The EJB Container Availability tab of the Availability Service enables you to change these settings:
HA Persistence Type: Specifies the session persistence and passivation mechanism for SFSBs that have availability enabled. Allowed values are file (the file system) and ha (HADB). For production environments that require session persistence, use ha, the default.
SFSB Persistence Type: Specifies the passivation mechanism for SFSBs that do not have availability enabled. Allowed values are file (the default) and ha.
If either Persistence Type is set to file, the EJB container specifies the file system location where the passivated session bean state is stored. Checkpointing to the file system is useful for testing but is not for production environments. For more information, see To configure the store properties in Sun Java System Application Server Enterprise Edition 8.1 2005Q2 Administration Guide.
HA persistence enables a cluster of server instances to recover the SFSB state if any server instance fails. HADB is also used as the passivation and activation store. Use this option in a production environment that requires SFSB state persistence. For more information, see configure-ha-cluster(1).
SFSB Store Pool Name: You can change the SFSB Store Pool Name if you changed the JDBC resource used for connections to the HADB for session persistence. For details, see configure-ha-cluster(1).
