Responding to Software Failure Reports
1. Takes the dump and copies the dump file and various other files to a
subvolume for further analysis by the support organization. (For more
information, see Files Included in Failure Data Collection on page 1-7.)
2. Records the failure signature as a new incident record in the incident
database.
3. Sends a software failure event to the Event Management Service.
b. If the failure is redundant (a rediscovery of a previous incident), the TFDS
monitor:
1. Records a rediscovery incident in the incident database.
2. Sends a software failure event to the Event Management Service
indicating that the failure is a rediscovery.
3. Reloads the affected processor.
Responding to Software Failure Reports
When a software failure instrument is encountered, the TFDS helper running in the
same processor as the software collects failure data and then sends the data in a
message to the TFDS monitor. The TFDS monitor then performs rediscovery analysis
on the reported failure.
If the failure is unique, the TFDS monitor:
1. Collects additional failure data about the process. (For more information, see Files
Included in Failure Data Collection on page 1-7.)
2. Records the failure signature as a new incident record in the incident database.
3. Sends a software failure event to the Event Management Service.
If the failure is a recurrence of a previous incident (a rediscovery), the TFDS monitor:
1. Might collect additional failure data about the process. (For more information, see
Files Included in Failure Data Collection on page 1-7.)
2. Records a rediscovery incident in the incident database.
3. Sends a software failure event to the Event Management Service indicating that
the failure is a rediscovery.
Note. If the TFDS monitor is not running when the software failure instrument is
encountered, the TFDS helper sends a software failure event to the Event
Management Service, but rediscovery analysis is not performed.
