A Control Area is a contiguous area of DASD that ranges in size from one track to one cylinder. Displays the number of Control Intervals in each Control Area.
Amount of space allocated to the VSAM file that does not contain a Control Interval.
The number of bytes of space being managed by the VSAM file.
The highest byte number within a used Control Interval.
Free space as a percentage of the high used RB.
The minimum amount of data that is transferred together which is at least one Control Interval.
Number of physical records in each DASD track.
Number of tracks in each Control Area.
This section contains counts of the number of data records and the number of times data records have been inserted, deleted, updated, and retrieved since the initial load of the VSAM file. The following counts are displayed:
The total number of records actually in the data or index component. This statistic is not maintained when the data set is processed in control interval mode.
The number of records that have been deleted from the data or index component.
For a key-sequenced data set, the number of records that have been inserted into the data component before the last record; records originally loaded and records added to the end are not included in this statistic. For relative record data sets, it is the number of records inserted into available slots; the number of records originally loaded are included in this statistic.
The number of records that have been retrieved for update and rewritten. This value does not reflect those records that were deleted, but a record that is updated and deleted is counted in the update statistics.
The number of records that have been retrieved from the data or index component, whether for update or not for update.
