Large Networks
A Large Network Database System is the interconnection of up to 10 M3154 Database Server
systems. When installing and configuring a Large Network system, keep the following in

Software Installation & Configuration
All M3154 Database Servers and their connected Information Centers and Clients must
be running the same revision of Information Center software.
In a large network system, combining E.0 and E.01 M3154 Database Server systems is
supported.
One of the M3154 Database Servers must be designated as the "Master Server". The
master server is responsible for maintaining the list of other servers in its database and
also provides for the addition/deletion/changing of additional servers during
monitoring.
In a mixed E.0/E.01 large network system, the Master Database Server must be running
E.01.
The Master Database Server must be installed and configured first.
The remaining M3154 Database Servers (non-masters) must enter in the Master
Server's name in the Purchased Options and Support Information window. If the non-
masters are not registered with the Master Database Server, they cannot receive or send
patient data outside of its domain.
If a Master Database Server adds a non-master server to its list, verify that the non-
master does not already have a Master Database Server associated with it. If the non-
master has another Master Database Server name configured, it will not accept the new
Master Database Server.
The Master Database Server behaves as the external time source for all non-master
servers. If an external time source (source other than the Master Database Server) is
configured, all connected Information Centers and Clients have the Date/Time
configuration window disabled. The Database Server's is enabled, but it is overridden
by the external time source. If there is no external time source configured, only the
Master Database Server's domain has the Date/Time application enabled.
The Master Database Server list is part of the archive/restore for the Master Database
Server and all the non-masters.
In a large network system, when restoring archive files, verify the archive is for the
correct Database Server. If a Master Database Server archive is restored on a non-
master Database Server, an invalid configuration is introduced (two Database Servers
cannot be set to master).
When Web Access/Large Network system option is enabled, and a new Master/non-
master relationship is configured, note that all the clinician data (user names and
passwords) on the non-master server will be lost. These must be re-entered using the
"Web User Access Config Tool" on page B-6.
If the Master Database Server is offline, the non-master Database Servers cannot view
the review applications using Information Center Web, since the Master Database
