Do database links support TAF?

DB Links do not use the complete OCI8 code path–thus TAF will not work. If you have a DB Link activiated and pointing to a database that has failed, you will get an ORA-03113 EOF on comm. channel error (even if the database has been recovered). Once you get this error, the link will become invalid, and the next time you attempt to use the link it will be re-established using the connect string with which it was originally defined.
