Distribution of Free Space report
The Distribution of Free Space report provides the following information:
Field | Description |
|---|---|
DSG | The data set group number for the row of information. |
FREE SPACE RANGE | The lower and upper limits of the free space for this row in the report. The last row for each data set group always has a zero lower limit and an upper limit of one byte less than the smallest segment in the data set group. This last row shows the number of blocks that do not have enough free space to hold the smallest segment. The top row for each data set group always has a lower limit equal to the length of the largest segment in the data set group. The number of blocks shown on the top row should correspond to the number of blocks the bitmap shows as having free space. The rows between the top and bottom rows (if any) have lower and upper limits based on the sizes of the segments in that DSG. The numbers shown in these rows should help you determine how many blocks have enough free space to hold a particular segment type. |
NUMBER BLOCKS | The number of blocks containing a free space element that falls within the free space range. |
PCT OF TOTAL | The percentage of the total blocks that falls within the limits shown. |
CUMULATIVE NBR BLOCKS | The total number of blocks that can hold segments of that size for any given free space interval. |
CUMULATIVE PCT TOTAL | The percentage of blocks that can hold a segment whose size fits in the free space interval. |
