    From the SMF LOGSTREAM we dump using IFASMFL to regular GDGs

    this runs quickly.


    once a day we copy the GDGs created during the last 24 hours to tape files and some other disk files using IFASMFDP with the following cards. This is the past that runs too long.

    There is no signature validation involved.

    We would like to get a better idea of how your in stallion processes the SMF data. Assuming you use SMF log stream recording, since that is the recording medium where SMF stores the digital signatures, do you pass all of the signed data to IFASMFDP for validation, or are you simply dumping it to long term storage?
