High CPU usage by Oracle

Hi,
I would like help with this problem I am grappling with since yesterday. One of the test boxes with Sun Solaris 2.7 OS and Oracle 8.1.7.2 on it has started showing 97% and above CPU usage mostly by Oracle . It has slowed down the application to a point where the testers can not test. Does any one have any idea why Oracle would suddenly hog CPU so much? The normal CPU usage on these boxes is 2%-3%. All help is greatly appreciated. Thanks in advance.

Thanks,
