使用Rman结合netbackup重定向恢复ORACLE数据库
网上使用netbackup异机恢复oracle数据库完整的例子不多，由于公司的环境所致，花了些时间做了个恢复测试，以下是恢复测试，共享大家，欢迎拍砖。*****实施环境*****
数据库服务器：eagle （原主机）
NBUserver：sol1（NBU备份服务器）
异机数据库：sol2（目标主机）
*****恢复的前提条件*****
1、日常数据库备份成功。至少有一次全备份和Archivelog.
2、原主机的OS及ORACLE版本与目标主机的OS及ORACLE版本保持一致.
3、需要原数据库、NBUserver的下列信息：
3.1、IP Address, Hostname, Nbu media server name（NBU备份服务器） /client name（原主机）
3.2、Oracle DB version,SID,DBID,Datafile Path,Controlfile Path,Archivelog Path
3.3、在目标主机上安装与原数据库版本相同的oracle软件，不创建数据库。
3.4、在目标主机上安装NbuClient软件、DBagent服务，安装类型与原主机一致。
*********************************各主机软件安装情况*********************************
1、数据库服务器：eagle （原主机）
oracle9.2.0.6 Server/oracleAgent/NBUClient6.5
2、NBUserver：sol1(NBU备份服务器)
NBUServer6.5
3、异机数据库：sol2（目标主机）
oracle9.2.0.6 Server/oracleAgent/NBUClient6.5
*********************************恢复步骤*********************************
目标主机sol2配置
1、安装NBUClient6.5
1.1、拷贝带有NBUClient的65_DVD1_20070723.iso
# ls
65_DVD1_20070723.iso 65_DVD2_20070723.iso
1.2、挂载iso文件
# lofiadm
Block Device File
# pwd
/opt/nbufile
# lofiadm -a /solairs 10 iso
lofiadm: open: /solairs: No such file or directory
# lofiadm -a /opt/nbufile/65_DVD1_20070723.iso
/dev/lofi/1
#
# mkdir /mnt/iso
# mount -F hsfs /dev/lofi/1 /mnt/iso/
# cd /mnt/iso
# ls
IA64 NB_65_ICS_1.4.37.3_WIN32 X86 x64
Launch.bat NB_65_ICS_1.4.37.3_WINIA64 autorun.inf
NBClients NB_65_ICS_1.4.37.3_WINX64 install
#
1.3、开始安装NBUClient
# ./install

2、安装NBUClient6.5
2.1、挂载iso
# ls

#
3、安装Oracle 9.2.0.1 升级至 9.2.0.6（此步骤略过）
3.1、将$ORACLE_HOME/dbs/pfile、spfile、pwdfile拷贝至目标数据库相同目录
3.2、根据参数文件中参数指向的目录创建，bdump、cump、udump及归档路径
-bash-3.00$mkdir /oracle/app/admin/china111/bdump
-bash-3.00$mkdir /oracle/app/admin/china111/cdump
-bash-3.00$mkdir /oracle/app/admin/china111/udump
-bash-3.00$mkdir /oracle/archive
4、目标主机sol2的nbuClient、hosts文件配置
4.1、创建$ORACLE_HOME/bp.conf file
#cd $ORACLE_HOME
#vi bp.conf
SERVER = sol1 /*master server name*/
CLIENT_NAME = eagle /*source host name*/
CLINET_READ_TIMEOUT = 1800
4.2、编辑/usr/openv/netbackup/bp.conf
#vi bp.conf
SERVER = sol1 /*master server name*/
CLIENT_NAME = eagle /*source host name*/
CLIENT_NAME = sol2 /*target host name */
VERBOSE = 5
CLIENT_READ_TIMEOUT = 1800
CLIENT_CONNECT_TIMEOUT = 1800
4.3 编辑/etc/hosts文件
#vi /etc/hosts
#
# Internet host table
#
::1 localhost
127.0.0.1 localhost
192.168.45.12 sol2 loghost sol2.company.igocctv.com.
192.168.45.11 sol1
192.168.43.180 autosvr
#AD Use
192.168.45.10 company.igocctv.com
5、NBUserver主机的nbu、hosts文件配置
5.1、创建文件允许进行重定向恢复主机
#cd /usr/openv/netbackup/db/altnames
#touch sol2 /*target host name */
#cd /usr/openv/netbackup/db/altnames
#touch No.Restrictions
5.2、编辑/etc/hosts文件
#vi /etc/hosts
# vi /etc/hosts
#
# Internet host table
#
::1 localhost
127.0.0.1 localhost
192.168.45.11 sol1 loghost sol1.company.igocctv.com.
192.168.45.12 sol2
192.168.43.101 swallow1
192.168.43.102 swallow2
192.168.43.151 swallow3
192.168.43.152 swallow4
192.168.43.180 autosvr
192.168.43.2 eagle
6、开始恢复数据库
6.1、使用pfile或spfile在目标主机（sol2）上启动数据库到nomount 状态

6.2、rman恢复数据库
首先在NBUserver端找到有效的备份文件，其中/cntrl_2602_1_753766268为最新的控制文件
