All workstations (clients) connect to the file server through cables plugged into network interface cards at each location. Each client workstation has software installed to allow you to connect to the VT server. All of your broadcast information is stored on the server in the database. That means if your workstation should stop working, everyone else can continue working as usual. If the file server stops working, everything grinds to a halt until it is fixed or replaced.
If only one workstation is necessary, it is possible to have one computer perform the function of both (file) server and client (workstation). It is possible to add additional workstations (clients) to a server/client combination unit but in cases where you have multiple workstations, VT runs much more efficiently when the server is not also busy with client processes. We suggest a dedicated server for multiple workstation setups.
Normally, the file server remains turned on and "runs" all the time. Each workstation can be turned off when it is not necessary to access VT. In fact, we recommend you exit VT anytime you know you will be away from your workstation for some period of time such as lunch. If you do not exit VT, at the very least always return to the front menu screen before walking away to do something else. If you are somewhere "inside" a VT application and then walk away or go home, it is possible some functions can not be completed until you exit.
The server is a partner in any VT operation and actually performs processing "work" for certain operations where it is not practical to use the individual workstations. A VT server does more than route the files back and forth from the workstations to the server.
Although the VT server functions are an integral part of VT, you normally do not run the VT application from the server as you do on a workstation. It is possible, but this causes the server to perform client activities as well as server functions and performance is degraded. The server provides support functions for the workstations.
The VT Scheduler schedules all spots (except for fillers) and is located on the server. You can view scheduler activity from a workstation through the VT Scheduler Message Queue under the System Information menu.
The VT System Processor is another module located on the server that takes care of many background functions not handled by the scheduler. Do not presume that VT is not doing anything because no one is working on a workstation.
We are not trying to make you Windows server experts. We do want to make sure you know about the few functions that must be performed normally at the server. These functions are not available from the client workstations.
