How to transfer SMF data from oneSMF data set to another.
A. I SMF
B. V SMF
C. T SMF
D. None
Answer
A. I SMF
Explanation
To transfer SMF (System Management Facilities) data from one SMF data set to another in z/OS, you use the I SMF command in JCL.
The I SMF command initializes SMF recording by transferring previously recorded SMF data from the SMF data set defined in SYS1.PARMLIB(SMFPRMxx) to another SMF data set that will become the active SMF recording data set. This allows SMF data to be recorded in the new data set while the previous data set is dumped for analysis or backup purposes.
The V SMF command only displays SMF data but does not transfer it between data sets. The T SMF command terminates SMF recording. Therefore, I SMF is the only valid command out of the choices provided to transfer SMF data from one data set to another in z/OS systems.
In summary, always use the I SMF command in your JCL to properly transfer previously recorded SMF data to a new SMF recording data set. This is an essential step to manage SMF data sets and enable ongoing collection of critical SMF metrics in z/OS mainframe environments.
