Oracle使用数据泵定时备份

1）创建导出目录
> sqlplus system/oracle
SQL> create directory dump_dir as '/home/oracle/dump';
Directory created.

（2）编写脚本

脚本存放位置：/home/oracle/

脚本名称：backup_logic.sh

脚本内容：

#!/bin/bash

 

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1

export ORACLE_SID=zxin

export PATH=$PATH:$ORACLE_HOME/bin

 

EXPFILE=`date '+exp%Y%m%d.dmp'`

LOGFILE=`date '+exp%Y%m%d.log'`

 

expdp system/oracle directory=dump_dir dumpfile=$EXPFILE logfile=$LOGFILE schemas=pingchuan,zte;

 

（3）执行脚本

> cd /home/oracle/

> ./backup_logic.sh
