  昨天payment从测试库到另外一个测试库进行迁移，导出时，出现如下故障：

  [oracle@oracle02 ~]$ exp userid=test/test file=test.dmp buffer=1024 owner=test

  Export: Release 10.2.0.1.0 - Production on Tue Nov 28 15:09:42 2006

  Copyright (c) 1982, 2005, Oracle. All rights reserved.

  Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production

  With the Partitioning, Real Application Clusters, OLAP and Data Mining options

  Export done in ZHS16GBK character set and AL16UTF16 NCHAR character set

  About to export specified users ...

  .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.

  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;

  V V OWNER_NUM OWNER_NAME URL

  重新执行导出程序exp，一些正常。
