RE: 100% CPU utilization, urgent

Frank,

I'm pretty sure they do:

SQL> select spid,program from v$process;

SPID PROGRAM

The last tid (12c hex) equals to 300: that's my thread after running Jonathans world famous kill_cpu script. You can checkout (after converting to dec) a few of the others too. This was the case on NT4 and I just showed this on W2K In perfmon you can find the thread_id in the Thread Object (don't confuse it with the perfmon's object_id!), and off course the cpu usage of the corresponding thread.

regards,
Mario
Btw I didn't see your earlier question, since I joined the list a few days ago, please send it to me if you want a more specific answer (or correct me if I'm wrong)

no, they don't !!! (at least NT4 with a SQLNet connection to a DB Server) (see my question I posted a few days ago)
