Chapter 9: Replication
Adding peers to a new replication ring

Adding peers to
a new replication
ring
The steps for adding machines into a replication ring is described below, in the
order in which they should be done.
1. Verify SafeWord server software is installed
SafeWord server software must be installed on each machine to be added to
the ring. If needed, refer to the “Installing SafeWord 2008” on page 20.
Once all machines have SafeWord server software installed, and all machines
are time sync’d, you can start adding peer machines into the replication ring.
2. Verify time sync on peer machines
To maintain time synchronization, Network Time Protocol (NTP) can be used to
synchronize clocks to Universal Coordinated Time (UTC - the international time
standard). Any computer on your network can get time from NTP servers on
the Internet, and a good source for time synchronization can be found at
http://tycho.usno.navy.mil.
Before adding additional peers to your replication ring, you should ensure that
the target machine’s clock is synchronized to a stable, accurate time source.
1
On the first peer in your replication ring, go to the Windows Time service,
found under
Start > Programs > Administrative Tools > Services
.
2
Scroll down in the list to locate
Windows Time
, and verify that its status is
Started
, and its Startup Type is
Automatic
.
If not, right-click
Windows Time
, select
Properties
, and set the status to
Started
and/or startup type to automatic.
3
Close the Services window.
4
Launch a Command Prompt window, and enter the following command:
c:\net time /setsntp:IP_address
where
IP_address
is the name of the master time source, or IP address (or
fully qualified domain name) of Master server.
5
In the (still open) command prompt window, enter the command:
c:\w32tm -once
This will execute an immediate time sync to the source you listed in step 4.
6
Repeat these procedures for each machine in the ring.
