RUNSTATS
Gathers summary information about the characteristics of the data in table spaces and indexes. This information is recorded in the DB2 catalog, and is used by DB2 to select access paths to data during the bind process. It is available to the database administrator for evaluating database design, and determining when table spaces or indexes should be reorganized
REORG
Reorganized a table space to improve access performance and reclaim fragmented space. In addition, the utility can reorganize a single partition of either a partitioned index ora partitioned table space. If you specify REORG UNLOAD ONLY or REORG UNLOAD PAUSE, the REORG utility unloads data in a format acceptable to the LOAD utility of the same DB2 table space.
