Oracle : Ошибка ORA-12651

"Encryption or data integrity algorithm unacceptable"
*Cause: The algorithm the server chose to use for encryption or
data integrity was not one of the choices acceptable to
the client. This is either the result of an internal
error, of a network data transmission error, or of
deliberate tampering with the transmitted data.
*Action: For further details, turn on tracing, re-execute the
operation, and contact Oracle Customer Support.
