Yeah there was a sudden burst of activity in data insert, updates and deletes over the weekend as a result of a new app module being tested. But the client app uses Java code and is not in the database. So its nothing I can ask them to remove. On the other hand sudden bursts of data activity is something that might very well happen in the normal course of the application so I guess I need to be prepared for it..Thanks, for the suggestion.

Has there been any changes in the applications? I had someone put in new code this weekend and it sent my CPU up over 80%. When I saw that Monday morning, I had the developer take the code out and my CPU dropped back down to around the 5 - 10%. From my little experience I have quickly learned that when you see something like your CPU go up, check what modifications to applications have occurred.

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,
