Data sets that DSNTSMFD uses
The DSNTSMFD utility uses a number of data sets during its operation.
The following table lists the data sets that DSNTSMFD uses.
| Data set type | DD name | Description | Required? |
|---|---|---|---|
| Input | SMFINDD | One or more data sets that contain Db2 trace records in standard SMF format. The data sets are sequential data sets that contain the output of an SMF dump utility, such as IFASMFDP. | Yes |
| Output | SMFOUTDD | A data set into which DSNTSMFD writes the trace records that are in the input data sets, with SMF type 100, 101, and 102 records decompressed. This data set must have the same data set characteristics as the input data set, but must be larger than the total size of all input data sets, to accommodate the decompressed records. | Yes |
| Output | SYSPRINT | A data set into which DSNTSMFD writes a report about SMF record decompression, such as the number of records that were decompressed, and the amount of space that was saved through compression. | Yes |
