Running Superbase on LANtastic
Superbase can run on any Microsoft Windows compatible network. To run Superbase on a LANtastic network, some additional setup is required. This is because LANtastic relies on the DOS SHARE.EXE program to handle file locking. This technote explains how to setup LANtastic servers, workstations and users for Superbase in a typical LANtastic environment.
Typical configuration
Typically, on a LANtastic network, Superbase is run on the workstations while the data files and the network control file (SUPERBAS.NET) reside on the server. If the server also acts as a workstation running Superbase, performance decreases because the network's CPU time-slice is reduced. For maximum performance, use a dedicated server wherever possible.
Server setup
 Install the network version of Superbase on the server.
Check the MAX FILES OPEN statement in the Server start up parameters. It should be set to MAX FILES OPEN = 255 or MAX FILES OPEN =USE CONFIG.SYS. If the latter is true, the CONFIG.SYS file on the server should contain the statement FILES = 255.
Load the SHARE.EXE program in the CONFIG.SYS file on the server. Use parameters that allow enough space and enough locks to handle all users and databases. The following example is enough for about 6 users, depending on your system configuration. 		INSTALL = C:\DOS\SHARE.EXE /F:4096 /L: 200
	4.	Place all data files (.SBF, .SBD, .1, and so on) in a network directory.
	5.	The NETDIR = statement in the Superbase section of the WIN.INI file must point to a 			network directory that all users have RWED access to. Superbase automatically creates 			the SUPERBAS.NET file in this location when a user enters the network version of Su-			perbase. The SUPERBAS.NET file keeps track of Superbase file locks and access 			modes.
Workstation setup
Load the SHARE.EXE program in each workstation's CONFIG.SYS file. Use parameters that allow enough space and enough locks to handle all users and databases. The following example supports about six users.
			INSTALL = C:\DOS\SHARE.EXE /F:2048 /L:40
	2.	Copy the network version of Superbase (SB4W.EXE), the Form Designer 			(SBFD4W.EXE), and the dynamic link libraries (*.DLL) to a Superbase directory on a 			local drive.
	3.	The NETDIR = statement in the Superbase section of the WIN.INI file must point to the 		same network directory as for all other workstations and the server. The NETDIR for all 		workstations must point to the same physical location because the SUPERBAS.NET file 			which controls multi-user file access is created in this location. If it does not, users will 			not have access to all of the files. For example, these lines should be in your WIN.INI 			file: 
			[Superbase]
			netdir = f:\sbnet
User setup
Each user must have full network rights (RWED) to the directory listed for the NETDIR statement.
That's all there is to it. If you followed all the instructions in this technote, you should have no problem running Superbase on your LANtastic network.
