注意：本文档操作系统环境以Linux为主，假设要恢复金融数据库；

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；

要恢复的数据库信息：

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；

准备环境：

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；

恢复步骤：
恢复文件说明:

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：

Spfile

创建pfile 修改pfile文件：

SQL> create pfile='/home/oracle/initfxzmd.ora' from spfile;

File created.

编辑pfile：

根据$ORACLE_BASE、$ORACLE_HOME创建相应的目录：

mkdir –p /app/oracle/admin/fxzmd/adump

mkdir –p /app/oracle/admin/fxzmd/bdump

mkdir –p /app/oracle/admin/fxzmd/cdump

mkdir –p /app/oracle/admin/fxzmd/udump

用修改过的pfile 创建spfile：

关闭数据库：

SQL> shutdown immediate

ORA-01507: database not mounted

ORACLE instance shut down.

用新的pfile启动数据库到nomount：

SQL> startup nomount pfile='/home/oracle/initfxzmd.ora';

database opened

最后重启下数据库，恢复完成；

数据库正常恢复后配置：
修改主机的IP地址：
启动监听：

lsnrctl start

把spfile从文件系统放到ASM磁盘组中：

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！
