Chapter 8 Use Apple Qmaster to set up a distributed processing system 236
Failure notifications
There are two ways that the Apple Qmaster distributed processing system can provide
information about a problem.
•
Email notification: When a processing service stops unexpectedly, Apple Qmaster sends
a notification 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 files for individual jobs or batches: If a particular job or batch fails, a log file is generated that
describes this failure. You can find the name and location of this log file 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.
