Overflow Accesses

The number of times that accesses to overflowed rows in this table were required. An overflowed row is an updated row that no longer fits on the data page where it was originally written. The overflow is usually the result of an update to a VARCHAR value or of an ALTER TABLE statement that adds columns to the table.

Overflowed rows indicate that data fragmentation has occurred. If the number of accesses to overflowed rows is high, consider reorganizing the table using the DB2 REORG utility to clean up the fragmentation.
