Failure notications
There are two ways that the Apple Qmaster distributed processing system can provide
information about a problem.
•
Email notication: When a processing service stops unexpectedly, Apple Qmaster sends
a notication email to the address that was entered in the Apple Qadministrator Cluster
Preferences dialog for that cluster. If no address was entered there, the email is sent to the
address in the Internet settings of the computer on which the cluster controller is enabled.
Note: Apple Qmaster does not support SMTP servers that require authentication.
•
Log les for individual jobs or batches: If a particular job or batch fails, a log le is generated that
describes this failure. You can nd the name and location of this log le in Share Monitor by
selecting the batch or job, clicking the Show Info button, and clicking the Show Log button.
For more information, see Share Monitor Help.
