RE: Database using 100% of CPU

It is nt, it is because it is unstable and crashes every 1 second, you just haven't noticed it.

Seriously though, first verify the processes are oracle and not something else using task manager.

Then if they are oracle. Look into v$session and find active sessions. Trace them back with their sql addresses.

Also look into dba_jobs_running for any running jobs.

I have seen similar problems where a job was scheduled as interval 'sysdate' which has it run continously right after another, a few of these will do such a thing.

Steven:

I also have this happen on one of our smaller DBs running NT. I haven't found a cause yet either. Rebooting seems (so far) to be the only cure. If you get any replies would you please summarize to the list?

Thanx,
Mike

We are having a problem with our database - it is using 100% of the CPU.
This has only started happening recently, and restarting the database
temporarily stops it happening - it usually recurrs a few hours later. There
are no jobs running, and at the moment there are no active connections.
Obviously something has kicked this off, can anyone shed any light on this
or suggest how to find out what is running on the db?


Thanks in advance,

Steven H.

(Oracle 8.1.6.0.0 EE on NT 4 SP5)
