OSF DCE Administration Guide—Core Components
• A clerk requires values from three servers.
• A server requires values from two other servers. Each server uses its own clock
value when computing a new time.
To reset the minservers attribute value, enter the dts modify command with the -change
option to set the desired value. The command accepts values from 1 to 10 . For example,
to increase the required number of servers to 4, issue the following command:
dcecp> dts modify -change {minservers 4}
Although there is no direct relationship between the localservers attribute, which
specifies the number of local servers in a LAN, and the minservers attribute, the
minservers attribute value is usually a subset of all the local servers. To see the current
values of both or either of these attributes, you can use the dts show command. Wait
until the DTS nodes on your LAN are running for at least 10 minutes before you issue
the command. That way, the dts show command is sure to show all of the local servers
in your node’s synchronization list. The dts show command can be entered with options
(-attributes or -all) or without any options, as follows:
dcecp> dts show
{checkinterval +0-01:30:00.000I-----}
{epoch 0}
{tolerance +0-00:10:00.000I-----}

{servergroup subsys/dce/dts-servers}
{status enabled}
{uuid 000013ed-000b-0000-b8ef-03a4fcdf00a4}
In the previous example, the minservers attribute value is set to 4. This setting provides
redundancy; in the case where there are no global servers in the network, the system
synchronizes even if a local server becomes unavailable.
