There is at least one VTAM session manager on the CBT tapes. I don't know what
it would take to port it to run under VM, but.. the price is right and it comes
with source. SOL is the name of the thing I think. -Paul

PVM might be an answer. It had both SNA and scripting capabilities, and its a
pretty decent session manager. NVAS would have been another option, but it
requires VSAM, so prob not viable over the long term.
If you had to roll your own, the IBM CCL code does have API libraries for some
SNA functions, or you could probably easily add SNA function to YVETTE.

Subject: VM-VTAM/VSCS question
The background to this question is that we have 95% of our VM users
accessing the system via TCPIP TELNET sessions. However we have a handful
of remote users still accessing us via SNA and efforts to convert these to
IP seem to continually meet roadblocks.
For a number of reasons we want to remove VTAM from our main VM systems
but we do also have a small 'server' system. Our idea is, as an interim
solution, we route all SNA traffic to VTAM on the small server and then
use a session manager on that server to allow users to access our main
systems. (Load is very low - maximum 6-8 users at any one time - 200 users
in total).
However, if we do this we would like to make it as transparent as possible
so I have some questions :-
1) Normally incoming terminal users use VSCS as the application -
could this be a different application (say a session manager).
2) If we stay with VSCS, can this be set up to automatically 'dial'
to a session manager userid
3) From the 'session manager' we would want to open a telnet session
to another VM system
4) Are there any recommendations for free/cheap session manager (or
tools with which to build one).
The ideal would be for the SNA session to point to an application on the
small server which would then, transparently, take the user over a telnet
session to the target VM. I suspect that this is one step to far and they
would, at least, have to make a selection from a session manager panel.
Any advice/help would be welcome.
With best regards / mit den besten Grüßen,
