BUG TYPE CHOSEN
===============
Code

SubComponent: Dictionary
========================
DETAILED PROBLEM DESCRIPTION
============================
Impdp fails with ORA-600: internal error code, arguments:
[kqlInvObj:user], [94]

Failing statement is CREATE TABLE "SYSTEM"."SYS_IMPORT_FULL_01

DIAGNOSTIC ANALYSIS
===================
We tried to patch data dictionary using this procedure:

1. SHUTDOWN IMMEDIATE or NORMAL
2. STARTUP RESTRICT
3. Create a new user called PATCH_USER:

create user PATCH_USER identified by p;

4. Update obj$

update sys.obj$
set owner# = (select user#
               from sys.user$
               where name = 'PATCH_USER')
where owner# in (88,94);

5. COMMIT;
6. Shutdown abort;
7. STARTUP
8. Drop user created in step 3:

drop user PATCH_USER cascade;

After this is completed impdp works no errors, however hcheck.full shows a
new inexistant user with objects in OBJ$.

We repeated the procedure again and same results, please see output3.txt.

Looks like drop PATCH_USER cascade, drops the user but doesn't remove the
objects from OBJ$.

WORKAROUND?
===========
No

TECHNICAL IMPACT
================
Now no errors anymore, but customer is afarid of future issues because of
this data dictionary inconsistency.

但没有相关的补丁，于是按照文档说明，自己修改sys.obj$信息的方式处理，步骤如下：

SQL> select * from sys.obj$

2 where owner# in (42);
