Home -> Community -> Usenet -> c.d.o.server -> Re: ORA-12545 - listener and/or tnsnames problem?
hi, just begin to learn oracle.
i don'know if it can help you. good luck.
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.
