本文当主要以数据库恢复为主,操作系统安装、数据库安装配置和NBU客户端安装配置忽略；
1. 确定要恢复的数据库信息，如果数据库和操作系统可以正常访问，则可以登录数据库和操作系统查看和恢复信息相关的信息，如果数据库甚至是操作系统不可访问，则可以参考《oracle数据库信息收集》文档，里面记录了oracle数据库恢复的相关信息；
2. 为了确保恢复后的数据库可以尽快使用，尽量减少应用程序的修改，恢复完以后修改主机IP地址和原数据库地址保持一致；
1. 根据《oracle数据库信息收集》文档，安装操作系统和数据库软件，其中操作系统的版本尽量相同，数据库版本则需要一致；
2. 根据《oracle数据库信息收集》文档，挂载合适的存储，主要是存储的大小，所挂载的存储不可小于要恢复的数据库总容量大小，并配置合适的ASM磁盘组，磁盘组的大小和名称建议原来一样，磁盘组的容量可以大于原磁盘组；
3. 在客户端安装好NBU client，并保证通过NBU client可以正常访问备份文件；
在操作系统上执行如下命令：
/usr/openv/netbackup/bin/bplist -C fxzmd -t 4 -l -R /
列出数据库备份信息，部分信息如下：

最后重启下数据库，恢复完成；
lsnrctl start
1. 创建pfile：
SQL> create pfile='/home/oracle/initfxzmd.ora' from spfile;
2. 创建spfile：
SQL> create spfile='+DGROUP1' from pfile='/home/oracle/initfxzmd.ora';
3. 修改pfile：
在$ORACLE_HOME/dbs下创建initfxzmd.ora文件，内容如下：
SPFILE='+DGROUP1/FXZMD/PARAMETERFILE/spfile.259.856714109'
4. 删除$ORACLE_HOME/dbs下的spfile，重启数据库：
SQL> show parameter spfile;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
spfile string +DGROUP1/fxzmd/parameterfile/spfile.259.856714109
修改成功，spfile成功放入ASM磁盘组中；
5. 为了才dbca中能正常看到恢复过来的数据库，需要在
/etc/oratab 文件结尾添加如下内容：
fxzmd:/app/oracle/product/10.2/db_1:N
6. 最后做一个数据库全备！
