Installing CardioVisions Network Edition

If you wish to access CardioVisions functions from several workstations in a computer

network, you have to install CardioVisions Network Edition. The installation procedure

looks quite similar to that of the Personal Edition (see above), but the result is quite

different. While Personal Edition setup installs a typical program where you have a single

executable file to start and then you can access all functions, the Network Edition setup will

install two separate applications, two executable files: one for the networked CardioVisions

database engine application (also called the database server), and another for the so-called

CardioVisions client application, i.e., the user-end of the program to ask for data over the

network from the database engine on any workstation. Therefore, the Network Edition has

to be installed on a properly configured server computer. After the installation, the

CardioVisions database engine will be automatically started by default whenever the server

computer is started. The Network Edition has to be installed on the server computer, on the

individual workstations only a shortcut has to be created. Then, as a result, the database

engine will run on the server computer continuously, and the CardioVisions client can be

started on any workstation with a proper shortcut (startup icon). For all normal user

purposes, the CardioVisions client of the Network Edition is indistinguishable from the

program used in the Personal Edition. There is one important difference in behaviour,

however: if you use the Network Edition and the server computer is shut down, it will not be

possible to start CardioVisions from the workstations. Similarly, even if the server computer

is switched on, but the CardioVisions database engine is not running (it is stopped, shut

down or not started at all), it will be impossible to use CardioVisions.

Compared to the installation of CardioVisions Personal Edition, there is one additional step

to take during the installation of the Network Edition. After you have choosen the recorder

type(s) to use, you are asked to select an IP-address (a network property) through which the

database engine can communicate with the client(s) running on any workstation. This is a

question only if the server has multiple network adaptors, either for intra- or extranet

purposes, or because of different physical subnets.

To complete your CardioVisions Network Edition installation, you have to manually share

the “CLIENT” folder of your installation with read-only access from all workstations and

you have to create a shortcut on each workstation pointing to the CardioVisions client

application executable file in this folder (its name is CV001.EXE). This is best done manually

as automatic sharing is either impossible or can have serious security risks, and once the

shortcut is created, you can simply “copy-paste” it to all workstations where you want to use

CardioVisions. If you have any doubt, consult your computer network administrator.

It is possible to configure your own CardioVisions database engine application to use

different options in the unlikely case of networking problems. Since database engine is an

auto-configuring application, change a working configuration only if it is absolutely necessary

and always with the close assistance of an experienced network specialist. To change

database engine configuration, first request all users to log out from CardioVisions and close

all CardioVisions clients on all workstations, then bring up the database engine application

from the system tray on the server computer by double-clicking its icon, then choose Server

– Stop, then select the required command of the Config menu. After your changes, choose

Server – Start to make the CardioVisions database engine services available to users again.
