Problem IC95475
|
Status: Closed |
IN RARE TIMING SCENARIO, LOAD PERFORMANCE WITH LOB VALUES MAY DEGRADE |
| product: |
DB2 FOR LUW / DB2FORLUW / A50 - DB2 |
| Problem description: |
When Loading a large data set, and the target table has a LOB
(CLOB/BLOB/LF) column, and the LOB column is not inlined (or the
LOB column is inlined but there are lots of lob values which are
too large to inline), the performance of the Load utility may
decline significantly. This is caused by a rare timing scenario
where, for each record processed by Load, it will search the
entire lob object for free space instead of using an available
hint. |
