Reconstruction of system definitional and state information
First Claim
1. A system, comprising:
- a memory; and
a processor programmed to;
determine that one of a system definition file data set and a catalog data set is unavailable for orderly restart of an information system, where the system definition file data set provides system resource definition information and the catalog data set provides system resource state information for the information system;
determine that the other of the system definition file data set and the catalog data set is available; and
reconstruct within the memory the unavailable one of the system definition file data set and the catalog data set by rebuilding the system resource definition and state information used by the unavailable one of the system definition file data set and the catalog data set using system resource information within the other available one of the system definition file data set and the catalog data set, comprising the processor being programmed to;
reconstruct the system definition file data set in response to determining that the catalog data set is available, comprising;
parsing the catalog data set;
extracting records related to the system resource definition and state information from the parsed catalog data set;
defining a new instance of the system definition file data set; and
reconstructing the content of the unavailable system definition file data set within the new instance of the system definition file data set using the records related to the system resource definition and state information extracted from the parsed catalog data set.

Abstract
A determination is made as to whether one of a system definition file data set and a catalog data set is unavailable for orderly restart of an information system. The system definition file data set provides resource definition information for the information system and the catalog data set provides resource state information for the information system. A determination is made that the other of the system definition file data set and the catalog data set is available. The unavailable one of the system definition file data set and the catalog data set is reconstructed by rebuilding the system resource definition and state information used by the unavailable one of the system definition file data set and the catalog data set using system resource information within the other available one of the system definition file data set and the catalog data set.

6. A computer program product, comprising:
a computer readable storage memory having computer readable program code embodied therewith, where the computer readable program code when executed on a computer causes the computer to; determine that one of a system definition file data set and a catalog data set is unavailable for orderly restart of an information system, where the system definition file data set provides system resource definition information and the catalog data set provides system resource state information for the information system; determine that the other of the system definition file data set and the catalog data set is available; and reconstruct the unavailable one of the system definition file data set and the catalog data set by rebuilding the system resource definition and state information used by the unavailable one of the system definition file data set and the catalog data set using system resource information within the other available one of the system definition file data set and the catalog data set, where the computer readable program code when executed on the computer causes the computer to; reconstruct the system definition file data set in response to determining that the catalog data set is available, comprising; parsing the catalog data set; extracting records related to the system resource definition and state information from the parsed catalog data set; defining a new instance of the system definition file data set; and reconstructing the content of the unavailable system definition file data set within the new instance of the system definition file data set using the records related to the system resource definition and state information extracted from the parsed catalog data set. - View Dependent Claims (7, 8, 9, 10)
