oracle自动备份脚本

自己写得oracle备份脚本，可在oracle用户下，用crontab命令添加自动任务。

#!/bin/bash

# This shell is used to backup oracle database
# Backup occurs on erery Wed and Sun
# Create by menchao on 20110930
home=/u01/app/oracle/
sh $home/.bash_profile
day=`date +%Y%m%d`
echo "$weekday" > a.txt
mkdir -p /u01/backup/$day
bakdir=$home/backup
 cat >>$bakdir/rman.cmd   <<EOF
        run{
        allocate channel ch1 type disk;
        allocate channel ch2 type disk;
        backup as compressed backupset
        format='${bakdir}/fullbak_%d_%U'
        tag='${day}_fullbak'
        channel=ch1
        database;
        sql "alter system switch all logfile";
        backup as compressed backupset
        format='${bakdir}/arc_%d_%U'
        tag='${day}_arc'
        channel=ch2
        archivelog all  delete input;
        backup as compressed backupset
        format='${bakdir}/control.ctl'
        tag='${day}_control'
        channel=ch2
        current controlfile;
           }
        exit;
EOF
rman target / msglog=${bakdir}/bak_${day}.log cmdfile=${bakdir}/rman.cmd

此处是没有搭建catalog环境的，即采用controlfile备份。如果有catalog的，只需在rman命令一行，稍作修改，比ing在cat命令exit之前，加上一句"resync catalog;"。假设catalog的链接字串为：rman/rman@dbcat，

 

rman target / catalog rman/rman@dbcat msglog=${bakdir}/bak_${day}.log cmdfile=${bakdir}/rman.cmd
