The table below describes each field in the Expanded Storage Movement section of the Storage Management Report.
Field | Description | |
|---|---|---|
HIGH UIC - MIN | minimum high Unreferenced Interval Count (UIC) in seconds (time that a page of central storage frames has not been referenced) 1 | |
HIGH UIC - MAX | maximum high Unreferenced Interval Count (UIC) in seconds (time that a page of central storage frames has not been referenced) 1 | |
HIGH UIC - AVG | average high Unreferenced Interval Count (UIC) in seconds (time that a page of central storage frames has not been referenced) 1 | |
RATES - FROM CENTRAL | the rate, in pages per second, VIO, hiperspace, and shared pages were moved from central storage to expanded storage 2 | |
RATES - TO CENTRAL | the rate, in pages per second, VIO, hiperspace, and shared pages were moved from expanded storage to central storage 2 | |
RATES - TO AUXILIARY | the rate, in pages per second, VIO, hiperspace, and shared pages were moved from expanded storage to auxiliary storage 2 | |
PERCENT OF TOTAL - FROM CENTRAL | percentage of the total page movements for this row’s area that were movements from central storage to expanded storage 2 | |
PERCENT OF TOTAL - TO CENTRAL | percentage of the total page movements for this row’s area that were movements from expanded storage to central storage 2 | |

STORAGE REQUEST RATES | GETMAIN REQUESTS | GETMAIN request rate |
FRAMES BACKED | rate of frames backed during issued GETMAIN requests | |
FIX REQUESTS < 2 GB | rate of fix requests issued for storage below 2 GB (address space only) | |
FRAMES < 2 GB | rate of frames requested to be fixed for storage below 2 GB (address space only) | |

1 On z/OS systems 1.8 and later, the range is 1 to 65535; on z/OS systems 1.7 and earlier, the range is 1 to 2540.
2 The VIO, HIPERSPACE, and SHARED values are subsets of the TOTAL values.
3 A VIO page frame is allocated to a VIO address space, a HIPERSPACE frame is allocated to a HIPERSPACE, and a SHARED page frame is allocated to a shared address space.
