ORA-12502: TNS:listener received no CONNECT_DATA from client, if laptop uses direct access via publi

edited Jul 17, 2018 5:11AM in Database Networking (MOSC) 3 commentsAnswered

The laptop is company owned and most of time it works on office via intranet connection.

While employee takes it home and use wifi (or any public wifi), the application cannot connect to database.

The laptop has installed Direct Access.

If ping <server> and tnsping <connection_string>, it shows correct information.

But SQL*Plus and application are not able to connect to database.

The error is "ORA-12502: TNS:listener received no CONNECT_DATA from client"

Is the Direct Access problem or Oracle client does not support Direct Access?

Thanks
