The Tune DBS step automatically updates certain settings in the dbscontrol.gdo based on the family model of your system. This step runs automatically with no user intervention. If the platform family model of your system requires specific dbscontrol settings, this step performs a tpareset to shut down the database, update the appropriate settings, and then restart the database.
Not all Teradata platforms require dbscontrol updates. The PUT sequencer log for this step shows any specific values being set for your system. For further information about the settings required on platforms, consult the Global Support Center.
