IIRC, the system dump data sets should not be deleted. Dynamic dumps require SMS to be active. Before SMS is active, no dump can be taken when the old-style dump data sets are not available anymore. I remember one occasion where MSTJCL failed to start. The system did not go into a wait state, but it did not come up, either. Without that old-style dump I would never have found the problem - accidentally ISPF compress was used on the parmlib member. That resulted in a lot of gibberish, but no comprehendable JCL statements. Worst, when you checked mstjclxx via ISPF, it looked completely okay. Better keep your old-style dump data sets to be used until SMS is fully active.
