your DNS server? You can try tracing the path or the route a connection is taking from the client to the server. If it encounters an error, then it returns ora-12545 network transport the error stack which gives us more information when compared to an cryptic one line error. Execute the following: trcroute host_name This will help you find the problem and fix it. The problem may fall into one of the following areas: Check TNSNAMES.ORA: The TNSNAMES.ORA may contain a wrong address. Check the host and port have been specified correctly. Check ora 12545 connect failed toad the details against the LISTENER.ORA file. Check the remote node: Check if the listener has been started on the remote node. Check the status with the STATUS command of the listener control utility (lsnrctl): lsnrctl lsnrctl> status listener_name listener_name is the name of the listener defined in the listener.ora file. If you have not changed the listener name, then it would be called LISTENER. If the listener has not been started, start it with the command: lsnrctl> start listener_name You can check if the fix worked by executing tnsping. It should return an "OK" message if the TNSPING has been successful.

ora-12545 toad ORA-12545: Connect failed because target host or object does not exist tips Oracle ErrorOra-12545 Utl_http
Tips by Burleson Consulting Question: I have Oracle 9i installed on my local Windows XP workstation that will be used for local development only. Now I am trying http://www.orafaq.com/wiki/ORA-12545 to create a database and using OEM Database Configuration Assistant. I put in FirstDB for 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 http://www.dba-oracle.com/t_ora_12545_connect_failed.htm 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 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.
