[tolkien@rivendell public_html]$ oerr ORA 12545

12545, 00000, "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.
