    * RECOMMENDATION: Apply the provided PTF.                      *
    ****************************************************************
    Event Exception Processing stores the most recent authorization
    failure events with the corresponding IFCID data in memory. The
    oldest entries will be replaced with data of new events. If the
    Exception Processing User Exit is enabled, references to the
    stored entries are provided to the Exception Processing User
    Exit. Depending on the dispatching of the Event Exception task
    and Exception Processing User Exit driver task and the amount
    of events, an authorization failure event entry might already
    have been overwritten or released by the time it is accessed
    by the Exception Processing User Exit module. Access to the
    outdated data results in Abend S0C4.
    

Problem conclusion

  • The code has been corrected to provide a copy of event data to
    the Exception Processing User Exit driver module. The copy is
    released after the Exception Processing User Exit has completed
    the processing of the event. In case of bursts of excessive
    authorization failure events only the first event of a burst in
    the sample interval is submitted to the Exception User Exit.
