How big is the data set?
The precise size of a data set will depend on the particular DBGEN command line options that are used to create it. For example, if the flat files that make up a data set use fixed length fields, the resulting files will be larger than those generated using variable length data. As a rule of thumb, the data set will consist of 1.2 GB of flat files at the 1 GB scale factor, with the lineitem table being the single largest file, at approximately 850MB per SF.
