Have you looked at the event tables?

Perhaps running a statspack report from now to the next 10 minutes and look at the biggest waiters.

If it is unix, look for the process which is eating up the resources, query v$process to get the process address, then use that to get the session, then use the sql address to find the sql.\

Also query v$session for active sessions which are active for a long time.

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,
