There's a program called "oerr"
so when you type:

 oerr ora 12154

You get:
12154, 00000, "TNS:could not resolve service name"

// *Cause:  The service name specified is not defined correctly in the
// TNSNAMES.ORA file.
// *Action:  Make the following checks and correct the error:
//           - Verify that a TNSNAMES.ORA file exists and is in the
proper
//             place and accessible. See the operating system specific
manual
//             for details on the required name and location.
//           - Check to see that the service name exists in one of the
//             TNSNAMES.ORA files and add it if necessary.
//           - Make sure there are no syntax errors anywhere in the
file.
//             Particularly look for unmatched parentheses or stray
characters.
//             Any error in a TNSNAMES.ORA file makes it unusable. See
//             Chapter 4 in the SQL*Net V2 Administrator's Guide. If
//             possible, regenerate the configuration files using the
Oracle
//             Network Manager.

Regarding your TNS aside. I don't know.
