How the smMix Utility Works
DHCTs need active EMMs to receive secured services. DHCTs that have EMMs will
time-out if the EMMs have expired. The camAuditor process of the DNCS examines
the expiration times of EMMs and regenerates those EMMs that are set to expire in
fewer than 20 days. The newly regenerated EMMs are configured so that they expire
in 30 days. Healthy systems therefore have EMMs that are scheduled to expire from
20 days to 30 days in the future.

DHCT Distribution in a Healthy System
Examine the following smMix output from a healthy system. The output depicts
both the chart and the histogram representing EMM distribution times. Notice how
all DHCTs have EMM expiration times from 20 days to 29 days in the future.

all DHCTs have EMM expiration times from 20 days to 29 days in the future.
Notes:
You will notice that a few DHCTs have EMMs with expiration times greater than
29 days. An examination of these records would show that these EMMs actually
expire a few hours into the 30th day.

The data in the following example comes from running the smMix utility in
default mode, with no options.

Based on the distribution of DHCTs in the following example, the system operator
can conclude that the camAuditor process is operating normally and regenerating
EMMs as they age.
