rman备份与异机恢复

Posted 2020-09-14 Jt00

一.rman备份脚本并为定时任务

#!/bin/bash
source ~/.bash_profile
export LANG=en_US
BACKUP_DATE=`date +%d`
#RMAN_LOG_FILE=${0}.out
RMAN_LOG_FILE=backupinfo.out
TODAY=`date`
USER=`id|cut -d "(" -f2|cut -d")" -f1`
echo "---------------$TODAY--------------"
#export ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1
export RMAN=$ORACLE_HOME/bin/rman
export ORACLE_SID=DB11G
export ORACLE_USER=oracle

echo 1
echo "ORACLE_SID: $ORACLE_SID">>$RMAN_LOG_FILE
echo "ORACLE_HOME:$ORACLE_HOME">>$RMAN_LOG_FILE
echo "ORACLE_USER:$ORACLE_USER">>$RMAN_LOG_FILE
echo "==========================================">>$RMAN_LOG_FILE
echo "BACKUP DATABASE BEGIN......">>$RMAN_LOG_FILE
echo " ">>$RMAN_LOG_FILE
chmod 666 $RMAN_LOG_FILE
echo 2
WEEK_DAILY=`date +%a`
case "$WEEK_DAILY" in
"Mon")

BAK_LEVEL=error
esac
export BAK_LEVEL=$BAK_LEVEL
echo "Today is : $WEEK_DAILY incremental level= $BAK_LEVEL">>$RMAN_LOG_FILE
run1="
BAK_LEVEL=$BAK_LEVEL;
export BAK_LEVEL

#+--------------------------------------------------------------+

二.异机恢复

在备份机器上面安装数据库软件，新建相应的目录及配置权限。（尴尬）做的恢复笔记找不到了。

有时间再来一次。
