If your running oracle 10.2.0.3 on Windows, you may find the the System Event log being filled with Start Stop messages for the WMI Performance Adapter … every few minutes or even more often…
Event ID:7036 The WMI Performance Adapter service entered the running state.
Event ID:7035 The WMI Performance Adapter service was successfully sent a start control.
Event ID:7036 The WMI Performance Adapter service entered the stopped state.
I hate Event Log Spam, then again, I find the event log very 1990’s 
Turns out it’s due to an old NT4 dll, pdh.dll in the %ORACLE_HOME%\bin directory.
The fix is easy, stop your dbconsole service(s), rename the file and restart the dbconsole service(s).
The metalink docid is 454987.1
This feels like a much better solution than the autostart option for the service which has been mentioned around the web.
Why didn’t the latest critical update for oracle (oct 07) include this, I consider this to be very critical as it obscures important the event log entries…hmmm
Side Note: The McAfee McShield service entered the running state is a bug in the version 8.50i of viruscan
