DSNTSMFD
The DSNTSMFD program decompresses Db2 trace records that were compressed when they were written to SMF.
Authorization required
You need no special authorization is needed to run DSNTSMFD.
Input
Input to the DSNTSMFD program is one or more data sets that contain Db2 trace records in standard SMF format. The data sets can contain SMF records of all types, but DSNTSMFD decompresses only SMF type 100, 101, or 102 records.
The input data sets are allocated to DD name SMFINDD.
Output
The DSNTSMFD program produces the following output:
- A data set that contains all of the Db2
trace records that are in the input data set. SMF type 100, 101, or 102 records are decompressed in
the output data set.
If DSNTSMFD cannot decompress the SMF type 100, 101, or 102 records, DSNTSMFD writes the compressed records to the output data set and issues a warning.
This output data set is allocated to DD name SMFOUTDD.
- A data set that contains details about decompression, such as the number of records that were
decompressed, and the amount of space that was saved through compression.
This output data set is allocated to DD name SYSPRINT.
