Verfahren zur Sicherstellung der Kompatibilität und Verfahren zur Datensicherung innerhalb eines mehrere Teilrechnersysteme aufweisenden verteilten Rechnersystems

摘要

The invention relates to a method for assuring compatibility between the software units activated in partial computer systems (system A, system B) belonging to a distributed computer system, said software units each comprising their respective version of software codes and/or data. Once a compatibility test has established compatibility, a compatible non-activated software unit is activated on its partial computer system and the corresponding previously activated software unit is deactivated. The invention also relates to a method for securing data within a distributed computer system with several partial computer systems. According to this method, the securing of the data is synchronised and steps for securing the data belonging to the respective partial systems, for blocking access to the data, for securing common data and for deactivating the data access block are carried out according to the current status of the data securing operation.
