Managing Network Time Synchronization

Example of Synchronizing Two Directory Trees

Suppose you have two Directory trees on your network and you want all the

servers in both trees to synchronize to the same time.

You used the default installation, so the Root servers of the trees (ROOT1

and ROOT2) are Single Reference servers, Tree Mode is set to “Yes,” and

Service Advertising is set to “Yes.”

Each Directory tree is synchronized within itself, but time between the

Directory trees differs by a few minutes.

To synchronize both trees, stop the NetWare server process on both servers,

then set the following variables, and restart the servers.

• Server ROOT1:

Set “Time Server Type” to ”reference.”

Set “Time Sources” to ”root2”

• Server ROOT2:

Set “Time Server Type” to ”primary”

Set “Time Sources” to ”root2”

The Root servers of both Directory trees synchronize; this synchronizes all

the other servers in both trees.

Since the Roots are now both time providers, it is necessary to change “Time

Server Type” from “Single” to “Reference” on Server ROOT1 and

“Primary” on Server ROOT2.

Server ROOT1 is a Reference server so that there will be a central point for

controlling time on the network.

When you synchronize two Directory trees, you double the size of the time

synchronization network. You should examine the physical layout of the

network and add other Primary servers, or consider hand-conﬁguring the

time sources and eliminating the use of SAP.
