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.

Only had this error when the database had gone down while having an open SQL*Plus session, so can't help you much

Hi gurus,

     Anyone of u have come across the ora-12545 error?
     I am getting this error when i am trying to connect from sqlplus
     8.1.6 to 8.1.5 database. The error message is

     ORA-12545 Connect failed because target host or object does not

     This happens from one m/c alone. Even from this machine tnsping
     is ok to this database.

     It connects from sqlplus 8.1.5 to the same db from another m/c.

     The compatible parameter for the database is 8.1.0.

     I am not able to find the error message help for this particular
     error from the manuals also.

     Waiting for ur replies. Any help will be of great use.
