I'd propose several stages
  • Change the data set name on the existing output data set, so if some as yet unknown task attempts to use the current data set it can be detected and fixed.
  • Scan SMF 14s and 15s, or perhaps just 14s, for use of the current data set. This can extend back as far as convenient. Collecting data set names in these records is simple as they are at a fixed position in the records.
  • If there has not been any detected problems from the first bullet go with the DD DUMMY idea.
  • If no issues have been detected look at removing the code that creates the data set.
