于是就搜到了如下文章：
ataPump Export (EXPDP) Fails With Error ORA-39165 Schema SYS Was Not Found (Doc ID 553402.1)
该文章给出了如下答案：
There is a restriction on dataPump export. It cannot export schemas like SYS, ORDSYS, EXFSYS, MDSYS, DMSYS, CTXSYS, ORDPLUGINS, LBACSYS, XDB, SI_INFORMTN_SCHEMA, DIP, DBSNMP and WMSYS in any mode.
The Utilities Guide indicates the restriction only on full export mode, but the restriction actually applies to all modes.
MOS ： Why Can an Object Not Be Exported? Expdp of SYSTEM User's Table Returns ORA-39166 or ORA-31655 (文档 ID 2114233.1) 列出来了哪些对象不能导出：
Objects (tables, views, schemas, etc) which fall under either of below conditions are not exported with expdp because they are regarded as system maintained objects.
