Why is AMBLIST output required when sending a dump? 

Environment

Release:
Component: ALCMST

Resolution

Any time that you are requested to send a dump, support will also need to receive output from an AMBLIST for the active load module name listed in the symptom dump. This is necessary since the application of PTFs can change the locations of code within a CSECT.

For example, if this was the system abend that is reported:

                       IEA995I SYMPTOM DUMP OUTPUT

                        END OF SYMPTOM DUMP

Support will also need the output from this corresponding job in order to read the dump.
