Oracle冷备迁移脚本(文件系统)

两个脚本：

1. 配置文件生成脚本dbinfo.sh
2. 网络拷贝到目标服务器的脚本cpdb16.sh

1. 配置文件生成脚本

#!/bin/bash

#Usage: create db.config file which includes datafile,tempfile,controlfile and logfile.

#You need reset these environment variables: $ORACLE_SID $ORACLE_BASE $ORACLE_HOME $PATH

#ex: sh dbinfo.sh

#Author: Alfred Zhao

#Vertion: 1.0.0

#ENV

ORACLE_SID="jyzhao"

ORACLE_BASE="/u01/app/oracle"

ORACLE_HOME="/u01/app/oracle/product/11.2.0/db_1"

PATH="/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/oracle/bin:/u01/app/oracle/product/11.2.0/db_1/bin:."

#EXPORT

export ORACLE_SID=$ORACLE_SID

export ORACLE_BASE=$ORACLE_BASE

export ORACLE_HOME=$ORACLE_HOME

export PATH=$PATH

#CREATE db.config

sqlplus / as sysdba <<EOF > /tmp/dbtemp.config

set linesize 200 pagesize 8888

select name from v\$datafile union all

select name from v\$tempfile union all

select name from v\$controlfile union all

select member from v\$logfile;

EOF

cat /tmp/dbtemp.config | grep / > /tmp/db.config

rm -f /tmp/dbtemp.config

注：需要根据你实际环境配置对应的环境变量。

执行上述脚本生成配置文件/tmp/db.config

2. 网络拷贝到目标服务器的脚本

#!/bin/bash

#Usage: copy db files after DB shutdown immediate!! ssh login without password is needed.

#You need redefine these variables：$IP $Destination

#ex: nohup sh cpdb16.sh &

#Author: Alfred Zhao

#Version: 1.0.0

#Define Variables

IP="192.168.9.149"

Destination="/var/run/sr-mount/df66f479-3da0-05cc-210c-00bc9c5a65cc/db16/"

#SCP

while read line

do

	scp $line $IP:$Destination

done < /tmp/db.config

注：这里scp需要配置ssh无密码登录才可以后台运行。

ssh无密码登录配置可参考：http://www.cnblogs.com/jyzhao/p/3781072.html

关注进程信息掌控迁移进度

```
# ps -ef | grep cpdb | grep -v grep
root 31638 1 0 16:39 ? 00:00:00 sh cpdb16.sh
# ps -ef | grep scp | grep -v grep
