The Instant Capacity software primarily maintains complex-wide information about the usage rights and activation of system components. (If you are using Global Instant Capacity, then the software also maintains group-wide information about usage rights. See Chapter 7 “Global Instant Capacity” for more information about GiCAP.) The software monitors the number of usage rights for the entire complex for each type of component.

The Instant Capacity software authorizes activation at will of cores, cells, and memory if allowed by the system usage rights. You will not be allowed to activate additional components if that action would take the system out of compliance.

For example, if your Instant Capacity contract specifies that your system contains 12 cores with usage rights and 4 cores without usage rights, you may have up to 12 cores activated at any one time, and 4 cores must be inactive at all times.

The Instant Capacity software can determine the following compliance aspects:

  • Whether a system is in compliance or out of compliance with the Instant Capacity contract

  • The number of additional cores that can be activated

  • The number of additional cells and the quantity of memory that can be activated

The enforcement methods used by the software include:

  • Not allowing activations which cause the system to be out of compliance

  • Deactivating cores on boot

    • Automatic deactivation of cores at boot time if temporary capacity has been exceeded and the number of active cores continues to exceed the number of core usage rights for the complex (see “Temporary Instant Capacity Expiration and Compliance Enforcement”)

    • In an integrated virtual partition environment, preventing a virtual partition from booting if the number of assigned cores is greater than the number of intended active cores for the nPartition (see “Boot Time Compliance”)

  • On OpenVMS systems, the ICAP_SERVER dynamically deactivates active cores that exceed the number of core usage rights for the complex
