Oracle如何导出sys用户下的系统表

环境:Solaris 10 + Oracle 10.2.0.4

1.导出实例

导出sys用户下的 HIST_HEAD$WRI$_OPTSTAT_HISTHEAD_HISTORY 两张表:
由于expdp尝试导出失败,改用传统exp导出,导出命令如下:

% 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 &

传统exp可以正常导出,导出过程显示如下:

Export: Release 10.2.0.4.0 - Production on 星期五 1030 13:49:51 2015

With the Partitioning, OLAP, Data Mining and Real Application Testing options
已导出 ZHS16GBK 字符集和 AL16UTF16 NCHAR 字符集

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