The DB_ENV->set_server method has been deprecated and replaced with the DB_ENV->set_rpc_server() method. The DB_ENV->set_server method will be removed in a future release, and so applications using it should convert. The DB_ENV->set_server method can be easily converted to the DB_ENV->set_rpc_server() method by changing the name, and specifying a NULL for the added argument, second in the argument list.
