    Volla!!

    Now you have two options... In your sqlnet.ora file, specify the domain name as it had been specified in the tnsnames and try.

    example say your tnsnames is to say

    orcl1.xyz.com= (....)


    in your sqlnet.ora file specify

    NAMES.DEFAULT_DOMAIN = xyz.com


    Second option is, just comment the NAMES.DEFAULT_DOMAIN

    and try....

    One of the above should work.

    Your port numbers have to be the same in both your TNSNAMES entries and your LISTENER.ORA.

    If your listener is listening on port 1521 and the tnsnames is trying to contact port 1526 or any other port number besides 1521 you will get a NO LISTENER error

    Try that.

    I believe that it could be just a minor mistake when configuring the Oracle .
    1. Have you startup Oracle Agent Service if you want to use
    OEM ?
    2. Can you use tnsping in your client machine to test the connection ?
