Examples of DSNTSMFD invocation

Use the DSNTSMFD invocation examples as models for generating your own DSNTSMFD output.

Example: Decompression of Db2 trace records

Suppose that an SMF data set contains compressed Db2 trace records of SMF type 100, 101, or 102. You have dumped the data into sequential data set DSN1310.SMFDATA. You want to write all of the SMF data to data set DSN1310.SMFOUT, and you want any compressed SMF type 100, 101, or 102 records to be decompressed in DSN1310.SMFOUT.

The JCL for the step that executes DSNTSMFD looks like this:

//RUNSMFD  EXEC PGM=DSNTSMFD              
//SYSPRINT  DD SYSOUT=*                   
//SYSUDUMP  DD SYSOUT=*                   
//SMFINDD   DD DSN=DSN1310.SMFDATA,        
//             DISP=SHR                   
//SMFOUTDD  DD DSN=DSN1310.SMFOUT,         
//             LIKE=DSN1310.SMFDATA,       
//             DISP=(,CATLG),             
//             UNIT=SYSDA,                
//             SPACE=(TRK,(1200,200))

The output looks like this:
