|
Status: Geschlossen |
USING MON, MONTH, DAY, DY IN THE FORMAT STRING IN FUNCTION TO_TIMESTAMP OR TIMESTAMP_FORMAT CAN AFFECT PERFORMANCE OF QUERY |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problembeschreibung: |
Using MON, MONTH, DAY, Dy in the format string in TO_TIMESTAMP
or TIMESTAMP_FORMAT can affect the performance of the query due
to excessive calls to sqlnls_fmblk_callback or
sqlnls_gmblk_callback driving the contention on the memory latch
higher thus affecting the overall performance of the query.
This issue does not happen in DB2 v95 or lower. |
