Numeric or value error: hex to raw conversion error , pls help

Question

I am having problem with a sproc which accepts a Raw parameter.
I have a table called Profile:
CREATE TABLE PROFILES
PROFILEID INTEGER NOT NULL,
USERID INTEGER NOT NULL,
PROFILE RAW(255)
and a sproc named addprofile
CREATE OR REPLACE PROCEDURE addprofile
profile IN RAW,
userName IN VARCHAR2
AS
userId INT;
BEGIN
GetUserIdByName( userName, userId);
INSERT INTO Profiles
( ProfileID,userId , profile )
VALUES ( Profiles_ProfileID_SEQ.NEXTVAL,AddProfile.userId ,
AddProfile.profile );
END;
I am calling the Ent Library's Insert profile method which is part of DbProfileProvider.cs (Security App block). It is trying to persist a serialized profile object into the database.
private void InsertProfile(string userName, byte[] serializedProfile,
Data.Database securityDb, IDbTransaction transaction)
DBCommandWrapper cmd = securityDb.GetStoredProcCommandWrapper
(SPAddProfile);
cmd.AddInParameter("userName", DbType.String, userName);
cmd.AddInParameter("profile", DbType.Binary, serializedProfile);
securityDb.ExecuteNonQuery(cmd, transaction);
I get the following error:
Any suggestion on what needs to be changed to get this working? thanks!

Harsh,
I am not a user of the Enterprise Library so I can not speak to the specifics of that. However, here is a short sample that is based on the information you've provided. Perhaps it will be useful.
Database:
create table profiles
  profileid integer not null,
  userid    integer not null,
  profile   raw(255)
create or replace procedure addprofile
  p_profileid in integer,
  p_userid    in integer,
  p_profile   in raw
as
begin
  insert into
    profiles (profileid, userid, profile)
    values (p_profileid, p_userid, p_profile);
end;
/C# code:
using System;
using System.Data;
using System.Text;
using Oracle.DataAccess.Client;
using Oracle.DataAccess.Types;
namespace HarshTest
  /// <summary>
  /// Summary description for Class1.
  /// </summary>
  class Class1
    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main(string[] args)
      // connect to local db using o/s authentication
      OracleConnection con = new OracleConnection("User ID=/; Pooling=False");
      con.Open();
      // create command object and set properties
      OracleCommand cmd = new OracleCommand();
      cmd.Connection = con;
      cmd.CommandText = "ADDPROFILE";
      cmd.CommandType = CommandType.StoredProcedure;
      // parameter object for profileid
      OracleParameter p_profileid = new OracleParameter();
      p_profileid.OracleDbType = OracleDbType.Int32;
      p_profileid.Value = 1;
      p_profileid.Direction = ParameterDirection.Input;
      // parameter object for userid
      OracleParameter p_userid = new OracleParameter();
      p_userid.OracleDbType = OracleDbType.Int32;
      p_userid.Value = 1;
      p_userid.Direction = ParameterDirection.Input;
      // create a byte array for the raw value
      ASCIIEncoding encoder = new ASCIIEncoding();
      byte[] byteArray = encoder.GetBytes("TestProfile");
      // parameter object for profile
      OracleParameter p_profile = new OracleParameter();
      p_profile.OracleDbType = OracleDbType.Raw;
      p_profile.Value = byteArray;
      p_profile.Direction = ParameterDirection.Input;
      // add parameters to collection
      cmd.Parameters.Add(p_profileid);
      cmd.Parameters.Add(p_userid);
      cmd.Parameters.Add(p_profile);
      // execute the stored procedure
      try
        cmd.ExecuteNonQuery();
      catch (OracleException ex)
        Console.WriteLine(ex.Message);
      // clean up objects
      p_profile.Dispose();
      p_userid.Dispose();
      p_profileid.Dispose();
      cmd.Dispose();
      con.Dispose();
}Maybe the part about creating the byte array is what you are missing...
