12203, 00000, "TNS:unable to connect to destination"

// *Cause: Invalid TNS address supplied or destination is not listening.
// This error can also occur because of underlying network transport
// problems.
// *Action: Verify that the service name you entered on the command line
// was correct. Ensure that the listener is running at the remote node and
// that the ADDRESS parameters specified in TNSNAMES.ORA are correct.
// Finally, check that all Interchanges needed to make the connection are
// up and running.

Pretty self explanatory I think. Some RTFM'ing helps. :-)

You can also use TNSPING to test the TNS alias. I'm sure there's something wrong with your TNSNAMES.ORA file.
