Oracle 数据库数据导出dump方式

linux下

[root@infodb111 ~]# su - oracle
[oracle@infodb111 /]$ mkdir /oracle/dump_dir
[oracle@infodb111 /]$ sqlplus / as sysdba
SQL> create directory dump_dir as '/oracle/dump_dir';
SQL> grant read,write on directory dump_dir to scott;
Grant succeeded
SQL> grant read,write on directory biappdump to maxthonbi;

创建脚本文件

 
[root@infodb111 ~]# vim biappdbback.sh 

#!/bin/sh
D=maxthon_$(date +%Y%m%d);
export D;
expdp 'maxthon/maxthon@orcl' directory=biappdump dumpfile=${D}.dmp

//保存退出

授权：

[root@infodb111 ~]# chown oracle:dba biappdbback.sh 
[root@infodb111 ~]# chmod 775 biappdbback.sh 

运行

[root@infodb111 ~]$ ./biappdbback.sh

发现有错误，查找错误原因

[oracle@infodb111 /]$ oerr ora 39006
39006, 00000, "internal error"
// *Cause: An unexpected error occurred while processing a Data Pump job.
//          Subsequent messages supplied by DBMS_DATAPUMP.GET_STATUS
//          will further describe the error.
// *Action: Contact Oracle Customer Support.
[oracle@infodb111 /]$ oerr ora 39213
39213, 00000, "Metadata processing is not available"
// *Cause: The Data Pump could not use the Metadata API. Typically,
//          this is caused by the XSL stylesheets not being set up properly.
// *Action: Connect AS SYSDBA and execute dbms_metadata_util.load_stylesheets
//          to reload the stylesheets.

根据oerr ora 39213提示，执行exec dbms_metadata_util.load_stylesheets;

再进行导出正常，问题解决。
