1.導出實例
導出sys用戶下的`HIST_HEAD$`和`WRI$_OPTSTAT_HISTHEAD_HISTORY`兩張表： 由於expdp嘗試導出失敗，改用傳統exp導出,導出命令如下： ``` % nohup exp system/****** file=/tmp/jy/system_exp_2tables.dmp log=/tmp/jy/exp_system_exp_2tables.log tables=sys.HIST_HEAD\$, sys.WRI\$_OPTSTAT_HISTHEAD_HISTORY & ``` 傳統exp可以正常導出，導出過程顯示如下： ``` Export: Release 10.2.0.4.0 - Production on 星期五 10月 30 13:49:51 2015Copyright (c) 1982, 2007, Oracle.

SYMPTOMS
DataPump export of table SYS.AUD$ fails with errors:
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/
file=dumpfile.dmp log=logfile.log tables=sys.aud$
