Terminal Server 2000 and DOS application

[Guest]

Hi.

We have a problem that a DOS program that we run on a TS client hangs. Is
there any known problems with this? Anyd ideas? Program for better memory
handling? Keyboard input issues?

Please help!

Hi Magnus,

We have a problem that a DOS program that we run on a TS client
hangs. Is there any known problems with this? Anyd ideas? Program for
better memory handling? Keyboard input issues?

is it running at 100% CPU? Test TameDos, it's cheap, does the job,
install with defaults and forget the problem.

HI!
There is something about running 16-bit apps on w2000 with TS. Look for
this in the search.microsoft.com ( it's a try!!)

TAMEDOS is nice for DOS Applications, but I prefer an application that
manages all processes, i.e. Relevos, Appsense, TMU Limit, Threadmaster (free)
or Aurema Armtech.

Hi Patrick,

but

TAMEDOS
and
Appsense
Threadmaster (free)

are two totally different things, I think. Tame stops this keyboard
polling (sorry for my english) but lets the application run at 100% if
it is really working while appsense and threadmaster would permanently
limit the cpu-usage. So, if you set 25% in threadmaster the dos
application would never get 100% CPU (not even for a second) as it
permanently tries to use 100% even if it is doing nothing.

BTW for me tame and threadmaster are doing their jobs perfectly. Esp.
threadmaster can send messages to users when it starts slowing down an
application (appsense cannot do this, it just can send a message when
one uses too much memory). And both, threadmaster and appsense cannot
stop one of my apps using 32% (4 CPUs, 25% is 100% of one cpu, win2k
dual) - strange but true.

The most common problem with DOS or 16 bit applications on NT Based OS is
that constant keyboard polling uses a lot of CPU time. On a single user
system this isn't a problem, because no one else cares if your CPU is at 80%
consistently, and you probably don't even notice.

On a multi-user system this becomes a huge problem because two instances or
more of the 16 bit application can quickly saturate the CPUs, making all
sessions slow to a grinding halt.

TameDOS can alleviate this, however I prefer an application that prevents
any application from dominating the server's resources (not just DOS
Applications). Imagine you have a user with an excel spreadsheet with 50,000
rows of data who wants to subtotal and resort them, or who wants to encrypt a
zip archive containing 100MB of files. Either of these actions can peg the
CPU at 100% until the process is complete.

Applications like WMSoftware's Relevos, RTOSoft's Relevos, Appsense
Performance Manager, TMUrgent TMULimit, Aurema Armtech, Threadmaster (free)
can all prevent this from happening. TameDOS only helps DOS/16 bit apps.
