Error Ora-604 on connect from Visual Studio 2008 to Oracle database

Question

Hello!
I have installed Oracle 9.2.0.6 Database, Microsoft Visual Studio 2008 and today I succesfully installed ODP.NET 1110621.
I wrote a simple console application like this:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Oracle.DataAccess.Client;
using Oracle.DataAccess.Types;
using System.Data;
namespace ConsoleApplication1
class Program
static void Main(string[] args)
OracleConnection c = new OracleConnection();
c.ConnectionString = "Data Source=(DESCRIPTION="
+ "(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.1.1)(PORT=1521)))"
+ "(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=ssss)));"
+ "User Id=user;Password=pwd;";
c.Open();
OracleCommand cmd = new OracleCommand();
cmd.CommandText = "Select * from CATEGORY_TABLE";
cmd.CommandType = CommandType.Text;
cmd.Connection = c;
OracleDataReader dr = cmd.ExecuteReader();
while (dr.Read())
Console.WriteLine(dr[0].ToString() + " " + dr[1].ToString());
dr.Dispose();
cmd.Dispose();
c.Dispose();
Console.ReadLine();
at line c.Open(); appear runtime error : ORA-604 Error occurred at recursive SQL level 1
How to solve it?

Answer 1

Your issue is not SQL and PL/SQL so much as .NET so I would suggest you ask the question in the "Windows and .NET" forum.
But a couple of thoughts:
1. Your database is undoubtedly not at "HOST=192.168.1.1"
This IP address is generally the address of the router not the server.
2. Why would you install an unpatched version of software so old it is in desupport mode and then try to work with it using a current
version of a Microsoft product? Would you be comfortable installing a 10 year old version of a Microsoft product and expect it to
work well with Oracle 11gR1?
