Hello,
I installed Oracle9i (database), Oracle 9iAS, and finally Oracle9i CM-SDK. About a week or ten days after installing everything my machine (which is running Win2K-Pro), it started acting sluggish. For a 2.4 GHz Pentium IV with 1GB RAM, I thought this very odd. I checked the Task Manager and a process called nmupm.exe was consuming 90-99% of CPU. Searching the machine, I found the executable sitting in: c:oracle9iASbinnmupm.exe
If I just leave it alone, it hogs max CPU (95% or more) for as long as the machine is running (I have left it running for over 48 hours).
To make the machine usable, I just renamed the file (nmupm.exe.kill), then restarted the machine. The executable, naturally, does not start and almost everything else works fine. The only thing that fails to work is that the App Server's Enterprise Manager fails to display CPU usage and Memory Usage pie-charts. Instead I get an error message "The underlying data for the CPU/Memory usage chart is unavailable." This makes me suspect that it has something to do with the CPU/Memory Monitoring.
Can anyon tell me what this thing is?
What is it doing?
How can I rein it in and regulate its CPU usage?
Thanks,
Scott

I have the same problem with the 10g database on windows. nmupm.exe eats my memory and hangs or blocks some system programs as Internet Explorer.
After deleting the database (not the oracle software) everything was ok. Then I tried to start nmupm.exe as a standalone program (nmupm.exe diskactivity) and I had the old problem again.
nmupm.exe seems to gather some system information.
I too have installed the .Net-Framework on my computer.

This must be a very new one! I just installed Oracle 10g about a week ago and my "super computer" becomes a slow grinding machine! When I stop some services from the control panel, performance improves but I've not been able to zero in on which one helps the most.
For sure I know that stopping the Oracle database services does help a lot but I also observed that stopping the McAfee virus scan service does about the same thing (don't go that way if you don't want your PC to be infected).
And one last observation - my diskette drive light comes on after every approx. 20secs when this file runs. So I'm really suspecting that this nmupm.exe has something to do with some system checks but it does take a lot of CPU time.
Can anyone help please?
