I reiterate this on slide 12 of this presentation: https://secure-web.cisco.com/15OJFhXZDjMhrQH_mFHa_s-M5l5D_KNgHnn34lYPQr2DLLw39aC-U8HA4M9HnDTWZyAINKRf4RF-ED2GMLttRFL2LoKo0--faVnohK9ntpwRffttftzWF1O2Xyb41Tj_LrcU84hJK8qtfDb9h34LCijAbH9G9X-Vid_-2gE3fdYYiQ-1eTd0JZhbTd7OmAjNb2NvZl5kh3Hbd9lWkd_Yd4mi6op2YbI7sp_U_KXuO9AV-oA24o4AQ3b52X4yUstf2BsSNER4GETGFJQG9fNQFoCzhOPCGly8oWC7UzAv6ZRR54Z3Cw1uOzrdjx9f-4cVArpbeGfQPzM6COtRLJPhykSHcqI3SgVWKPvRCap9pxw3fuLyoPfMzsEWHwUHC4VtFyoyn69oiRS_xpfRDfOPev3xM_3LNvv1_nSztEkl_KBFf7Z7xfHODpR_FHnL6rsG4/https%3A%2F%2Fphoenixsoftware.com%2Fftp%2Fdemo%2FThe%2520MVS%2520System%2520Trace.pdf I search from the top for the word "before" and then look from that point in the trace for "RCVY" -- or just an asterisk ("*") if "RCVY" not found -- as part of my root cause analysis. ~95% of the time, I see in the trace exactly what I expect to see based on the problem description. The other ~5% of the time I see something unexpected that provides unique insight. I don't know if my approach is a common or prevailing one, but it has served me well in recent years... -- Phoenix Software International Edward E.
