以前控制文件只有一个:

NAME                                 TYPE        VALUE

———————————— ———– ——————————

control_files                        string      +DATA/orcl/controlfile/current

.264.792324619

步骤:

1.修改初始参数:

alter system set c,’+data/orcl/controlfile/control02.ctl’ scope=spfile;

2.停止数据库

sql>conn / as sysdba

sql>shutdown immediate;

3.启动数据库到nomount状态

sql>conn / as sysdba

sql>startup nomount;

4.使用rman 恢复控制文件

$ rman target /

rman>restore controlfile from ‘+DATA/orcl/controlfile/current.264.792324619’;

5.打开数据库

sql>conn / as sysdba;

sql>alter database mount;

sql>alter database open;

6.验证控制文件

sql>show parameter control_files
