Software records are recorded on the LOGREC data set for any of
the following conditions:
- Hardware-detected hardware errors, such as software recovery attempts
for hard machine failures
- Hardware-detected software errors, such as program checks
- Operator-detected errors, such as pressing the restart key
- Software-detected software errors that are detected when:
- The CALLRTM TYPE=ABTERM macro or the ABEND macro was started.
- A non-abend error occurred and the detecting program invoked the
symptom record reporting facility.
- An abend occurred and a recovery routine requested that RTM record
a system diagnostic work area (SDWA).
- A program issued an incorrect SVC
- There was an excessive spin condition.
- Records for hardware-detected or software-detected errors that
were lost because they cannot be written to the LOGREC data set
The types of software records are as follows:
- SDWA record
- Lost record summary record
- Symptom record
- Excessive spin processor list.
