ORA-12454: connect failed because target host or object does not exist tips Oracle Error Tips by Stephanie F ora-12545 sqlplus The Oracle docs note this on the ora-12454 error: ORA-12545: Connect failed because target host or object does not exist Cause: The address specified is not valid, or the program being ora-12545 connect failed because target host or object does not exist (dbd error ociserverattach) connected to does not exist.

The following works while using System.Data.OracleClient - but http://stackoverflow.com/questions/18252635/ora-12545-connect-failed-because-target-host-or-object-does-not-exist-no-erro obviously this is depreciated. When using the exact same code but using Oracle.DataAccess.OracleClient I get the following error {"ORA-12545: Connect failed because target host or object does not exist"} Here is my code using (OracleConnection con = new OracleConnection("Data Source=orac;User Id=SYSTEM; Password=Pass;")) { con.Open(); Console.WriteLine("Connection opened"); OracleCommand cmd2 = new OracleCommand("SELECT * FROM SYSTEM.TABLE", con); OracleDataReader oracleDataReader = cmd2.ExecuteReader(); while (oracleDataReader.Read()) { Console.WriteLine(oracleDataReader[0]); } } Could anyone help me out with what I am doing wrong?
