it encounters an error, then it returns 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 ora 12545 connect failed toad the host and port have been specified correctly. Check 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.

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

On Oracle DBA Forums, a user posts about having problems connecting on local workstation options to a new database. Below are the specifics of the question, as well as the original http://www.dba-oracle.com/t_ora_12454_connect_failed_because_target_host_or_object_does_not_exist.htm conflicts with ORA-12545: Question I have Oracle 9i 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 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 Sys or System and the password I created right after creating the database.Please advise on how I can get this to work? Answer: The replier advised two actions to begin resolving ORA-12545, starting by: making sure that your listener is running (lsnrcrl 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. Also important in resolving ORA-12545 if using VIP's is to "start by verifying connectivity via the DNS (e.g. /etc/hosts), and make sure to check your tnsnames.ora parms." Here is a helpful link to offer more information on troubleshooting connectivity errors. &#
