ORA-39006: internal error
ORA-39213: Metadata processing is not available
网上查了下，解决方法如下描述：
Cause: The Data Pump could not use the Metadata API. Typically, this is caused by the XSL stylesheets not being set up properly.
Action: Connect AS SYSDBA and execute dbms_metadata_util.load_stylesheets to reload the stylesheets.
执行如下：
