Hi All,

I am trying to implement oracle UDT in ASP.NET

i am facing the below error

"Section or group name 'oracle.dataaccess.client' is already defined. Updates to this may only occur at the configuration level where it is defined."

the Configuration i am using is

XML

<?xml version="1.0"?>

<configuration>
  <configSections>
    <sectionGroup name="oracle.dataaccess.client"
                  type="Oracle.DataAccess.Client.OracleSectionGroup, Oracle.DataAccess, Version=2.111.6.20, Culture=neutral, PublicKeyToken=89b483f429c47342">
      <section name="settings"
               type="Oracle.DataAccess.Client.SettingsSection, Oracle.DataAccess, Version=2.111.6.20, Culture=neutral, PublicKeyToken=89b483f429c47342" />
      <section name="udtCustomTypeMappings"
               type="Oracle.DataAccess.Client.UdtCustomTypeMappingsSection, Oracle.DataAccess, Version=2.111.6.20, Culture=neutral, PublicKeyToken=89b483f429c47342" />
    </sectionGroup>


    <oracle.dataaccess.client>
      <settings>
        <add name="Customer_Type" value="udtMapping factoryName='Customer_TypeFactory,  Customer_Type, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' typeName='CUSTOMER_OBJECT' schemaName='scott'    dataSource='oracle'" />
        <add name="Customer_Table" value="udtMapping factoryName='Customer_TableFactory,  Customer_Table, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' typeName='CUSTOMER_TABLE' schemaName='scott'  dataSource='oracle'" />
      </settings>
    </oracle.dataaccess.client>
  </configSections>
  <appSettings/>
  <connectionStrings/>


</configuration>

Solution 1

My guess is that you'll find the 'oracle.dataaccess.client' sectionGroup in the
[Windows directory]\Microsoft.NET\Framework\[Framework Version]\CONFIG\machine.config file.

Adding it to your web.config file causes it to be defined twice.

You can read about the asp.net configuration files here:
