rman  生产全备脚本 expdp备份用户脚本

expdp逻辑备份脚本：

#!/bin/bash

ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1

export ORACLE_HOME

ORACLE_SID=DAAS2

export ORACLE_SID

PATH=$PATH:$HOME/bin:/usr/bin:/bin:/usr/sbin:/usr/local/bin:$ORACLE_HOME/bin

export PATH

schmasname=(gsinfo datamart)

name=$(date +%Y%m%d)

DATE=$(date +%Y%m%d --date '7 days ago')

for user in ${schmasname[*]}

do 

expdp \'/ as sysdba\' directory=dudir dumpfile=$user-$name.dmp logfile=$user-$name.log  schemas=$user

cd /backup/data

tar zcvf $user-$name.tar.gz $user-$name.dmp

rm -rf $user-$name.dmp

rm $user-$DATE.tar.gz

rm $user-$DATE.log

done

rman物理备份脚本：

source /home/oracle/.bash_profile

name=$(date +%Y%m%d)

DATE=$(date +%Y%m%d --date '3 days ago')

rman 备份可以排除备份某个表空间

配置如下：

rman target /

configure exclude for tablespace DATAMART; #排除备份DATAMART表空间

show exclude;  #查看排除的表空间

configure exclude for tablespace DATAMART clear;  #清除排除备份的表空间

在进行数据库进行备份

##注释：出来DATAMART 表空间备份外其他的全部备份

rman target /  <

run {

allocate channel c1 type disk;

allocate channel c2 type disk;

allocate channel c3 type disk;

allocate channel c4 type disk;

backup database format '/backup/full_%d_%t_%s_%p';

sql'alter system archive log current';

backup archivelog all format '/backup/arch_%d_%t_%s_%p';

backup current controlfile format '/backup/ctl_%d_%t_%s_%p';

crosscheck backup;

crosscheck archivelog all;

}

EOF

恢复排除DATAMART 表空间的备份集：

rman target /

RMAN> startup nomount

RMAN> restore controlfile from '/backup/ctl_OEM_914692212_78_1';

RMAN> alter database mount;

RMAN> restore database skip tablespace DATAMART ;

RMAN>recover database skip tablespace DATAMART ;
