The Data Server manages data coming from various feeds, provides live updates of data
values when requested and distributes the data out to the appropriate recipients.
Enabling the

ONTROL
THE

S
ERVER
setting ensures the Data Server remains paired
with the Xmedia Server at all times in a replication environment. The objective in the
replication environment is to keep the server’s two components, the XMS and the Data
Server, together. As a result of enabling this setting, the Xmedia Server becomes the
master server to a Data Server and therefore is replicated as well.
Figure

demonstrates that once the

following changes are applied to the Data Server Control Panel’s

•
The upper panel displays the following message:
