Setting the time tolerance value
The time tolerance value is a global variable that defines the number of
seconds that one 3-DNS Controller's time setting is allowed to be out of
sync with another 3-DNS Controller's time setting. We recommend that you
leave the time tolerance variable at the default setting of
10
.
To check the value for the time tolerance setting using the
Configuration utility
1. In the navigation pane, click
System
.
The System - General screen opens.
2. On the toolbar, click
Timers and Task Intervals
.
3. Note the value in the
3-DNS Sync Time Tolerance
box, and change
it if necessary.
4. If you change this setting, click
Update
to save it. For more
information about the settings on this screen, click
Help
on the
toolbar.
To check the value for the time tolerance setting in the
configuration file
1. To ensure that the configuration files contain the same information
as the memory cache, type the following command:
3ndc dumpdb
2. Open the
wideip.conf
file in a text editor (either
vi
or
pico
).
3. Search for
time_tolerance
. If the
time_tolerance
sub-statement is
not in the configuration file, the default (
10
) is used.
