Hi Ghassan

Currently we only use roughly 45% CPU per node in peak time (we have 22 Cores per EXA database node) but the runqueue is around 40 due to high number of processes. If we move to Exadata CC I guess during peak time (4 to 6 hours per day) I must scale to 22 core per node at minimum otherwise I will have CPU contention. Is the scaling automatic and dynamic? How does the database deal with the change of CPU_COUNT? I also have some unexpected peak time in different time of the day (sometimes the business users run batch without notifying the database team), how Exadata CC deal with such situations?
