Enhancements Offered by SNAplus2 R6.0
The SNAplus2 family offers higher scalability and increased
functionality. Some of the enhancements and features include:
• A highly-scalable number of links, users and sessions limited only by
the available hardware resources (for example, the number of slots
for adapter cards, disk space, physical memory, etc.)
• Multiple LAN support (Token Ring, 802.3 and FDDI simultaneously)
• The ability to specify the path to the SNAplus2 programs, if
necessary
• Support for SNA over QLLC using the dual-port PSI card on D-class
servers
• SNAplus2 APPN End Node product, which:
— Allows remote LUs to be dynamically located as required instead
of being configured explicitly at the local system
— Allows a host that has the Dynamic Definition of Dependent LUs
facility to dynamically define the dependent LUs of this node;
this significantly reduces the host definitions.
— Using the DLUR function working in conjunction with DLUS on
the host provides the facility to route sessions for dependent LUs
across an APPN network, instead of requiring a direct connection
to this host.
• Support for the APPN Connection Network feature in a Shared
Access Transport Facility (SATF) environment (e.g. TR network)
(suppresses the definition of a Link Station between each pair of
communicating nodes).
• SNAplus2 API support compilation from C++ applications
• SNAplus2 RJE, providing:
— Checkpoint restart capability for retransmission of incomplete
RJE output data files; this can significantly reduce the
transmission time in case of a low quality line.
