Utiliser <Oracle.manageddataaccess.client> élément dans web.config, il est nécessaire de l'enregistrer avec <section> ou <sectionGroup> élément à l'intérieur <configSections>. Vous devez décommenter cette partie car dans votre exemple, elle commentait toujours:

<section name="Oracle.manageddataaccess.client" type="OracleInternal.Common.ODPMSectionHandler, Oracle.ManagedDataAccess, Version=4.122.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />

Si la mise en commentaire de cette ligne ne fonctionne toujours pas, remplacez-la par <sectionGroup> élément:

<sectionGroup name="Oracle.manageddataaccess.client" type="OracleInternal.Common.ODPMSectionHandler, Oracle.ManagedDataAccess, Version=4.122.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />

Assurez-vous également que ODP Managed Data Access est déjà enregistré en tant que référence d'assembly dans votre projet et/ou GAC (Global Assembly Cache).

Je trouve plus facile de gérer moi-même les chaînes de connexion, au lieu d'accepter la modification par Oracle du fichier web.config.

Mettez en commentaire <Oracle.manageddataaccess.client> Et l'entrée <configSections> Correspondante qu'Oracle insère.

À la place, j'utilise la section Microsoft <connectionStrings> Accessible par ConfigurationManager

<connectionStrings> <clear/> <add name="DB_CONN_STRING" connectionString="Data Source=servername:1521/dbinstancename;User ID=user;Password=pwd;"/> </connectionStrings>

Puis en code, créez ma connexion avec:

using System.Configuration;
using Oracle.ManagedDataAccess.Client;

string conString = ConfigurationManager.ConnectionStrings["DB_CONN_STRING"].ConnectionString;

OracleConnection myConnection = new OracleConnection(conString);
myConnection.Open();

Au lieu de modifier votre web.config fichier manuellement, vous pouvez également utiliser l'application OraProvCfg.exe. Exécutez le script comme ci-dessous (choisissez la version qui est installée sur votre système):

set Oracle_x64=c:\Oracle\product\12.1\Client_x64\odp.net
set Oracle_x86=c:\Oracle\product\12.1\Client_x86\odp.net
set OraProvCfg_x64=%Oracle_x64%\bin\4\OraProvCfg.exe
set OraProvCfg_x86=%Oracle_x86%\bin\4\OraProvCfg.exe

set TNS_ADMIN=C:\Oracle\network\admin
set CONFIGFILE_PATH=.../web.config


REM Delete configuration, if needed
"OraProvCfg_x64" /action:unconfig /product:odpm /frameworkversion:v4.0.30319 /configfile:%$CONFIGFILE_PATH%
"OraProvCfg_x86" /action:unconfig /product:odpm /frameworkversion:v4.0.30319 /configfile:%$CONFIGFILE_PATH%



REM Add configuration
"%OraProvCfg_x64%" /action:gac /providerpath:%Oracle_x64%\managed\common\Oracle.ManagedDataAccess.dll
"%OraProvCfg_x64%" /action:gac /providerpath:%Oracle_x64%\managed\PublisherPolicy\4\Policy.4.121.Oracle.ManagedDataAccess.dll
"%OraProvCfg_x64%" /action:gac /providerpath:%Oracle_x64%\managed\PublisherPolicy\4\Policy.4.122.Oracle.ManagedDataAccess.dll

"%OraProvCfg_x64%" /action:config /configfile:%$CONFIGFILE_PATH% /product:odpm /frameworkversion:v4.0.30319 /providerpath:%Oracle_x64%\managed\common\Oracle.ManagedDataAccess.dll /set:settings\TNS_ADMIN:%TNS_ADMIN%
"%OraProvCfg_x86%" /action:config /configfile:%$CONFIGFILE_PATH% /product:odpm /frameworkversion:v4.0.30319 /providerpath:%Oracle_x86%\managed\common\Oracle.ManagedDataAccess.dll /set:settings\TNS_ADMIN:%TNS_ADMIN%

Si vous sautez /configfile:... puis l'application modifie le global machine.config fichier. Vous devrez peut-être également configurer /product:aspnet, courir OraProvCfg.exe et vérifiez l'impression.
