SHEAPTHRES_SHR RECOMMENDATION IS MISSING FROM THE OUTPUT WHEN RUNNING THE CONFIGURATION ADVISOR |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problembeschreibung: |
The database configuration parameter, SHEAPTHRES_SHR, can be
automatically configured by the Configuration Advisor via the
AUTOCONFIGURE command. However, the recommendation for
SHEAPTHRES_SHR is not shown in the output of the AUTOCONFIGURE
command. In the case where AUTOCONFIGURE command is called with
the APPLY option, the update on SHEAPTHRES_SHR to the
recommended value actually takes place.
Here's a sample output from running AUTOCONFIGURE on the CLP:

| Problem-Zusammenfassung: |
****************************************************************
* USERS AFFECTED: *
* All DB2 Version 9.5 Fix Pack 5 servers on Linux, Unix, and *
* Windows platforms issuing the AUTOCONFIGURE command. *
****************************************************************
* PROBLEM DESCRIPTION: *
* The AUTOCONFIGURE command is only expecting "n" DB CFG *
* parameters, but the actual number of parameters is "n+1". *
* SHEAPTHRES_SHR is the last parameter in the structure, thus, *
* it's missed from the output. *
****************************************************************
* RECOMMENDATION: *
* Upgrade to DB2 Version 9.5 Fix Pack 5 or see "Local Fix". *
**************************************************************** |
| Local-Fix: |
It's advised to always leave SHEAPTHRES_SHR set to its default
which is AUTOMATIC. |
