This chapter provides an overview of SNAP-IX features and shows some of the basic configurations in which SNAP-IX can be used. It describes the major components of SNAP-IX and the SNA resources that are configured for and used by SNAP-IX, and provides an overview of SNAP-IX administration responsibilities and tools.
SNAP-IX is a software product that enables Solaris computers to participate in an SNA network that includes mainframes, PCs, and other computers. With SNAP-IX, you can access data and programs that reside on other computer systems, thereby increasing your computing power.
SNAP-IX includes the following facilities:
SNAP-IX 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 SNAP-IX, see SNA Support.
SNAP-IX 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.
SNAP-IX supports the following user applications:
3270 emulation
5250 emulation
Remote job entry (RJE)
NetView DM Agent (NDMA)
APPC Application Suite
For more information about user applications, see User Applications.
SNAP-IX includes application programming interfaces (APIs) that you can use to write user application programs or SNAP-IX administration programs. For more information about SNAP-IX APIs, see Application Programming Interfaces.
Within a TCP/IP local area network (LAN), SNAP-IX supports communication between servers (SNA nodes) and clients (Solaris or Windows computers). For more information about client/server facilities on a LAN, see Client/Server Support.
SNAP-IX provides support for Windows clients (running Windows 95 or Windows NT), enabling them to access SNA resources through SNAP-IX 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.
SNAP-IX includes several methods and tools you can use to configure and manage SNAP-IX servers and clients. For more information about SNAP-IX administration, see SNAP-IX Administration.
