A DBUTLTY REFGROUP report allows you to determine the current data organization in a database by accessing each data row within a specified table by reference groupings. You use a reference group parameter (REFGROUP=) to specify the number of data blocks that are to be considered as a group. For information, see REFGROUP= in the list of Required Keywords. REFGROUPs are used to analyze (report) and reorganize (using the OLREORG function for online database reorganization) data rows on a reference group by reference group basis. Access for the REFGROUP report option is through the Multi-User Facility. For information on the OLREORG function, see OLREORG (Reorganize a Database Online).
You can select two types of REFGROUP reports, summary reports (TYPE=S) and detail reports (TYPE=D or TYPE=K). For information on specifying TYPE=, see TYPE= in the list of Required Keywords.
