Problem IC68642
|
Status: Geschlossen |
CALL OF A PROCEDURE OR REFERENCE TO A FUNCTION DEFINED WITHIN A MODULE WILL CAUSE A RECOMPILE RATHER THAN A PACKAGE CACHE HIT. |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problembeschreibung: |
If a user has been granted execute on a module, each CALL of a
procedure within the module or reference to a FUNCTION within
the module will
cause a recompile of the CALL statement,
Aside from the extra compiles this causes, this may result in a
series of valid entries in the package cache (one per statement
with a MODULE procedure or funtion reference), and eventually
searching these entries can cause severe performance problems |
| Problem-Zusammenfassung: |
****************************************************************
* USERS AFFECTED: *
* users of MODULES or SQL/PL PACKAGES *
****************************************************************
* PROBLEM DESCRIPTION: *
* Performance impacted when module procedures/functions are *
* used in dynamic SQL. *
****************************************************************
* RECOMMENDATION: *
* Upgrade to V97 fixpack 3 *
**************************************************************** |
| Local-Fix: |
Granting the user EXECUTE on procedures and functions while
unnecessary for authorization can avoid the extra compiles.
Since execute privilege cannot be granted directly on a
procedure or function within a module, this would have to be
done using the wildcard specification ("GRANT EXECUTE ON
PROCEDURE/FUNCTION <SCHEMA>.* to ....") |
