Provide an estimate (plus or minus ten percent) of the amount of disk space required for the table and index data in a given data area. Used during initial setup or when migrating from another database.

In online mode, the utility also checks the Oracle database to determine how much space you have available in your table space.

In online mode, the utility reads the Lawson dictionary to find the initial and incremental record counts for each table and index listed in the dictionary. From the record counts and row sizes, the utility estimates the actual physical size required.
