Terminology
Term | Description |
|---|---|
4 hour rolling average (4HRA) | CPU consumption, measured in MSUs 4HRA is calculated by RMF using the last 48 5-minute buckets and written into the type 70 record of the z/OS image in which RMF is running. While RMF in each z/OS image records the CPU consumption of all LPARs on the same CPC, the 4HRA metric is available only for the host LPAR (the LPAR in which this record is created). |
AWLC | Advanced Workload License Charges |
AEWLC | Advanced Entry Workload License Charges |
CDB | Capacity Database Web Services (referred to as CDB in earlier versions) |
CMP | Country Multiplex Pricing |
CMLC | Country Multiplex License Charges |
Central processor complex (CPC) | Physical collection of hardware that includes main storage, one or more central processors, timers, and channels For more information, see mainframe terminology in the IBM Knowledge center. |
CoC | Collocated container |
EWLC | Entry Workload License Charges |
FWLC | Flat Workload License Charges |
Job/STC | Batch job or started task that is running in a z/OS environment |
LC | LPAR container |
Logical partition (LPAR) | Subset of a single system that contains resources (processors, memory, and input/output devices) An LPAR operates as an independent system and can contain different operating systems such as:
An LPAR can also be inactive. |
Millions of Service Units (MSUs) | A measure of CPU time consumption, calculated as number of CPU seconds used per hour, multiplied by the service units per seconds (SU/sec) coefficient. The SU/sec coefficient depends on the CPC type and model and is normally same for all LPARs on a CPC. |
Monthly License Charges (MLCs) | One of the methods that IBM is using to charge for software products This method is used for the operating system itself and for the most important (and expensive) transaction processing subsystems (for example, CICS, Db2, IMS, and Web Sphere MQ). For more information, see the IBM Z software licensing. |
MLC Product | IBM System z software product using MLC pricing |
MVM | Multiple Version Measurements |
MzNALC | Multiplex System z New Application License Charges |
Rolling 4 hour average (R4HA) | CPU consumption, measured in MSUs R4HA is calculated by RMF using the last 48 5-minute buckets and written into the type 70 record of the z/OS image in which RMF is running. While RMF in each z/OS image records the CPU consumption of all LPARs on the same CPC, the R4HA metric is available only for the host LPAR (the LPAR in which this record is created). |
Sub-Capacity | A group of licensing rules, terms, and conditions for software licenses based on actual CPU resource usage For more information, see the IBM Z software licensing. |
Sub-Capacity Reporting Tool (SCRT) | IBM tool that processes the RMF and SMF records (in particular type 70 and type 89) and produces the Sub-Capacity report This report is used by IBM to calculate the monthly license charge. IBM customers using Sub-Capacity licenses must use SCRT to process data from all LPARs on a CPC for the complete usage month (from 00:00 of day 2 of the calendar month to 24:00 of day 1 of the next calendar month) and send it to IBM. For more information, see the IBM Z software licensing. |
SVC | Single Version Charges |
TFP | Tailored Fit Pricing |
Universal Information Exchange (UIE) | A BMC component that runs on your mainframe system to read and process SMF/RMF and subsystem data collected from target z/OS images UIE can produce two types of output:

VWLC | Variable Workload License Charges |
Workload | A group of work to be tracked, managed, and reported as a unit A workload consumes system resources such as CPU time and I/O operations. Cost Management analyzes only CPU resource consumption. Work performed in the system can be measured and reported by different tools (SMF, RMF). It also can be grouped using different rules. The selected reporting tool or grouping rule determines the workload type. For more information, see Cost-Management-workloads. |
zNALC | IBM System z New Application License Charges |
z/OS | 64-bit operating system for IBM mainframe computers |
z/OS image | An instance of z/OS running in an LPAR or as VM guest z/OS images can run in an LPAR or inside an instance of the z/VM operating system as a guest. |
z/VM | IBM Virtual Machine operating system for mainframe computers |
