Navigation

For additional information about
  • a report interval, move the cursor to the line you want and press F11 (Zoom). (Each date/time displayed reflects the end of an interval.)
  • related topics, select one of the options at the top of the panel.
  • other topics, use the PF keys.

Fields

Collection Interval
The time interval specified for the collection of near-term history data. This unit of time was specified when the Near-Term History Data Collector was started.
Start
The start time of the first interval in this display.
Report Interval
This field determines the report interval. It is set on the Near-Term History Report Option panel.
Combine Level
This field reflects the selected combine level. If Combine Level is NONE, the report interval is the same as the collection interval. Possible values:
HOURLY
Data will be reported in hourly intervals.
NONE
Data will be reported in the time unit specified by the collection interval.
End
The end time of the last interval in this display.
Interval
Provides the date and time that mark the end of the report interval.
High Water Open DS
Maximum number of data sets open at any given time.
Current Open DS
The current number of open data sets.
Not-in-use DS Request
The number of requests to open a data set that was on the Deferred Close queue. When this occurs, a physical data set Open is not necessary.
Not-in-use DS Closed
Number of not-in-use data sets that were closed because the total number of open data sets reached the Deferred Close threshold. The Deferred Close threshold is based on the smaller of the values of DSMAX or the MVS DD limit.
DS Conv to Read-only
Number of infrequently updated data sets converted from a read-write state to a read-only state (pseudo-close). The SYSLGRNG entry is closed at this time.
