Problem IC75331
|
Status: Closed |
STMM DOES NOT TUNE SORTHEAP CORRECTLY FOR INDEX CREATION (INCLUD ING LOAD,REORG) |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
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 Summary: |
****************************************************************
* USERS AFFECTED: *
* Systems running with STMM enabled to tune SORTHEAP *

* PROBLEM DESCRIPTION: *
* See Error Description *
****************************************************************
* RECOMMENDATION: *
* upgrade to Version 9.7, Fix Pack 5 *
**************************************************************** |
| 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. |
