HISAM Reorganization Unload utility (DFSURUL0)
You use the HISAM Unload utility to unload a HISAM database or HIDAM index database.
SHISAM databases are unloaded using the HD Reorganization Unload utility.
If your database uses secondary indexes, you also use the HISAM Unload utility (later in the reorganization process) to perform a variety of other operations associated with secondary indexes.
The following figure shows the input to and output from the HISAM Reorganization Unload utility.
