Abstract
A method, system and computer-usable medium are disclosed for optimizing a Partitioned Data Set Extended (PDSE) directory. In various embodiments, b-tree directory structure entries associated with members of the PDSE are reordered to place members with the highest access counts within the same leaf nodes. This allows these members to share a directory path, which in turn increases the chance that the most frequently accessed member's directory path is in cache while minimizing storage footprint.
