Partition Stats report
The Partition Stats report is generated if the database uses the IMS/ESA Partition Support Product.
This report is generated instead of the Dataset Statistics report. The Partition Stats report provides the following information:
Field | Description |
|---|---|
PRT | The partition number. |
DDNAME | The ddname for the data set, obtained from the DBD. |
BLOCK SIZE | The data set’s block/CI size. |
RECORD SIZE | The data set’s logical record length. |
DSNAME | The data set name used in the JCL. |
FBFF | The free block frequency factor found in the DBD. |
FSPF | The free space percentage factor (FSPF) found in the DBD. |
FSPF BYTES | The number of bytes of space the FSPF represents. |
SMALL SEGSZE | The number of bytes of space required to hold the smallest segment in this data set group, including prefix and data. |
LARGE SEGSZE | The number of bytes of space required to hold the largest segment in this data set group, including prefix and data. |
TOTAL BLOCKS | The highest block/CI written in the data set. If this is a VSAM data set, it includes CI 0. This number can help determine subsequent space allocation. |
