Hello,

A client of us has an openserver 6 mp4 running with an application 
compiled for SCO 5. Sometimes the application, run on a windows terminal 
emulation, waits to show its information on screen.

Example:
Doing a query on the stock table. De databasemanager gives the result 
back. The first two articles are put directly on screen. It will wait a 
few seconds and shows the rest.

I can see with RTPM (default settings) the system calls are very large 
and showed in red. Both CPU's are used by 25% average.

Now SCO 6 has an dynamic kernel with dynamic parameters.
But is there a way to increase some parameters to decrease the system calls.

Regards,
John Kuiper

Morning John,

To get a better understanding of what is happening on your
system you should use sar(ADM) to analyse what is
happening on your system. The TA at:

describes how to use sar(ADM) to perform this analysis.

Hello John,

The sar inputs looks fine. The averadge idle time is 90%. The server is 
not swapping at all.
I think the "hp ProLiant ASM XL Monitor" causing this problems, but I'm 
not sure. Now it's season time and I don't want to stop it right now. 
After the season it's not so busy anymore and shall try it.

I know (years back on 5.0) this application causes problems and we had 
to stop it. But it was another server, but also compaq (hp).
If it doesn't work either, than I shall reinstall the server.
