INF: Running SQL Server on DEC Pathworks

  - Microsoft SQL Server version 4.2 for OS/2

SUMMARY

Version 4.1 of DEC Pathworks for MS-DOS supports LAN Manager Enhanced workstation functions and hence, named pipes. Therefore, SQL Server on a Pathworks server can be accessed from an MS-DOS-based Pathworks version 4.1 workstation.

MORE INFORMATION

DEC Pathworks (previously called PCSA) is an original equipment manufacturer (OEM) version of LAN Manager. Pathworks allows MS-DOS-based and OS/2-based workstations to access DECnet and thus establish a connection to a VAX. (To do this, DECnet's transport-level protocol stack must be used.) The latest versions of Pathworks are version 4.1 for MS-DOS and version 2.0 for OS/2. Version 4.0 for MS-DOS was based on the LAN Manager Basic redirector and thus does not provide named-pipe support for MS-DOS-based workstations. This means that MS-DOS-based clients cannot access SQL Server from Pathworks version 4.0.

Version 4.1 of Pathworks, which provides named-pipe support, has been released. This version can run the LAN Manager Enhanced redirector. There are three different modes of installing a Pathworks 4.1 workstation: Basic, Enhanced, and Enhanced with full LAN Manager version 2.0 capability. Of these three, only the Enhanced workstation with full LAN Manager capability provides named-pipe support. When a workstation is configured in this mode, it can access SQL Server.
