RE: 5250 emulation locks up on XP

["Jim Damato" <jdamato@xxxxxxxxxxxxxxxxx>]

* Happens on different apps.
* Not easily replicated.  We can bang on a workstation for hours and not
lock.  It does, however, only happen to multi-session users.
* No predictable buffer behavior -- can happen when they key one screen
or four screens ahead.
* I'm gonna get our PCS group to try Win 2K.
* The PC models are probably the same.  I'll see if I can get someone to
try unlike hardware.
* The applications will never be improved.

I'll keep you posted.  Much thanks...

Jim,

I haven't seen anything like this but other things I'd be trying to
isolate
the problem:

Does it always happen with the same app or different apps?  Or maybe it
always happens on the same screen?  (If lockup occurs with different
applications or screens then you can likely rule out the application as
the
problem).

Could you replicate the problem by just holding down a key on the
keyboard?
(maybe it's a certain sequence of keys causing the problem)

Does it happen when the users type too far ahead? (could be filling up
the
type ahead buffer)

Maybe the buffer problem is in Windows XP.  It didn't happen on Windows
2000?  Could you install Windows XP on some of the old hardware and see
if
you get the overflow problem with the old hardware but with Windows XP?

Maybe it's a PC hardware problem.  Are all the new Windows XP machines
the
same model?  Do you have a different model of PC running Windows XP that
also has the lockup?  Could you install Windows 2000 on the new hardware
and
see if you get the lockup?

Also, have you taken a look at these applications to see if you can
speed up
their interactive performance?  If they are doing a lot of updates that
take
awhile maybe throw some data in a data queue and let a batch program do
the
updates.  Maybe the screen I/O could be tweaked with some changes to the
display file and the way the program formats the screen.
