Returning multiple refcursor in Oracle through enterprise library 4.1

I found this simple code snippet for how to retrieve multiple RefCursor values in Oracle through Enterprise Library 4.1

object[] parameters = new object[3];
DataSet ds = new DataSet();
Database db = DatabaseFactory.CreateDatabase();
DBCommandWrapper cw = db.GetStoredProcCommandWrapper("mypackage.mypackagename", parameters);
db.LoadDataSet(cw, ds, new string[] {"RefCur1", "RefCur2", "RefCur3"});

Exception handling in Enterpirse Library 4.1

After goggling lot very patiently,I find something all irrelevant to my task.
Finally i corrected by watching carefully on my system thrown exceptions.

Add this below line between ConfigSection of tag.

section name="exceptionHandling" type="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Configuration.ExceptionHandlingSettings, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling" /

Paste this line somewhere but between configuration tag
exceptionHandling
exceptionPolicies
add name="Global Policy"
exceptionTypes
add name="Exception"
type="System.Exception,
mscorlib, Version=2.0.0.0,
Culture=neutral,
PublicKeyToken=b77a5c561934e089"
postHandlingAction="None"

/add
/exceptionTypes
/add
/exceptionPolicies
/exceptionHandling

My source code for catching the exception is

try
{
int a = 0;
int b = 1;
int result = b / a;
Response.Write(result.ToString());

}
catch (System.Exception ex)
{
bool rethrow = ExceptionPolicy.HandleException(ex, "Global Policy");
Response.Write(rethrow.ToString());

}

Output is "False".So I am strongly believe exceptions were caught by enterprise library : )-

Record retreiving C# using OracleProcedure

Oracle Proc:

create or replace procedure returnAllRecords(cur_allrec out t_cursor)
is
begin
open cur_allrec for SELECT * from Students;
end returnAllRecords


on Button click event write this below code:



OracleConnection Conn = new OracleConnection("Data Source=ORCL; User ID=scott; Password=tiger")
OracleCommand Cmd = new OracleCommand();
Cmd.Connection = Conn;
Cmd.CommandText = "returnAllRecords";
Cmd.CommandType = CommandType.StoredProcedure;
Cmd.Parameters.Add("cur_allrec", OracleType.Cursor).Direction = ParameterDirection.Output;
try

{

Conn.Open();

OracleDataReader Reader = Cmd.ExecuteReader();


}

catch (Exception ex)

{

Response.Write(ex.ToString();

}


Conn.Close();
