1. 环境：
原机： 192.168.102.156
目标机： 192.168.102.157

2. 需求： 只有数据文件的备份和归档日志的备份 ， 无控制文件备份， 并将备份恢复到 /home/oracle/oradata/datafile下。

3. 参数文件准备
3.1 在原库生成PFILE文件。
SQL> create pfile=’/home/oracle/initgg1.ora’ from spfile;

File created.
3.2  奖参数文件移至目标库。
[oracle@GOLDENGATE1 ~]$ scp initgg1.ora oracle@192.168.102.157:/home/oracle
oracle@192.168.102.157′s password:
initgg1.ora                                                                                                100% 1051     1.0KB/s   00:00

4. 将目标库启动至NOMOUN状态。
4.1 修改参数文件：
*.control_files=’/home/oracle/oradata/datafile/control01.ctl’,'/home/oracle/oradata/datafile/control02.ctl’,'/home/oracle/oradata/datafile/control03.ctl’
*.core_dump_dest=’/home/oracle/admin/gg1/cdump’

4.2 创建PFILE所需要的目录。
[oracle@GOLDENGATE2 ~]$ mkdir -p admin/gg1/adump
[oracle@GOLDENGATE2 ~]$ mkdir -p admin/gg1/cdump
[oracle@GOLDENGATE2 ~]$ mkdir -p admin/gg1/bdump
[oracle@GOLDENGATE2 ~]$ mkdir -p admin/gg1/udump
[oracle@GOLDENGATE2 ~]$ mkdir oradata/datafile

4.3 将目标库启动到NOMOUNT状态。
[oracle@GOLDENGATE2 ~]$ export ORACLE_SID=gg1
[oracle@GOLDENGATE2 ~]$ sqlplus / as sysdba

5. 备份文件准备。
5.1 备份原库：

从上面的内容可以看出这里的控制文件已经做了备份， ORACLE 从10G以后就自动备份控制文件和SPFILE文件。  这里我们还是继续往下做。

5.2 将备份文件移至目标机：
[oracle@GOLDENGATE1 rman]$ scp * 192.168.102.157:/home/oracle/rman
oracle@192.168.102.157′s password:
