JCL to Clear SMF Datasets

Here’s a simple example of a batch job to clear the content of your SMF datasets:

//SMFDP    EXEC PGM=IFASMFDP
//INDD1    DD   DISP=SHR,DSN=SYS1.MAN1
//INDD2    DD   DISP=SHR,DSN=SYS1.MAN2
//INDD3    DD   DISP=SHR,DSN=SYS1.MAN3
//SYSPRINT DD   SYSOUT=*
//SYSIN    DD   *
       INDD(INDD1,OPTIONS(CLEAR))
       INDD(INDD2,OPTIONS(CLEAR))
       INDD(INDD3,OPTIONS(CLEAR))

Explanation:

INDDx – are the DD cards that specify the SMF datasets. SYS1.MANx are the examples in the JCL above.
