摘要: A data processing system includes both volatile and nonvolatile memories, user-inaccessible file control software performs a method for recovering from malfunction occurring during transaction that prevents accomplished microscopic transactions being lost. The comprises the steps of: providing log to maintain record of which may span memories; recording in portion memory, old new images result transaction; writing is contained with image written after it certain present memory; event malfunction, employing memory determine status rolling back occurred prior its completion, further assuring all actions have actually marked as completed.
