Status: Geschlossen |
OPTIMIZER CARDINALITY ESTIMATION ERRORS FOR INDEX SCAN OPERATIONS |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 |
| Problembeschreibung: |
The cardinality estimate for index scan operations requiring a
FETCH (IXSCAN, IOA and IXA) might be inaccurate. The situations
when this inaccuracy can occur will vary depending on many
factors. It is more likely to occur if the index's table has
many other indexes, column group statistics, statistical views
or the table is range partitioned. The cardinality of the FETCH
operator corresponding to the index scan operation might also be
inaccurate. |
