DB2 - Problembeschreibung

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

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 ....")
