Assume the Election service isimplemented in RMI and must ensure that all votes are safely stored even when the server process crashes. Explain how this can be achieved.
What will be an ideal response?
The state of the server must be recorded in persistent storage so that it can be recovered when the server is restarted. It is essential that every successful vote is recorded in persistent storage before the client request is acknowledged.
A simple method is to serialize the Vector of votes to a file after each vote is cast. A more efficient method would append the serialized votes incrementally to a file. Recovery will consist of de-serializing the file and recreating a new vector.
