Monitoring Propagation Queue Files
When database changes occur on the primary server, the modifications
are recorded in the propagation queue file, prop_q. The kpropd daemon
reads the prop_q file, which lists all principals that have changed since
the last propagation cycle. At the end of a successful propagation cycle,
all security servers have up-to-date principal databases.
To indicate successful propagation, kpropd creates a prop_hostname_ok
file, a zero-length file, where the hostname is the name of the security
server being propagated to. If the propagation failed, a prop_hostname
file is created and all the un-propagated changes are saved to the file.
After propagation of these changes to all of the secondary servers
succeeds, the contents of the queue file, prop_hostname, are deleted. If
neither the prop_hostname or the prop_hostname_ok file exists for a
specific host, then kpropd conducts a full dump of the primary database
to the secondary server that is missing a queue file.
Monitoring for Old File Date and Large File Size
In rare cases, a propagation failure or stall may occur without any
indication of error in the syslog messages. Additional monitoring
measures can be taken to check for proper operation of the propagation
system. The propagation queue files can be monitored for unusual
characteristics, such as old file creation date or large file size. Under
normal conditions these files are created, deleted, and appended many
