Issue using Oracle ODBC driver in Script Task in SSIS 2008

Question

The issue I'm having may not have anything to do with SSIS but I wanted to be thorough. I am attempting to have essentially the same code (using ODBC) accessing SQL Server, Sybase, and Oracle. Everything except Oracle is working (not surprising) but I'm at a loss as to how to resolve this issue.

The Oracle driver is the 11.01.00.06 version. I am able to connect successfully to the instance but the call (to the function) fails. I'm guessing the error has to do with the fact that the cursor is a parameter in this case (not true for SQL Server and Sybase) and I am not accounting for it. There is no OdbcType for cursor though.

Any help or suggestions would be appreciated.

The error I am getting is - ERROR [07001] [Oracle][ODBC][Ora]ORA-01008: not all variables bound

Calling code (C#)

    NetworkProviderCon = new OdbcConnection(strCon);
    NetworkProviderCon.Open();
    NetworkProviderCmd.Connection = NetworkProviderCon;

    NetworkProviderCmd.CommandType = CommandType.StoredProcedure;

    NetworkProviderCmd.CommandText = "{CALL SP_NETWORK_IDL(?,?)}";

    NetworkProviderCmd.CommandTimeout = this.Variables.CADATABASECORETIMEOUT;

    //parameters to call SP   
    NetworkProviderParam1 = NetworkProviderCmd.Parameters.Add("@pdtStartTime", OdbcType.DateTime);
    NetworkProviderParam1.Value = strStartDate;
    NetworkProviderParam2 = NetworkProviderCmd.Parameters.Add("@pdtEndTime", OdbcType.DateTime);
    NetworkProviderParam2.Value = strEndDate;
    sqlDr = NetworkProviderCmd.ExecuteReader();

Procedure Parameters

CREATE OR REPLACE function XXXX.SP_NETWORK_IDL

Your function requests 3 parameters, but you are passing only 2.

NetworkProviderCmd.Parameters.Add
  ("@pRESULT_CURSOR", OracleType.Cursor).Direction = ParameterDirection.InputOutput;
//NetworkProviderCmd.Parameters["pRESULT_CURSOR"].Value will store your output

UPD :

MSDN: Using Parameters with an OleDbCommand or OdbcCommand

NetworkProviderParam0 = NetworkProviderCmd.Parameters.Add("@pRESULT_CURSOR", OracleType.Cursor);
NetworkProviderParam0.Direction = ParameterDirection.InputOutput;

PS: I can not find OdbcType for cursor

UPD2 :

NetworkProviderCon = new OdbcConnection(strCon);
NetworkProviderCon.Open();

OdbcCommand NetworkProviderCmd = new OdbcCommand();
NetworkProviderCmd.CommandText = "{? = SP_NETWORK_IDL(?,?,?)}";
NetworkProviderCmd.Connection = NetworkProviderCon;
NetworkProviderCmd.CommandTimeout = this.Variables.CADATABASECORETIMEOUT;
NetworkProviderCmd.CommandType = CommandType.StoredProcedure;

//parameters to call SP 
NetworkProviderCmd.Parameters.Add("pRESULT_CURSOR", OracleType.Cursor).Direction = ParameterDirection.InputOutput; //NetworkProviderParam1
NetworkProviderCmd.Parameters.Add("pdtStartTime", OdbcType.DateTime).Value = strStartDate; //NetworkProviderParam2
NetworkProviderCmd.Parameters.Add("pdtEndTime", OdbcType.DateTime).Value = strEndDate; //NetworkProviderParam3
NetworkProviderCmd.Parameters.Add("RETURN_VALUE", OdbcType.Int).Direction = ParameterDirection.ReturnValue; //NetworkProviderParam4
