To define a sync group using the Configuration utility

1. In the navigation pane, click 3-DNS Sync.
The System - Add a New Sync Group screen opens.
2. In the New Sync Group Name box, type the name of the new sync
group and click Add.
The Add a 3-DNS to a Sync Group screen opens.
3. From the list of 3-DNS Controllers, first select the 3-DNS
Controller that you want to be the principal system. Then check the
box next to each 3-DNS Controller that you want to add to the sync
group.
4. Click Add.
Note
For details on how to configure a sync group from the command line, refer
to Appendix A, 3-DNS Configuration File, in the 3-DNS Reference Guide.
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.
