This section describes the DASD information acquired from Hiperbatch. These fields are only valid for data sets accessed using Hiperbatch (see SMF14RIN).
If you coded DSECT=YES when calling the IFGSMF14 macro, then it generates a DSECT statement at this point with the DSECT name with "HBTCH" appended to it. For example, if you did not code a label on the IFGSMF14 call, the name of this DSECT will be IFGSMFHBTCH.
| Offsets | Name | Length | Format | Description | |
|---|---|---|---|---|---|
| 0 | 0 | SMFIOREQ | 4 | binary | Number of requests for I/O issued by the access method for this data set for which Hiperbatch attempted to find the requested data in its buffers (see SMFCHITS and SMFPHIOS). |
| 4 | 4 | SMFCHITS | 4 | binary | Number of requests for I/O issued by the access method for this data set satisfied by moving data from Hiperbatch buffers. |
| 8 | 8 | SMFNMWTS | 4 | binary | Number of times Hiperbatch temporarily suspended this requester because another user was already reading some or all of the requested data. |
| 12 | C | SMFPHIOS | 4 | binary | Number of requests for I/O issued by the access method for this data set satisfied by performing DASD I/O. Note that the sum of SMFPHIOS and SMFCHITS should equal SMFIOREQ. |
| 16 | 10 | SMFCIOS | 4 | binary | Number of DASD I/Os (as recorded in SMFPHIOS) for which Hiperbatch copied the data into its buffers. |
