About 10 years ago, I used a different way, via OE, to set a
timer that wakes up after x minutes to then go to sleep for
another y minutes.... (you can set the loop to terminate after
some number of wakeups... So running ISPF this was started using
=6 (?) in the active ISPF session as I recall. I seem to remember
having to hit PA1 or ATTN to get control back.
Since the TSO session appears active because of this minimal
amount of activity, it will not get logged off until you cross
the TIME limit. So if you have the SMF exit to keep that from
happening.....
Just an idea.

Is there any reason why idle users should not be forced off
the system.?
Sounds like very sloppy system management.to allow this.

Hmm. Still got an S522 overnight, so I guess that wasn't what
you meant?
TWT looks to have the same 24-hour limit as JWT? This is a dev
system, we don't want users forced at all. Surely that's not
unique, and doesn't require use of an exit?!

I think I did #2:
//DYNISPFM EXEC PGM=IKJEFT01,DYNAMNBR=200,TIME=1440
// PARM='%DYNISPF'
That's in my logon PROC. Is that what you meant? Yes, I know
very little about this end of z/OS (or most other ends).
I did make the change from IBMUSER and then log off and back
on to be sure I wasn't locking myself out!
Is there a way to look at the time limit for a running job? I
scrolled wayyyy right in SDSF and didn't see it.

JWT in
SMFPRMxx is documented as taking values 0001 to 2400. We have
a handful of users on a development system behind a VPN and
don't want them forced off ever. Is there an easy way to
achieve this?
Few remarks:
1. Use TWT instead of JWT. TWT is quite new (younger than me
;-) ). It is for TSO users.
2. Use TIME=1440 (or NOLIMIT for modern installations ;-) ) in
the logon procedure. It disables both JWT or TWT.
3. Don't forget about TCPIP settings. I can't remember the
name, but network folks like to drop inactive sessions. This
is independent from JWT/TWT, TIME=1440 and other TSO settings.
