HP-UX SNAplus2 R7 General Information

Introducing SNAplus2
SNAplus2 Resources
The 3270 emulation program is available in both Motif and character-based versions.
The Motif 3179G emulation program provides IBM 3179G graphics display emulation.
RJE workstation daemon
SNAplus2 provides support for Remote Job Entry (RJE), enabling users to submit jobs to an IBM host
computer for processing. The RJE workstation daemon is the SNAplus2 component that handles transfer of
jobs to the host, as well as the output returned from the host.
Users can prepare jobs for submission to the host and add them to the queue for an RJE workstation at any
time, regardless of whether the RJE workstation is running. When the workstation runs, it submits to the host
any outstanding jobs, in the order in which they were submitted. It also routes to the appropriate destination
any output received from the host, as determined by the configuration.
The RJE workstation uses the node’s type 0–3 LU resources. In addition, SNAplus2 requires definitions for
the RJE workstations on the system. RJE workstation definitions are configured in the domain configuration
file. In addition to the SNAplus2 configuration, the operation of the workstation is controlled by a workstation
style file, which is maintained by the users of the workstation.
APPC Application Suite
APPC Application Suite provides SNA equivalents of common TCP/IP applications such as
ftp and
ping.
APPC Application Suite can be used to provide support for operations, such as file transfer, that are frequently
performed across a network.
For more information, refer to
HP-UX SNAplus2 APPC Application Suite User’s Guide.
Application Programming Interfaces
SNAplus2 supports applications written to the following APIs:
APPC applications
APPC applications use the node’s LU type 6.2 resources to communicate with another APPC or CPI-
C application on a host or peer computer, using a specified mode. The APPC API includes TP server
support, enabling applications to have greater control over starting transaction programs (TPs) and distributing
conversations to those TPs.
CPI-C applications
CPI-C applications use the node’s LU type 6.2 and mode resources to communicate with another APPC or
CPI-C application on a host or peer computer. A CPI-C application requires the same resource definitions as an
APPC application. In addition, a CPI-C application can have side information entries that provide information
about partner TPs, the LU and mode resources used to access a partner, and any security information required.
As well as the standard C-language CPI-C API, SNAplus2 also includes a CPI-C API for use by Java
applications. For more information, refer to HP-UX SNAplus2 CPI-C Programmer’s Guide.
HLLAPI applications
HLLAPI applications interact with the 3270 emulation program to automate standard 3270 tasks.
LUA applications
LUA applications normally use the node’s type 0–3 LU resources to communicate with a host application.
Alternatively, SNAplus2 provides support for “RUI Primary”, in which the SNAplus2 RUI application acts as
a host and uses the node’s type 0–3 LU resources to communicate with a downstream LU.
No additional resource definitions are required.
MS applications
MS applications provide Management Services functions for network management. An application can be
either NMVT-level or MDS-level, depending on the type of MS data it sends and receives. SNAplus2 performs
any data conversion that is required.
