Thomas, thanks for your post.
However I don't see where I can match the threads on NT to what I see in Task Manager. Am I missing something?
To be more explicit, here's what I've got:
SQL> select * from dba_nt_threads;
ID_THREAD B NAME SID SERIAL# USERNAME STATUS OSUSER
--------- - ----- --------- ---------- ------------------------------ -------- --------
3144 1 PMON 1 1 ACTIVE SYSTEM
2436 1 DBW0 2 1 ACTIVE SYSTEM
2972 1 LGWR 3 1 ACTIVE SYSTEM
3172 1 CKPT 4 1 ACTIVE SYSTEM
2976 1 SMON 5 1 ACTIVE SYSTEM
3380 1 RECO 6 1 ACTIVE SYSTEM
2840 11 1973 LISA ACTIVE lkoivu2
900 12 2 DBSNMP INACTIVE SYSTEM
8 rows selected.
I see no processes in task manager that correspond to any of the numbers listed in ID_THREAD. In fact my sessions script used to reference spid, but I took it out because I couldn't make sense of it on Windows.
Thanks for any insight.

Create the view dba_nt_threads and query it, then run the monitor CPU per
session. These are not my scripts --- I'm pretty sure that they were
posted here by others --- but I did not capture the information on who
originally wrote them. My apologies. HTH

Please respond
to ORACLE-L
HI all
We have a consistent problem of CPU utilization 100%. We have had this
problem since Saturday, but it automatically subsided, I mean went back to
normal after a few hours, and remained normal on Sunday as well. But its
back to 100% since morning, that is when the load on the server has gone up
again to 100% and over all work is non-existent.
Our machine is Compaq Proliant ML350, 900 MB ram, 933 single Processor,
Database size of roughly 5 GB. WINNT4.0, Oracle 8.1.7.
I have checked the temporary tablespaces, they are normal.
We have a 24x7 environment, a hospital, so please can you suggest the areas
to look in to, its really very urgent.
Regards,
Hussain
