NexusDB Server is very straightforward to install and configure.
Copy nxServer.exe to the folder on the machine where you intend to store your NexusDB data.
Start NexusDB Server from the machine which will act as the server. This machine must not be a Windows 98 or ME machine, and should have at least 128MB of memory (more is always better).
Click on Aliases. At the bottom, enter an alias name "VSys One" then the path to where your data is stored.
Click on Add to save the new alias and its path, so that NexusDB knows where to look for files when a copy of VSys One asks for it.
Click on the plus sign next to Transports, then on TCP/IPv4 Transport. Check the Active checkbox in the upper-left corner.
Click on GUI Settings, then check the boxes Minimize Server on application start, Bring up Server on application start, Autosave configuration on exit and Close Server from Tray only. Click on the Apply button if it's not grayed-out.
Click on Server Engine, then check the Active checkbox in the upper-left corner to start the server. It is also recommended that you set the Temporary Store size from the default of "-1" (unlimited) to something around 100MB. This will keep the free space on your server from getting eaten up by the log files.
Click on Plugins then ServerInfoPlugin and check the Active checkbox.
NexusDB is now configured and started. For applications to connect to it, the NexusDB Server will need to be started. You should probably add a shortcut nxServer.exe to the startup folder to ensure this, or you can manually start it each time you reboot this machine.
