ORA-12502: TNS:listener received no CONNECT_DATA from client
 *Cause:  No CONNECT_DATA was passed to the listener.
 *Action: Check that the service name resolved from TNSNAMES.ORA has
 the CONNECT_DATA component of the connect descriptor.

Regards
Michel

I am surprised Michel did NOT ask for this.

I have checked that and its in place. I have seen this solution mention as the action but this is not the case, everything in tnsname is ok

The connections with sqlplus is hanging when you use @<tnsname> to connect.
