Are you talking about creating an extract file from SMF? Are you talking about creating the data set SMF writes interval data into? Are you talking about creating the daily accumulation files used for SMF data? All three are perfectly valid, but require different creation JCL.
And why are you asking this? If you are authorized to do this, then you should already have knowledge of what is required -- and the fact that there is much more involved than just defining some data sets. If you're not authorized to do this, sites really don't like people doing things to the SMF files and have been known to take action up to and including termination of employees who do so.
