I am currently trying to understand what is happening on a rather large UNIX
installation runing Oracle.
At about 8:00am to 8:30am the system starts to use up to 99% system time. 0%
user time and 0% wait for I/O. the same happens at around 4:00pm to 4:30pm.
Rebooting the system seems to cure it, only to have the problem re-occur
later in the day. There seems to be no CPU time used by any process. The
sar reports only the system time being 99%.
Can someone please give me an idea of were to go and look? A program to run
or rm -r /* ;) - Anything please
Your cooperation is greatly appreciated....
