newServerConfiguration

public static ServerConfiguration newServerConfiguration()

creates a new ServerConfiguration

openServer

public static ObjectServer openServer(ServerConfiguration config,
                                      java.lang.String databaseFileName,
                                      int port)

opens an ObjectServer on the specified database file and port.

Parameters:

config - a custom ServerConfiguration instance to be obtained via newServerConfiguration()

databaseFileName - an absolute or relative path to the database file

port - the port to be used or 0 if the server should not open a port, specify a value < 0 if an arbitrary free port should be chosen - see ExtObjectServer.port().

Returns:

an ObjectServer listening on the specified port.

Throws:

Db4oIOException - I/O operation failed or was unexpectedly interrupted.

DatabaseFileLockedException - the required database file is locked by another process.

IncompatibleFileFormatException - runtime

OldFormatException - open operation failed because the database file is in old format and Configuration.allowVersionUpdates(boolean) is set to false.

DatabaseReadOnlyException - database was configured as read-only.
