A high incidence of production program abends could indicate inadequate testing procedures. You can use the Program History Search display to determine if production jobs are ending abnormally. You should also review the operator shift log for the given time frame to determine if the problems are being followed up. If important production programs do not appear on the display, check the operator shift logs to find the reason.
Remember, the Program History Search display requires that the SMF record types indicated above are being recorded. If any of these records are missing, your display is not complete. Because SMF recording can be turned on and off, do not jump to conclusions about the information provided in the display. You should check the SMF Options Display (1.5.1) to determine if the correct SMF record types are being recorded. You should also check the SMF Exits display to determine if the IEFU83 and IEFU84 SMF exits can cancel SMF records.
See SMF in the “Management Information” chapter for more information on the SMF options and exits in effect on your system. Also see System Review Checklist for specific tests you can perform to verify the integrity of the SMF records.
