1.首先准备工作：
hostname
192.168.222.11 ol7.localdomain ol7
建立相关目录：
mkdir -p /u01/app/oracle/oradata/DB11G/
mkdir -p /oracle/redo1/
mkdir -p /u01/app/oracle/product/11.2.0.4/db_1/dbs/
mkdir -p /oracletemp/DB11G/archive_log/
mkdir -p /oraclearch/archive_log/
mkdir -p /oraclearch/flash_recovery_area/DB11G/
mkdir -p /u01/app/oracle/oradata/DB11G/
mkdir -p /oracledata/nc/ncindex/
mkdir -p /u01/app/oracle/oradata/DB11G/
mkdir -p /oracledata/nc/nctables/
mkdir -p /oracledata/DB11G/
mkdir -p /u01/app/oracle/oradata/DB11G/
mkdir -p /u01/app/oracle/admin/DB11G/{adump,dpdump,pfile}
chown -R oracle:oinstall /u01
chmod -R 775 /u01
chown -R oracle:oinstall /oracle/redo1/
chmod -R 775 /oracle/redo1/
chown -R oracle:oinstall /oracletemp/DB11G/archive_log/
chmod -R 775 /oracletemp/DB11G/archive_log/
chown -R oracle:oinstall /oraclearch/archive_log/
chmod -R 775 /oraclearch/archive_log/
chown -R oracle:oinstall /oracledata/nc/ncindex/
chmod -R 775 /oracledata/nc/ncindex/
mkdir /oracledata/nc_ma/nc_ma_tables/ -p
chown oracle:oinstall -R /oracledata/nc_ma/nc_ma_tables/
更新yum update
执行脚本：
[root@ol7 ~]# cat dbinstall.sh
#!/bin/bash
IP=`ip addr |grep 'inet'|grep 'brd'|awk '{print $2}'|awk -F / '{print $1}'`
echo $IP ol7.localdomain ol7 >> /etc/hosts
hostnamectl set-hostname ol7.localdomain
sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config
setenforce 0
yum -y install oracle-rdbms-*
yum -y install rlwrap
mkdir -p /u01/app/oracle/product/11.2.0.4/db_1
chown -R oracle:oinstall /u01
chmod -R 775 /u01
systemctl stop firewalld
systemctl disable firewalld
cat >>/home/oracle/.bash_profile<<EOF

再次执行脚本：
[root@ol7 ~]# cat iso.sh
#!/bin/bash
yum install createrepo -y
yum install unzip -y
yum install gcc* -y
yum install xhost -y
yum -y install elfutils*
[root@ol7 ~]#
解压：
/u01/app/oraInventory/orainstRoot.sh
/u01/app/oracle/product/11.2.0.4/db_1/root.sh
二：在目的服务器上复制备份数据，并准备好相关的目录
[oracle@orcl ~]$ mkdir /u01/backup
[oracle@orcl ~]$ scp -rp 192.168.227.20:/u01/backup/* /u01/backup/
oracle@192.168.227.20's password:
control20110906.bak 100% 6944KB 1.7MB/s 00:04

spfile20110906.bak 100% 96KB 96.0KB/s 00:00

[oracle@orcl ~]$ mkdir -p /u01/app/oracle/admin/orcl/{adump,bdump,cdump,dpdump,udump,pfile}
[oracle@orcl ~]$ mkdir -p /u01/app/oracle/oradata/orcl
[oracle@orcl ~]$ mkdir -p /u01/app/oracle/flash_recover_area/ORCL
三：在目的服务器上进行恢复
[oracle@orcl ~]$ echo 'db_name=orcl' > $ORACLE_HOME/dbs/initorcl.ora
[oracle@orcl ~]$ export ORACLE_SID=orcl
[oracle@orcl ~]$ rman target /

五：注意事项
RMAN> list incarnation; //生成一个新的incarnation
using target database control file instead of recovery catalog

List of Database Incarnations
DB Key Inc Key DB Name DB ID STATUS Reset SCN Reset Time
------- ------- -------- ---------------- --- ---------- ----------

3 3 ORCL 1287906064 CURRENT 547975 2011-09-06:17:07:09

[oracle@orcl ~]$ emctl start dbconsole //dbconsole需要重新配置，orapwd文件也需要创建
TZ set to PRC
首先：
/u01/app/oracle/product/11.2.0.4/db_1/dbs
orapwd file='/u01/app/oracle/product/11.2.0.4/db_1/dbs/orapwDB11G' password=oracle entries=5 force=y;
OC4J Configuration issue. /u01/app/oracle/product/10.2.0/db_1/oc4j/j2ee/OC4J_DBConsole_orcl.herostart.com_orcl not found
然后：
你按着这个顺序来试试，不行的话我也不会了

1、设置好监听器，用lsnrctl start启动，然后用lsnrctl statu观察一下是否成功
2、emca -deconfig dbcontrol db 删除dbcontrol
3、emca -repos drop删除EM资料库
4、emca -repos create创建资料库
5、emca -config dbcontrol db重新配置dbcontrol

如果能顺利做下来就应该没问题了

ok!!!!!
