Chapter 8. System upgrades  319 Capacity on Demand  (CoD) The ability of a computing system to increase or decrease its performance capacity as needed  to meet fluctuations in demand. Capacity  Provisioning  Manager (CPM) As a component of z/OS Capacity Provisioning, CPM monitors business-critical workloads that  are running on z/OS on  z14 systems.  Customer profile This information is on Resource Link, and contains client and system information. A customer  profile can contain information about more than one system.  Full capacity CP  feature For z14 servers, feature (CP7) provides full capacity. Capacity settings 7nn are full capacity  settings. High-water mark Capacity that is purchased and owned by the client. Installed record The LICCC record is downloaded, staged to the Support Element (SE), and is installed on the  central processor complex (CPC). A maximum of eight different records can be concurrently  installed and active. Model capacity  identifier (MCI) Shows the current active capacity on the system, including all replacement and billable capacity.  For  z14 servers, the model capacity identifier is in the form of 7 nn , 6 yy , 5 yy , or 4 xx , where  xx ,  yy,  or  nn  indicates the number of active CPs: GLYPH<SM590000> 1 - 99 in decimal and A0 - H0, where A0 represents 100 and H0 represents 170, for  capacity level 7 nn . GLYPH<SM590000> yy  can have a range of 01 - 33.  GLYPH<SM590000> xx  can have a range of 00 - 33. An all IFL or an all ICF system has a capacity level of 400. Model Permanent  Capacity Identifier  (MPCI) Keeps information about the capacity settings that are active before any temporary capacity is  activated. Model Temporary  Capacity Identifier  (MTCI) Reflects the permanent capacity with billable capacity only, without replacement capacity. If no  billable temporary capacity is active, MTCI equals the MPCI. On/Off Capacity on  Demand (CoD) Represents a function that allows spare capacity in a CPC to be made available to increase the  total capacity of a CPC. For example, On/Off CoD can be used to acquire more capacity for  handling a workload peak. Features on Demand  (FoD) FoD is a new centralized way to entitle flexibly features and functions on the system. On z196  and z114, the HWMs are stored in the processor and memory LICCC record. On  z14, z13 and  zEC12 servers, the HWMs are stored in the FoD record. Permanent capacity The capacity that a client purchases and activates. This amount might be less capacity than the  total capacity purchased.  Permanent upgrade LIC that is licensed by IBM to enable the activation of applicable computing resources, such as  processors or memory, for a specific CIU-eligible system on a permanent basis. Purchased capacity Capacity that is delivered to and owned by the client. It can be higher than the permanent  capacity. Permanent/ Temporary  entitlement record The internal representation of a temporary (TER) or permanent (PER) capacity upgrade that is  processed by the CIU facility. An  entitlement record  contains the encrypted representation of  the upgrade configuration with the associated time limit conditions.  Replacement  capacity A temporary capacity that is used for situations in which processing capacity in other parts of  the enterprise is lost. This loss can be a planned event or an unexpected disaster. The two  replacement offerings available are Capacity for Planned Events and Capacity Backup. Resource Link The IBM Resource Link is a technical support website that provides a comprehensive set of  tools and resources. It is available at the IBM Systems technical support website.
