Abstract: A method for analyzing data corruption is disclosed. In one embodiment, such a method includes identifying a data set to analyze for data corruption. This data set resides on tracks of a volume. The method further determines, from control information associated with the volume, on which tracks of the volume the data set resides. The method reads content of the data set without opening the data set by performing full-track reads of the tracks. The method further determines an expected format of the content by analyzing the control information. An actual format of the content is compared to the expected format to identify areas of the data set that may be corrupt. A corresponding system and computer program product are also disclosed.

Abstract: A method, system and computer readable medium that predict times where cost of catalog caching is not efficient and deactivating catalog caching for that catalog during the predicted times. More specifically, an optimized catalog caching operation conducts historical analysis on catalog usage via records such as resource measurement facility (RMF) records and catalog statistical data.
