Assignee: TERACLOUD APS
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A system for use in restoring data processing capabilities in the event of an interruption, comprising:
a processor;
a storage device accessible by the processor;
a user catalog program that when executed by the processor configures the system to store indexes of data utilized by the system;
a system management facility (SMF) program that when executed by the processor configures the system to create SMF audit records that track user catalog activity as SMF data; and
a virtual catalog program that when executed by the processor configures the system to:
intercept portions of the SMF data over a timeline, the portions corresponding to the creation, deletion, and modification of the data files, and catalog the intercepted portions of SMF data over the timeline in a virtual catalog;
wherein the data utilized by the system includes a dataset; and additional event data related to use of that dataset, after an interruption is detected;
the processor restores data processing capabilities of the system based on a combination of the stored indexes from the user catalog program and the intercepted portions of SMF data from the virtual catalog program; and
a respective catalog activity record of the user catalog activity accounting for a location of the dataset that was deleted and/or altered prior to the interruption is absent from a respective stored index of the stored indexes but information about the dataset that was deleted and/or altered is present in the virtual catalog.
