The dflt_history_columns parameter adds more non-DMSII columns (user columns) to all history tables in the client database. By default, history tables are created with three non-DMSII columns. The dflt_history_columns parameter is intended to simplify user scripts at sites where the same non-DMSII columns (user columns) are added to all (or most) history tables. When you use this parameter to add user columns to history tables, the same kind of non-DMSII columns are added to all history tables. If you do not want to add the same columns to all history tables, you must generate the columns using a user script or set active = 0 for the unwanted columns.
