错误原因
dbms_metadata.get_ddl需要调用Oracle dictionary table “sys.metastylesheet.”中的XSL stylesheets,但是由于某种原因,使得调用失败,出现上述错误.因为该错误可能有:
1.XSL stylesheets没有安装
2.使用alter database 修改数据库字符集(本库是因为昨天修改字符集导致)

解决办法(sys用户执行)
1.在10g及其以上版本中(不带参数)

SQL> exec dbms_metadata_util.load_stylesheets;

PL/SQL procedure successfully completed.

2.在9i版本中(带dir参数)

SQL> exec dbms_metadata_util.load_stylesheets('/u01/oracle/9.2.0/db_1/rdbms/xml/xsl');

PL/SQL procedure successfully completed.

SQL> select dbms_metadata.get_ddl('TABLE','XFF_IOT','CHF1') from dual;
