Re: SNA based commands -- MIDRANGE-L

You can certainly not use SNA and do all the things you want to do.
5250 (LU7) is SNA based, but you can use TN5250 for terminal access.
File transfers using SNDNETF or SAVRSTOBJ can be rewritten to use FTP,
but you'll probably need to roll your own.

SNA is nothing more than another protocol on the i5, just like TCP/IP.
IBM has products and utilities that use SNA (like the SNADSish suite
of products), but the functions can all be performed using TCP/IP.

We are mainly using SNA communications for 2 sets of functions:

 - One is our connection between 2 servers that transports our Mimix
replication between the 2 servers.  This can be reconfigured as TCP/IP
within the Mimix application.

-  The second set of functions is the set of commands used by our
programmers to accomplish moving objects between systems... things like
SNDNETF, SAVRSTOBJ, and commands of that nature.  I read a good document at
that point that described which commands used SNA functionality as their
mode of communication.  Has anyone seen such a document?

We added a 2849 ethernet adapter to each of our last set of systems in
order to still maintain native SNA connectivity, but at this point we would
rather just try to use TCP/IP based communications for what we are doing
(we have no specific reason to keep things SNA).

Using Enterprise Extender is an option, of course, and we may find out in
the end that it's necessary to set this up for some portion of
functionality, but would be more interested in avoiding the SNA based
functions wherever possible.  IBM's not necessarily removing it, but we get
the feeling that we should be moving away from it wherever possible.

SNA is not a "thing" on the system. It's a structure that
the entire commuications system is based on. There are many
commands related to communications and that will take you down
a VERY long road.

Which SNA thing are you moving away from ? SDLC is probably the
most common thing, but we could be talking about a LOT of different
protocols supported by SNA. You are talking about a framework that
is woven through the entire OS. Pulling out SNA is not a minor issue.

I'm not really sure that IBM can do away with the SNA framework
entirely.

What are you moving away from ?

How much communications do you have ?
