Hi Michel,
Yes, I was looking at different opinions to isolate my problem.
I dont have much control over application, its a standard application from Oracle. I have already logged a case with metalink and they are investigating the same.
I have 2gbps connection from server to storage. 100mbps from client to server(This connection is not required once the job is issued from the client). The application node and the DB node is sitting in the Same Box(different OS users).
I can see that only CPU load goes upto 100% and Disk IO is neglegible.
Also, the Statspack shows no major issues. In 10046 event trace shows 2/3 of the time goes as wait event.
Your suggestions may help me to investigate the issue.
Regards,
Brayan.

You have 100%CPU consumption, who is working? who consume this CPU?
And as I previously said, investigate the application: why Oracle is waiting for it to send work?
Regards
Michel
