Ora-12545 Connect Failed ToadDon Burleson Blog ora-12545: connect failed because target host or object does not exist (dbd error: ociserverattach) ORA-12545: Connect failed because target host or object does not exist tips Oracle Error Tips by ora 12545 database link 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 to create a http://www.orafaq.com/wiki/ORA-12545 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 http://www.dba-oracle.com/t_ora_12545_connect_failed.htm 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.

target host or object does http://www.cryer.co.uk/brian/oracle/ORA12545.htm not exist Cause: Oracle suggest that this error indicates that the address specified (in the alias definition) is not valid. http://oracledba.bigresource.com/Instant-Client-ORA-12545-Connect-failed-because-target-host-or-object-does-not-exist-BRp06cOKX.html Possible Remedies: Oracle suggest ensuring that the ADDRESS parameters (in the TNSNAMES.ORA file) have been entered correctly; the most connect failed likely incorrect parameter is the node name.

If the protocol is TCP/IP, edit the TNSNAMES.ORA file to change the host name to a numeric IP address connect failed because and try again. It could be a network connectivity problem. Try pinging the host. This error has been observed on a laptop when the database was local, TCP/IP protocol used but the network card had been removed.
