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

Claim 9:
10. A non-transitory computer readable medium for use in restoring data processing capabilities in the event of an interruption, comprising:
a user catalog program embodied in the medium, that when executed by a processor configures the system to store indexes of data utilized by the system;
a system management facility (SMF) program embodied in the medium, that when executed by the processor configures the system to create SMF audit records that track the catalog activity as SMF data; and
a virtual catalog program embodied in the medium, 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.
