linux下进行oracle的逻辑备份shell脚本

1.创建一个脚本schema_exp.sh

[oracle@localhost ~]$ ls
afiedt.buf      hot_backup.sh        rman_backup.sh  sqlnet.log
cold_backup.sh    schema_exp.sh

2.schema_exp.sh代码:

#!/bin/bash


 log_file=/oracle/admin/$ORACLE_SID/full_exp_$ORACLE_SID.log


 exp_arguments="userid=system/oracle buffer=10485760 owner=$1"


 if [ $2 ]


 then


   exp_arguments="$exp_arguments file=$2"


 else


   exp_arguments="$exp_arguments file=/oracle/bakup/luoji/"$ORACLE_SID"_full_export.dmp"


 fi


 


 echo "Beginning full db export..." > $log_file


 echo "Exporting with following arguments: $exp_arguments">> $log_file


  exp $exp_arguments >> $log_file 2>&1


 echo "Export finished." >> $log_file


 date >> $log_file


 


 exp_result=$?


  if [ exp_result!=0 ]


 then


   mail -s "Errors in exporting $ORACLE_SID." zgk_baqi@126.com< $log_file


 fi

3.执行脚本

[oracle@localhost ~]$ chmod +x schema_exp.sh 

[oracle@localhost ~]$ ./schema_exp.sh zgk    导出zgk用户下的数据
