RMAN异机复制数据库（不同路径）

1、恢复参数文件

设置环境变量：

export ORACLE_SID=hncdfhq

登录RMAN:

rman target /

在RMAN里把数据库起到nomount状态：

startup nomount;

设置DBID:

set dbid=3950123605

恢复spfile：

restore spfile from '/oradata2/backup/c-3950123605-20140616-05';

关闭数据库：

shutdown immediate;

把数据库起到nomount状态：

startup nomount;

2、恢复控制文件

通过spfile创建pfile

SQL> create pfile from spfile;

修改参数文件中控制文件的路径

关闭数据库

删除spfile或者重命名为别的名字

启动数据库到nomount状态

通过pfile创建spfile

关闭数据库

启动数据库到nomount状态

RMAN> restore controlfile from '/oradata2/backup/ctl_HNCDFHQ_20140616_195_1';

RMAN> alter database mount;

3、恢复数据文件

如果备份不在备份时所在的目录，在新的目录。

可以用此命令注册到控制文件。

RMAN> catalog start with '/oradata1/backup';

SQL> col name for a40

SQL> col file# for 999

SQL> set pagesize 999

SQL> select file#,name from v$datafile;

原来路径为 /oradata2/hncdfhq

现在要更改的路径为 /oradata2/oracle

SQL> alter database rename file '/oradata2/hncdfhq/redo03.log' to '/oradata2/oracle/redo03.log';

更改临时表空间的位置

SQL> select ts.name,tf.name from v$tablespace ts ,v$tempfile tf

2  where ts.ts#=tf.ts#;

用操作系统命令移动文件

SQL> alter database rename file '/oradata2/hncdfhq/temp01.dbf' to '/oradata2/oracle/temp01.dbf';

SQL> alter database rename file '/oradata2/hncdfhq/temp_spc01.dbf' to '/oradata2/oracle/temp_spc01.dbf';

SQL> recover database using backup controlfile until cancel;

--选择redo的绝对路径，一个一个试，有多少组redo，就试多少次

SQL> alter database open resetlogs;
