A database processing system includes a coordinator agent controller and a virtual node data base. The coordinator agent controller detects a request to access a database by an application program and to extracts database objects from a database protocol stream based on a requirement requested by the application program. The virtual node database is generated according to the extracted database objects. The virtual node database includes memory dump storage that stores the database objects extracted from the database protocol stream, and based on the database objects the virtual node database generates virtual database objects corresponding to the database protocol stream. The extraction of database objects is performed directly on the database protocol stream without communicating with a target real database.
