思路：1、在数据库中先创建一个新的redo组放在data的磁盘组中2、切换日志文件以便原redo的信息都已归档，并且所有的redo状态为变为inactive3、在asm中执行drop diskgroup 删除磁盘组步骤：1 添加redo组备注：由于在测试环境的RAC里有REDO的磁盘组，但是我查看redo文件并没有在这里，所有我现在创建redo组9到redo的磁盘组中。SQL> alter database add logfile group 9 ('+REDO_ORCL','+REDO_ORCL') size 50m; Database altered. SQL>select g.group#,g.members,g.archived,g.status,e.member from v$log g,v$logfile e where g.group#=e.group# order by g.group#; GROUP#MEMBERS ARC STATUS MEMBER---------- ---------- --- ---------------- -------------------------------------------------- 1
