When OAM issues message CBR7100I to report a failure (abend), it writes a software error record in SYS1.LOGREC.
Also, when OAM detects a programming failure, it constructs in SYS1.LOGREC a symptom record that contains a description of the failure.
To print these records, use the EREP service aid. For information on EREP, see EREP User's Guide and EREP Reference.
