SNAP-IX is a software product that enables Solaris computers to communicate with remote computers (IBM mainframes, PCs, or other Solaris computers) within an IBM SNA network. It provides SNA node type 2.0 and 2.1 support for communicating with host and peer computers; it also implements an APPN node, providing network node, end node, branch network node, or LEN node function, depending on its configuration. (See SNAP-IX Components.)
The SNAP-IX system defines resources that enable it to participate in the SNA network and support specific types of communication. Those resources are described in Node Resources.
With SNAP-IX, you can access data and programs that reside on other computer systems, thereby increasing your computing power. You can establish connections with several computers concurrently using different methods of communication: 3270 emulation, 5250 emulation, RJE, APPC, CPI-C, LU0, and LUA. In addition, the SNAP-IX API libraries provide support for SNA applications (LU type 0, 1, 2, 3, or 6.2), both on SNAP-IX servers and on Solaris and Windows clients. SNAP-IX also includes user applications. The optional NetView DM Agent package can be used to manage Solaris files from the host. APPC Application Suite provides SNA equivalents of common TCP/IP applications such as ftp and ping. For more information about application support, see SNAP-IX Applications.
Passthrough features enable computers in a local area network to access SNA resources through the local system, as described in SNAP-IX Passthrough Services.
SNAP-IX also supports client/server configurations as described in Client/Server Support.
For an overview of the advantages offered by SNA networking with SNAP-IX, see Benefits Provided by SNAP-IX.
SNAP-IX implements an APPN node to communicate with other nodes on the SNA network. This provides LU 6.2 support for 5250, APPC and CPI-C capabilities, as well as LU 0, 1, 2, and 3 support for 3270, NDMA, RJE, LU0, and LUA communications.
SNAP-IXcan operate as any of the APPN node types (network node, end node, branch network node,or LEN node), depending on its configuration. Certain functions are supported only on network nodes, or only on network and end nodes, as defined by the APPN architecture. These differences are indicated where necessary in this manual; where no differences are indicated, the information applies to all node types.
