Symptoms
ORA-600 [kzsviver:1] possibly followed by ORA-600 [kks-hash-collision] errors can occur when trying to set a users password via SQL or PL/SQL scripts using the “CREATE/ALTER USER … IDENTIFIED BY VALUES …” command syntax if a null password value, e.g. an empty string ”, is used.
Changes
The code is being executed in Oracle11g, and works successfully in previous releases.
Cause
This is due to unpublished bug:6755379 as identified in bug:6833049, and was deemed as expected behaviour by development due to the use of unsupported command syntax as the use of the ‘IDENTIFIED BY VALUES’ clause on a CREATE/ALTER USER statement is not officially documented, and is intended purely for internal use by the export/import utilities within the Oracle RDBMS.  Therefore it was deemed appropriate for this to raise an internal error as opposed to a user error as encountering a null password string would otherwise not be possible.

Additionally the use of export/import for general use is desupported in Oracle11g.
Solution
Ensure that users have none null passwords defined and don’t use the “ALTER USER … IDENTIFIED BY VALUES …” command syntax which is not officially documented and therefore not supported, and may cease to work in a future Oracle RDBMS version.

In 11g, the new hash value is stored in the USER$.SPARE4 column, see note 429465.1, if existing passwords must be migrated, make sure to make no errors in transferring this value to avoid this internal error.
