The CPU becomes normal after the database is shutdown. So it's Oracle that is causing problems. I thought that it would be some rollbacking and roll-forwarding going on but, since morning, I don't think so. So I have some clues that it has something to do with Temporary tablespace as it had gone up to 10GB and all of it was being used. Although now temporary TS is down to 50% usage but smon is taking hell of a long time to clean up, don't you think. So that's why, as per my discussion with Regis, I have created another temporary tablespace and assigned it to all the users and trying to drop the old temporary tablespace, but haven't had much luck with it.
Any ideas

Subject: RE: Oracle taking 100% CPU
Hussain - Once you clear up some archive space, Oracle will resume
immediately. You don't need to bounce the database.
What is the system doing besides taking 100% cpu? W2K Task Manager offers
much more information, like I/O activity and CPU by process. This may
provide more clues.
Normally Oracle will take care of itself without intervention. My first
thought is that you had a lot of pending work since it couldn't archive.
Then you killed sessions which means Oracle must roll back transactions.
Offhand it sounds like Oracle is still recovering. Look for heavy disk
activity.

HI all,
We have a development server, a replica of the production. Some process
produced a lot of archives and it ran out of archiving space. Now it was the
only location specified for the archives and it was mandatory. So when no
space was left on it to store the newly produced archives, it should have
stopped working. But it didn't. I deleted the archives and closed every
session and shut down the database and restarted it. But eversince I
restarted it, (and I have done it 3-4 times already) Oracle is using
100%CPU. I have left the server on, without any body connecting to it,
(users can connect as the database is OPEN without any problem, its just
some transaction-cleaning or background process which is going on) but the
server remains unchanged i.e. using 100% for over an hour (after an hour I
shut it down and restarted and it still is the same)
There is no unusual entry in the alert lofile or any trace files. I can't do
any query to find out anything, as the system is so slow. There is no
problem of space either. "Event viewer" of Win2000 also shows nothing
unusual or new.
Any ideas, its somewhat urgent.
Hussain
