Dear All,
I have created database(11gR2 11.2.0.4.0) in Linux Redhat Linux on VM.
Database is properly functioning on the server(i.e tns is working and listener is functioning properly).
From remote PC ping command successful to server.
In remote PC the tns file is coppied from Server.
But when I ping tns it return following error:

TNS-12535: TNS:operation timed out

How to solve this or which part I check to identify the actual problem.

Your advice will be appreciated.

Regards

Mahmud

TNS-12535: TNS:operation timed out
 *Cause: The requested operation could not be completed within the time out
 period.
 *Action: Look at the documentation on the secondary errors for possible
 remedy. See SQLNET.LOG to find secondary error if not provided explicitly.
 Turn on tracing to gather more information.


Set your firewall to let Oracle pass through.

Make sure that you

and post (formatted) your connection string and sqlnet.ora and tnsnames.ora.

What does the following show?
$ telnet <database_server> 1521
As Michel says, firewall is the most likely culprit.
