DB2 - Problembeschreibung

Problem IC78314 Status: Geschlossen

DB2NMPCFG CAN CREATE DUPLICATE ENTRIES WITH SAME INVARIANT NAME IN
DBPROVIDERFACTORIES SECTION OF MACHINE.CONFIG

Produkt:
DB2 FOR LUW / DB2FORLUW / 970 - DB2
Problembeschreibung:
db2nmpcfg.exe fails to remove entries with the same invariant 
name as the ones being added if the assembly version is 
different.  This results in an invalid machine.config since the 
invariant name must be unique. db2nmpcfg.exe should remove all 
DbProviderFactories entries with the same invariant regardless 
of other attribute values. 
 
An exception similar to the following is encountered when using 
DbProviderFactories with a mis-configured machine.config file: 
 
           System.Configuration.ConfigurationErrorsException: An 
error occurred creating the configuration section handler for 
system.data: Column 'InvariantName' is constrained to be unique. 
 Value 'IBM.Data.DB2' is already present. 
(c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Config\machine.co 
nfig 
line 537) ---> System.Data.ConstraintException: Column 
'InvariantName' is constrained to be unique.  Value 
'IBM.Data.DB2' is already present.
