Enterprise Library 2006 -- Calling Oracle Procedure with Parameters

[TattedProgrammer]

Hello All,

I am completely stuck, I have tried for an entire day to get a simple
procedure call to my Oracle Db via the enterprise Library 06. I am not
an oracle fan to start, but have to deal with it for now. I am only
trying to retrieve data into a dataset from the oracle procedure,
nothing fancy! Here is my 100th version of code I have.
[ORACLE PROCEDURE I AM CALLING]

PROCEDURE "METLAB"."GET_L OOKUPS_PRC" (
"P_LOOKUP_T YPE" IN VARCHAR2, P_RETURNSET OUT SYS_REFCURSOR) IS

BEGIN

OPEN P_RETURNSET FOR

SELECT LOOKUP_ID,
LOOKUP_VALUE,
LOOKUP_TYPE
FROM MRLOOKUPS
WHERE LOOKUP_TYPE = P_LOOKUP_TYPE
ORDER BY LOOKUP_VALUE ASC;

NULL;

END "GET_LOOKUPS_PR C";
[code] [#01]
OracleDatabase db = new OracleDatabase( dbConn);
DbCommand objComm = db.GetStoredPro cCommand("GET_L OOKUPS_PRC");

db.AddInParamet er(objComm, "P_LOOKUP_TYPE" ,DbType.String, "NACE");
db.AddOutParame ter(objComm, "P_RETURNSET",D bType.Object,80 00);

objDS = db.ExecuteDataS et(objComm);
I would really like to continue writing the code similar to what I have
been doing with the Application Block previous. [HERE IS WHAT I AM USE
TO]
//Create Sql Parameters for SP
SqlParameter[] arrParms = new SqlParameter[3];
arrParms[0] = new SqlParameter("@ p_UserName", arr[0]);
arrParms[1] = new SqlParameter("@ p_DbId", arr[1]);
arrParms[2] = new SqlParameter("@ p_AddRemove",
GetAddRemove((( CheckBox)sender ).Checked));

//Update the records//
SqlHelper.Execu teNonQuery(strC onnection,
CommandType.Sto redProcedure, "up_AddOrRemove Perms", arrParms);

[MY CLOSEST ATTEMPT FOR THE ORACLE SIDE OF IT .. STILL DOESN'T WORK]
[#02]
Dataset objDS = new Dataset;
OracleParameter[] arrParams = new OracleParameter[2];

arrParams[0] = new
OracleParameter ("P_LOOKUP_TYPE ",OracleType.Va rChar,50);
arrParams[1] = new OracleParameter ("P_RETURNSE T", OracleType.Curs or);
objDS = db.ExecuteDataS et("GET_LOOKUPS _PRC", arrParams);

THE ERROR FOR [#02]
"Object must implement IConvertible"

ANY DOCUMENTATION LINKS OR HELPFUL SOURCE CODE FOR ORACLE USING THE
ENTERPRISE LIBRARY WOULD BE MUCH APPRECIATED.

Thank in advanced!!
