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
