odd remote connection problem - ORA-12514

edited Oct 17, 2014 8:21AM in Database Networking (MOSC) 3 commentsAnswered ✓

I have a 11.2.0.3 server running with different instances. One is named ORCL, the other SEIMANS (name changed

On the server in a DOS box I can type

SQLPLus user/password@orcl as well as SQLPLus user/password@seimans

and get logged in fine.

On the remote client I can connect

SQLPLus user/password@seimans  fine.

When I type

SQLPlus user/password@orcl I'm getting an ORA-12514

There is no environmentvariable ORACLE_HOME set. TNS_ADMIN is set to

TNS_ADMIN=c:\app\kuku\product\11.2.0\client_5\Network\Admin

and the tnsnames.ora there contains:

LISTENER_ORCL =

  (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))

Howdy, Stranger!
