Use the following functions to improve the system reliability with respect to availability (stable operations) and fault tolerance (disaster tolerance):
- Session failover functionality
This function is valid for a system that executes a Web application.
You can improve the availability/fault tolerance with redundancy execution by storing the session information in a database or an EADs server, and by inheriting the session information when an error occurs. For details on this function, see the Application Server Expansion Guide.
- Function to deter full garbage collection (Explicit management heap function)
You can deter the full garbage collection by storing the object that is the cause of full garbage collection in a unique area other than the Java heap, and thus improve the availability. Details on this function are described in the Application Server Expansion Guide.
- Function for fault tolerance in the resource connection and the transaction management
You can improve the fault tolerance by detecting an error in the connection, retrying to obtain the connection, and by automatically closing the connection. Details on this function are described in the Application Server Common Container Functionality Guide.
To improve the system reliability by using functions other than those mentioned above, check the description of Relation of System Objectives and Functions in the manuals starting with the Application Server Functionality Guide and use the functions relevant to Reliability.
