink to help we configure the replication settings. If no replication domains are configured, when you click the link, then you visit a page where we can create one. If at least one domain is configured, when you click the link, then you visit a page where we can select the replication settings to be used by the EJB container.
