Use the CPU Allocation tab to get a visual indication of how the CPU resources on the Exadata database servers are allocated. The following image shows a cluster with two hosts, each with 96 virtual CPUs (vCPUs). Several databases were deployed on the system, and each database was allocated 96 vCPUs, making it an over-subscribed system. Of these, only a few databases are actually impacted, and are depicted in the FAIL state.
