使用DBLINK查询时报ORA-00600: internal error code, arguments: [kzdlk

当尝试使用DBLINK查询时遇到ORA-00600错误，此问题可能由于在Oracle 10g中数据库链接密码的加密方式改变导致。'IDENTIFIED BY VALUES'子句仅用于内部Oracle工具，错误使用可能导致该内部错误。解决方案并不涉及修复，而是提高错误信息的用户友好性。

create public database link dblink_ogg1
connect to lhr identified by lhr
using '(DESCRIPTION =
　　 (ADDRESS_LIST =
　　 (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.59.129)(PORT = 1521))
　　 )
　　 (CONNECT_DATA =
　　 (SERVICE_NAME = ogg1)

create public database link DBLINK_OGG1
connect to LHR identified by lhr
using 'OGG1';
SELECT NB.PASSWORD FROM sys.USER$ NB WHERE NB.NAME = 'SYS';
--ORA-00600: internal error code, arguments: [kzdlk_zt2 err],
create public database link DBLINK_OGG1
connect to LHR identified by values '72979A94BAD2AF80'
using 'OGG1';
CREATE DATABASE LINK DBLINK_OGG1
CONNECT TO CURRENT_USER
USING 'remote';
CREATE DATABASE LINK DBLINK_OGG1
USING 'remote'

在测试重建DBLINK，因为不知道帐号的密码，所以使用了IDENTIFIED BY VALUES进行创建：
SQL> CREATE PUBLIC DATABASE LINK WEBDB CONNECT TO WEBAPP identified by values '3960A527B983671C' using 'CSS';

Database link created.
创建过程一切OK，但是在使用时问题就来了：

SQL> select sysdate from dual@WEBDB;
select sysdate from dual@WEBDB
