ORA-00600 [kzdlk_zt2 err]
今天在查询一个视图的时候一直报ora-600错误
ORA-00600: internal error code, arguments: [kzdlk_zt2 err], [18446744073709551603], [], [], [], [], [], []
这个视图是通过一个私有同义词创建的，然后授权给其他用户访问。
道理这样是没有问题的。可以正常访问。

那这是什么原因呢？突然想起这个问题是下午才出现的，这个db_link是上午才创建的。问题应该是创建的问题。但是创建的时候又没有问题啊！！显示是创建成功了的。
但是找不到其他的原因。把db_link重新创建了一次就可以了。实在是太奇怪了。
在metlink上搜索了一下。

Changes
The database has been recently updated to Oracle 10g and the database link used to work in previous versions.
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The exception is caused by the unpublished below :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 database link security. The "IDENTIFIED BY VALUES" clause is only intended 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.
Solution
The only possible fix for this bug is to raise a user error rather than an internal error in this case. This won't make the error go away but it might be more informative to the user, however, seeing as this functionality is only intended to be used by internal Oracle utilities it seems that an internal error may be more appropriate.
Therefore this exception is not a bug.
这个上面说的是不能用密文创建db_link,但是上面的测试很清楚。可以创建而且还可以正常使用。难道是密码的问题？
做了个测试，确实是密码有问题，会报这个错误。但是oracle写的是这个意思么？哎英文水平太差了。。

还请英文好的兄弟指点一二。。
谢谢
