Subtype 34 — Processor capacity change

A subtype 34 record is generated when a processor capacity change occurs, which is triggered by an ENF61 signal, qualified by WLMENF12 along with a change in processor capacity.

Processor capacity change section

This record is generated when a processor capacity change occurs.

Offsets Name Length Format Description
0 0 SMF90T34_Capacity_Change _Time 8 binary Time when the capacity was last changed.
8 8 SMF90T34_RQSVSUS 4 binary Current service unit factor (SU factor) from RQSVSUS.
12 C SMF90T34_RCTPCPUA _Actual 4 binary Physical CPU adjustment factor (for example, adjustment factor for converting CPU time to equivalent service in basic-mode with all processors online). Based on model capacity rating.
16 10 SMF90T34_RCTPCPUA _Nominal 4 binary Physical CPU adjustment factor (for example, adjustment factor for converting CPU time to equivalent service in basic-mode with all processors online). Based on nominal model capacity rating.
20 14 SMF90T34_RCTPCPUA _scaling_factor 4 binary Scaling factor for RCTPCPUA_actual and RCTPCPUA_nominal.
24 18 SMF90T34_Capacity_Adjustment _ Ind 1 binary When:
0
The indication is not reported.
1-99
Some amount of reduction is indicated.
100
The machine is operating in normal capacity.
Primary CPUs and all secondary-type CPUs are similarly affected.
25 19 SMF90T34_Capacity_Change _Reason 1 binary Indicates the reason that is associated with the present value contained in SMF90T34_Capacity_Adjustment_ Ind. The bit values of this field correspond to those described in RMCTZ_Capacity_Adjustment_Indication of the IRARMCTZ mapping macro. (See MVS™ Data Areas).
26 1A SMF90T34_Flags 1 binary Error flags.
Bit
Meaning when set
0
SMF90T34_RQSVSUS_ErrMeaning: When on, indicates that an error occurred while collecting the value from RQSVSUS.
1
SMF90T34_Capacity_Data_errMeaning: When on, indicates that an error occurred while collecting the processor capacity data.
2
SMF90T34_PCD_Rsvd_ExistsMeaning: When on, indicates records generated on systems running z/OS® V1R7 through z/OS V1R9. When off, indicates records generated on systems running z/OS V1R10 and later.
28 1C SMF90T34_RMCTADJN_Nominal 4 binary Nominal CPU rate adjustment
