Connection via Native Network Encryption (NNE) fails

Make sure that you have the required permissions.

  1. Grant permission on tables v_$session_connect_info and v_$mystat to the user as these are the corresponding synonyms too.

    If you can’t grant permissions directly, run the following commands:

    GRANT SELECT ON v_$mystat TO <user>
GRANT SELECT ON v_$session_connect_info TO <user>

  2. Run the following commands:

    select network_service_banner from v$session_connect_info where sid in (select distinct sid from v$mystat);

  3. Verify the output for the queries mentioned above.
