    摘要: A recovery mechanism restarts jobs following correction of a system failure and automatically marks the jobs for interruption at a logical boundary. The logical boundary is above logical file updating functions such that logical files are in a known state when jobs reach the boundary. When a system failure is detected which has not yet resulted in lost data, an image of working memory, including hardware status is saved on nonvolatile storage. After the failure has been resolved, the system is initially loaded with operating programs (IPL) and working memory is reloaded from the nonvolatile storage. All jobs which were reloaded are marked for interrupt at a machine instruction boundary, and processing is started. After all jobs have reached the boundary, or a predetermined time has elapsed, processing is stopped and the system is re-IPLed. There are few system index recoveries to be performed, since most jobs reached a point where logical files were synchronized with corresponding data.

    摘要: in einem Datenverarbeitungssystem mit in Seiten unterteiltem virtuellem Speicher werden Datenseiten zwischen Hauptspeicher und Sekundärspeichern ausgetauscht. Der Austausch geschieht auf Grund der Benützung der Seiten. Häufig benützte Seiten werden im Hauptspeicher festgehalten. Zudem können Eingangs-/Ausgangsgeräte verlangen, dass bestimmte Seiten festgehalten werden. Dazu umfasst der Adressumsetzer, der virtuelle Adressen in Hauptspeicheradressen umwandelt, ein Seitenverzeichnis (24). das ein Feld zur Angabe der Seitenbenützung aufweist. Sowohl die zentrale Recheneinheit als auch die Eingangs-/Ausgangseinheiten können veranlassen, wie dieses Feld beschrieben wird.
