Check the system that runs Oracle (UNIX, NT, etc.) and see if there is any symptom of CPU, Disks, memory Contentions.

What is the hardware, OS, CPUs (how many)?

Steve, and everyone else,

Well, that's not it. Buffer Busy Waits is near the bottem. SQL*Net Message from client is at the top, followed by Slave Wait and CPU used by this session.

Any other ideas? I will be a hero if I get a solution. Ruth
