RE: Telnet Session Limit

<snip>

it's been my experience that keeping all these devices also slows down
ending and staring QINTER

At V5R4 the underlying code was changed so a subsystem that allocates
devices can do it multithreaded now.  Waaayyyy faster and better.
Avoids many of the locks as well.  For years I have set up systems to
have one subsystem allocate all of the on line devices, and then use a
routing program to transfer the job into a subsystem set up just for
that type of user. Say accounting, shipping, IT, and shop floor can all
have their own subsystems and by definition their own class as well.
Now you can control who can use what resources etc. very cleanly.  You
can put a check in there using some of the API's Scott Klement has
talked about to see how many sessions a user has open and limit it, by
the user profile.  Since it is CL and at V5R4 CL can cleanly get to most
of the APIs (Thank you Rochester and Guy Vig!!) you can do almost
anything you want. The program is smart enough to recognize operators
and push them to the controlling subsystem, and as an added bonus,
presents a nice screen that says:  "sorry the systems not available
right now" if the administrator has the user's subsystem down for any
reason.  Various folks have taught the advanced work management class at
COMMON, me, Paul Weyer, and most recently Larry Bolhuis.  If anyone
wants the code that accomplishes what I am describing, contact me or
Larry Bolhuis privately.
