how to insert into database from stored procedure in log4net?

Question

I have to log thread context properties like this:

        string logFilePath = AppDomain.CurrentDomain.BaseDirectory + "log4netconfig.xml";
        FileInfo finfo = new FileInfo(logFilePath);
        log4net.Config.XmlConfigurator.ConfigureAndWatch(finfo);
        ILog logger = LogManager.GetLogger("Exception.Logging");

        log4net.ThreadContext.Properties["MESSAGE"] = exception.Message;
        log4net.ThreadContext.Properties["MODULE"] = "module1";
        log4net.ThreadContext.Properties["COMPONENT"] = "component1";
        logger.Debug("test");

and the configuration file is:

<configuration>
  <configSections>
    <section  name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,Log4net"/>
  </configSections>

  <log4net>
    <logger name="Exception.Logging" level="Debug">
      <appender-ref ref="AdoNetAppender"/>
    </logger>
    <appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
      <connectionString value="Data Source=xe;User ID=test;Password=test;" />
      <connectionType value="System.Data.OracleClient.OracleConnection, System.Data.OracleClient, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
      <bufferSize value="10000"/>
      <commandText value="Log_Exception_Pkg.Insert_Log" />
      <commandType value="StoredProcedure" />

      <parameter>
        <parameterName value="@p_Error_Message" />
        <dbType value="String" />
        <size value="255" />
        <layout type="log4net.Layout.PatternLayout">
          <conversionPattern value="%property{MESSAGE}"/>
        </layout>
      </parameter>

      <parameter>
        <parameterName value="@p_Module" />
        <dbType value="String" />
        <size value="225" />
        <layout type="log4net.Layout.PatternLayout">
          <conversionPattern value="%property{MODULE}"/>
        </layout>
      </parameter>

      <parameter>
        <parameterName value="@p_Component" />
        <dbType value="String" />
        <size value="225" />
        <layout type="log4net.Layout.PatternLayout">
          <conversionPattern value="%property{COMPONENT}"/>
        </layout>
      </parameter>
    </appender>
  </log4net>
</configuration>

But its not inserting them in the database. How can I get that to work?
