ORA-39213 Metadata processing not available

今天在执行EXPDP时遇到了这个错误：

Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.2.0 - Production
With the Partitioning, OLAP and Data Mining options
ORA-39006: internal error
ORA-39213: Metadata processing is not available

Metalink确认是一个又来已经的已知问题，可以尝试执行如下步骤解决：

connect / as sysdba
execute sys.dbms_metadata_util.load_stylesheets;

我的系统中，以上处理过程有效：

Oracle Database 10g Enterprise Edition Release 10.2.0.2.0 - Production
With the Partitioning, OLAP and Data Mining options

SQL> exec dbms_metadata_util.load_stylesheets

PL/SQL procedure successfully completed.

SQL> exit

此后导出可以顺利执行。
