生产环境是2个节点的rac + dataguard（物理备库也是两个节点的rac），通过rman每天进行备份，现在需要定期对生产库进行恢复操作
恢复步骤如下：
1. 把生产库的备份拷贝到目标端
建立存放备份的目录修改目录属主属组
mkdir /oracle/backup
chown oracle:oinstall /oracle/backup
2. 拷贝备份到目标端
scp -P 22 incremental_level* oracle@ip:/oracle/backup
scp -P 22 ctrl_ORCL_1381360903 * oracle@ip:/oracle/backup
scp -P 22 arch_ORCL_ * oracle@ip:/oracle/backup
3. 构造参数文件
在rac环境上生产pfile文件，然后修改pfile文件如下：
把rac相关的参数注释掉，修改相应的参数为单实例数据库上的路径

文件修改好后放到$ORACLE_HOME/dbs下并命名为initorcl.ora
4. 创建相关的目录
mkdir –p /oracle/oracle/oradata/archive --归档目录
mkdir –p /oracle/oracle/admin/orcl/adump --跟踪审计目录
mkdir –p /oracle/oracle/oradata/orcl --数据文件存放目录
chown oracle:oinstall /oracle/oracle/oradata/archive
chown oracle:oinstall /oracle/oracle/admin/orcl/adump
chown oracle:oinstall /oracle/oracle/oradata/orcl
5. 设置oracle_sid环境变量用编辑的好参数启动数据库到nomount状态

恢复步骤如下：
1. 把生产库的备份拷贝到目标端
建立存放备份的目录修改目录属主属组
mkdir /oracle/backup
chown oracle:oinstall /oracle/backup
2. 拷贝备份到目标端
scp -P 22 incremental_level* oracle@ip:/oracle/backup
scp -P 22 ctrl_ORCL_1381360903 * oracle@ip:/oracle/backup
scp -P 22 arch_ORCL_ * oracle@ip:/oracle/backup
3. 构造参数文件
在rac环境上生产pfile文件，然后修改pfile文件如下：
把rac相关的参数注释掉，修改相应的参数为单实例数据库上的路径

文件修改好后放到$ORACLE_HOME/dbs下并命名为initorcl.ora
4. 创建相关的目录
mkdir –p /oracle/oracle/oradata/archive --归档目录
mkdir –p /oracle/oracle/admin/orcl/adump --跟踪审计目录
mkdir –p /oracle/oracle/oradata/orcl --数据文件存放目录
chown oracle:oinstall /oracle/oracle/oradata/archive
chown oracle:oinstall /oracle/oracle/admin/orcl/adump
chown oracle:oinstall /oracle/oracle/oradata/orcl
5. 设置oracle_sid环境变量用编辑的好参数启动数据库到nomount状态
