RAC和ASM环境下修改控制文件control file

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
