Configuring And Administering Time Synchronization - Novell OPEN ENTERPRISE SERVER - PLANNING AND IMPLEMENTATION GUIDE 12-2010 Implementation Manual

Existing Tree
When a server joins an existing eDirectory tree, both OES installations do approximately the same
thing.

OES 2
If you are installing into an existing tree, the OES 2 install proposes to use the IP address of the
eDirectory server (either NetWare or Linux) as the NTP time source. This default should be
sufficient unless one of the following is true:

The server referenced is a NetWare 5.0 or earlier server, in which case you need to identify and
specify the address of another server in the tree that is running either a later version of NetWare
or OES 2.

You will have more than 30 servers in your tree, in which case you need to configure the server
to fit in to your planned time synchronization hierarchy. For more information, see
Time Synchronization Hierarchy before Installing OES" on page
The OES 2 install activates the xntp daemon and configures it to synchronize server time with the
specified NTP time source. After the install finishes, you can configure the daemon to work with
additional time sources to ensure fault tolerance. For more information, see
Synchronization Settings on a SLES 10 Server" on page
NetWare 6.5 SP8
If you are installing into an existing tree, the NetWare 6.5 SP8 install first checks to see whether you
manually configured either NTP or Timesync time synchronization sources while setting the server
Time Zone (see "Setting the Server Time Zone and Time Synchronization
SP8: Installation Guide).
If you will have more than 30 servers in your tree, you should have developed a time
synchronization plan (see
page 105) and used the Time Zone panel to configure your server according to the plan.
If you haven't manually configured time synchronization sources for the server (for example, if your
tree has fewer than 30 servers), the install automatically configures the Timesync NLM to point to
the IP address of the server with a master replica of the tree's [ROOT] partition.

12.3.5 Configuring and Administering Time Synchronization

As your network changes, you will probably need to adjust the time synchronization settings on
your servers.
