"The mainframe is dead!!!
Long live the mainframe!!!" Yes, we have all heard
about the demise of the mainframe, but what are those systems
people buying and using? The reality is that mainframes
are not going away. There is still a large amount of mainframe
hardware in use, and more is being purchased. The investment
in this legacy hardware and software, both application
and utility, is too great to be ignored by CEOs of companies.
On the other hand, the number of technical people that
know and understand SNA or Bisync is dwindling rapidly.
Add to this the decreasing number of vendors selling legacy
connectivity software, and you can see the need for a firm
with experience in this area.
TPS® has been providing legacy connectivity software for
the past fifteen years. Over that time, we have developed a complete
set of SNA, Bisync and Telnet solutions. These solutions run
on multiple platforms and operating systems.
Many mainframe shops are looking for ways to transition from
SNA to IP, but continue to use their legacy downstream hardware.
TPS® offers a number of products that can assist in this
Primary creates a virtual SNA mainframe on a
* TPS®/NFM (NetWork File Manager) can run IP and SNA transfers simultaneously.
* TPS®/PCA (Protocol Conversion
Application) assists sites transitioning
from SNA to IP by converting SNA traffic to IP sockets and vice-versa.
Client and TPS®/TN3270
Server creates a gateway between SNA applications and downstream TN3270 clients connecting
via TCP/IP links.
A number of legacy sites are looking at moving their applications
to a UNIX® system and using the mainframe as a File Server. TPS® has
integrated its SNA software with a CICS package that runs on
UNIX®/Intel® platforms thus allowing the migration of mainframe
CICS applications to these platforms.
TPS®/NFM can be utilized to replace the NetView functions
on the mainframe by having the mainframe as a client. By taking
this approach, the mundane file distribution and pickups can
be performed on a UNIX® platform. This approach returns cycles
to the mainframe for use in the business applications of the
Thus, whether you are a software vendor needing to solve a connectivity
problem relating to your package, or a company trying to transition
to a client/server environment, TPS® has the connectivity
solutions for you to be successful in your endeavor. If none
of our solutions meet your specific connectivity requirements,
please contact us. We
can put our twenty five years of experience to work for you.
