expdp导出时有如下报错：
Export: Release 11.2.0.1.0 - Production on Wed Feb 5 09:55:13 2020 Copyright (c) 1982, 2009, Oracle and/or its affiliates. All rights reserved.

按照提示进行操作，解决问题：
根据oerr ora 39213提示，执行exec dbms_metadata_util.load_stylesheets;
[oracle@data ~]$ sqlplus / as sysdba SQL*Plus: Release 11.2.0.1.0 Production on Wed Feb 5 09:59:26 2020 Copyright (c) 1982, 2009, Oracle. All rights reserved.

SQL> exit Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production With the Partitioning, OLAP, Data Mining and Real Application Testing options
再进行导出正常，问题解决。
