The RMI server used to allow multiple clients to access RAFo files on a remote server. The RAFoRMIServer is capable of opening multiple RAFo files simultaneously and providing access to these files to multiple clients in a thread safe manner. Thus, only one instance of RAFoRMIServer ever needs to be run on a server to provide access to every RAFo data file on the server to every client on the network.

public void open(java.lang.String dbName)
throws java.rmi.RemoteException,
java.io.IOException,
RAFException
Note: The client does not have direct access to remote method calls.
They are handled automatically by the remote instance obtained
through a call to the RAFo.getRemoteInstance
method.
