- Capacity-on-demand may only be used to decrease the number of active processor cores during initial installation. After initial configuration, the processor core count can only increase on a system, up to the maximum. It is the customer's responsibility to acquire the additional software licenses.
- Reducing the number of active cores lowers the initial software licensing cost. It does not change the hardware cost.
- The minimum number of processor cores that must be enabled is half of the physical cores on each processor. For Oracle Exadata Database Machine X4-2 systems, the minimum is 6 per processor (12 per database server). For Oracle Exadata Database Machine X4-8 Full Rack, the minimum is 8 per processor (64 per database server).
- Additional cores are increased in 2-core increments per server on Oracle Exadata Database Machine X4-2, and in 8-core increments on Oracle Exadata Database Machine X4-8 Full Rack. Database servers in the same system can enable a different number of cores
