1.创建数据库目录
2.从原来主机复制pfile文件，并更改oracle_sid
vi .bash_profile source .bash_profile
3.启动数据到nomount状态
$ sqlplus / as sysdba SQL> startup nomount pfile=‘pfile文件绝对位置‘; ORACLE instance started. SQL> exit
4.查看备份controlfile列表
$ /usr/openv/netbackup/bin/bplist -S 备份服务器 -C 备份客户端 -t 4 -s 09/10/2000 -e 09/11/2000 -R -l / 该命令中-s参数后面接开始日期，-e参数接结束日期，表示获取该时间段内的控制文件列表
5.恢复controlfile文件
$ rman target /
RMAN>
run{
allocate channel a0 type ‘sbt_tape‘;
allocate channel a1 type ‘sbt_tape‘;
send ‘nb_ora_serv=备份服务器 , nb_ora_client=备份客户端‘;
restore controlfile from ‘ cntrl_xxx_x_xxxxxxxxx‘; #控制文件名由上一步骤中得到
release channel a0;
release channel a1;
}
RMAN> exit
注意：在这里报错
RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03009: failure of allocate command on a0 channel at 06/14/2011 11:45:03 ORA-19554: error allocating device, device type: SBT_TAPE, device name: ORA-27211: Failed to load Media Management Library race文件发现没有libobk.so所致,拷贝libobk.so至oracle安装目录下的lib/下面 cp /usr/openv/netbackup/bin/libobk.so64.1 /opt/oracle/product/9.2/lib/libobk.so 或者做一个软链接 ln -s /usr/openv/netbackup/bin/libobk.so64 /opt/oracle/product/9.2/lib/libobk.so
6.启动数据库到mount状态
$ sqlplus / as sysdba SQL> alter database mount; Database altered. SQL> exit
7.恢复数据库
$ rman target /
run{
allocate channel a0 type ‘sbt_tape‘;
allocate channel a1 type ‘sbt_tape‘;
allocate channel a2 type ‘sbt_tape‘;
allocate channel a3 type ‘sbt_tape‘;
send ‘nb_ora_serv=备份服务器 , nb_ora_client=备份客户端‘;
restore database;
recover database;
release channel a0;
release channel a1;
release channel a2;
release channel a3;
}
8.Reset log 打开数据库
$ sqlplus / as sysdba SQL> alter database open resetlogs;
