According to doc 456320.1
Cause
The exception is caused by the unpublished below :Bug:5576894 - Abstract: GET ORA-600 [KZDLK_ZT2_ERR] WHEN LINK CREATED WITH 'IDENTIFIED BY VALUES'
In Oracle 10.2, dblink passwords are now stored in a special encrypted form to improve databse link security. Tthe "IDENTIFIED BY VALUES" clause is only intened for use by Oracle internal utilities (EXPORT/IMPORT), and it's not documented in the Oracle user documentation.
The only valid value to be passed in the "IDENTIFIED BY VALUES" clause is an encrypted dblink password identifier (note - this is different from the user password identifier stored in the PASSWORD column of USER$). The internal error in this bug is raised when we attempt to access the db link and materialize the plain text password from the encrypted dblink password identifier - because the value passed to the "IDENTIFIED BY VALUES" clause was not a valid encrypted dblink password identifier we raise an internal error. This is expected behavoiur in this case.
