ORA-39006: internal error
ORA-39213: Metadata processing is not available[/code]
根据MOS文档（ID 801337.1)，首先执行如下
exec sys.dbms_metadata_util.load_stylesheets;
发现执行成功，且impdp正常没报错。
另外，文档中提到如果执行过程中报错：
[code]SQL> exec dbms_metadata_util.load_stylesheets;

BEGIN dbms_metadata_util.load_stylesheets; END;

ERROR at line 1:
ORA-22288: file or LOB operation FILEEXISTs failed
Permission denied
ORA-06512: at "SYS.DBMS_METADATA_UTIL", line 1807
ORA-06512: at line 1[/code]
这是由于执行过程中需要读$ORACLE_HOME/rdbms/xml/xsl文件，调整文件权限重新执行即可。
