Hi,
I can't connect to Oracle Database using tnsnames, that is what appears to be.
Scenario: In the database server, using sqlplus I can log in if I type sqlplus sys as sysdba. BUT in the same server I can not log in if I type sqlplus@<service> as sysdba.
So you can imagine I can not logging from a client computer with sqlplus or running SQL Developer for example.
I have checked listener.ora, tnsnames.ora and all seem right, also the status of the listener show up and shows the handler for the service.
Firewall down and still same issue.
What info should I share to get some help?
Thanks in advance.
