1，目前控制文件只有一个，为了安全性，计划增加到3个
SQL> select name from v$controlfile;
NAME -------------------------------------------------------------------------------- +DATA/tyolap/controlfile/current.256.772291325 2，执行如下sql
alter system set control_files = '+DATA/tyolap/controlfile/control01.ctl','+DATA/tyolap/controlfile/control02.ctl','+DATA/tyolap/controlfile/control03.ctl' scope=spfile;
3，停止数据库 [grid@dtydb3 ~]$ srvctl stop database -d tyolap
4，复制控制文件 ASMCMD> pwd +data/TYOLAP/CONTROLFILE ASMCMD> ls Current.256.772291325 test.ctl ASMCMD> cp Current.256.772291325 control01.ctl copying +data/TYOLAP/CONTROLFILE/Current.256.772291325 -> +data/TYOLAP/CONTROLFILE/control01.ctl ASMCMD> cp Current.256.772291325 control02.ctl copying +data/TYOLAP/CONTROLFILE/Current.256.772291325 -> +data/TYOLAP/CONTROLFILE/control02.ctl ASMCMD> cp Current.256.772291325 control03.ctl copying +data/TYOLAP/CONTROLFILE/Current.256.772291325 -> +data/TYOLAP/CONTROLFILE/control03.ctl ASMCMD>
5，重新启动数据库 [grid@dtydb3 ~]$ srvctl start database -d tyolap 6，验证结果
SQL> select name from v$controlfile;
NAME -------------------------------------------------------------------------------- +DATA/tyolap/controlfile/control01.ctl +DATA/tyolap/controlfile/control02.ctl +DATA/tyolap/controlfile/control03.ctl
