How To Resolve Ora-12545 Error
installed on my local Windows XP workstation that will be used for local development only. Now I am trying to create a database and using OEM Database Configuration Assistant. I put in FirstDB for https://community.oracle.com/thread/2482773 the Global Database Name and put in FirstDB for the SID. I completed the wizard and set up my tnsnames.ora file with the SID and hostname. Then I tried to connect using OEM with the Sys login and it says: ORA-12545:Connect failed because target host or object does not exist. Should I put in localhost or 127.0.0.1 for my Global Database Name? I assume I connect as http://www.dba-oracle.com/t_ora_12545_connect_failed.htm Sys or System and the password I created right after creating the database. Please advise on how I can get this to work? Answer: Use oerr to look up the ORA-12545 error: ORA-12545: Connect failed because target host or object does not exist Cause: The address specified is not valid, or the program being connected to does not exist. Action: Ensure the ADDRESS parameters have been entered correctly; the most likely incorrect parameter is the node name. Ensure that the executable for the server exists (perhaps "oracle" is missing.) If the protocol is TCP/IP, edit the TNSNAMES.ORA file to change the host name to a numeric IP address and try again.
I would start to debug a ORA-12545 error with these steps: making sure that your listener is running (lsnrctl stat) testing connectivity with ping, and then tnsping. verifying connectivity via the DNS (e.g. /etc/hosts) make sure to check your tnsnames.ora parms.

The following works while using System.Data.OracleClient - but 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? I had to change the program to be 32 bit for the Oracle.DataAccess.dll to load. Is this even the correct library to be using??? Thanks EDIT tnsnames.ora file as follows: # tnsnames.ora Network Configuration File: C:\app\UserName\product\11.2.0\dbhome_3\network\admin\tnsnames.ora # Generated by Oracle configuration tools. ORAC = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1522)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orac.example.com) ) ) LISTENER_ORAC = (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1522)) UPDA
