If you are implementing the recommended data set placements during your ServerPac or SystemPac (dump-by-data-set format) installation, once you have configured your system data sets you do not update your SMP/E DDDEFs to reflect the configuration. The DDDEFs will correctly identify the data sets for the configuration you have chosen.

If you are implementing the recommended data set placements outside of a ServerPac or SystemPac (dump-by-data-set format) installation, update your DDDEFs to identify the appropriate volumes. You can use the SMP/E ZONEEDIT command. If your data sets are cataloged, you will not have to update the UNIT and VOLUME. You should verify that the data sets you moved are correct in their DDDEFs.The CustomPac Installation Dialog allows DDDEF to be defined for user-defined data sets. The installation job will define the DDDEF for user-defined data sets as mentioned in the configuration.
