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 oracle ora 12545 IP address and try again. 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 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?

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. Also see MOSC notes (http://support.oracle.com) on the ORA-12545 error: Note 284909.1 - Intermittent ORA-12545 When Trying To Connect To RAC Database Note 364855.1 - RAC Connection Redirected To Wrong Host/IP ORA-12545 Note 291175.1 - Clients Failing to Connect Due to Intermittent ORA-12545 in RAC Environment Note 333159.1 - ORA-12545 Frequent Client Connection Failure - 10g Standard RAC Here is a helpful link to offer more information on troubleshooting connectivity errors. �� Burleson is the American Team Noit is shared".
