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：

1. 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.

2. 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.

Object is listed in ku_noexp_view.

This view is a union of ku_noexp_tab and noexp$ tables.

Objects that are listed in this view are not exported.

Object is ORACLE_MAINTAINED='Y' in ALL_OBJECTS (and DBA_OBJECTS).

在视图 sys.Ku_Noexp_View 中或 DBA_OBJECTS 的 ORACLE_MAINTAINED 列为 Y 的对象不能导出。

SELECT * FROM sys.Ku_Noexp_View d WHERE d.name LIKE '%WRH%' ;

SELECT * FROM DBA_OBJECTS d WHERE d.ORACLE_MAINTAINED = 'Y' AND D.object_name LIKE 'WR%' ;

解决该报错的方法是：

1. 使用 exp 导出

2.ctas 的方法在不受限制的 schema 下创建表，然后导出该新建的表

3. use the DBMS_AUDIT_MGMT package of Audit Vault to manage and purge audit data (see Note 731908.1). This allows for the facility to move the AUD$ table out of the SYSTEM tablespace, which can negate the need to export the table.

注意： This issue also applies to other SYS owned auditing tables such as FGA_LOG$

In this Document

APPLIES TO:

Information in this document applies to any platform.
ORA-39165: Schema SYS was not found.
ORA-39166: Object AUD$ was not found.
ORA-31655: no data or metadata objects selected for job
Job "SYS"."SYS_EXPORT_TABLE_01" completed with 3 error(s) at 13:49:47

CAUSE

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.

SOLUTION

Export the table SYS.AUD$ using the traditional export:

#> exp system/<password> file=dumpfile.dmp log=logfile.log tables=sys.aud$

Other options are:

Use CTAS (Create Table As Select) to copy the SYS.AUD$ data into a non-restricted schema.
Use the DBMS_AUDIT_MGMT package of Audit Vault to manage and purge audit data (see Note 731908.1 ).
This allows for the facility to move the AUD$ table out of the SYSTEM tablespace, which can negate the need to export the table.

NOTE:
This issue also applies to other SYS owned auditing tables such as FGA_LOG$
