Sub-Capacity for z/OS
When you are running z/OS in 64-bit mode and are no longer running OS/390 on your System z server, you have the option to pay the charges for your eligible software on a sub-capacity basis. The Sub-Capacity Reporting Tool (SCRT) is the program which processes SMF 70 and SMF 89 records created by z/OS to produce a report showing LPAR utilization figures which are used to set the software charges.
Sub-capacity pricing is based on the four-hour rolling average utilization of the z/OS LPARs observed within a one month reporting period. The reporting periods run from 00:00 on the second calendar day of the month through midnight (23:59) on the first calendar day of the following month.
Please see the Sub-Capacity for z/TPF page for additional information if you are also running z/TPF LPARs and need to include the z/TPF data in your SCRT report.
Please see the Sub-Capacity for z/VSE page for additional information if you are also running z/VSE LPARs and need to include the z/TPF data in your SCRT report.
