ABSTRACT:
A method, system, and computer program product for prioritizing directory scans in cache by a processor is provided. While traversing a directory in the cache, one of attempting to acquire a lock for a directory entry and attempting to acquire access to a track in the directory entry is performed. If one of the lock is not obtained for the directory entry and the access to the track in the directory entry is not obtained, the directory entry is added to a reserved data space. Following completion of traversing the directory, a return is made to the reserved data space to process the directory entry and the track in the directory entry.
