Roger,

I am not familiar with using CA over twinax. If I understand what you're
saying, your client's current connection from PC to V4R4 via twinax is SNA,
therefore the APPN connection between the two 400s allows them to get a
signon screen on V3R2 box without doing STRPASTHR. You would like to be able
to continue to do this (without STRPASTHR) after the conversion to CAE and
TCP/IP. The V3R2 box has no LAN connection, only SDLC to the V4R4 box.

The only thing I can think of is it might be possible to do what you want
with Anynet. If you were to configure Anynet between the 400s, it could
encapsulate the TCP/IP traffic in SNA and pass it over the SDLC line. If the
TCP/IP routing were set up appropriately on the V4R4 box, perhaps you could
set up a CAE session with the IP address of the V3R2 box and the V4R4 box
could route the TCP/IP traffic. You might also want to read about IP
Forwarding, because I think that would play a part. I am only speculating
about all this. Maybe someone with Anynet experience could comment on
whether this would work.

Hello,

I will be moving a client from twinax and Client Access (V3R2M0) to CA
Express (V4R4M0) in the near future. Right now with twinax they
connect to two different i400s. The i400s are connected together with
SDLC only. The connection specifies the second system as APPN so when
the connection is requested it goes to the first system and it passes
the connection to the second. Can CAE be configured to pass through
one i400 via TCP and connect to the second one via SDLC or will they
have to actually signon to the first and STRPASTHR to the second one?
The first system is at V4R4M0 and the second is at V3R2M0 (I know, but
is for history data in an application that would have cost a mint to
move the license to a RISC model).

Basically from:
PC (CA)----Twinax----i400----SDLC----AS400
to:
PC (CAE)----Ethernet/TCP----i400----SDLC----AS400

If this can be done without STRPASTHR please point me to the books as
my searches have been frustrated so far.

Thanks,

Roger Vicker, CCP
