Abstract

Disclosed is a method of performing TN3270(E) performance management and enabling end-to-end problem determination. TN3270 and its extension TN3270E are standards that define how to perform 3270 terminal emulation when clients are connected into a Systems Network Architecture (SNA) network via Transmission Control Protocol/Internet Protocol (TCP/IP). The method being disclosed is intended for use at the same host where a SNA System Services Control Point (SSCP), TCP/IP Host (implementation) and a TN3270(E) server reside.

TN3270(E) Host Based Correlation and Performance Management

   Disclosed is a method of performing TN3270(E) performance
management and enabling end-to-end problem determination.  TN3270
and its extension TN3270E are standards that define how to perform
3270 terminal emulation when clients are connected into a Systems
Network Architecture (SNA) network via Transmission Control
Protocol/Internet Protocol (TCP/IP).  The method being disclosed is
intended for use at the same host where a SNA System Services
Control Point (SSCP), TCP/IP Host (implementation) and a TN3270(E)
server reside.

   The TN3270(E) server (TCP/IP based) acts as the gateway
between its IP clients and the SNA Network for enabling access to SNA
Target Applications.  Access is enabled by mapping an IP client to a
SNA Secondary Logical Unit (SLU) that is associated with a target
application.  An IP client is identified via local and remote IP
address and port pairs.  When the IP client is connected into the SNA
network it is associated with a SNA Secondary Logical Unit (SLU).

   Customers want end-to-end problem determination for TN3270
sessions.  The first part of this disclosure is a method for
providing access to the mappings of the TN3270(E) clients with their
SNA connections and keeping track of TN3270(E) client
characteristics.  Providing access to the mapping of an TN3270(E)
client to its SNA connection enables the identification of the total
path of a TN3270(E) session.
     Enhance the TCP/IP implementation that runs on the same
    host as the SSCP and TN3270(E) server to store the mappings of
    its IP Clients to their SNA connections along with related
    TN3270(E) client specific information...
