今天做了一个简单的用户模式的exp导出，结果出了exp-00056错误和ora-00932错误。第一次实验，查了一下，解决的办法很简单，我慢慢说下思路。
我是想导出一个用户模式的信息，样的话会陆续导出了表的一些同义词，这个用户的视图，生么触发器，过程等等等跟这个用户相关的信息。但是出现了这个错误：
[oracle@oracle02 ~]$ exp userid=test/test file=test.dmp
buffer=1024 owner=test

EXP-00056: ORACLE error 932 encountered
ORA-00932: inconsistent datatypes: expected BLOB, CLOB got CHAR
EXP-00000: Export terminated unsuccessfully
原因：数据字典中有存在一些无效KU$_视图；
SQL> select * from sys.ku$_xmlschema_view;
select * from sys.ku$_xmlschema_view
*
ERROR at line 1:
ORA-00932: inconsistent datatypes: expected BLOB, CLOB got CHAR
解决办法：
1.执行对象视图定义脚本 $ORACLE_HOME/rdbms/admin/catmetx.sql
SQL>
@?/rdbms/admin/catmetx.sql
Package altered.
Index altered.
View created.
Grant succeeded.
View created.
Grant succeeded.
Procedure created.
System altered.
System altered.
System altered.
PL/SQL procedure successfully completed.
Procedure dropped.
------开始我用一个普通用户执行的这个，出现了一些错误，报什么某个表不存在，之后换了sys用户执行的，执行完了就一切正常了。。
2.执行重新编译无效对象脚本 $ORACLE_HOME/rdbms/admin/utlrp.sql
SQL> @?/rdbms/admin/utlrp.sql
PL/SQL procedure successfully completed.
PL/SQL procedure successfully completed.
验证一下程序
SQL> select * from ku$_xmlschema_view;

重新执行导出程序exp，一些正常。
Applies
to:
Oracle Server - Enterprise Edition - Version: 10.1.0.2 to 10.2.0.1
Oracle Server - Personal Edition - Version: 10.1.0.2 to 10.2.0.1
Oracle Server - Standard Edition - Version: 10.1.0.2 to 10.2.0.1
This problem can occur on any platform.
Symptoms
A full database export from a Oracle10g database aborts with:
...
. exporting cluster definitions
EXP-00056: ORACLE error 932 encountered
ORA-00932: inconsistent datatypes: expected BLOB, CLOB got CHAR
EXP-00056: ORACLE error 932 encountered
ORA-00932: inconsistent datatypes: expected BLOB, CLOB got CHAR
EXP-00000: Export terminated unsuccessfully
EXP-00000: Export terminated unsuccessfully
If export was started with SYS schema, a table level export may also fail with:
...
Current user changed to TEST
. . exporting table DOC_ARCHIVE 16 rows exported
Current user changed to SYS
EXP-00011: SYS.; does not exist
Export terminated successfully with warnings.
Cause
One possible cause (note there might be others):
Script $ORACLE_HOME/rdbms/admin/catmeta.sql has been run recently.
There are several invalid SYS.KU$_% views in the dictionary:
-- invalid objects:
SET lines 120 pages 2000
COL status FOR a9
COL object_type FOR a20;
COL owner.object FOR a50
SELECT status, object_id, object_type, owner||'.'||object_name "OWNER.OBJECT"
FROM dba_objects
WHERE status != 'VALID' AND object_name NOT LIKE 'BIN$%'
ORDER BY 4,2;
STATUS OBJECT_ID OBJECT_TYPE OWNER.OBJECT
--------- ---------- --------------- --------------------------------
INVALID 7105 PACKAGE BODY SYS.DBMS_METADATA
INVALID 6683 VIEW SYS.KU$_10_1_COMMENT_VIEW
INVALID 6788 VIEW SYS.KU$_10_1_IND_STATS_VIEW
INVALID 6778 VIEW SYS.KU$_10_1_PIND_STATS_VIEW
INVALID 6752 VIEW SYS.KU$_10_1_PTAB_STATS_VIEW
INVALID 6770 VIEW SYS.KU$_10_1_SPIND_STATS_VIEW
INVALID 6748 VIEW SYS.KU$_10_1_TAB_ONLY_STATS_VIEW
... (etc)
A query in SQL*Plus on sys.ku$_xmlschema_view also fails with ORA-932:
SET lines 200 pages 2000
COL url FOR a60 WRA
SELECT url, local, stripped_val
FROM sys.ku$_xmlschema_view;
ORA-00932: inconsistent datatypes: expected BLOB, CLOB got CHAR
Solution
For reasons having to do with compatibility, the XDB objects cannot be created by the catproc.sql script. The script catproc.sql therefore calls the catmeta.sql script, which contains fake object views for XDB objects.
The real object views are defined in the catmetx.sql script (this script is invoked by catxdbv.sql which is invoked by catqm.sql).
Solution #1
Run following scripts while connected as SYS user:
> sqlplus /nolog
SQL> connect / as sysdba
SQL> @?/rdbms/admin/catmetx.sql
SQL> @?/rdbms/admin/utlrp.sql
SQL> exit
Afterwards, re-run the export.
or:
Solution #2
Run the export with the Export DataPump client. E.g.:
> expdp system/manager directory=my_dir \
dumpfile=expdp_full.dmp logfile=expdp_full.log full=y

下面是转自晶晶小妹的一篇文章。或许以后能用到：
一个简单的EXP-00056：
今天在测试机上作导出，发现了如下错误：
D:> exp scott/ifclwx
Export: Release 10.2.0.1.0 - Production on 星期三 4月 2 09:52:08 2008
Copyright (c) 1982, 2005, Oracle. All rights reserved.
EXP-00056: 遇到 ORACLE 错误 6550
ORA-06550: 第 1 行, 第 41 列:
PLS-00302: 必须说明 'SET_NO_OUTLINES' 组件
ORA-06550: 第 1 行, 第 15 列:
PL/SQL: Statement ignored
EXP-00000: 导出终止失败
EXP-00056吗，这是一个很普通的错误，通常是由于EXP程序在执行某条命令错误所造成的，可以通过自己手动执行如下脚本解决，
@?/rdbms/admin/catmeta.sql
——注意跟我遇到的错误不同，执行的脚本也不同。
@?/rdbms/admin/catexp.sql
这种问题一般在升级过数据库后有可能出现，我以前也遇到过一次。于是，按照惯性思维，先执行第一个脚本，再EXP，错误依旧，再执行第二个脚本，同样不行。这可怎么办，忽然注意到EXP第一行显示的信息：Export: Release 10.2.0.1.0 - Production 。
数据库的版本是9i，而EXP确是10G，测试机上装了两个数据库，先装9i，后装的10G，PATH环境参数被设置为相关10G的，执行EXP时，并没有将环境参数改为9i的，设置一下PATH参数，或者进入到9i的文件夹下：cd E
racleora92in
，然后在执行EXP：
Eracleora92in>exp scott/ifclwx
一切顺利了。
如果你的测试机中9i和10g并存，就要注意这个问题了。
