More about zNALC pricing

System z® New Application License Charges (zNALC) pricing applies to the z/OS® base feature and z/OS priced features. zNALC is available for z/OS on LPARs dedicated to qualified applications, among other requirements. See System z New Application License Charges (zNALC) for more details.

Whenever SCRT encounters SMF data from zNALC LPARs (for example, LPARs whose names have the format ZNALxxxx), SCRT reports the z/OS MSUs in one of two formats. These zNALC formats are shown in the following sections of the sub-capacity report:
  • Product Summary Information
  • Product Max Contributors
  • Product Grid Snapshot
  • Defined Capacity Value Used

When the SMF data is from a CPC where all of the z/OS LPARs are zNALC LPARs, SCRT reports all of the z/OS values as zNALC values and lists z/OS (zNALC) as the name in the MLC Product Name column of the sub-capacity report. In this case, IBM charges zNALC pricing for all of the z/OS use on the CPC. See Figure 1.

When the SMF data is from a CPC with both traditional z/OS LPARs (for example, LPARs whose names do not have the format ZNALxxxx), and zNALC LPARs, SCRT reports three values for z/OS:
  • z/OS – this value represents the MSU values for z/OS running in all LPARs on the CPC. This value is used when assigning capacity to the z/OS based IPLA sub-capacity products running on this CPC.
  • z/OS (Traditional) – this value represents the MSU value charged against traditional z/OS use.
  • z/OS (zNALC) – this value is used to determine what MSU value is charged against zNALC use. IBM® uses the zNALC value reported on the SCRT, whenever the zNALC value is smaller than the difference between the z/OS value and the z/OS (Traditional) value.

When the difference between the z/OS value and the z/OS (Traditional) value is smaller than the zNALC value, then the difference is used, unless the difference is less than three MSUs. See z Systems New Application License Charges for the rules that govern the case for when the resulting zNALC value is less than three MSUs.
