What a mess!
I suspect you saw APPC and assumed APPN - a false assumption I very
strongly suspect.
Yes. I saw APPC and thought there might also be an APPN piece to this.
I found a "IBM WebSphere Developer for zSeries Prerequisites",
SC31-6352-05, document and the nearest it got to suggesting VTAM was
required was the "IP Services component of IBM Communications Server"
which rather clearly indicates that VTAM, the *SNA* Services component
of IBM Communications Server, is *not* required. It did, however, rather
oddly, mention APPC - and also ISPF. This, by the way, is what prompted
the "what a mess" or perhaps "dog's dinner".
I also found ""IBM WebSphere Developer for System z Version 7.0, APPC
and WebSphere Developer for System z", SC23-5885-00. I'm guessing this
document has been put together as a way of explaining how to set up
APPC, note specifically APPC/MVS, because it is wanted for one of the
"under-the-covers" functions purely *within* z/OS.
I believe the "under-the-covers" function is "WEBSPHERE DEVELOPER - TSO
COMMANDS SERVICE - THIS FORMAT DISPLAYS RESULTS OF ISPEXEC AND NATIVE
TSO COMMANDS" as I found in the comments of one of the "server" jobs.
Moreover, the reason for ISPF is in order to support setting up the
APPC/MVS environment - and maybe the environment of some other z/OS
products. It's all a while ago for me now but I believe I managed to set
up my APPC/MVS environment purely with batch jobs so I *think* ISPF is
really optional for APPC/MVS.
So, it looks like the communication between z/OS and the Windows PC is
purely IP. I got a hint that maybe TN3270 was also used from that
presentation. You'd better work through the manuals to be sure.
That makes sense with what I observe.
If you need some help with the APPC/MVS side, I did keep some examples
of my playing with APPC/MVS long ago and the SC23-5885-00 manual
reminded me rather precisely of those samples I kept. So do let me know
if necessary.
No. I'm working with it OK. I just thought it was interesting
how they do this and was a little curious what it meant was
going on under the covers.
