CALL OF A PROCEDURE OR REFERENCE TO A FUNCTION DEFINED WITHIN A MODULE WILL | |
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 ....") | |
