We want to restrict one user to a limited amount of CPU usage. I'm researching to see how best to accomplish this. I've read that oracle resource manager can be used to restrict CPU usage. We have only one user that needs to be restricted. The original request is to restrict this one user to not more than 25% of CPU. Can someone point me in the direction to find information that would help me determine if this can be accomplished via a profile using CPU_PER_SESSION and CPU_PER_CALL or if Oracle Resource Manager is a better choice. Also, is Oracle Resource Manager included with Oracle Enterprise Database 12C? Or, is an additional license required?
