 » Index

SNAplus2 is a software product that enables HP-UX computers to participate in an SNA network that includes mainframes, PCs, and other HP-UX computers. With SNAplus2, you can access data and programs that reside on other computer systems, thereby increasing your computing power.

SNAplus2 includes the following facilities:

SNA communication facilities

SNAplus2 nodes can operate within an SNA subarea network, within an APPN network, or within both at the same time. For more information about SNA support supplied by SNAplus2, see “SNA Support”.

Passthrough services

SNAplus2 includes services that support communication between a host and computers on a LAN, making it possible to reduce the number of communication links to the host, simplify configuration of SNA nodes, and provide host access for computers that have no direct link to a host. For more information about passthrough services, see “Passthrough Services”.

User applications

SNAplus2 supports the following user applications:

  • 3270 emulation

  • 5250 emulation

  • Remote job entry (RJE)

For more information about user applications, see “User Applications”.

Application programming interfaces

SNAplus2 includes application programming interfaces (APIs) that you can use to write user application programs or SNAplus2 administration programs. For more information about SNAplus2 APIs, see “Application Programming Interfaces”.

LAN facilities

Within a TCP/IP local area network (LAN), SNAplus2 supports communication between servers (SNA nodes) and clients (HP-UX or Windows computers). For more information about client/server facilities on a LAN, see “Client/Server Support”.

Windows clients

For Windows

SNAplus2 provides support for Windows clients (running Windows 3.11, Windows for Workgroups, Windows 95, and Windows NT), enabling them to access SNA resources through SNAplus2 servers. The APIs provided for Windows clients support 3270 and 5250 emulation and enable the development of custom applications. These APIs implement the WOSA standards and are compatible with the APIs provided with Microsoft's SNA Server.
