Before you use the Exalytics Capacity on Demand Utility to configure the number of active core processors on an Exalytics Machine, keep the following guidelines in mind:
You can use the Exalytics Capacity on Demand Utility to configure active core processors on a non-virtualized Exalytics Machine only. This utility is not available on an Exalytics Machine configured for virtualization.
Each Exalytics Machine is shipped with all core processors enabled. Decide carefully about initially decreasing the number of active core processors on the Exalytics Machine. Once you decrease the number of active core processors on an Exalytics Machine, you can only increase them and cannot decrease them further.
For example, if you initially decrease the number of active core processors on an X4-4 Exalytics Machine from 60 to 20, you can then only increase the number of active core processors and cannot decrease them further to 16, 12, or 8. Table 8-1 shows the configurations of active core processors on Exalytics Machines.
You can increase the number of active core processors in increments of four only.
