Problem IT22968
|
Status: Closed |
RUNSTATS with index sampling can produce INCORRECT NLEAF OF PARTITIONED INDEX FOR LARGE RANGE PARTITIONED TABLE |
| product: |
DB2 FOR LUW / DB2FORLUW / B10 - DB2 |
| Problem description: |
When executing Runstats on a range partitioned table with one or
more partitioned indexes, the index stats can be incorrect when
the index sampling option is used.
This issue mostly occurs for large number of rows in a
partitioned table.
As a result, Runstats might calculate an incorrect table Card. |

| Local Fix: |
Don't use the INDEXSAMPLE option or use an index sampling rate
less than the table sampling rate. The latter will only ensure
the cardinality statistic is calculated correctly. |
