Problem IC75268
|
Status: Geschlossen |
STMM DOES NOT TUNE SORTHEAP CORRECTLY FOR INDEX CREATION (INCLUDING LOAD,REORG) |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problembeschreibung: |
Due to a logic error, STMM does not cost SORT operations for
index creation during the initial "insert" phase.
As a result, SORTHEAP may not be tuned appropriately.
This impacts longer index creations which may benefit from
higher SORTHEAP settings.
Activities impacted include LOAD, REORG, CREATE INDEX. |
| Problem-Zusammenfassung: |
****************************************************************
* USERS AFFECTED: *
* Systems configured with STMM tuning SORTHEAP *
****************************************************************
* PROBLEM DESCRIPTION: *
* See Error Description *
****************************************************************
* RECOMMENDATION: *
* Upgrade to DB2 Version 9.5 Fix Pack 8 OR configure SORTHEAP *
* (and SHEAPTHRES_SHR) to a fixed value *
**************************************************************** |
| Local-Fix: |
Manually tune SORTHEAP, SHEAPTHRES_SHR to desired values if the
database is configured for AUTOMATIC Sort tuning.
It is possible to do this dynamically with a database
connection, and return to AUTOMATIC after the activity involving
index creation is complete. |
