Welcome to the AcuServer file server, a client/server technology that provides remote file access services to ACUCOBOL-GT® applications running on UNIX and Windows TCP/IP-based networks.

With AcuServer, your applications gain:

(Some applications that contain hard-coded paths to files must be modified to use the FILE_PREFIX or CODE_PREFIX environment variable, or to include the name of the file server in the path. See Accessing Remote Files for a discussion of name strategies.

AcuServer does not require that you recompile your existing programs. Programs compiled with any version of ACUCOBOL-GT can be executed by any later version of ACUCOBOL-GT. ACUCOBOL-GT runtimes are available for most UNIX and Windows platforms. Contact our customer service representative for a current list of supported platforms.

AcuServer can be combined with other extend technologies to provide access to data in networked, client/server, and distributed computing environments. It can be used with the ACUCOBOL-GT Web Runtime to provide access to data over the World Wide Web (with permission). It can be used with ACUCOBOL-GT's CGI technologies to provide Internet access to data through an HTML front end. And it can be combined with AcuConnect® to facilitate file distribution and optimize network performance in a distributed computing setting.

Pictured below is a simple AcuServer network. ACUCOBOL-GT applications running on UNIX and Windows client systems access and store data files on a common UNIX, Windows NT, Windows 2000 to 2008 file server running AcuServer. More complex networks might incorporate multiple AcuServer file servers supporting dozens of client machines running multiple applications.


Note: Your AcuServer version number and your ACUCOBOL-GT runtime version number should match. Programs compiled with earlier versions of ACUCOBOL-GT can be executed, provided that the version of ACUCOBOL-GT runtime and AcuServer are the same.

Unless otherwise indicated, the references to Windows in this manual denote the following 32-bit versions of the Windows operating systems: Windows XP, Windows NT 4.0 or later, Windows 2000, Windows 2003; and the following 64-bit version of the Windows operating system: Windows Server 2003 and 2008 x64. When necessary specific version numbers are used (Windows 2000, Windows NT 4.0, and so on).
